Customaise vs AI Browser

AI Browsers weld the agent to the browser; page content goes to the vendor every time the agent acts. Customaise is a Chrome extension you drive from your IDE, so your tabs, sign-ins, and bookmarks stay where they are.

Customaise vs ChatGPT Atlas, Perplexity Comet, Dia: keep the Chrome you already have, with the page-route on a switch. Honest comparison across all three.

When should you use Customaise vs AI Browser?

You want to stay in Chrome. Your workflows hit internal tools, SaaS dashboards, or behind-login pages where vision/DOM-parsing struggles. You use an IDE agent and want it to act on the same browser tabs as the in-browser AI. You want page content routed through your own IDE's provider rather than the AI-Browser vendor.

When is AI Browser the better pick over Customaise?

You want a new browser experience built around the agent. You mostly act on consumer sites where DOM parsing usually works. You don't want to install extensions; you want it integrated. You're comfortable with the vendor seeing your page content when the agent acts.

Can you use Customaise and AI Browser together?

AI Browsers will integrate native WebMCP over time. AgentScripts cover what native does not. Both surfaces benefit from each other; many users will run an AI Browser as their default and Customaise in another Chromium for the typed-tool workflows.
