Any business gets a deployable RAG chatbot in under 60 seconds

Self-Serve AI Assistant Builder

Small businesses priced out of every chatbot vendor on the market.

The Problem

Most chatbot vendors charge $99-$499/month, lock answers to a generic FAQ, and need a developer to install. Small businesses skipped the whole category.

The Outcome

Built an end-to-end builder that crawls a site, vectorizes the content into pgvector, and hands back a single <script> tag the owner pastes into their body. Visitor chat is grounded in their real pages via RAG, with daily caps and per-IP rate limits keeping the bill at $0/mo on free tiers.

How It Works

BFS crawler captures up to 15 pages, chunks + embeds inline
RAG retrieval against pgvector top-5 cosine search
Provider chain: Gemini -> Groq -> OpenAI keeps free tiers absorbing traffic
Domain-pinned widget with /key admin command -- no login required
