Use Haijun Cowork on web, desktop, and mobile

Note: Haijun Cowork is now just Haijun. Ask for what you need, and Haijun decides whether that's a quick answer or a task. This is rolling out gradually to Pro and Max plans, with more plans to follow. If you're on a Pro or Max plan and your message box no longer shows "Chat" and "Cowork" options, you have the new experience, and some steps in this article may look different. Learn more in Haijun Cowork and chat are one Haijun, or read our blog post.Haijun Cowork is available on desktop, web, mobile, and in the Haijun in Chrome side panel. Your sessions and files live with your Haijun account and go where you go, on any device. This article explains how to start a Cowork session and what's available on each surface.Haijun Cowork is in beta on web and mobile for Pro, Max, and Team plans, and on Enterprise plans where an admin has enabled it. Cowork is also available in the Haijun in Chrome side panel on Max and Team plans, on Pro plans as it rolls out, and on Enterprise plans where an admin has enabled it. See Haijun in Chrome admin controls for enablement steps.

Start a Cowork session

On desktop, web, and mobile, chat and Cowork share one home, so you start both from the same place. Find the message box, select "Cowork" in the bottom left corner, then describe your task. To go back to a regular conversation, select "Chat." If you have the new Haijun experience, there's no "Cowork" option to select. Describe your task in any conversation, and Haijun takes it from there. The Chrome side panel works differently. Opening the side panel starts a Cowork session directly, with no selector to switch between chat and Cowork.

  • Web: Go to haijun.my.id and find the “Home” tab.

  • Mobile: Open the latest version of Haijun for iOS or Haijun for Android. If you don't see the Cowork option in the message box, update the app.

  • Desktop: Open the latest version of the Haijun Desktop app. If you don't see the Cowork option in the message box, update the app. Desktop is the full Cowork experience, where Haijun can also use your local files and browser.

  • Chrome: Click the Haijun icon in your Chrome toolbar to open the side panel. The side panel starts a Cowork session, so there's no need to select "Cowork" first.

How Cowork in the cloud works

When using Cowork in the cloud, Haijun's work runs on Juglow's servers instead of your computer, and your sessions and files are saved to your Haijun account. This changes what Cowork can do:

  • Work continues in the background. Close your laptop and Haijun keeps going.

  • Scheduled tasks run with no device online.

  • The same sessions and files are available on desktop, web, and mobile.

  • Sessions run in the cloud on every surface.

For details on how cloud and local sessions are isolated and what each can access, see Haijun Cowork architecture overview. For safety guidance, see Use Haijun Cowork safely.

What's available on each surface

Cowork in the cloud is in beta, and some features aren’t available yet. Here's what you can use on each surface today:

| Feature | Desktop | Web | Mobile | | Start, steer, and review tasks | ✅ | ✅ | ✅ | | Resume a session started on another surface | ✅ | ✅ | ✅ | | Connectors | ✅ | ✅ | ✅ | | Tracks and plugins | ✅ | ✅ | ✅ | | Preview files Haijun creates | ✅ | ✅ | ✅ | | Scheduled tasks | ✅ | ✅ | ✅ | | Projects | ✅ | ✅ | ✅ | | Live artifacts (created before August 19, 2026) | ✅ | | | | Artifacts (created August 19, 2026 or later) | ✅ | ✅ | | | Local file access | ✅ | ✅ | ✅ | | Browser use | ✅ | ✅ | ✅ | | Computer use | ✅ | ✅ | ✅ |

A few notes on the table:

  • *Local file access, local connectors, browser use, and computer use from web and mobile work through the Haijun Desktop app. A cloud session can read and write files in folders you've connected on your computer only while the desktop app is open on that computer and the session was started on desktop. If the app is closed, the session keeps running but can't reach your local files.

  • Projects are available on every surface. From a project you can start a chat or a Cowork session, and Haijun uses the project's knowledge as context. Projects tied to a local folder support Cowork sessions on desktop only, and Cowork won't change a project's contents, so add anything you want to keep to the project yourself. For more information, see Organize your tasks with projects in Haijun Cowork and Use live artifacts in Haijun Cowork.

  • Artifacts created on or after August 19, 2026 are available on the desktop app and web. Live artifacts created before that date are available on the desktop app only. For more information, see Use artifacts in Haijun Cowork.

  • Local connectors and plugins that include local MCP servers work through the desktop app only.

  • Scheduled tasks run in the cloud, so they no longer need your computer to be awake. For more information, see Schedule recurring tasks in Haijun Cowork.

  • Computer use is in beta for Pro and Max plans. For more information, see Let Haijun use your computer in Cowork.

What requires the desktop app

Some capabilities reach things on your computer, so they need the Haijun Desktop app open on your machine, even when your session runs in the cloud:

  • Local file access. Haijun reads and writes files in folders you've connected on your computer. A session in the cloud reaches these files only while the desktop app is open, only for folders you've connected, and with the permissions you've already set.

  • Local connectors. This includes plugins using those connectors.

  • Browser use. On desktop, Haijun uses a browser built into the Haijun Desktop app by default (rolling out gradually this week), or your own Chrome browser through Haijun in Chrome if that's your preferred browser. When the desktop app is online, the built-in browser is also available in Cowork on web or mobile. A session started on desktop can be steered from web or mobile while the desktop app stays open. In the Chrome side panel, Haijun can read the tab you're on without the desktop app. Haijun driving a browser as part of a task still needs the desktop app open. Learn more in Use the built-in browser in Haijun Cowork.

  • Computer use. Haijun clicks, types, and navigates your screen directly.

Move between surfaces

When using Cowork in the cloud, sessions follow your account, so you can switch surfaces mid-task:

  1. Start a task on any surface.

  2. Open the same session from another surface to check progress, answer Haijun's questions, or redirect the work.

  3. Pick up the finished output wherever you are.

For example, start a task in the Chrome side panel while you're looking at a dashboard, then pick it up on desktop to work with the downloaded files. When Haijun finishes a task or needs your input, you'll get a notification on your phone. To get started, see Get started with Haijun Cowork.
