Features

Everything you need to run AI agents

Computer Use

Give any agent hands on your desktop using native Accessibility APIs — no vision model required. Click, type, scroll, open apps, and control Chrome via CDP.

Multi-Tab Workspace

Open unlimited agent tabs simultaneously, drag to reorder, and set per-tab working directories. Tabs and sessions are fully restored on restart.

Cross-Agent Analytics

Track token usage and estimated costs across every agent and session. Daily chart, model breakdown, and agent breakdown — all stored locally.

9 AI Agent Adapters

First-class support for Claude Code, Codex CLI, GitHub Copilot CLI, Gemini CLI, OpenCode, Pi, Qwen-Code, Crush, and Hermes — each with auto-detect and install.

CoWorker Personas

Inject specialist role system prompts into any agent tab instantly. Built-in roles, online presets (Karpathy, Devin-style, Analyst), or your own custom text.

28-Provider Settings

Configure DeepSeek, OpenAI, Anthropic, Gemini, xAI, Groq, Ollama, LM Studio, OpenRouter, and 18 more — with local inference auto-discovery.

Unified History

Every conversation across all agents is captured and indexed. Search by content or agent, and restore any past session including its working directory.

Cron Scheduler

Schedule automated agent tasks with Interval, At Time, or Custom cron modes. Human-readable preview and run-count dashboard included.

Cross-Platform

Runs natively on macOS (arm64 + x64), Windows x64, and Linux x64. Full PTY terminal with xterm.js, correct resize handling, and native menus.
