I work in a manufacturing/warehouse environment and we receive batches of scanned packing slips as single massive PDFs. Nobody on the teams splits these and that’s why I want to automate it.

The problem:

\- PDFs are fully scanned — no embedded text, all image-based

\- Pages are landscape-rotated 90°

\- Each "document" inside the batch belongs to a specific 8-digit PO number (e.g. 20289562)

\- Some pages have no PO number at all (cover sheets, continuation pages)

\- Occasionally the same PO spans multiple consecutive pages

What I'm trying to build:

\- Script reads a folder of PDFs

\- OCRs each page and detects the PO number

\- Groups consecutive pages that share the same PO into one output PDF

\- Pages with no PO detected get flagged separately for manual review — not silently attached to another PO

\- A second script lets a human approve or reject each output file before it gets moved to the final folder

Questions:

\- What's the best way to handle rotation detection before OCR? I was thinking Tesseract OSD but open to other approaches

\- How would you handle pages with no PO — attach to the previous group, flag as unknown, or something else?

\- Any tips on making the OCR results consistent between runs? Right now borderline scans feel non-deterministic

\- Is PyMuPDF + pytesseract the right stack for this or is there something better for scanned documents?

Not a professional developer — just trying to automate something that's eating up hours of manual work every week. Any advice appreciated.

Sto costruendo DStudio, un'app desktop open-source incentrata su DeepSeek V4. DeepSeek rimane il principale modello di ragionamento e gestisce la conversazione, mentre modelli locali più piccoli si occupano di compiti specializzati:

\- Qwen2.5-VL legge immagini
\- Qwen Image genera ed edita immagini
\- Qwen3 Embedding cerca documenti semanticamente
\- Poppler estrae testo e informazioni sulle pagine dai PDF

Questo ecosistema esiste perché DeepSeek V4 è eccellente per il ragionamento e il contesto lungo, ma caricare ogni capacità multimodale all'interno dello stesso grande modello sarebbe inefficiente. DStudio instrada i compiti ai modelli specializzati e poi restituisce i loro risultati a DeepSeek per la risposta finale.

Ho recentemente aggiunto il recupero di PDF lunghi. DeepSeek decide se creare un'anteprima, leggere una pagina fisica esatta o cercare l'intero documento. Per la ricerca semantica, DStudio crea e memorizza una rappresentazione per pagina, recupera le sei pagine più rilevanti e invia solo quelle a DeepSeek.

Su un PDF di prova di 1.000 pagine, ha trovato un passaggio collocato a pagina 777 da una domanda parafrasata. L'indicizzazione iniziale ha impiegato circa 25 secondi; le ricerche successive hanno impiegato circa 0,23 secondi.

Sto cercando feedback: il recupero dovrebbe usare rappresentazioni di pagina o blocchi sovrapposti? Dovrei aggiungere BM25 o un miglioratore di classifiche? E come supporteresti in modo efficiente libri scansionati di 1.000 pagine?

Hey everyone,

We’ve built and launched Docpose.cloud, an online platform for file conversion, document processing, OCR, PDF tools, archive extraction/compression, and email file handling.

The platform is already live and being used by many monthly free users, paid subscribers, and businesses. Our API is also integrated with more than 10 external systems and business workflows.

Docpose.cloud supports tools for:

• Document and file conversion
• PDF conversion and processing
• OCR for scanned documents and images
• Archive extraction and compression
• Email file formats like EML, MBOX, PST, OST, and related formats
• Batch processing
• API-based file conversion workflows

We built it because many online file tools are either too limited, overloaded with ads, require unnecessary sign-ups, or do not offer reliable API access for businesses.

Our goal is to make file conversion and document processing simple for individual users, while also providing scalable API access for companies that need automated file workflows.

I’d love to get feedback from people who use file converters, OCR tools, PDF tools, or email archive tools regularly.

What feature would you expect from a platform like this?
And what problems have you faced with existing online file conversion tools?

Most document extraction tools rely on templates. I wanted something that could handle invoices, receipts, bank statements, and other PDFs without vendor-specific rules.

I built Super Parser. You define the schema once, then forward or upload documents. It extracts structured data and pushes it to Google Sheets, Zapier, Make, or your own API.

I'm validating the product now. I'd appreciate feedback from anyone dealing with document-heavy workflows:

Is this a problem you still face?

What would stop you from adopting a tool like this?

Hi All,

I am QE by profession. made a doc control app for myself.

I made this android app for myself. As my file explorer gets dumped with everything and anything. I wanted to have folders, revise docs(Taxes, insurances, license, etc). with OCR you can search for a word and every document with that word would pop up. you can set expiration date to docs.
please dm and drop a comment if you would like to test my app. you will get lifetime free without ads for this.

thank you.

A desktop app (Mac/Windows) for grading paper multiple-choice exams — built by an instructor, for instructors.

How it works 

  1. Print your own answer sheets on a normal printer (no proprietary Scantron forms).

  2. Give the exam — students bubble in answers, pen or pencil.

  3. Scan the whole class to a single PDF (copier/scanner), or snap photos.

  4. Upload the PDF + your class roster; it grades the batch and exports to a spreadsheet.

  What makes it different

  - Local & private: everything runs on your computer — rosters, scans, and results never leave your machine (FERPA-friendly). No student data in anyone's cloud.

  - Handles real-world sheets: reads pen, pencil, colored ink, erasures, and crossed-out/changed answers (it reads the correction instead of flagging two marks wrong).

  - Multiple versions: run several versions of a test, and pre-print the version so students can't forget to bubble it.

  - Per-question item analysis: see which questions got missed most.

  - Review before export: check any uncertain ID matches before grades go out.

  - Annotated sheets: hand back a marked sheet (right/wrong) so students can review — no sneaking a pencil back in to claim an error.

  Who it's for 

  Instructors who give paper multiple-choice exams — especially large sections — and want grading that's fast, accurate, and keeps student data on their own computer.

  Try it    

  - See it in action: scantograde.com

  - Want to test it on a quiz? Comment here or DM me and I'll set you up with a trial.

  Questions about whether it fits your workflow? Ask below — happy to talk specifics.

I've been working on this for the past few weeks, planning to launch it in the next few days.

Still need some minor improvements here & there, but the core product is working perfectly

We built Nebula to convert complex PDFs and scans into structured Markdown for AI, RAG and document-automation workflows.

Unlike basic text extraction, it aims to preserve the meaning encoded in tables, charts, reading order and page layout. In our benchmark on complex business documents, Nebula outperformed Mistral OCR by 20.8 points and Azure Document Intelligence by 6.2 points on semantic meaning recovery.

We’d like this community to stress-test it with the hardest documents you’re authorized to use.

You can run four free conversions without creating an account:

https://nebula.ur-ai.net/

An account is only required to download and retain the Markdown. Use community code NEBULA-10 for additional credits. An API is also available - DM me if you’d like to test it.

What I’d most like to know:

• What information needed to survive?
• What did Nebula preserve well?
• What did it miss or structure incorrectly?

You can DM me or submit feedback inside Nebula. Specific examples and expected outputs are especially helpful.

Full disclosure: I’m one of the founders. We don’t use uploaded documents or outputs to train our models. Please only upload files you’re authorized to use.

I've been working on an open‑source Android library for automated data extraction from printed forms, and I wanted to share it with this community.

OpenScanVision is an Android library that scans printed voting cards, surveys, and bubble sheets – extracting structured data (filled bubbles and QR codes) entirely offline.

How It Fits into Document Automation

• Input: Physical forms (voting cards, surveys, bubble sheets) captured via camera.
• Processing:
  • Detects 4 ArUco markers (IDs 0–3) with Kalman filtering for real‑time tracking.
  • Computes homography and warps the card to a canonical template.
  • Decodes QR codes from the original frame (preserves sharpness for ML Kit).
  • Extracts filled bubbles using weighted disk sampling + z‑score classification.
• Output: Structured data (filled bubble indices, QR payload, confidence score) that can feed into your document automation pipeline.

Tech Stack

• Kotlin
• OpenCV (contrib) for ArUco detection and homography
• Google ML Kit for QR decoding
• CameraX for frame acquisition
• Modular – core has zero UI dependencies

Use Cases

• Automated survey processing
• Form data extraction
• Election ballot scanning
• Any workflow where physical forms need to be digitised and structured

Performance

• Latency < 150 ms per frame on modern devices.
• Accuracy > 99% on well‑printed cards with good lighting.
• False positive rate < 0.5%.

Repository & Integration

The library is MIT‑licensed and available on JitPack. A full sample app (CameraX + Compose) is included.

GitHub: https://github.com/MatiwosKebede/openscanvision

Would love to hear feedback from anyone working on similar document automation challenges – especially around form processing, OCR alternatives, or integrating physical document scanning into automated workflows. 🙌

Hoping there may be some AI experts here who can point me in the right direction.

I currently work with technical drawings/plans that contain various symbols, labels, and device types. The challenge is that these symbols and labels can vary significantly from one plan set to another.

Our current process is largely manual:

• Review the plan and identify specific symbols/devices.
• Place sequential labels on the drawing (#1, #2, #3, etc.).
• Create an Excel spreadsheet containing those labels.
• Extract additional information from the plans such as room names, device descriptions, locations, and other relevant data.
• Manually link all of this information back to the labelled plan.

What I'm trying to determine is whether there is an AI-based solution that could streamline or automate this workflow.

Ideally, I would like to be able to:

1. Upload a PDF plan or drawing.
2. Define a set of symbols, labels, or devices to look for (which may be different for each project).
3. Have the AI scan the plan and identify all matching symbols.
4. Automatically place sequential tags/labels onto the drawing.
5. Extract related information from the plan, such as room names, device types, notes, coordinates, or other nearby text.
6. Generate an Excel spreadsheet containing all identified items and associated data.
7. Optionally export the marked-up plan with the generated labels visible.

For context, these are typically lighting, electrical, emergency lighting, and services-related plans, so the solution would need to work with PDF drawings containing both symbols and text.

I'm interested to know:

• Are there existing AI/OCR/CAD tools that can already do this?
• Has anyone successfully implemented a workflow like this?
• Would this require a custom AI model, or could it be achieved using existing tools such as Azure AI Document Intelligence, OpenAI Vision, Bluebeam, AutoCAD plugins, Power Automate, or similar platforms?

Any advice or recommendations would be appreciated.

Thanks.

What it does: you give it a standard — a checklist, a compliance spec, a review playbook — plus the documents that are supposed to satisfy it. It tells you which requirements are actually evidenced in the docs and which aren’t, and every “this is missing” is checkable against the source text. The usual keyword-matching approach cries wolf about 70% of the time; this one got that to zero.

Tested clean on financial filings and a batch of contracts. The tech isn’t my problem — finding the buyer is. Everywhere I imagine it being useful (contract review, RFPs, diligence) already has funded competitors, or the pain isn’t big enough that anyone pays.

If you’ve done doc-heavy work: where does a *missed* or *falsely-flagged* item actually cost real money? Not “where could this be useful” — where’s it expensive enough that someone would pay to prevent it?

Built a Chrome extension that converts EML files to PDF, entirely locally, no server, no upload, files never leave your machine. Wanted something private for archiving emails without sending them anywhere.

It's still early, so there are probably rough edges. Would really appreciate any feedback, bugs, missing features, anything that would make it more useful for you.

AI tools discussion:

I work for a commercial flooring company. Four of us in the office, a few more on the tools and one guy offshore that we use to do our material take-offs.

We're doing commercial tendering constantly which involves trawling through sometimes hundreds of pages of architectural drawing, material schedules and specifications. Naturally, this takes up a massive amount of time just to compile the information that is relevant to us. Out of a set of drawings that could be 300 pages, we would only require the floor finishes plan, internal elevations, subfloor and detailing. That could be about 14 pages out of hundreds.

Is there a set of AI tools which we could use to comb through all of these documents and pull together only what we require?

Are there any potential legal ramifications with having AI scan through these documents? (for context, we are located in Victoria, Australia)

Are AI tools actually what I require, or should I be looking at another system?

Any suggestions would help a lot 🙏
