Threads, diffs, terminals and a browser in one window

Move over the dots to see what each part of the window does.

An Eizen window with a thread open
  • Threads with lamps. Blue is working, amber is waiting for you, green has finished.
  • Breadcrumb menus. Click the computer, project or thread to jump to another one or act on it.
  • Git, in the header. Branch, commit, and the state of GitHub Actions.
  • Panels. Diff, tasks, browser, terminal and editor each open beside the thread.
  • The composer. Account, model, effort and permission mode, always in sight.
  • Account meters. How much of each usage window every account has left.

Composer

Steer a running agent or queue the next message

While an agent works, Enter sends your message straight in or holds it for the end of the turn, whichever you set as the default. Ctrl+Enter does the other one.

  • @ finds files and folders in the project.
  • / lists the commands the agent knows.
  • Paste or drop images and files.
  • Select text in the thread and ask about it, or branch a side chat from there.

Usage

See what each model and each agent used

The new-thread screen shows tokens for today, 7 days and 30 days, your most used model and what those tokens would cost at API prices. The Tasks panel breaks a thread down by sub agent.

Git

Commit, branch and open the pull request from here

The usual git work stays in the window, including the parts people go to GitHub for.

Commit

Commit with your own message, or have one written from the diff.

Branches

Switch, create and delete. A merge preview lists what would conflict.

Pull requests

Write the title and body from the branch, then open it.

GitHub Actions

A spinner in the header follows the runs on your branch.

Repositories

Projects with several checkouts get one view of all of them.

Branch history

A snapshot after every turn, kept outside your repository.

Accounts

Keep work and personal plans side by side

Add every Claude account you pay for and pick one per thread. The meters at the top show what's left in each usage window. New threads can go to whichever account has the most room.

Relay can move a thread to another account at a limit. It's off by default, because rotating between personal accounts may conflict with a plan's terms.

Built-in guide

Ask the app how the app works

Eizen ships with a user guide that the agent can read. Ask in any thread how to add an account or where the logs live, and it answers from the guide using the labels you see on screen.

Open a lane on the repo you were going to work on anyway

The setup checklist handles Claude Code, sign-in and Git, so you won't need a terminal.
