Documents and notes decision
ReadFast
A single technical user can build a usable document-to-insight workflow (upload, OCR/layout extraction, LLM-driven summaries) quickly, but reproducing the product's offline/local mobile app, multi-model bundling, and polished UX would require more work or different tradeoffs.

Open-source builds that already do this
Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need - the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship. All ReadFast alternatives, with the arithmetic →
What a replacement has to do
- Upload PDF → extract text/layout/tables (OCR if needed) → run LLM prompts to extract summary, risks, and actions → render results in a simple web UI
What it still won’t have
- Offline & Private (files stay on device) as advertised
- Mobile app(s) and polished cross-platform UI (the site advertises a download app / Flutter)
- Multi-model bundled integrations and model choice (OpenAI, Gemini, Claude, Mistral listed)
- Priority support and polished product UX
What remains hard
- Product polish and ongoing maintenance

What we assumed
The verdict above measures whether you could build it. This one is only about money.
Runnable build prompt
Build a lightweight web app (Python Flask backend, React frontend) containerized with Docker that lets one user upload PDFs and get extracted, LLM-generated decision-ready summaries. Stack: Flask, Celery+Redis for background jobs, PostgreSQL (or SQLite) for metadata, PyMuPDF for text extraction, Tesseract for OCR fallback, layout-parser or tabular heuristics for simple table extraction, and OpenAI API for summarization. Core features: file upload endpoint, text + layout extraction pipeline, prompt templates for summary/risk/action extraction, background job status, simple authenticated single-user web UI showing results and downloadable JSON. Out of scope: native mobile apps, bundling multiple hosted LLM providers (beyond one provider), enterprise account management. Require error handling, retries, logging, and unit tests for extraction and API integration.

How the score was reached

- Price verified on pricing page+3
- 3/3 assessment runs agreed+4
- Evidence score67
The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time - so the same evidence always produces the same number.
