I recently Open-Sourced Document Chat — a completely free, open-source platform that lets you upload documents and have intelligent AI conversations with them. Built with Next.js 15, powered by multiple AI providers, and ready to deploy in minutes.

Test it out: https://document-chat-system.vercel.app

GitHub: https://github.com/watat83/document-chat-system

The Problem We’re drowning in documents. PDFs, Word files, research papers, contracts, manuals, reports — they pile up faster than we can read them. And when we need specific information? We spend hours searching, skimming, and hoping we haven’t missed something important.

AI assistants like ChatGPT have shown us a better way — natural language conversations. But there’s a catch: they don’t know about YOUR documents. Sure, you can copy-paste snippets, but that’s manual, tedious, and limited by context windows.
