YabMove from Comet to Yab.
Yab brings Comet’s pinned and open tabs, passwords, cards, bookmarks, history, extensions and your sign-ins, from every profile.
Yab reads it straight from Comet’s files on your Mac. Nothing goes through a server, and Comet can stay open.

What changes after Comet
Yab next to Comet, area by area. The full comparison has the table and sources.
AIa matter of taste
Both have an agent that works in your pages. Comet’s assistant answers about pages and open tabs and can click, fill forms and navigate for you, asking before it acts. Yab’s agent works in tabs of its own beside yours, signed in as you, on your Claude or ChatGPT plan; Send, Pay and Delete wait for your yes. Yab runs on the Claude or ChatGPT plan you already pay for; the other on its own AI.
Agents like Claude Code and CodexYab leads
Comet has no MCP server or command line for outside agents. Yab can be driven over MCP and a command line, through yab mcp and the yab command, for Claude Code, Codex, Cursor and any MCP client.
Tabs and windowsYab leads

Where it runsComet leads
Comet runs on Mac, Windows, iPhone and Android. Yab runs on Mac. On a Mac, Comet needs macOS 13 or later and Yab needs macOS 15.4 or later. On the phone, Comet: iPhone, iPad and Android; on iPhone it syncs bookmarks and history with desktop Comet. Yab has no phone app yet.
Engine and extensionsa matter of taste
Comet is built on Chromium, as Chrome is; Yab on WebKit, the engine Safari uses. Both take extensions from the Chrome Web Store.
Privacyeven
Both have an ad blocker built in. Comet keeps history, cookies and passwords on your device unless you sync; the assistant sends the page it needs to Perplexity, kept up to 30 days. Yab has no account and no server of ours between you and your sites; what your agent reads goes to Anthropic or OpenAI under your account.
Questions
Does moving change anything in Comet?
No. Yab only reads Comet’s files. Comet keeps everything, and you can go on using both.
Do I have to close Comet first?
No. Yab reads Comet’s files while it is open.
Will I stay signed in to my sites?
Mostly. Your sign-ins come with the rest, so most sites open signed in. A few ask you to sign in again.
Do my extensions come?
Yes. Yab fetches each one you had switched on fresh from the Chrome Web Store and runs it on WebKit, the engine Safari uses. Most work as in Chrome; what an extension kept itself, like its own sign-in, stays in the old browser.
Can I bring it in again later?
Yes, any time, from Settings › General › Bring in from another browser.
What does Yab cost?
Nothing. Its AI runs on the Claude or ChatGPT plan you already pay for, if you connect one.
Yab, Yet Another Browser.
Free for the Mac. Arc’s sidebar, your own Claude or ChatGPT as the agent, Chrome extensions on WebKit.
