How it works
Three steps to your AI agent
Why it works
Built for teams that can't afford
wrong answers.
Precise, on-brand AI that stays within your content — without any complexity.
Your docs don't live in one place — that's fine
Websites, PDFs, DOCX, Notion, Confluence, plain text — all pulled together into one agent that knows everything.
Answers stay in-bounds. Always.
The agent only answers from your content. No guessing, no hallucinations, no off-brand responses — ever.
Meets your users where they already are
Website widget, shared link, Slack, or API. One click to go live — no migration, no new tools for your team.
Know what your team keeps asking about
Automatic summaries, sentiment scores, and lead identification out of the box — so you can fix the gaps in your docs.
Sounds like you, not like a chatbot
Set your tone, match your brand colors and logo, support multiple languages — so it feels like a natural part of your product.
Plug it into what you already built
Full REST API — programmatic control over chat, projects, documents, and conversations. No lock-in.

team already works.
