A coding agent on your own free chat.z.ai account.

What is in 0.2.8.3

What it does today.

Each line says how far it has been tested. "Tested in a simulator" means our automated tests against a stand-in for chat.z.ai, not real traffic.

• Three modes, one project

  Chat, On-device and zAgent sit in one mode bar. The conversation and the files follow you when you switch.

  Since 0.2.0 · Cloud folded into Chat in 0.2.8
• Fast or DeepThink

  One switch per chat. Fast answers straight away; DeepThink lets the model think first. Works in all three modes.

  Since 0.2.4 · tested in a simulator; DeepThink with chat.z.ai's cloud agent not yet checked on chat.z.ai
• Another model takes over when one is busy

  If the model is busy, rate-limited, fails or goes quiet, the same message goes to the next model, at most three tries. The answer says which model replied. Chat, On-device and zAgent.

  Since 0.2.5 · tested in a simulator; real-traffic test pending
• Or let it ask you first

  Turn the automatic switch off in Settings, Chats. A small card offers Try next, Retry or Choose model, and moves on by itself after 10 seconds unless you cancel.

  Since 0.2.5 · tested in a simulator
• Share a session

  Invite someone into your chat. You approve each guest; they see the answers as you do, and never the app's hidden instructions. Guests follow your Fast or DeepThink choice.

  Since 0.2.5 · invite links fixed in alpha.2: tested end to end over the internet on one machine, not yet between two phones
• zHelp, when something breaks

  A Help and community entry in the side menu and in Settings, and a link on every error card, to the zHelp community.

  Since 0.2.5 · link opening on a real phone not yet checked
• Files and diffs

  Every file the agent writes lands in a file tree with per-file diffs. HTML pages preview in the app.

  Since 0.1.x
• Tools on your phone

  In On-device mode the agent reads, writes and edits files in the app's own workspace. Every write asks you first.

  Android app only

Phone-width captures (412 px). "Live" ones were taken on chat.z.ai with an earlier 0.2 build; "test run" ones come from the project's automated tests with a simulated chat.z.ai.

Three modes

Pick the kind of help you need.

The mode bar sits at the top of every screen. The project button beside it opens your files.

Privacy

Your account, your device.

There is no zAgentix server. The app talks to chat.z.ai from your own device, in your own session, the same way the website does.

Download

Get the app.

For Android and Mac. Neither is in an app store, so your phone or Mac asks you to allow it once.

Android

Android 8.0 or newer. The APK is served from this site; the same file is also on GitLab.

macOS

macOS 13 or newer. The same app code as Android 0.2.8.3, as a native Mac window (the SVG preview comes in the next Mac build). The zips are hosted on GitLab.

Browser extensions

Install once. It opens on chat.z.ai by itself.

The extension adds zAgentix on top of your own signed-in chat.z.ai tab every time you open it. The app code is inside the extension (nothing is downloaded when it runs), and it can only see chat.z.ai. Free; not in the browser stores, so you load it in Developer mode. Version 0.2.5.2, app 0.2.8.3.

No extension? The bookmark still works on any browser, phones included.
