Try Dia
Overview
Dia is what happened after The Browser Company decided Arc had reached the end of its road. Arc had a devoted following and an interface people wrote love letters about; it also had a ceiling. Dia is the company's answer to what a browser looks like when the assistant is designed in from the first sketch rather than added to a sidebar, and it shows — this is comfortably the best-looking product in the category.
The interesting technical choice is memory. Where rivals attach memory to an account or a chat thread, Dia builds it around tabs and around what the company calls skills: reusable instructions you teach the browser once and invoke later. It is a more browser-native idea than a chat window that happens to live next to your web page, and when it clicks it feels like the right answer to the whole category.
It is also the least finished product here. Features arrive and change, edges are rough, and reviewers who use it daily consistently describe it as not yet a safe default. The August 2026 acquisition of The Browser Company by Atlassian for $610 million cuts both ways: it removes the funding risk that kills ambitious browsers, and it raises a fair question about whose roadmap Dia now serves.
Key Features
Tab-Based Memory
Memory is organised around what you have been browsing rather than around a chat history, so context follows your work instead of your conversation.
Skills
Teach Dia a repeatable instruction once — a summarising style, an extraction format, a review checklist — then invoke it by name on any page.
Best-in-Class Interface
The clearest, calmest design in the AI browser field, inherited from the team that built Arc's much-loved interface.
Conservative by Default
Less page content leaves the machine automatically than in rivals, which reviewers consistently rate as the safest default posture among mainstream AI browsers.
Tab Organisation
The Browser Company's core competence: managing many tabs without the tab strip becoming an unreadable smear.
Atlassian Backing
Post-acquisition, the funding question that hangs over independent browsers no longer applies.

Best Use Cases
Dia Excels At:
- Designers and writers who care how their tools feel
- Former Arc users looking for where that team went
- Users who want AI browsing with conservative data defaults
- Anyone evaluating where the category is heading rather than what it does today
May Not Be Ideal For:
- Teams that need a stable, standardised browser now
- Users on platforms Dia does not cover
- Anyone whose main need is heavy agentic automation
How It Compares
Dia vs Perplexity Comet
Comet does more and costs nothing; Dia is better designed and more careful with your data. Comet is the pragmatic choice today. Dia is the one to watch, and the one you will enjoy using more.
Dia vs Arc
Dia is Arc's successor from the same team, not a competitor to it. The Browser Company wound Arc down to focus on Dia, which is the source of much of the community's frustration and much of Dia's design pedigree.
Final Verdict
Our Recommendation
Dia is the most interesting browser in this category and the hardest to recommend today. The design is superb, the tab-memory and skills model is the smartest structural idea anyone has had about AI browsing, and the privacy defaults are the most conservative among mainstream options. It is also visibly unfinished, and Atlassian's $610 million acquisition leaves an open question about whose product it becomes. Install it as a second browser, use it for research and writing, and keep something dependable for the work that has to ship today. In a year this may well be the recommendation rather than the runner-up.
