I built Code Reasoner because I got tired of being at the mercy of one AI model. Here's where it's at now.
Some of you saw my earlier post about Code Reasoner. (https://www.reddit.com/r/aiagents/comments/1ugvytv/introducing_code_reasoner_the_new_lookmood_ai/) This is an update on what it's become — but first, honestly, why it exists at all, because that's the part that actually explains the design.
A while back, a model capability I'd come to lean on got pulled out from under me. Overnight. And it stung more than I expected — not just the inconvenience, but the realization of how exposed I was. I'd built my whole workflow around trusting one model's judgment, and when it vanished I had nothing.
I'm a solo founder. No engineering team to bounce a gnarly bug off of at midnight. Just me, the problem, and whatever AI I could point at it. And the thing that kept burning me wasn't lack of help — it was confident help that was wrong. A single model would hand me a clean, authoritative-sounding fix, I'd ship it, and the bug would come back a week later because the model had glossed over the real cause. When you're alone, you don't have a second person to say "wait, that's not it."
So I stopped trying to find a better single model. I built the second opinion into the tool itself.
That's what Code Reasoner is: not one model you have to trust, but a council of frontier models that reason over your problem from different angles and check each other. One looks at whether your actual intent is being addressed. One runs adversarial verification against every constraint. One hunts for the logical gaps and regressions the others missed. Then a meta-reasoning layer weighs the conflicts and writes the verdict. No single point of failure. No single model's overconfidence going unchallenged — because another model is there to catch it.
Here's what it does now, and what changed since the last post:
It investigates instead of dead-ending. Describe your problem in plain words → it generates a discovery prompt you run in your editor (Cursor, Windsurf, VS Code, Claude Code, whatever you use) → you paste the report back → the council reasons over it. But now, if it doesn't have enough, it doesn't give up — it asks for the specific file it needs and tells you *why* ("send me your API client, I need to see whether the token refreshes on a 401"). It remembers everything across the whole investigation, and flags when a new file makes an earlier finding stale.
You can talk to it. Ask "why do you need that file?" or "what have you found so far?" mid-investigation and it answers from what it's actually gathered.
It won't fake confidence. This is the one I care about most, because it's the whole reason the tool exists. If the council agrees that what you gave it isn't usable — you pasted raw code instead of a diagnostic report, say — it refuses to invent a plausible-looking fix and tells you plainly what it needs. The thing that burned me is the thing it's built specifically not to do.
Then it hands you a surgical fix prompt — exact files, exact lines — that you run in your editor.
Who it's for: solo and technical founders who don't have a team. Devs who are done with generic AI advice that doesn't hold. Anyone on Cursor or Windsurf who's wanted a reasoning layer that thinks about the problem before the editor touches the code.
Honest about the limits: no fresh benchmark numbers from me — I'd rather you test it than trust my adjectives. And the biggest friction, which the last thread nailed, is still real: you're the one relaying text between the reasoner and your editor. Direct repo access so it reads your files itself is next on the roadmap. Not shipped yet. But it's the top of the list.
It's free. No signup, no card, no limit.

For the best experience, log in to LookMood AI and use it inside Mission Control — that's where the full investigation flow lives, with the conversation and file upload.
Throw your hardest problem at it and tell me where it breaks. I mean that — the last thread's criticism is literally what built this version.
