What is Tanzanite

Tanzanite is an AI agent platform. It lets you run autonomous agents that plan, call tools, write and edit files, execute code, and complete multi-step work on your behalf — from a native app on macOS (with iOS and Android in progress).

How it fits together

Section titled “How it fits together”

Agents run in the cloud and act on your machine through a secure bridge:

  • The app is where you work — create projects, talk to agents, review and approve their actions, and watch plans run in real time.
  • Agents run in the cloud and stream their reasoning, tool calls, and results back to you live.
  • Tool calls reach your machine through a WebSocket bridge, so an agent can read and write files in a project folder, run commands, and use local capabilities — only with your approval.
  • A harness governs every agent. The harness defines the system prompt, which tools are available, how models are routed, and the safety guardrails. It can be swapped without redeploying anything.

What you can do

Section titled “What you can do”

Out of the box, Tanzanite supports:

  • Projects — cloud or local working contexts an agent operates in.
  • Chat & agents — direct conversation plus long-running autonomous plans that can spawn subagents for parallel work.
  • Workflows & schedules — multi-step automations and recurring runs.
  • Apps — build small local-first apps that run inside Tanzanite and use the window.tanzanite runtime (file access, peer sync, on-device AI).
  • Code execution — run code in sandboxes (Piston, Pyodide, isolated-vm).
  • File, image, video, and voice — upload media, generate it, and dictate.
