Arc browser alternative: what maps to what in Minda, and what does not

Why are people looking for an Arc alternative?

Because Arc is maintained but no longer developed as it was. In a letter to Arc members in May 2025, The Browser Company said it is not actively developing Arc’s core experience the way it used to, while it keeps maintaining Arc, and Arc’s home page calls Dia the next evolution of Arc. Arc itself runs on Windows and macOS (its FAQ says Linux is not supported) and is built on Chromium, the engine of Chrome and Edge.

So the useful question is less "what looks like Arc" than "what keeps what I liked, and adds what I need now". This page answers it for Minda Super Intelligence, which is not a browser but the personal AI agent app for your computer, with a built-in Chromium browser that its SI agent works in. Every Arc fact here was read on Arc’s own pages on 2026-10-18, and AI browsers compared sets Arc beside Minda function by function.

What maps to what?

Arc’s column is what its own pages say; Minda’s column is from Minda’s facts file. Where one side has nothing to match, the note says so, and three rows go to Arc.

How do Arc’s Spaces become workspaces?

A workspace in Minda keeps its own cookies and sign-ins, apart from the others, and you can have as many as you like on every plan. If you used Spaces to split work from home, make a workspace for each; if you used them for clients, make one per client, and each stays signed in to its own accounts, even two accounts of the same site at once. Workspaces sit on the left rail with your pinned apps, and a private window keeps its cookies in memory only.

The difference that matters most is the SI agent. It works in whichever workspace you name ("in the Client B workspace"), with that workspace’s sign-ins and out of your sight, and "every account" sends helpers into each workspace side by side. Only your own words pick a workspace, never text on a web page, and a schedule or a saved agent keeps the workspace it was made in. Two accounts of one site at once walks through the set-up, and separate workspaces has the feature page.

How do I bring my Arc data over?

1. Open Settings → Import & export → Import from another browser; on the first run, the Bring your stuff step offers the same import.
2. Pick Arc and its profile. Minda finds Arc in its app folder on Windows and in its usual folder on macOS, and proposes the profiles used in the last 30 days.
3. Tick what to bring: bookmarks, history, passwords, sign-ins to sites (cookies), extensions and open tabs.
4. Press Import. Each kind reports what came over, what was skipped and why; Stop ends it, and Try again repeats only the kinds that need it.
5. If some passwords stay behind, the result says how many and offers Use a passwords file: a CSV export from the browser, which Minda saves encrypted and then offers to delete for good.
6. Keep Arc installed until you are sure: the import reads copies of Arc’s files and removes nothing from Arc.

What does Arc do that Minda does not?

Three things, stated plainly, so you can decide with them in view.

• Every Chrome extension. Arc’s FAQ says it supports every extension Chrome supports. In Minda many Chrome extensions work, not every one, so test the few you rely on in your first hour.
• A phone browser. Arc Search is a separate browser for iOS and Android, and its Browse for Me searches, reads pages and writes you an answer page. Minda on your phone is the account page, with the inbox, tasks, notes and bookmarks of your computers; it is not a phone browser, and there is no Minda phone app to install.
• Public downloads. Arc has public downloads for Windows and macOS. Minda Super Intelligence for Windows 10 and 11 (64-bit) is coming soon; macOS and Linux builds are not published yet.

What does Minda add that Arc’s pages do not list?

• An SI agent that acts. It opens pages, clicks, types and fills forms in your own signed-in accounts, in hidden tabs, and stops for your OK before anything that pays (Ask before paying, on by default). Arc’s desktop pages describe no agent that acts on pages.
• Schedules and automations. Unlimited scheduled tasks, scrapes and rules on every plan, and cloud automations that run while your computer is off, 20 turned on at once on Free. Arc’s pages list no scheduled tasks.
• Any AI model. Minda’s hosted models on credits, your own OpenAI, Claude, Gemini, DeepSeek, OpenRouter or Qwen key, or Ollama on your computer at no credits; Keep SI on this computer refuses every cloud provider before anything is sent.
• Split view and vertical tabs. Vertical tabs, tab groups and split view up to a four-pane grid on every plan, with Memory Saver for idle tabs and every window back as it was after a restart.
• Several accounts of one site at once. One workspace per account, all signed in side by side, and the agent works in the one you name.

Arc, Dia or Minda: which fits what you do?

Stay on Arc if it does what you need and a browser that is maintained rather than developed suits you. Look at Dia if you want The Browser Company’s next browser; Minda vs Dia sets the two side by side, each fact sourced and dated. Choose Minda Super Intelligence if what you want is an agent that does the work in your own accounts, with workspaces that keep each account apart.

Minda is free to start: the Free plan has every function, the SI agent on pages included, with 100 Minda AI credits a month and 30 free everyday replies a day, and your own AI keys or Ollama cost no credits. Pro differs by credits, never by functions; pricing has the table.
