What PDFtoChat is
PDFtoChat is a web app for asking questions about PDFs, including papers, textbooks, and contracts. To use it, create an account, upload a PDF for AI analysis, and then ask questions about its contents. The free plan costs nothing and requires a free account. Access is listed for web and self-hosted use, and the project’s source code is available on GitHub to read, review, or contribute to.
The project README describes a Next.js app that uses Mixtral through Together AI for language-model inference. LangChain.js and Chroma Cloud support document retrieval; Chroma Cloud uses hybrid dense and sparse vector search with Qwen and SPLADE embeddings. The listed components also include Bytescale for PDF storage, Clerk for authentication, and Vercel for hosting and Postgres, with Neon as an alternative database for self-deployment. The template can be deployed to Vercel or another host after configuring its service credentials. The README identifies PDF image support and sign-in checks for chat API routes as future work.
