Splitkick: the power-user edition of Jean
Why Splitkick exists, what it adds to Jean, what it does not do yet, and where the credit goes. Free, open source, for macOS on Apple Silicon.
Splitkick is built on Jean, the open-source agent workspace by coolLabs. We use Jean every day for code, company data and writing, and we kept adding what we missed. Splitkick is where those additions ship.
Why a separate edition
Jean is a great base: agents in git worktrees, a clean desktop app, a headless server. We wanted more: a phone layout that works, one window per remote host, a preview pane for the files our agents produce, plan approval and agent questions, and faster releases. Some of that is too opinionated for upstream. So Splitkick ships it, and sends the generic fixes back.
What Splitkick adds
Everything below is in Splitkick today and not in Jean:
- A phone layout with tab navigation and a keyboard-safe composer, and “Add to home screen” on the iPhone.
- One window per remote host, so a Mac and a home server sit side by side.
- A preview pane for Markdown, PDFs, images and video, right next to the chat. File paths in answers are links; inline images zoom; “Reveal in Finder” works.
- Plan approval and agent questions (Claude Code’s
AskUserQuestion), with the same options on every device. - Fork a session from any message, even while it runs. Cancel safely: the prompt goes back to the input, the conversation stays.
- Star, pin, label, sort and pause sessions. A home view, “Recent”, and search across all projects and messages.
- Plan usage and the signed-in account per agent backend. The Claude login is only read, never refreshed, so no surprise logouts.
The full list, with the status of every feature, is on the features page.
What it does not do yet
We say “Roadmap” when something is not built. Today that means: no push notifications to the phone (desktop notifications only), no Splitkick build of the headless server (Jean’s upstream server works), no Linux or Windows desktop builds, no projects without git, and no Forgejo or Gitea dashboard in the app (any git remote works; issues and PRs go through tea or fj in your agents).
Splitkick stores everything on your disk and has no account and no telemetry. The agents you run still send prompts and file contents to their model providers, through the CLIs and subscriptions you already have.
Credit and licence
Jean is published by Andras Bacsai and coolLabs under the Apache License 2.0. Splitkick keeps that licence and that credit. The source is on GitHub, and generic fixes go back upstream.
Get it
Splitkick is free, for macOS on Apple Silicon. The download page has the build, the checklist of what you need (git and at least one signed-in agent CLI), and the three install steps.
