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

What changes after Dia
Yab next to Dia, area by area. The full comparison has the table and sources.
AIYab leads
Only Yab has an agent that clicks, types and finishes tasks in your pages. Dia chats with your tabs and the tools you connect, like Gmail, Slack and Notion, and drafts mail and invites; there is no documented agent that works through sites. 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
Dia 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
Dia has tabs down the side as a setting, spaces, Split View, folders in the sidebar and tabs that sleep. Yab has tabs down the side, spaces, Split View, folders in the sidebar and tabs that sleep.
PriceYab leads
Dia: Browser free; AI on Better Answers $20/month or Better Days $100/month. Yab: Free; its AI runs on your own Claude or ChatGPT plan.
Where it runsDia leads
Dia runs on Mac and Windows. Yab runs on Mac. On a Mac, Dia needs macOS 14 or later and Yab needs macOS 15.4 or later. Dia has no phone app. Yab has no phone app yet.
Engine and extensionsa matter of taste
Dia 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. Dia’s chat goes through its servers to Anthropic, OpenAI and Google; chats and history stay on your Mac, and content sharing is on by default, kept 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 Dia?
No. Yab only reads Dia’s files. Dia keeps everything, and you can go on using both.
Do I have to close Dia first?
No. Yab reads Dia’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.
