Every time I had a “new” idea, I’d eventually discover three dead startups around the exact same thing. Usually after days :) So I built Déjà View. You describe an idea, and it researches its real-world predecessors: companies that tried it before, when they operated, when they shut down and who survived.
It’s live at https://dejaview.bsct.so Try it on your current idea and tell me if the report found anything you didn’t know about!

Hi all,
I had this idea in my head for some time, and today I used one of the vibe coding tools to make an MVP. I am sharing it here in hope that someone will take a moment to check it and give some feedback (on the idea).

It is a drawing tutorial with focus on the concepts. It is easy to say someone draw a line, but it is easier to someone to hear "an ear is from eyebrows to nose level" and show them how the lines look like. With this app, tutorials are split into easy to process steps, and users can draw over projected lines to get the final image. If there is too much deviation, drawing will need to be repeated.

App is currently deplyoed to Vercel and has only one tutorial, but after idea validation I would work on it more.

App: https://sketched-tawny.vercel.app/

Thanks to anyone who checks it, and special thanks to anyone who writes me anything
Cheers

Hi, I have had this idea for a while. I'm very forgetful, and the basis of how I recall, I have noticed, is: say I said "I wish I had a burger," then I go to the same location again, I'll remember the otherwise forgotten information. And more dumb things, like certain conversations are very impactful but have no direct way of holding them to memory. Say I wanted to "solve LeetCode today," in the next one hour I would have no trace of the thought.

"Ever tried using a free app called Notes?" you ask?

Of course I have: temporary, permanent, habits, short term, and long term, and just so many more. Sometimes I'm surprised when I read through them. The thought I would have thought was a realization from the past month would have already been realized 3 years ago. The path I thought I decided recently would have drafts of planning from a year ago.

I don't know if I'm neurodivergent, but I definitely have a very scrawny brain, with my everyday life looking almost the same; it's very hard to think of things. It's like I wanna do something, but I forget and redo the entire ideation process.

My solution that somewhat works is a mind map/vision board. I have shit drawn (it works perfectly, I haven't led astray for a solid time now).

And so I thought, why not bring this to life with a widget where people add, say, images (to represent visual info)? Say, "I was talking to my boyfriend about studies over coffee," and I take a pic of the coffee. Every time I look at it, I recall, "Why did I put it there?" (Since I won't see it once, in 5 years I'll most likely be able to recall it), and it will be in the front of my mind till I wish to delete it. But not all things are of the same priority. So, instead of giving them all the same size, on tap they resize. The bigger the box, the more pressing the task at hand is, or a habit to build, and the more prominent the "cue" to generate the thought is. I believe constant (inevitable) repetition will solidify our sense of, say, purpose or path. We live in an over-simulated world, after all; we need some way of staying on track.

To me, this is an alternative to a visual jamboard-like journal that changes with you as you remove unnecessary jargon and refine your life.

What do you guys think? It's a little tricky to build, and I failed twice miserably. I know I'll use it, but I don't know if it's actually useful.

(Ps: please be gentle, i have a fragile heart)

Main Idea

So, what I mean by "AI Prompt Management & Engineering” Platform is somewhere where you can store, organize, experiment, version, analyze prompts. So like users who need to handle multiple prompts, make them better or keep track of edits/versions, know how well one performs like in multi-agent systems or workflows like data analysis, research, etc.

Possible Features

• Prompt Storage: Store Prompts according to workspaces and projects.
• Prompt Versioning: Save/Commit the latest edits of a prompt while keeping track of past ones
• Prompt Experimentation: Run prompts with different configurable parameters (including temperature or max tokens) on many supported LLM models from multiple providers. Compare versions of a prompt, or different LLM models on a prompt on cost, latency and quality
• AI Features: Create a full working prompt from scratch using AI. Also able to improve and evaluate prompts using AI
• Analytics & Tracking: Keep track of run history, cost, usage, etc.
• Other small features: Project Context (for better results), Save best parameters (so you always come back to the desired running parameters for a prompt. Referrals (for free rewards). Maybe even going into deployment and collaborative spaces?

Competitors

Yes, a competitive space but this provides features of multiple different products together. What is your say on this?

---------------------------------------------------------------------

Soooo, what do you guys think on such a idea? What could be added, changed and what is missing? Would a product be good? Or is the competition too much? Looking forward for feedback!

I am currently building an app and what a ride it has been, out of curiosity if you have an app or website what is it? Is it your full time job? And how much did you make in your best month?

Most AI interior-design apps give you a single generated image.

I wanted to see whether it would be more useful to scan your actual room, redesign the complete space and then experience it from different angles before buying furniture or renovating.

The room was captured using an iPhone. The app then created a redesigned version that can be explored by moving around and looking through the phone.

I’m currently trying to understand three things:

- Is a walkable result meaningfully more useful than a normal AI-generated image?

- What would you need to trust the design enough to use it for a real furniture decision?

- Would you expect to pay per room, or use this through a subscription?

Any input will be helpful.

Any steam user here prob knows that it feels good getting those small, sometimes big achievements. An app for getting achievements while also doing activities would be really cool. For example you will get an achievement named "A long trip" for running over 3 miles in a day, or you can get a achievement named "back to the stone age" if you dont use the internet for a whole day. It would also be cool to have daily and weekly challanges. There could also be community achievements for hundreds of them (custom made achievements other than the original ones).

I am highly ambitious, but I also get distracted by things constantly, and end up losing an hour doing something I never meant to do in the first place. It eats away at the time I actually have for important work, and the wasted hours just pile up over a week. I tried blockers on my phone, focus timers, Pomodoro, basically everything. Nothing stuck.

I primarily work in content creation, script writing and video editing need a lot of undivided attention, and it is so hard to hold onto. Most blockers are built for the phone, but most of my actual work happens on my Mac. I drift from a Google Doc to YouTube without even realizing it happened. So I decided to build something myself.

The idea I landed on: name one result before you start, run a protected session around it, and let the app defend it. Not a blanket lockout, just the specific things that pull you off that specific piece of work. On the Mac, it actually reads what tab is in front of you (no screenshots or keystrokes), not just which app, so it catches the Docs to YouTube slide before I have lost twenty minutes to it. It pairs with the iPhone too, one session, both devices, either one can start it or end it.

If I drift or get stuck, it pulls me back with one tap instead of just nagging. And it does not end when a timer runs out, it ends when I say what actually changed. A scene finished, a script edited, a cut exported, not just how long I sat there. That was the piece I actually needed. Time sitting at my desk was never the problem, finishing the thing was.

There is a lightweight accountability partner feature too right now, pretty bare bones, you link with someone and they only see a commitment title and whether you hit it. I think this is the most under built part of it, and it is genuinely where I want feedback: would a live "in a session right now" status matter to you? A shared weekly proof feed? Even matching with a stranger for a working session instead of needing to already know someone first?

It is live on TestFlight now, iPhone and Mac. Pricing is designed, free keeps the core loop usable, Pro would be around $5 a month, but it is not switched on yet, still building the waitlist.

If you do creative or deep focus work and end up somewhere you never meant to be, does something like this actually solve it for you? What would make the partner feature worth using? What is missing entirely?

Give me your feedback and questions. I'll be happy to take them.

After about a year of evenings, weekends, late nights, rewrites, and more bugs than I can count, I finally shipped my app.

The idea came from something I kept noticing: we can connect with people on the other side of the world instantly, but we rarely meet the interesting people sitting right next to us at cafés, conferences, universities, or airports.

So I spent the past year trying to build something that makes those real-world connections a little easier, while putting privacy first.

This isn't AI slop or a weekend vibe-coded project. It's something I've been building, breaking, rebuilding, and obsessing over for the past year.

Watching complete strangers sign up and use something that only existed in my head a year ago has been a surreal feeling. It reminded me why all those late nights were worth it.

If you're currently doubting yourself or struggling to get your own app out the door, hang in there. Keep shipping. Keep fixing. Keep learning.

There's no better feeling than seeing strangers use something you built. That feeling never gets old.

Most habit trackers fail because nothing happens when you fail. So I started thinking about an app where failing your goal actually has a consequence. You set a goal like working out, quitting smoking, shipping your side project, or finally posting videos consistently.

Before you start, you record a penalty video you'd never want your friends to see. To activate the contract, you have to send a unique link to a few friends. They can see your goal and a countdown, but the video stays locked.If you succeed, the video is permanently deleted.If you fail, the page unlocks and your friends can finally watch it.

Does this solve a real problem for you, or would you never use it? Why?

Random idea I had today.

Imagine a dating app where you can’t see the other person’s photo at first.

You only know basic information:

First name
Age
General location
Interests

You match and start talking.

No pictures.
No swiping based on looks.

After you’ve genuinely gotten to know each other (or after a set amount of time), the app reveals both of your photos at the same time.

The goal is simple: build a connection before appearance becomes part of the equation.

Would this completely fail because physical attraction matters too much?

Or do you think there are people who are tired of swipe culture and would actually give this a shot?

I’m genuinely curious. What would make you download—or immediately delete—an app like this?

I've been looking at apps like Forest and a few upcoming ones, and most of them pile on streaks, leaderboards, cosmetics, social challenges, XP systems... it starts feeling like managing a second app instead of using less of my phone.

I'm considering building a much simpler version: an animal pet whose health just reflects your recent usage, no scores, no social layer. If you keep doomscrolling it gets visibly anxious, and if it's really struggling, you can use an "emergency" item to help it recover faster, but you mostly earn that by actually cutting back, not by grinding challenges.

Genuine question: would something stripped-down like that actually get used, or do people want the gamified depth (levels, streaks, social stuff) to stay engaged long-term?

Why do we accept that being connected online means giving up on knowing what's real, and that protecting your privacy means giving up on being part of anything public? Genuinely asking, not rhetorically -is that just how it has to work, or is that a gap nobody's actually tried to close?

This isn't hypothetical for me. I watched a country's information environment collapse in real time - recycled footage, wrong captions, genuinely no way to know what was happening - and it's stuck with me ever since. I've been sketching out an idea around it: a social app where the public side is built to earn your trust instead of asking you to blindly trust an algorithm, and the private side stays actually private, no exceptions, ever.

Wireframes attached, very early stage. Before I go further I want to actually stress-test the idea itself - is "connection without giving up on trust or privacy" a real gap, or is it just a nicer way of describing something that already exists and I haven't noticed? And separately: what's the one thing you personally stopped expecting to be true on your own feed, the thing you just quietly gave up on?

I was so addicted to reels and youtube shorts that i can't even focus on my studies for half an hour.

So I built a small tool for myself that takes my notes/PDFs and turns them into short swipeable cards - like a Tik Tok/Reels feed but each card is a concept, with some lofi music and a voice reading it out so I can review while lying down or walking instead of staring at a doc. It's a bumb idea but instead of doomscrooling on instagram, scroll in your notes. At least you can learn something that will help you in your exams.

I tend to work on things for too long before getting feedback, so I’m trying to share this earlier.

I’m working on an app for busy home cooks who are too tired to plan and cook on weeknights. Parents, busy professionals. You tell it what is in your pantry and what your week looks like, and it turns that into a meal plan and grocery list based on recipes that I curate

Since I can’t post the landing-page link here, I’ve attached screenshots instead. My specific questions are below, but I appreciate all feedback.

1. Looking only at the first screenshot for five seconds, does the value of my app come across clearly?

2. The three main promises are deciding what to cook, using ingredients you already have, and turning the plan into a grocery list. Which one would matter most to you, and why?

3. If weeknight cooking often feels tiring or hard to plan, would this help you? If not, what might make it worth trying?

Thank you!!

I'm on iOS and, like pretty much everyone with an iPhone, I use Safari as my main browser. And the thing that's been driving me nuts for years is that there's no translator on it I can actually rely on.

Safari built-in translator sucks, it doesn't support so many languages I need (no Thai, no Georgian for example).

Apple has historically been pretty bad when it comes to languages support, so I don’t expect the situation to improve anytime soon.

Where it really gets me is traveling. I'll be somewhere abroad trying to open the local site, and there's no English anywhere, or the translator does maybe half the page and leaves the rest sitting there in a language I can't read.

I tried so many iOS apps (on iOS a browser ext has to be an app) and I'm not satisfied with every single one of them. A lot just don't work at all.

So I decided to build my own

Here's what I'm focused on:

• good iOS Safari support that doesn't break. It has to handle the cursed stuff, shadow DOM, iframes, dynamic content like modal windows, popups etc, all the hacky frameworks - I spend a lot of time on the translation engine
• ability to set it as your default iOS translator, so when you select text anywhere and press "Translate" - it opens my translator instead of the built-in one (iOS supports that)
• voice input (whisper like, with good language support)
• ability to send screenshots, PDFs, acticles (with reader mode support), all that
• alternative translations (styles)
• a "rephase" mode - when you're the one replying and don't want to sound like a tourist

Desktop browsers (Chrome, Firefox) will also be supported.

It's not out yet, but I'm really close to releasing it.

Anyone interested? Any features requests?

Hey,

I have a problem in my daily life, both at work and personally. I have a Google Calendar that's fulled, and every time I delay, miss, or reschedule an event, all the following events get shifted, misplaced, and in my case usually cancelled. Often never actually completed because of this constant shifting...

I came up with a workflow that would automatically readjust your calendar to prioritize the most important events and accomplish tasks with deadlines for exemple. I've been using it for a while now and it's been a huge help !
For example: if a task takes longer than expected, the least important events are either moved, shortened if possible, or cancelled and pushed to another day in the worst case.

The workflow would adapt to your habits and learn to anticipate by suggesting changes based on how long similar events have taken in the past (weekly meetings taking longer than expected).

So right now, I'm simply asking: does this problem affect you too, and would a workflow like this solve this problem ? How much would you be willing to pay for a tool like this ? What would you want to see in such a tool.
Every feedback is important for me.

Thanks!

ok so im 18, half american half japanese, and i vibe coded this thing over a few weeks. honestly not sure if its a real idea or just a me problem, so i wanted to bring it to ppl who actually think about this stuff before i sink more time in.

the idea: Curae (curae.life), a site to help ppl who dont speak japanese find an english-speaking doctor in japan. u browse clinics by area/specialty, and the goal is you send a booking request in your own language and it handles the japanese side.

why i care: im half japanese and basically grew up being the Translator for family + friends, especially medical stuff. theres like 4 million foreign residents in japan and barely any hospitals have interpreters, so a lot of ppl just avoid the doctor or wing it with google translate.

now the very honest part:

• its VERY vibe coded. its an mvp held together with hopes and dreams. solo 18yo, no funding.
• i have exactly 1 actually-verified clinic. the rest are clinics that publicly say they accept english patients, aggregated into one place.
• the real booking system + clinic dashboard is the dream if this actually goes anywhere.
• money plan is clinics pay a flat listing fee, free for patients. no idea if clinics would actually pay tho.

so what im actually asking:

1. is this a real problem, or do ppl just cope and it doesnt matter enough to use a tool for it?
2. would u use this, or know someone who would?
3. is the clinics-pay model dumb or does it make sense?
4. keep building or is it a nothing burger? be honest.

i even asked some target users directly and got a total mix, some were "yes pls" and others were "just learn japanese lol." so idk. roast the idea, roast the vibe coding, all of it.

I came across an interesting idea recently: when you tap your desk, the sound travels through the surface into your laptop's chassis — and taps in different spots actually sound measurably different to the built-in microphone (different distance, damping, resonance). Which means, in theory, you could tap the desk to the left of your laptop to trigger one action, and to the right for another. No extra hardware, just software listening to the mic.

So imagine four invisible "buttons" on the desk around your laptop:

• Tap left-rear → your email opens
• Tap right-front → screenshot to clipboard
• Tap right-rear → play/pause music
• Tap left-front → run a script / open a folder

You'd calibrate it once by tapping each spot ~10 times so it learns how your desk sounds, and there'd have to be filtering so typing, talking, or putting a mug down doesn't trigger anything.

Some honest caveats I can already see: it would only work well on rigid desks (solid wood, laminate — probably not glass or hollow doors), you'd need to recalibrate if you move the laptop, and it could never be 100% misfire-proof, so you'd probably not want "send email" on it — more like safe, repeatable actions.

What I'm curious about:

• Would you actually use something like this day-to-day, or is it a gimmick that gets old in a week?
• What actions would genuinely be worth a desk tap for you? (Things your hands do 20× a day)
• Would you trust it enough to leave it always listening, if all audio is processed locally and discarded?
• How much would misfires kill it for you — is 95% accuracy usable or annoying?

If I end up going down this rabbit hole, I'll share whatever comes out of it.

hello everyone,

I have an app idea centered around helping people find businesses, places, services, and activities that align with a certain value system.

What I’m struggling with is not the concept, but the right format for the product.

I want it to feel simple, clean, intuitive, community powered, but still highly controlled in terms of quality.

I don’t want a fully open platform where anyone can post anything and it goes live instantly. I want users to be able to contribute and help grow the platform, but in a way that keeps the library curated, trustworthy, and organized.

So what kind of contribution/moderation system would work best so it stays useful without becoming chaotic and keep quality to the maximum ?

Would also love any ideas on structure, UX, and what mistakes to avoid early.

And if you know any apps or websites with a similar concept that I could use as inspiration, I’d love to hear about them

Thank you very much

I found this image on pinterest and it inspired me to possibly make an app that does exactly this. I find myself constantly writing things and then copy and pasting weak words into google, searching for stronger synonyms. So what if instead of doing that you just copy and pasted everything into this app and words would be picked automatically to swap out with stronger words.

For example:

• important → crucial, essential, vital
• good results → promising results, strong results, compelling results
• In conclusion → To conclude, Ultimately, In summary

Everything would run entirely on device, local, private, offline. I'd probably use local token classification or cross encoder models that are extremely small and optimized. Obviously I would be building this for myself, but I'm just making this post to ask if you would think other people would pay like $5 for something like this? That way I can optimize for making it public before I even begin developing it. Let me know what yall think!

Ideation is a skill and you get better at it as you do it more. I’ve been at it for about 10 years now. I used to try to get others to build my ideas, but I taught myself app development and I’m able to do it now

Long story short, I have too many projects which are about 50-80% finished and I’m looking for someone, or multiple people, to help me keep on track and help in any way they want.

I see the trash that’s making money on the App Store and I guarantee at least one of my projects will make a killing

Send me a DM if you’re interested

I’m exploring an idea and want honest feedback before building anything.
Imagine a small wearable device (pendant/glasses style) that you can wear throughout the day.
The concept:
It continuously understands your surroundings using camera + microphone.
It does not store hours of raw video/audio.
Instead, it converts experiences into meaningful memories (people met, things seen, tasks discussed, important moments).
When you press a button and ask something like:
“Where did I keep my keys?”
“What did we discuss yesterday?”
“Who was that person I met at the event?”
It searches your personal memory and answers.

The main difference from current AI assistants:
Privacy-first.
Local processing as much as possible.
Your data stays on your device.
The device is not meant to record everything like a camera; it is meant to build a useful personal memory.
Questions:
Would you actually wear something like this daily?
What would be your biggest concern: privacy, battery, accuracy, or something else?
What is the one feature that would make you pay for such a device?
Would you prefer a camera-based wearable or an audio-only memory assistant?
I’m not selling anything yet — just trying to understand if this solves a real problem.
