1. Dia

SituationalPeople who want accurate, sourced answers across their tabs and quick slide decks, and prefer an assistant that asks before it acts
6.3/10

Dia is a Chromium-based web browser with a built-in AI assistant, made by The Browser Company of New York, the startup behind the Arc browser. The assistant lives in the address bar and a side chat: it can answer questions about open tabs, summarize pages, videos and files, compare several tabs, draft text, and build reports and slide decks. It also connects to work apps such as Slack, Gmail, Google Calendar, Notion, Microsoft 365, Atlassian, GitHub, Figma, Zoom and Loom so answers can draw on that data.

Dia is the most careful AI browser we have tested: it asks before it reads or opens anything, got every research task right and built a real, sourced slide deck. But it cannot click or type, so forms, purchases and scheduled routines are out of reach.

Read the full Dia review 8 scripted tasks, timings, 13 screenshots, pricing and FAQ
  • All three research tasks correct, including opening three Wikipedia tabs on request
  • Built a real five-slide deck with a Present mode and sources, after asking two sensible questions
  • Asks permission before reading a website or opening tabs, with Allow once, Always for this chat or Deny
  • No admin prompt, no services, no hidden accounts; uninstalls cleanly in under two seconds
  • Honest about its limits: says plainly when it cannot fill a form or buy something
  • Cannot type into fields, click buttons or submit forms, so both form tasks failed
  • Cannot create scheduled routines
  • Onboarding pre-ticks content-data sharing, default browser, taskbar pin, start at login and a seven-day default trial
  • Adds a firewall rule that allows outbound traffic for any program, not just Dia
  • Large install: 1.49 GB on disk
  • Sign-up asks for a work email before you can browse

2. Strawberry

SituationalHands-on users who want a browser agent for research, form filling and data gathering and are comfortable reviewing what it installs
6.2/10

Strawberry is a complete desktop browser, with tabs, bookmarks, profiles, saved passwords, extensions and import from other browsers, that has AI companions built into the browsing workflow. A companion can read what is on screen, answer questions, operate web pages, use connected apps and create files.

Strawberry got seven of our eight scripted tasks fully right, from quick web research to a sourced slide deck, but it installs two hidden Windows user accounts that stay behind after you uninstall it, uses about twice the memory of Edge and clicked “Add to basket” without asking. Capable agent, worrying footprint.

Read the full Strawberry review 8 scripted tasks, timings, 19 screenshots, pricing and FAQ
  • Did 7 of our 8 scripted tasks in full: five web tasks in under a minute each (29–52 s), a sourced slide deck and an 11-field tricky form
  • Works in real, visible browser tabs and keeps a step-by-step trace you can expand and review
  • Reports honestly: it said "no order was placed" and "not stated" instead of inventing results
  • Answers arrive as clean tables with Copy and Export buttons
  • The Free plan was enough for our whole test: 48 credits used, no card asked
  • Creates two enabled local Windows accounts (StrawberrySbxOffline/Online) via an admin "sandbox helper" and does not remove them on uninstall
  • Filled in the tester’s name, job title, company and city during onboarding without being given them
  • Heavy on memory: 5.3 GB for ten tabs against 2.4 GB in Edge on the same PC, and 1.7 s to open a window against 0.7 s
  • About 565 MB of data and cached installer left on disk after uninstalling, and the uninstaller offers no option to delete your data
  • Long onboarding (about nine screens) with nudges to import your browser and give a five-minute interview
  • Treated “buy it” as permission to act: it clicked “Add to basket” without asking first

3. Comet

SituationalPeople who want a normal Chromium browser with a fast built-in answer panel, and do not need the AI to act on web pages for them
5.2/10

Comet is a free web browser from Perplexity, the AI search company. It is built on Chromium, the same engine as Chrome and Edge, so sites, bookmarks, passwords and most Chrome extensions work as you would expect. Perplexity is the default search engine, and an AI Assistant in a side panel can read the page you are on, your open tabs and your browsing history to answer questions with sources.

On the Free plan Comet is a fast, well-behaved Chromium browser with a quick answer panel, but not an agent: in eight scripted web tasks its Assistant never once clicked, typed or opened a tab, and every answer pointed us to Perplexity's separate Computer agent instead.

Read the full Comet review 8 scripted tasks, timings, 16 screenshots, pricing and FAQ
  • Answers arrive in 2–5 seconds and cite their sources
  • Light on memory for an AI browser: 3.0 GB for our ten test tabs, against 5.3 GB for Strawberry and 2.4 GB for Edge
  • Sign-in is optional, and the uninstaller offers to delete your browsing data
  • No hidden Windows accounts; the main app is signed by Perplexity AI, Inc.
  • Honest when it cannot do something, including “nothing was created”
  • On the Free plan the Assistant would not fill a form, open tabs, create a routine or add to a basket
  • Slide decks need Pro: on the Free plan it wrote the outline as chat text and showed an upgrade card
  • Every answer carries a prompt to run the task in Perplexity’s Computer agent instead
  • Got the current Firefox version wrong (one release behind)
  • Installs for the whole PC with admin rights and three Windows services; two updater services stay after uninstalling
  • The uninstaller itself is unsigned, so Windows shows “Publisher: Unknown”
  • Pushes hard to become your default browser, including an “Are you sure you want to browse with ads?” prompt

What AI browsers cost for your team

Cheapest paid plan × seats × 12, at list price. Annual discounts and volume deals not included. Comet, Dia, and Strawberry also have a free plan.

How we test AI browsers

  1. T1Install from the official site and reach the first agent task; count steps, prompts and minutes, and note anything installed outside the browser.
  2. T2Run the same 8 scripted tasks on a free test account, pasted word for word: five core web tasks (research from official sources, a form fill, a price comparison, a multi-tab extraction and a scheduled routine), a request to buy a book on a demo shop, a five-slide deck and a tricky multi-step form. Each is scored as done, partly done or failed, with time and credits used.
  3. T3Check what the agent may do without asking: purchases, sending messages, entering passwords, and whether every action can be reviewed afterwards.
  4. T4Measure cold start, idle and under-load RAM/CPU against Microsoft Edge on the same 10 tabs.
  5. T5Check where chats and page data are processed and stored, training opt-outs, and what is left behind after uninstalling.

Our final verdict

Dia has the highest score in our tests, 6.3/10.

None of the AI browsers we tested has earned an outright recommendation yet, so pick the one that fits what you need:

  • Dia (6.3/10) is best for people who want accurate, sourced answers across their tabs and quick slide decks, and prefer an assistant that asks before it acts.
  • Strawberry (6.2/10) is best for hands-on users who want a browser agent for research, form filling and data gathering and are comfortable reviewing what it installs.
  • Comet (5.2/10) is best for people who want a normal Chromium browser with a fast built-in answer panel, and do not need the AI to act on web pages for them.
