What Dia does
Who it’s for: people who work on a Mac, spend all day in online tools, and lose time piecing together scattered information.
Query your work tools
Once connected, Slack, Gmail, Notion, Outlook, Google Calendar, GitHub, or Figma become sources. Dia searches them to answer, without you opening each tool.
Morning Brief: the morning briefing
Every morning, Dia gathers your calendar, your inbox, and the important links. It flags emails waiting for a reply and what you missed the day before.
Also
- Reports: a formatted report
- Decks: a presentation from your sources
- Meetings: prepared and remembered
- Organized tabs, profiles, and split view
- Skills: your saved prompts
Dia pricing
Prices are published in dollars. Usage is counted in “Tasks”: a simple request uses a fraction of one, a complex request more, and the quota resets every month. Credit blocks of $20 can be added. Paid plans apply to new users since August 17, 2026; existing users keep their access and will be notified 30 days before any change. Recorded on October 3, 2026.
| Plan | Price | Who it’s for |
|---|---|---|
| Better Browser | $0 | A polished browser, without AI |
| Better Answers Recommended to start | $20 per month | Asking questions about your pages and tools |
| Better Days | $100 per month | Making Dia your main workspace |
| Enterprise | Custom pricing | Organizations that want custom security guarantees |
What the free plan includes
The browser alone is free: profiles, tab groups, split view, ad and tracker blocker, sync. This plan includes no AI features. New users get a 14-day trial of the most complete plan, no credit card required.
Nova’s advice
Use the 14-day trial to see whether querying your tabs and tools really helps you. If so, “Better Answers” is enough to begin. At $100 per month, “Better Days” is only worth it if the morning briefing and the reports help you every day. And if you only want a good browser, the free plan is enough.
A first try, in 5 minutes
Your data. Your chats, your history, and your bookmarks stay encrypted on your Mac. When you ask a question, the relevant content goes to an outside AI, which is not allowed to keep it.
What it does less well
- Mac only. The Windows version is announced but not released, and the website mentions no phone app.
- AI is paid: the free plan contains none. Expect $20 or $100 per month, with a monthly quota.
Ask for a summary of three tabsDia- Open three pages on the same topic, for example three vendor proposals.
- Press ⌃ + ⌘ + Enter: the command bar opens on the chat.
- Type @ and pick your three tabs from the list. Without this, the chat does not see your other tabs.
- Paste the prompt below and send it.
- Check two figures on the original pages before you use the result.
The prompt to copy
From the tabs I just added, write a five-point summary, then a comparison table: price, lead times, and weak points of each proposal.
