Dia

What it does

Dia is a web browser for macOS and Windows with an AI assistant built in. It takes in the pages you have open and content from connected work tools such as Slack, Notion, Teams and Google Workspace, and produces answers, written reports, a daily Morning Brief covering calendar, inbox and key links, and slide decks built from scattered context.

People use it as their everyday browser, asking questions in plain language instead of searching through threads and tabs. It also groups related tabs under descriptive names, surfaces places where work is happening (such as GitHub and Notion) in the tab bar, opens meeting pages and notes with a countdown, saves split-screen layouts, and keeps separate profiles for work, freelance and personal use, each with its own tabs, logins and AI. Privacy toggles control tracker blocking, memory, and content sharing.

It suits knowledge workers who spend the day across documents, chat and meetings, and teams that want admin controls: Dia for Work adds SSO and admin tools. Downloading is free. It runs only on macOS and Windows, so mobile and Linux users are not covered. Connected-tool coverage beyond the named apps, and any paid plans, are not detailed.
