PDFPeer
A competent developer can build a useful, self-hosted PDF-chat replacement in about a week with modest monthly API and maintenance costs; there are no vendor-provided durable moats evident on the product pages.

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 PDFPeer alternatives, with the arithmetic →
What a replacement has to do
- Upload PDF → extract text/OCR → split into chunks and embed → store embeddings in a vector DB → retrieve context and call LLM to answer user chat queries
What it still won’t have
- Priority/support responsiveness from vendor
- Hosted, fully managed infrastructure and scaling
- Any undocumented internal optimizations or moderation/billing features
- Proprietary UI polish and built-in lifetime deal
What remains hard
- Product polish and ongoing maintenance

Runnable build prompt
Build a single-tenant PDF QA web app using Next.js (React) for the frontend, Node.js/Express for the API, Postgres for metadata, S3-compatible storage for PDFs, Apache Tika + Tesseract for extraction/OCR, a vector DB (e.g., Pinecone or Milvus) for embeddings, and OpenAI-compatible APIs for embeddings and chat. Core features in scope: PDF upload with size/page limits, text extraction and OCR, chunking and embedding ingestion, vector search, chat UI that submits questions and displays streamed LLM responses, basic user sign-in (email only), and admin UI to view uploaded PDFs. Out of scope: multi-tenant billing, enterprise SSO, advanced analytics, mobile apps, and a polished marketing site. Include error handling for upload failures, extraction/OCR fallbacks, rate limits, retries for API calls, and tests for extraction, ingestion, and the chat endpoint. Document deployment steps and a minimal Docker Compose for local testing.

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.
