Jean

Jean is a dev environment built specifically for AI-assisted coding. Instead of running one agent in one terminal, it lets you spin up multiple agents in parallel, each in its own isolated Git worktree, so they can work on separate branches simultaneously without stepping on each other.

It's opinionated by design. Jean makes decisions about how AI-assisted development should work, so you don't spend time configuring workflows from scratch. Git worktrees, chat sessions, terminals, GitHub and Linear integrations all live in one interface.

Key capabilities:

• Isolated workspaces – every agent task gets its own worktree. Launch multiple agents at once, review each workspace independently, and merge only what you approve.
• Linked Projects – connect related repos (app, API, docs, SDK) so agents share context across all of them without manual copy-pasting.
• Magic Git Commands – load GitHub or Linear issues into a session, run AI code reviews, generate commit messages and PR descriptions, write release notes, and resolve merge conflicts from a command palette.
• Magic Prompts – every built-in workflow has an editable prompt template. You can swap models and reasoning levels per workflow, using faster models for routine tasks and stronger ones for reviews.
• Mr. Robot – polls open GitHub issues, creates a worktree per issue, and drafts a focused plan. Can execute approved plans automatically on a schedule.
• Token-reduction plugins – RTK compresses CLI tool output by 60-90%; Caveman trims Claude's replies by 65-75%. Both install with one click.
• Remote access – run Jean on a Linux server and connect from any browser or the native app. Works well over Tailscale for private network access.

Jean supports OpenCode, Claude CLI, Codex CLI, Cursor, Grok, Kimi Code, and others. You bring your own subscription for each provider. It's a solid alternative to tools like Claude Code or Jules when you need multi-agent coordination and cross-repo context in one place.
