Turn your docs into a 24/7 AI agent
Upload PDFs, Word docs, or any text. ChatStack builds a production-ready AI chatbot trained on your content — deployed to your site in under 2 minutes.
From zero to deployed in 3 steps
No ML expertise. No infrastructure. No DevOps. Just your documents and a few clicks.
Upload your documents
Drop in PDFs, Word docs, Markdown files, or plain text. Our pipeline chunks, embeds, and indexes everything automatically.
Configure your chatbot
Pick a preset (support, sales, education…), set the tone, colours, and welcome message. Takes two minutes.
Deploy anywhere
Embed on any website, connect to Shopify, or share a public link. Your bot is live in seconds.
Everything you need, nothing you don't
ChatStack uses the same RAG techniques that power enterprise AI products — at a price that makes sense for small teams.
Advanced RAG pipeline
Hybrid BM25 + vector search, cross-encoder reranking, and MMR diversity — not basic vector similarity.
Built-in tools
Give your bot superpowers: web search, Wikipedia, Gmail, Slack, GitHub, Jira — no code required.
Shopify integration
One click to embed a fully branded chat widget on your Shopify storefront. Convert browsers into buyers.
Enterprise-grade security
Fernet-encrypted API keys, JWT with refresh rotation, rate limiting, audit logs, and CSP headers out of the box.
Real-time streaming
Answers stream word-by-word over WebSocket. Users see responses instantly, not after a 5-second wait.
9 chatbot presets
Support, sales, legal, healthcare, education, e-commerce — each with tuned prompts and temperature defaults.
