Genei
A capable developer can recreate the core summarisation, storage and QA features in about a week plus ongoing light maintenance; Genei's main durable advantage is brand recognition rather than proprietary technical barriers.

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 Genei alternatives, with the arithmetic →
What a replacement has to do
- Ingest PDFs/webpages, extract text, call an LLM to produce summaries/keywords, store documents & summaries, provide search and question-answering over documents.
What it still won’t have
- Priority server access / SLA
- Polished UX and walkthroughs
- Any proprietary models or vendor optimizations
- Integrated chrome extension and cross-device polish
What remains hard
- Brand trust
Genei is part of Y-Combinator, a US startup accelerator with over 2000 companies including Stripe, Airbnb, Reddit and Twitch.

What we assumed
The verdict above measures whether you could build it. This one is only about money.
Runnable build prompt
Build a minimal self-hosted Genei-like app using FastAPI (Python), Postgres, React, and FAISS. In scope: user file upload (PDF/URL), robust text extraction (pdfminer + Tesseract OCR fallback, HTML scraper), persist raw text and metadata to Postgres, generate embeddings and summarisation via OpenAI/other LLM API, implement vector search and a QA endpoint that composes context + LLM prompt, and a simple React UI to upload files, view stored docs and summaries, and ask questions. Out of scope: multi-tenant billing, analytics dashboard, browser extension, and enterprise SLAs. Include error handling, retries for API calls, basic unit tests for extraction and API endpoints, and a README with deployment steps (Docker Compose).

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.
