Comparison - AI web browser

Winy vs Dia

Dia puts AI inside your browser; Winy puts your browser, terminals, notes and agents on one board.

Dia is a web browser for Mac and Windows from The Browser Company, now part of Atlassian, built around AI that works across your tabs and work apps, with a free plan that has no AI.

Winy is a native app for Mac, iPad and iPhone that gives your work one infinite board, where a web page can sit as a live card beside terminals, notes, Pencil ink, images and agents.

Dia brings AI into the browser for knowledge work, while Winy brings your coding agents, pages and notes together on a board you arrange yourself.

Which one is for you

Choose Dia if

You want an AI that reads your open tabs and work apps and answers questions about them.
You want a morning brief of your calendar and inbox, or slides drafted from what you gathered.
You want a modern browser on Mac or Windows, free if you skip the AI.

Choose Winy if

Your AI work is coding agents like Claude Code and Codex, and you want them running live next to your pages.
You want your pages, terminals and notes for one task on one board, not across tabs.
You want to draw over a page with the Pencil on iPad.
You want your notes and sketches visible to the agents working beside them.

Using both

Keep Dia as your browser and its AI for answers across your tabs and work apps. In Winy, the pages that belong to a coding task go on the board next to its terminals, notes and the Claude Code or Codex sessions doing the work.
