Everything you need.

Opinionated by design. We picked the best workflows so you can focus on shipping.

Isolated Workspaces

Run multiple AI agents in parallel, each in its own isolated git worktree. No conflicts, no interference, maximum throughput.

Magic Git Commands

Investigate issues and PRs, review code with finding tracking, generate AI commit messages, PR descriptions, and release notes, and resolve merge conflicts — all with AI assistance.

Magic Prompts

Customize the prompt template, backend, model, and reasoning level behind every built-in workflow. Use a light model for commits, a heavy one for reviews — no UI churn.

Worktree Management

Automated worktree creation, archiving, and restoration. Manage branches and workspaces without touching the command line.

Automated Merging

Merge GitHub PRs or local worktrees automatically. Built-in merge conflict resolution powered by AI.

Token-Reduction Plugins

One-click installs in the Opinionated pane. RTK proxies your CLI tools to cut 60–90% of tool-output tokens across every backend; Caveman trims Claude's replies by ~65–75% with terse, technical output.

Mobile Access

Open Source

Free forever under the Apache 2.0 license. Inspect the code, contribute, and make it your own.

Opinionated by Design

No endless configuration. Jean has strong opinions about git workflows, workspace isolation, and AI orchestration — so you spend less time configuring and more time shipping.

Linear Integration

Investigate Linear issues, load context into sessions, and configure per-project API keys and team settings. Your Linear workflow, built in.

Multi-project & Linked Projects

Manage multiple repos from one dashboard. Link related projects and Jean auto-injects their CLAUDE.md, AGENTS.md, and docs/ into every session — cross-repo context without copy-paste.
