TL;DR:
As of June 2026, Dia is on version 1.33.0 ("Everything in Its Place", released May 28, 2026) and remains an actively developed, AI-first Chromium browser from The Browser Company, now an Atlassian subsidiary. The headline shifts since the start of 2026 are cross-device Sync (shipped in v1.26.0), a run of performance work, and steady AI and tab-management polish. Dia is generally available on macOS 14+ with Apple Silicon only; a Windows version is still in development behind a waitlist, and there is no public iOS app or Linux build. Pricing stays freemium: a free tier with limited AI usage and a Pro plan at $20/month. The full month-by-month log, platform matrix, and roadmap signals are below.

What Dia is, in one paragraph
Dia is an AI-first web browser built by The Browser Company of New York, the team behind Arc. It is built on Chromium, so Chrome extensions work, and it puts a conversational AI assistant in the sidebar as its central feature rather than as a bolt-on. The Browser Company became an Atlassian subsidiary in October 2025 after a $610 million acquisition (BusinessWire, October 21, 2025). Dia is positioned as the company's go-forward browser while Arc sits in maintenance mode. This page tracks what Dia actually ships, refreshed monthly, so the "latest" claims here carry a date instead of a vague "recently."

Two facts on this table change most often and are worth re-checking at the source before quoting: the current version and the Windows status. Both are verified against the official release notes and The Browser Company's Windows page for this June 2026 update, with primary links in the sections below.
Latest updates (reverse chronological)
This is the running log. The newest month sits at the top. Older entries stay in place so the trajectory is visible.
May 2026
Dia reached version 1.33.0, "Everything in Its Place," on May 28, 2026 (Dia release notes). The May releases leaned on refinement rather than brand-new pillars:
- The sidebar now rubber-bands when dragged past its maximum or minimum width, a small interaction-polish touch.
- Tab switching was made snappier by removing a legacy system, part of a broader speed push that also produced the v1.24.0 release titled "Dia got faster."
- Tab groups now get an automatically selected emoji that represents what is inside the group, so a glance is enough to recognize a group.
- The Tab Switcher picked up a new layout with updated colors and shadows and now hides tabs a user has not visited in a while.
- Confluence joined Notion and Gmail in Live Groups, so Confluence docs needing attention surface alongside the others. The Atlassian ownership is starting to show in the integration list here.
- Notion mentions, comment threads, and share invites began surfacing inside the chat sidebar, reducing context switching.
April 2026 and earlier in Q2
The standout structural change of the spring was Sync, which shipped in v1.26.0, "Pick up where you left off" (Dia release notes). With Sync, settings began following the user across devices: Tabs, Privacy, Profiles, Memory, Shortcuts, and more set on one machine show up already configured on another. This closed one of the more visible gaps against established browsers. The period also included the v1.24.0 performance release ("Dia got faster") and v1.28.0 ("A closer look"), continuing the pattern of frequent, incrementally numbered releases rather than large quarterly drops.
January 2026 (baseline reference)
For continuity with the prior tracking baseline, the January 2026 state was v1.16.0 (January 28, 2026), which added the ability to pin tab groups, a dedicated Tabs settings pane, and the announcement that Manifest V2 extensions would be phased out in favor of Manifest V3. Tab Groups proper had arrived earlier, in v1.9.0 (December 10, 2025), with Tab Groups for Meetings following in v1.14.0 (January 14, 2026). These dates matter because they are frequently misreported: Tab Groups were a December 2025 feature, not a 2026 one.
Platform availability matrix
Platform support is the question most "dia browser update" searches are really asking, so it gets its own section.
| Platform | Status (June 2026) | Notes |
|---|---|---|
| macOS (Apple Silicon) | Generally available | macOS 14 or later, M1 or newer required |
| macOS (Intel) | Not supported | Apple Silicon is a hard requirement |
| Windows | In development | Waitlist signup on the official Windows page; no public release date announced |
| iOS / iPadOS | Not available | No standalone Dia app; Arc's mobile companion is a separate product |
| Linux | Not available | None announced |
| Homebrew (brew) | No official cask | The Browser Company distributes Dia via direct download, not an official Homebrew cask |
A note on the Windows question specifically, because conflicting claims circulate: as of June 2026, The Browser Company's own Windows page offers a waitlist rather than a general-availability download, and independent reference pages describe the Windows build as still in development. Treat any "Dia is now on Windows" claim from a non-official aggregator with caution until the official site flips the waitlist to a direct download. This page will update the moment that happens.
On Intel Macs, the answer is simpler and unlikely to change: Dia requires Apple Silicon, so Intel Macs cannot run it at all. Users on Intel hardware who want Dia-style AI browsing have to look elsewhere or stay on their current browser.
Pricing
Dia uses a freemium model verified as of June 2026:
- Free tier: core browsing plus a capped amount of AI usage. Light users who only invoke the assistant a few times a week can stay free.
- Dia Pro: $20/month, with unlimited chat and skills usage, personalized memory, and a free trial. The Browser Company launched this Pro subscription in August 2025 (TechCrunch, August 6, 2025).
CEO Josh Miller has signaled an intent to offer multiple tiers over time, ranging from a few dollars to much higher business-grade plans, so the two-tier structure above may expand. The $20 Pro price is the figure to quote today.
What's coming (roadmap signals)
The Browser Company does not publish a formal public roadmap, so this section reads signals from shipped releases and official statements rather than promises:
- Windows is the most-anticipated platform expansion and is actively in development behind a waitlist. It is the single most likely "big" announcement for the rest of 2026.
- Deeper Atlassian integrations are a clear direction. Confluence support in Live Groups (May 2026) is an early example of Dia leaning into its parent company's product surface, and more Jira and Confluence touchpoints would fit that pattern.
- Continued AI and memory depth is the consistent throughline of every release. Sync, Memory, and Live Groups all point at Dia trying to be the browser that already knows the user's working context.
- Manifest V3 transition is underway following the v1.16.0 announcement, in step with the broader Chromium ecosystem.
No Spaces and no direct Arc-data import have appeared as of June 2026. Dia still organizes with profiles in separate windows rather than Arc-style Spaces, and migrating from Arc remains a manual recreation rather than a one-click import.
How Dia compares to Arc's trajectory
Dia is The Browser Company's answer to a hard lesson from Arc: a beloved, heavily reimagined browser is difficult to sustain and monetize. Where Arc reinvented the whole interface and then stalled in maintenance mode, Dia is a more conventional Chromium browser with AI as the differentiator and a paid subscription from early on. The release cadence tells the story. Arc's updates slowed to a trickle; Dia is shipping numbered releases on a near-weekly basis through 2026.
For a user weighing whether Dia is the safe long-term bet that Arc was not, the signals are mostly positive on the activity axis, with the usual caveat that Atlassian ownership means Dia's direction now serves an enterprise parent's strategy as much as the original indie vision. The dedicated Arc-versus-Dia decision, including what transfers and what does not, lives in the Arc Browser vs Dia Browser breakdown rather than here.
The cross-browser gap Dia does not close
Dia, like every browser, owns only its own tabs. A user who runs Dia for AI browsing but keeps Safari open for Apple-ecosystem work, or Chrome for a work profile, ends up with separate tab worlds that do not talk to each other. Dia's Sync keeps Dia consistent across devices, but it does not surface a Safari tab or a Chrome tab inside Dia. That is a structural limit of the single-browser model, not a Dia flaw.
Why we recommend SupaSidebar
SupaSidebar is a macOS app that brings Arc's sidebar to every browser, one sidebar for tabs, bookmarks, files, and apps across Safari, Chrome, Firefox, Arc, Zen, Vivaldi, Brave, Helium, and Dia (25+ browsers in total). It is not a browser and not a browser extension. It is a native Mac app that adds a sidebar to any browser, including Dia itself.
For someone tracking Dia, the practical fit is this: Dia can be the AI browser while SupaSidebar handles the tabs, links, and spaces that live across all the browsers a person actually uses. SupaSidebar runs on Intel Macs as well, which Dia does not, so it also serves the Intel users this page leaves out. A free tier is available at supasidebar.com.
Conclusion: where Dia stands in mid-2026
Dia in June 2026 is an actively developed, AI-first Chromium browser on version 1.33.0, generally available on Apple Silicon Macs and freemium with a $20/month Pro plan. The year's most meaningful additions are Sync and a string of performance and integration work, with Confluence support hinting at the Atlassian roadmap to come.
For Apple Silicon Mac users curious about AI-native browsing, Dia is worth trying today, and the active release cadence makes it a more credible long-term bet than Arc became. For Windows users, the honest answer is to join the waitlist and wait; there is no public release date yet. For Intel Mac users, Dia is simply off the table on hardware grounds. And for anyone running Dia alongside another browser, the tab-fragmentation problem stays unsolved at the browser layer, which is where a cross-browser sidebar comes in.
