Dia
AI browser from The Browser Company that pulls calendar, inbox, Slack and Notion context into briefs, reports and decks alongside normal browsing.
Updated 2026-08-02
Yes, within limits. Dia runs a free tier with paid plans above it.
Listed pricing: Free to download; a Dia Pro tier lifts chat limits.
Overview
Dia is The Browser Company's AI browser, and its own tagline is "A browser you won't dread opening". The framing on the site is work rather than search. Morning Brief assembles a day from calendar, inbox and key links. Reports synthesise across Slack, Notion, Calendar and GSuite. Decks generates presentation slides from the context the browser already has. Better Meetings auto-loads the relevant page, agenda and notes when a meeting starts, and Live Work keeps shortcuts to GitHub, Notion and wherever else work lives.
The rest is browser ergonomics, which is the part The Browser Company has always been good at. Profiles separate work from personal browsing, Splits put windows side by side, and tabs get grouped and named rather than shrinking into illegible slivers. Trackers and ads are blocked by default, users control what is shared, and the site states that Dia is covered under The Browser Company's SOC 2 attestation.
My read: the constraint is the platform, not the product. Dia currently runs on Apple macOS 14 or later with an M1 chip or newer. That excludes Intel Macs entirely, and the site says only "Dia is coming to Windows this fall" with a beta waitlist. For a browser, which is the single most switching-averse piece of software most people own, being unavailable on the majority platform is the whole story. Pricing is the other soft spot: Dia is free to download and a Dia Pro tier exists to remove chat limits, but the site is a JavaScript application that renders no pricing table to a plain HTTP client, so the Pro price is not something a reader can verify without installing the browser. Check it in-app before committing.
Is Dia free?
Yes, within limits. Dia runs a free tier with paid plans above it.
What the free tier covers: Yes. Dia is free to download and the free tier includes AI chat, with a cap on chat usage that the Pro tier removes.
Listed pricing: Free to download; a Dia Pro tier lifts chat limits.
Pricing verified . That is the date the plans were last re-checked against the vendor's own pages, not today's date. Confirm on the official site before you pay.
What the free tier leaves out
Read straight off the plan list below. Vendors move features between tiers, so check the current split before you pay.
- Dia Pro Not published in readable form on the site Removes the chat limit. Dia's site renders as a JavaScript application with no server-rendered pricing table, so confirm the current Pro price in the app or on the Pro page in a browser.
- Students Dedicated student offer The site carries a separate students page. Terms are presented there rather than on a general pricing page.

2 plans carry no published number: Dia Pro, recorded as “Not published in readable form on the site”; Students, recorded as “Dedicated student offer”. Nothing is estimated in its place. The vendor's own pricing page is the only source for those figures.

Is Dia worth it?
Worth it for Mac users who want the browser to double as a work dashboard, pulling calendar, inbox and workspace tools into one place instead of another set of tabs.
You can test that on the free tier before paying anything. The recorded trade-offs are listed below, and any one of them can settle the question on its own.
The 7.9/10 AI Score is an editorial read of published capability, price and shipping pace. Nobody here has hands-on hours with Dia. How we verify.
Worth it if
The strengths recorded against this entry.
- Pulls calendar, inbox, Slack and Notion context together instead of reasoning only about the tab in front of it
- Decks and Reports produce something usable rather than stopping at a summary
- Tab organisation, Profiles and Splits are genuinely good browser ergonomics, independent of the AI
- Trackers and ads blocked by default, with SOC 2 coverage stated on the site
- Free to download with AI chat included on the free tier
Not worth it if
Any one of these blocks your use case.
- macOS 14 or later on M1 or newer only, which excludes Intel Macs and every Windows machine
- Windows support is stated only as "coming this fall" with a beta waitlist and no firm date
- The site publishes no server-rendered pricing table, so the Dia Pro price cannot be checked without installing the browser
- Free-tier chat is capped, and the site does not state where the cap sits
- Deep workspace integration means granting a browser access to Slack, Notion, calendar and mail, which is a broad permission surface
What sets Dia apart
- Morning Brief opens the day with calendar, inbox and key links already assembled
- Synthesises across Slack, Notion, Calendar and GSuite rather than only the open page
- Decks turns the context it already has into presentation slides
- Profiles, Splits and organised tab groups address browser ergonomics, not just AI features
- Blocks trackers and ads by default and is covered under The Browser Company's SOC 2 attestation
Key features
Morning Brief
Opens the day with calendar, inbox and key links already summarised, which is the feature that argues for the browser being the first thing you open rather than one of several apps.
Synthesis and Reports
Aggregates across Slack, Notion, Calendar and GSuite into reports, so the context is the workspace rather than the current tab. This is the main separation from an assistant that only sees the open page.
Decks
Generates presentation slides from the context Dia already holds, turning material collected during browsing and meetings into something presentable without a round trip through another tool.
Better Meetings and Live Work
Better Meetings auto-loads the meeting page, agenda and notes at the right time. Live Work keeps direct shortcuts to GitHub, Notion and other work locations rather than making you hunt through tabs.
Profiles, Splits and organised tabs
Separate work and personal browsing modes, side-by-side window layouts, and grouped and named tab collections. Ordinary browser craft, and the reason people stayed with this company's previous browser.
Privacy defaults
Trackers and ads blocked by default, user control over what data is shared, encryption options, and coverage under The Browser Company's SOC 2 attestation.
How it compares
| Tool | Best for | Pricing | Score |
|---|---|---|---|
| Dia | Mac users who want the browser to double as a work dashboard, pulling calendar, inbox and workspace tools into one place instead of another set of tabs. | Free to download; a Dia Pro tier lifts chat limits | 7.9/10 |
| Comet | People who want an assistant that acts on the page in front of them, and who would rather switch browsers than add another tab to their workflow. | Free to download; Perplexity Max at $200/mo unlocks the highest limits | 8.4/10 |
| Notion AI vs Notion AI → | Notion users who want an assistant that already knows their pages, databases, and documents for summaries and answers. | From $10/mo | 9/10 |
| Granola | Product managers, VCs, and founders in frequent external meetings who want polished notes without a visible bot recording the call. | Freemium — Free 25 meetings, Pro $10/mo, Business $25/user/mo | 8.8/10 |
| Gamma | Founders, marketers, educators, and consultants who need a polished presentation, document, or webpage produced from a prompt or outline. | Free tier, Plus $10/mo, Pro $20/mo (billed annually) | 8.5/10 |
