The Browser Company’s new AI browser rolls out to private beta testers

The Browser Company’s new AI-powered browser is now available in an invite-only beta. Called Dia, the browser was towards the end of 2024, and is built around the deep integration of what its maker calls “the most personal AI on the market”.

Dia allows you to “chat with your tabs” and will adapt and learn the more you use it. You can open an AI chat on any webpage without having to leave the tab, where the built-in bot can search the web, compare websites, answer questions about the content displayed, and even draft a document in the tone of a specific webpage. You can set preferences to customize the chatbot’s tone and style for writing tasks, as well as its coding language and how it talks to you.

All of these features live within Dia’s URL bar, with the idea being that you don’t need to visit dedicated pages for other LLM chatbots such as ChatGPT to get things done with AI.
