Dia

What it does

Dia treats the browser itself as the assistant. You can ask it to gather what is across your tabs, draft from the page you are reading, or run a short multi-step task without leaving the window.

The bet is that most people do not want a separate AI app, they want the one they already have open to be smarter. It is early software; the simple reading and drafting jobs are the reliable ones.

Standout features

• Chat with the current tab and tab groups
• Draft text using page context
• Short agentic tasks inside the browser
• Keyboard-first, minimal interface

Main job: bring AI reading and drafting into the browser window instead of a separate chat app.

Best for

Use it when your work lives in a dozen tabs and you want to pull them into one draft or summary without switching to another app.

Getting started

Install Dia, open the tabs for a task, then use the address-bar assistant to ask for a summary or a draft. Give it one tab group at a time so you can see what it used.

Watch out for

Watch out: agent actions inside a logged-in browser can submit forms. Keep it on read-and-draft tasks until you have watched how it handles a real site.
