500+

Works with your tools

Pull website content, docs, public links, and approved files into a compact demo brain before the first voice turn.

How it works

Agents show your product in realtime. They navigate and talk.

Lives in your product

The browser session opens the real site surface and keeps all actions inside a scoped sandbox.

Interactive by default

The agent answers questions, moves the cursor, clicks, and highlights what it is explaining.

Context recovery

A saved snapshot lets the call continue after a user changes topic or interrupts the answer.

Single-VM alpha

Docker Compose runs app, Postgres, browser pool, and Yandex voice bridge together.

Production alpha

Start with one website and a live Yandex voice agent.

Build a sandbox

No account layer in v1. Keep access private at the VM/network boundary while the core call workflow is validated.

Yandex Realtime API for speech, model, VAD, and tool calls.

Pooled sandbox browsers reset after every demo session.

Generated scripts and AGENTS.md stay tied to the crawled website context.
