Chinese AI lab Moonshot AI has launched a browser extension called Kimi WebBridge, giving users a way to let an AI agent click, scroll, fill forms, and navigate inside Chrome or Edge. The company says all browser sessions stay on the user's machine — none of the data is sent to external servers.
How the extension handles privacy
Kimi WebBridge runs entirely locally. When the AI agent interacts with a webpage, every action — moving the cursor, typing into a field, submitting a form — happens inside the browser on the user's device. Moonshot AI said no session data is transmitted to its cloud or any third party. That design sidesteps a common user concern about AI tools that phone home with browsing habits.
What the agent can do
The extension acts as a bridge between the user and the browser, letting the AI take over routine tasks. It can click links, scroll through long pages, fill out text boxes, and step through multi-step web forms. The agent works inside both Google Chrome and Microsoft Edge, two of the most widely used browsers. Moonshot AI hasn't detailed the underlying model powering the agent, but the extension integrates with the company's existing Kimi AI assistant.
Why local processing matters
Keeping AI-driven browsing local isn't a new idea, but it's still rare in consumer extensions. Most browser-based AI agents either send snippets of page content to a remote server or require the user to grant full network access. Kimi WebBridge avoids both by processing everything on the device. That means sensitive information — login credentials, financial details, personal messages — never leaves the computer. For users who don't trust cloud-based AI, the approach offers a more private alternative.
What's still unclear
Moonshot AI hasn't said whether the extension will remain free or if it plans to charge for advanced features. The company also hasn't disclosed the system requirements beyond needing a modern version of Chrome or Edge. Users who want to try it can install the extension from the Chrome Web Store or Edge Add-ons site. It's too early to tell how well the agent handles complex sites with dynamic content or CAPTCHAs — the real test will come from early adopters putting it through daily use.
