Kimi WebBridge
The browser extension, formerly WebBridge, that an agent uses to operate pages.
WebBridge is the browser extension
Kimi WebBridge is the old name of Kimi's browser extension. The help center introduction says it outright: Kimi Browser Extension, formerly Kimi WebBridge. A search for Kimi WebBridge still means this add-on. It lets an agent open pages, click buttons, fill forms, and extract information, and it can turn a repeated site into a skill the agent reuses.
It is not a VPN, and it is not a general ad blocker. The point is page control for an agent. You can also open a sidebar from the toolbar, sign in with your Kimi account, and ask Kimi to operate the current tab. Remote control is the other mode: Kimi Work or another local agent drives the extension.
What you need installed
The help page's requirements are macOS or Windows, Chrome or Edge, and a stable network. It lists a companion: Kimi Work or another local agent. The local-agent list on that page names Claude Code, Codex, Cursor, Kimi Code, and Hermes Claw, as well as Work itself. A phone-only Kimi chat does not replace the extension.
One documented path is inside Work: download Work from Kimi, switch to Work mode, install the extension from the plugin marketplace, then give a task in the sidebar or in Work. The other path is to ask a local agent to run the install for your operating system. Sign-in for the sidebar uses the Kimi account from login. This site cannot connect the extension for you.
What to allow it to do
The extension acts as you, in a browser that may already be signed into mail, banking, or work tools. Kimi's introduction to Work makes the same point: it keeps the existing session so you are not logging in again. Before a task, decide which profile it may touch. A spare browser profile with only the accounts you intend is safer than your everyday profile.
WebBridge does not answer 'what is an agent.' That is Kimi Agent. It also does not set your plan limits. Clicking through a long site spends the same membership credits as other agent tools. If the extension installs and then refuses to run a job, check credits on pricing and that Work or the local agent is actually connected.
Steps
- Install Kimi Work or a supported local agent. The help page treats the extension as a companion to Work or to a local agent such as Kimi Code, not as a lone chat window.
- Add the extension in Chrome or Edge. From Work's plugin marketplace, or by asking the local agent to install it. Use the browser you want the agent to drive.
- Sign in on the sidebar. Open the Kimi icon and sign in with your Kimi account if you want chat plus control of the current page.
- Give a narrow first task. Ask it to read one page or download one file you can check. Widen access only after that run looks right.
Questions
- What is Kimi WebBridge?
- The former name of the Kimi browser extension. It clicks, types, and extracts on pages so an agent can finish a web task. Kimi's help center documents the rename.
- Which browsers work?
- The introduction lists Chrome and Edge on macOS or Windows. It does not list a phone browser as the host.
- Can I use it without Kimi Work?
- The help page also allows other local agents, and it names Claude Code, Codex, Cursor, Kimi Code, and Hermes Claw. The sidebar still signs in with a Kimi account.
- Will it see passwords I type?
- It operates the page, so a task that includes a login form can interact with that form. Prefer a browser profile that only contains the accounts you want the agent to use, and read each approval.
