Best Dia Alternatives in 2026
Dia is the AI browser from The Browser Company of New York, the team behind Arc. The browser half is free and unusually tidy: profiles and tab groups, split view, picture-in-picture, a built-in ad and tracking blocker, cross-device sync. The AI half, Ask Dia, answers questions about whatever page you have open and pulls context from the work tools you connect, which Dia's site lists as Slack, Notion, Teams, GSuite and GitHub. It scores 4.2/5 against our 8-parameter framework. People still shop around, and usually for three reasons: Dia's site lists it for macOS with Windows coming soon, every AI feature sits behind a paid plan, and usage is metered in Tasks rather than in anything you can count before you buy. The five below split into browsers that do the same job on more hardware and agents that attempt more.
Why look for Dia alternatives?
Start with what is good, because for many Mac readers the answer is to stay put.
- → The free Better Browser plan is a real browser, not a teaser: tab groups and profiles, split view, picture-in-picture, an ad and tracking blocker, cross-device sync
- → Ask Dia draws on the tools you connect, not only the page in front of you
- → The trial is unguarded. Dia's pricing page states: “Every new Dia user gets a 14-day free trial with access to the Dia Better Days plan. No credit card is required to start.”
- → Dia is where The Browser Company's attention now goes. Arc's own site says “Arc receives Chromium updates only” and points visitors to Dia instead
And the reasons people still leave, most of them off the live pricing page.
- → Platform. Dia's site lists it as “Available for macOS · Windows coming soon”, and our Dia review records the requirement as macOS 14 or later on Apple silicon, M1 or newer
- → All of the AI is paid. The free Better Browser plan has no AI features, so Ask Dia starts at Better Answers, $20 a month
- → The step above that is a jump. Better Days is $100 a month, and what it adds over Better Answers is “6x more tasks and chats” plus the daily Morning Brief, reports, decks and recaps
- → Metering. Dia bills AI work in Tasks, which its pricing page calls “our unit for calculating effort”, and prints no Task figure for either paid plan. Monthly allowances do not carry over; extra usage is sold in $20 credit blocks that roll over for up to three months from purchase
- → Phones. Dia is a desktop browser; The Browser Company's mobile product is Arc Search, a separate app with a different feature set, and the fifth entry here

How they compare to Dia
Two score higher than Dia, and every one of them runs on hardware Dia does not. Skim the highlights or click through for the full review.
Comet · 4.5/5
Best for the same trick, free, on Mac, Windows, iOS and Android.
Comet is Perplexity's browser and the closest like-for-like swap here. The Comet Assistant answers questions about the pages you already have open rather than asking you to paste them somewhere else, and it will also act on them: Perplexity's own examples include comparing how outlets cover a story and turning a syllabus into a study plan. Two differences settle it against Dia. Reach: Perplexity's Comet page states it is “Available for Mac, Windows, iOS, and Android”, where Dia's site lists macOS with Windows coming soon. And the bill: Comet's own FAQ answers the free question with “We will always provide a free version of Perplexity for all users, and that will include Comet”, so the assistant costs nothing, while Ask Dia starts at $20 a month. The paid add-on alongside it is Comet Plus, $5 a month standalone and included with Perplexity Pro and Max, which per our Comet review buys premium publisher content rather than more AI. That review's cautions apply: agentic browsing is early, any agent that reads web pages can be steered by hidden instructions in them, and Comet is worth most if you already use Perplexity. If you want what Dia's AI does without paying for it, or you need Windows, iOS or Android, Comet is the one to install.
Fellou · 3.9/5
Best for handing multi-step web work to an agent.
Fellou is a bigger swing than Dia, a less finished one, and the lowest-scoring entry here. It calls itself an agentic browser: you give it a goal and its Deep Action agent plans and works through the steps while you watch. Deep Search researches across sources, Browser Use covers scraping and form filling, Computer Use reaches local files, and scheduled tasks rerun jobs on their own. The catch has Dia's shape, and bites harder. Fellou meters agent work in Sparks: Free is a 1,000 Spark new-user bonus with 2 scheduled tasks, Plus is $19 a month or $192 a year, which the page puts at $16 a month, Pro is $39.90 a month or $384 a year, at $32 a month, and Ultra is $199.90 a month or $1,920 a year, at $160 a month. The table estimates “Approximately 4 Tasks” for the free bonus, about 8 on Plus and about 20 on Pro, with Ultra's unlimited Sparks marked limited time, then adds that “Actual consumption varies significantly based on workflow complexity.” At least Fellou prints numbers, which Dia does not. Our review records Windows and macOS builds, including Intel Macs, and flags the risk: like any browser agent it can be misled by page content, so supervise it where you are signed in.
Opera Neon · 4.0/5
Best for giving an AI you already pay for a browser.
Opera Neon changes the economics rather than the feature list. Opera made the browser a free download in August 2026, and per our Opera Neon review the free plan keeps Opera's ad blocker and free VPN and adds an MCP connector and the Opera Browser CLI, so a Claude or ChatGPT session you already pay for can drive a real browser without a second AI bill. Dia's free tier has no AI at all. Neon's own agents are the paid part, and the site is blunt: “Subscribe to Neon to activate agentic functionalities and top world LLMs. See everything Neon unlocks for $19.90/month.” Standard is billed month to month and adds Neon Chat, Neon Do for website actions, Neon Make for creation workflows, deep research and the 1-Minute research agent, Tasks and Cards, and full model choice. Our review records Windows 11 and macOS 14 or newer, more ground than Dia covers, plus two cautions: Opera still calls Neon experimental, and Chat, research, Do and Make all sit behind Standard. Choose Neon if you already pay for an assistant and what you actually want is to give it hands.
Gemini in Chrome · 4.2/5
Best for AI inside the browser you already use.
Gemini in Chrome is the least disruptive answer to the problem Dia solves, because it does not ask you to move house. You open it from the Gemini icon in the toolbar, and it uses your open tabs for key takeaways, comparisons and answers, then reaches across Google's apps: finding a flight time in your inbox, checking it in Google Flights and drafting the update. Google's Chrome Help availability article lists no subscription for it. What it does list is conditions, and they matter more than a price would: “Be 13 or older (or the applicable age in your country)”, be in a supported region and language, “Sign in to Chrome”, and use “a Chromebook Plus, Mac, or Windows computer”. Work and school accounts need an administrator to enable it, and “This feature isn't available in Incognito mode.” The agentic piece is the exception: our review records auto browse, which completes tasks such as booking appointments, rolling out first in preview to Google AI Pro and Ultra subscribers in the United States. Against Dia the trade is clean: Dia's assistant reads Slack, Notion and your calendar, Gemini's reads Google's apps, on far more hardware, for nothing.
Arc Search · 4.5/5
Best for AI answers on a phone, same maker.
Arc Search earns a place because it comes from the same company and fills the hole Dia leaves. It is The Browser Company's mobile browser, free on iOS and Android, and its Browse for Me feature sends AI agents to read several sites, then builds one custom answer page with citations, images and follow-up suggestions. Arc's page frames that as “Generate the perfect answer to any question with Browse for Me.” If your complaint about Dia is that it stops at the edge of your desk, this is the same team's phone answer, and at 4.5/5 it ties Comet for the highest score here. Read the status first. Our Arc Search review records the mid-2025 pivot that moved the company's focus to Dia and left Arc and Arc Search in maintenance, with bug fixes but rare new features, and Arc's site now says it out loud: “Arc receives Chromium updates only. For active security patches and enterprise-grade protection, download Dia instead.” The Arc Search page still links to both app stores under a banner reading “Meet Dia, a new AI browser from the makers of Arc”. Use it for what it does today, but do not plan a workflow around it growing.
Which one to pick
- → Comet is the default recommendation here. It does Dia's core trick, an assistant that reads the tabs you already have open, on Mac, Windows, iOS and Android, and it costs nothing
- → Gemini in Chrome if you live in Chrome and Google's apps and want a feature, not a new browser. Check the region, language and account conditions first
- → Opera Neon if you already pay for Claude or ChatGPT. Its free plan hands that subscription a browser through MCP and the CLI, so the agent you already pay for gets somewhere to work at no extra cost
- → Fellou if the job is repetitive multi-step web work you would rather delegate, and a credit meter and a 3.9/5 score are a fair trade for the most ambitious agent here
- → Arc Search if the gap is your phone rather than your desk, with the maintenance caveat above
- → Stay on Dia if you are on an Apple silicon Mac and the answers you need sit in Slack, Notion, your calendar and Google Workspace rather than on the open web. That spread of Slack, Notion and calendar context inside one browser is what you would be giving up, and the 14-day Better Days trial takes no card, so you can settle it before you pay
Other Dia alternatives worth knowing
Well-known options without a full ToolChase review yet, so we give no score and no pricing for them here.
Microsoft Edge Copilot Mode ↗
Microsoft's assistant inside Edge, which its own page describes as working “in your browser, using your tabs to compare options, surface key details, and give clear answers”. Microsoft presents it as free to use, with Microsoft 365 subscribers getting “higher usage limits than free users”.
SigmaOS ↗
A browser built around workspaces, vertical tabs and split screen, with an AI assistant called Airis that chats with the page you are on. Its site says SigmaOS is currently only available on macOS, with iOS and Windows coming soon, so it shares Dia's limit.
Wavebox ↗
A Chromium browser for people juggling many signed-in work accounts, with a built-in assistant called Brainbox on every page that points your preferred AI engine at the tab you are in. Runs on macOS, Windows and Linux.
