THE WORK, FROM START TO FINISH
A small example: add a contributor guide. Follow the request, the proposed edit, and the approved result in the same thread.
01 / THE REQUEST
Open a project and start a thread. Your request, the agent’s work, and its changes stay together.
“Add a CONTRIBUTING.md with the three-step workflow: install, test, PR.”
A real demo task, ready to follow.
MORE ROOM FOR THE WAY YOU BUILD
Keep your agent access and your local projects. Bring the decisions, branches, and useful context into the same workspace.
CHOOSE PER TASK
Use the agent that fits the work, with your existing account. Each thread keeps its own provider and model.
For example · Ask Claude to explore a design while Codex works through a focused implementation.
MAKE ROOM FOR PARALLEL WORK
Start a worktree thread to give a task its own branch and working directory. Keep branch, PR status, and diffs close to the conversation.
For example · Fix a bug and explore a feature in separate worktrees, then review each change before merging.
KEEP WHAT THE WORK TEACHES YOU
Keep project notes in Pages and let agents maintain them when enabled. Connect a Markdown knowledge folder through the local OpenKnowledge companion.
For example · Save a project decision once, then let the next task find and build on it.

BEFORE YOU GET STARTED
A Mac with Apple silicon running macOS 13 or later, and access to Claude Code or Codex. Install your chosen CLI, sign in, and open a project in Modex. Your existing provider plan and usage still apply.
Yes. Modex is free and open source under the MIT license. Model access comes from your own Claude Code or Codex account; Modex does not include a model subscription.
The coding tools run on your Mac, in your local projects. Claude Code and Codex connect to their respective services using your account. Local projects do not mean offline model inference.
The companion currently connects on the same local network. Your Mac must be awake, running Modex, and reachable by your iPhone. It is available through the public TestFlight invitation, subject to tester availability.
Pages keeps local project notes with version history. When enabled, agents can help maintain them. Knowledge connects a Markdown folder through a separately installed local OpenKnowledge companion. You choose which projects can use these tools.
Yes. Explore Modex on GitHub, read the code, report an issue, or help shape what comes next.
Free & open source. Your tools. Your projects.
