Meet Theo
Your autonomous AI software engineering teammate — it explores your codebase, proposes a plan, and edits real code across the whole solution.
Windows desktop app · self-hostable service for Windows, Linux & macOS.
An expert engineer at your service
Explores your codebase, proposes a plan, then implements it across the whole solution — writing code that matches your architecture and conventions.
Gemini Live voice & vision
Real-time, interruptible voice conversations backed by Google Gemini Live — share your desktop screen, application windows, or camera while Theo works alongside you.
Deep .NET & TypeScript superpowers
Semantic refactoring with Roslyn, TypeScript & ESLint diagnostics, assembly decompilation, and post-mortem crash & memory-leak analysis of process dumps.
Works like a team
Spawns specialized sub-agents that run in parallel, and keeps a persistent memory — a knowledge graph plus recall across every past conversation.
Multi-model by design
First-class support for Google Gemini & Vertex AI, Anthropic Claude, OpenAI, and open-weight models via OpenRouter — swap models freely as the landscape shifts.
Self-hosted & computer use
Runs on your own infrastructure with Entra ID SSO, drives a real browser with Playwright (desktop & mobile emulation), and operates live desktop windows.
