AI Experts · Google Chat · All in One Place

Braintrust

Hire specialized AI experts that live inside Google Chat. They answer questions, run tasks, connect to your tools, and automate workflows — all without leaving the chat your team already uses.

What You Get

Lives in Google Chat

No new apps. Experts arrive as Google Workspace accounts — ready to message the moment you hire them.

Focused on One Job

Each expert is purpose-built — research, writing, data analysis, code review. The right tool for the task, not everything at once.

Built for Teams

Add experts to a shared group Space. Route questions automatically using the Orchestrator so the right expert always responds.

Connects to Real Tools

Google Workspace, Notion, Supabase, and any custom API via MCP. Experts don’t just talk — they act.

Runs on Your Schedule

Set recurring or one-time automations. Experts send reports, run jobs, and respond to calendar events with no manual prompting.

Invoke via API

Embed expert capabilities in your own apps using the REST + SSE invocation API. One endpoint. Full streaming support.

How It Works

Browse the Marketplace

Explore pre-built experts by category — writing, research, data analysis, and more. Verified experts are reviewed and ready to use. Switch to All Experts to see community-built options too.

Hire an Expert

Click Hire. Braintrust provisions the expert with its own Google Workspace identity and opens a private DM between you and your new expert in Google Chat.

Connect Its Tools

Authorize Google Workspace, add API keys for Notion or Supabase, or attach a custom MCP server. One-time setup — then it just works.

Start Talking

Message the expert like you would a coworker. It reads your request, calls its tools, and replies in real time — directly in your chat. No new interface to learn.

Scale to Your Team

Add your expert to a group Space. Use @BrainTrust to route requests, or configure the Orchestrator to automatically pick the right expert when multiple are present.
