What you get
- **Visual editing of the agent's work.** WYSIWYG editors for markdown, mockups, Mermaid, Excalidraw, CSV, data models, and code in Monaco. You and the coding agent edit the same files.
- **Red/green diff review.** Step through the agent's proposed edits in the rendered document and accept or reject each one.
- **Parallel agent sessions.** Run several coding agents at once, each isolated in its own git worktree.
- **Session kanban.** Track every session on a board. Search, resume, and link sessions to the files they touched.
- **Task tracking.** Plans, bugs, features, and todos in trackers your agents read and update alongside you.
- **Heterogeneous agents.** Codex and Claude Code side by side, plus OpenCode and GitHub Copilot in alpha and a Gemini provider.
- **Git built in.** Branch and worktree management, staging, AI-drafted commits, and an embedded terminal.
- **MCP client and servers.** Connect any MCP server, with tool results rendered as visual widgets rather than raw JSON.
- **Extension SDK.** Every editor, including the built-in ones, goes through the same EditorHost contract, so an editor you build is first-class. Ask your agent to build one for a file type we do not ship.
- **Plain files on disk.** Content and status in markdown, workflows in slash commands, everything in your git repo. No proprietary store to migrate out of.
- **iOS companion.** See which agents need you, reply by text or voice, swipe through diffs, queue the next task, and get a push when an agent is waiting.
