Document chatbot boilerplate with a Vercel button

What it does ChatFiles is a Next.js web app that lets you upload documents and ask questions about them via GPT-3.5. It chunks uploads into embeddings, stores them in a Supabase vector database, and surfaces answers through a chat interface built on Chatbot-UI. Under the hood, it is mostly plumbing: LangChainJS orchestrates the retrieval chain, Supabase hosts the vectors, and OpenAI handles the generation.

The interesting bit The project’s main convenience is the Vercel deploy button and a pre-drawn architecture diagram—essentially a starter kit for the “chat with your files” genre. It does not pretend to reinvent the stack; it simply wires familiar pieces together so you can get a working demo without writing boilerplate.

Key highlights

• Built on Chatbot-UI, LangChainJS, and Supabase pgvector
• One-click Vercel deployment with environment variable templates
• Supports GPT-3.5 conversations with uploaded documents
• TypeScript / Next.js / Tailwind stack
• Architecture diagram included in the docs

Caveats

• Feature list is minimal: only GPT-3.5 is explicitly supported, with no mention of GPT-4 or other LLMs
• Requires external Supabase vector database setup and several environment variables before it runs
• README is thin on technical details beyond deployment steps

Verdict Good for developers who want a quick RAG prototype over documents without assembling the stack themselves. Skip it if you need models beyond GPT-3.5 or extensive backend documentation.
