Use tool ↗About PDFtoChat
PDFtoChat lets you upload a PDF, textbook, or contract and ask it questions instead of reading the whole document. It's an open-source demo project on GitHub maintained by developer Hassan El Mghari (known online as Nutlope), built with Next.js, the Mixtral model via Together AI, Chroma for vector search, and LangChain for retrieval. There's no company behind it and no paid tier; it runs as a free, MIT-licensed web app sponsored by Together AI, Bytescale, Chroma, and Clerk. The repository shows active commit history and open issues, so it's maintained as a side project rather than a product with a dedicated support team.

Pros & cons of PDFtoChat
PDFtoChat does the single job of PDF question-answering competently and costs nothing, which makes it a reasonable pick for occasional use. It's a side project rather than a maintained product, so don't expect customer support, uptime guarantees, or new features on any schedule.
Pros
- Free with no account limits mentioned
- Open-source, so the retrieval pipeline is inspectable
- Backed by real infrastructure sponsors (Together AI, Chroma) rather than an ad-hoc demo
- Handles textbook and contract-length PDFs, not just short files
Cons
- No company or support channel behind it, just an individual maintainer
- As a side project, features and uptime aren't guaranteed long-term
Best for
- Occasional PDF Q&A without paying for a subscription
- Developers curious about the underlying RAG stack, since the code is public
Not for
- Teams needing an SLA, support, or guaranteed uptime
- Anyone with sensitive documents who wants clear data-handling commitments from a company
