A dev environment for AI agents.

Works with

An opinionated AI agent workspace with strong opinions about how AI-assisted development should work. Git worktrees, chat sessions, terminals, and GitHub & Linear integrations in one cohesive workflow. Run it on your laptop or a dedicated server - connect from a browser or the native app.

Open source & free forever, backed by our philosophy.

Server · Web · Native

Run Jean on a server. Connect from anywhere.

Put Jean on a dedicated Linux host with jean-server, or turn on Web Access in the desktop app. The same workspace is available over the network - open it in a browser, or point the native Jean app at that remote instance and keep working with the full desktop shell.

  • Browser - full UI via token-protected HTTP/WebSocket (default port 3456).
  • Native app - title bar server icon → Add remote; switch Local ↔ remote anytime.
  • Tailscale recommended - private mesh access instead of exposing a public port.

Most useful features

The parts of Jean you'll use every day.

Linked Projects, Isolated Workspaces, Magic Git Commands, Magic Prompts, Mr. Robot, and server/web access are the high-leverage workflows that make Jean more than a chat window for agents.

Linked Projects

Make multiple repos feel like one knowledge base.

Link related projects once and Jean makes your AI agents aware of the surrounding codebase. Your app repo, docs repo, backend, SDK, and shared libraries can all contribute context to the same session - without copy-pasting files or rebuilding prompts by hand.

Shared agent context

Every linked repo stays visible to the AI

  • Agents are reminded to check linked repos for CLAUDE.md, AGENTS.md, and docs/.
  • Saved contexts from linked projects appear together, so prior decisions travel across repo boundaries.
  • Linked projects are available as shared context, so agents can understand and coordinate changes across related repos.

Agent Workflows

Parallel agents, magic commands, and automation.

Jean gives every agent a safe workspace, turns repetitive repo work into guided AI workflows, and can even sweep GitHub issues for you in beta.

Isolated Workspaces

Run agents in parallel without chaos.

Every task gets its own git worktree, so agents can investigate, edit, test, and propose changes independently while your main repo stays safe.

  • •Launch multiple agents at once without branch conflicts or file clobbering.
  • •Review each worktree separately before merging anything back.
  • •Archive, restore, or delete agent workspaces from Jean instead of juggling shell commands.

Magic Git Commands

Ship Git work without the busywork.

Investigate issues and PRs, run AI code reviews with tracked findings, generate commits and PR descriptions, write release notes, and resolve merge conflicts from one command palette.

  • •Load GitHub and Linear context directly into an agent session.
  • •Review diffs, track findings, and turn agent output into actionable fixes.
  • •Create commits, PR copy, release notes, and conflict resolutions with AI help.

Magic Prompts

Tune every workflow to your taste.

Every built-in workflow has an editable prompt template plus per-prompt backend, model, and reasoning controls. Use fast models for routine copy and stronger reasoning for reviews or investigations.

  • •Customize the exact instructions behind commits, reviews, PRs, and investigations.
  • •Choose different backends, models, and effort levels per workflow.
  • •Keep the UI stable while changing how the AI thinks and writes.

Mr. Robot

Beta

Let Jean sweep issues while you sleep.

Mr. Robot polls open GitHub issues, creates one Jean worktree per issue, and drafts a focused plan. If you want, it can yolo approved plans too.

  • •Schedule issue sweeps with limits for issue count and active worktrees.
  • •Filter by included or excluded GitHub labels to control what gets picked up.
  • •Choose separate planning and yolo execution backends and models.

Everything you need.

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

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.

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.
