Platform

The whole product, in your agent's hands

Models, knowledge, analytics and the widget. Every one of them is a call it can already make.

Haiku

It picks the model for you

GPT-5.2, Claude and Gemini for the hard questions. Grok and Haiku when speed matters more. Your agent chooses, and you can overrule it later.

See what it could not answer

Every conversation scored for sentiment, every unanswered question surfaced. Close the gap once and it stops coming back.

It reads what you already wrote

Your site, your PDFs, Word, PowerPoint, Excel, Notion. It crawls and uploads them itself. Nobody has to prepare a thing first.

It ships the widget itself

Your agent already has your repo open, so it writes the embed tags straight into your site. Nothing to copy, nothing to paste. The widget is just live, styled to match your brand.

Anything the dashboard does, your agent does

Every screen in the product is a REST endpoint and an MCP tool underneath, so a coding agent is never stuck asking you to go and click something.

How it works

One prompt, four steps, none of them yours

What your coding agent does after you hand it the prompt, and the one step it leaves you.
