YabYab, Yet Another Browser, is a free Mac browser that keeps everything from Arc (tabs down the side, spaces, folders, Split View) and gives your Claude or ChatGPT plan an agent that works in your signed-in tabs.
Edge is Microsoft’s Chromium browser on every desktop and phone, with Copilot built in. Since Copilot Mode was retired in May 2026, its agent, Browse with Copilot, comes with Microsoft 365 Premium in the US.
The short answer
- if you miss Arc and want spaces, pins and folders kept, on a Mac
- if you already pay for Claude or ChatGPT and want it to work in your signed-in tabs
- if you want Claude Code, Codex or Cursor to drive a real browser over MCP
- if you use Microsoft 365 and want Copilot in the browser
- if you want tabs down the side, workspaces, split screen and sleeping tabs built in
- if you work on Windows with Edge set up by your company

Where they differ
What separates them, area by area. Where one plainly has more, it says who; where it comes down to taste, it says so.
AIa matter of taste
Both have an agent that works in your pages. 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. Copilot reads the page, your tabs and history and sums up videos and PDFs; Browse with Copilot scrolls and types in pages for you, signed in, on Microsoft 365 Premium in the US. Yab runs on the Claude or ChatGPT plan you already pay for; the other on its own AI.
Agents like Claude Code and Codexeven
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. Edge can be driven over MCP and a command line, through Microsoft’s Playwright MCP, which can launch Edge or attach to your running Edge.
Tabs and windowsYab leads
Yab has tabs down the side, spaces, Split View, folders in the sidebar and tabs that sleep. Edge has tabs down the side as a setting, spaces, Split View, folders in the sidebar and tabs that sleep.
Priceeven
Yab: Free; its AI runs on your own Claude or ChatGPT plan. Edge: Free, with Copilot; Browse with Copilot needs Microsoft 365 Premium $19.99/month (US).
Where it runsEdge leads
Yab runs on Mac. Edge runs on Mac, Windows, Linux, iPhone and Android. On a Mac, Yab needs macOS 15.4 or later and Edge needs macOS 13 or later. Yab has no phone app yet. On the phone, Edge: iPhone, iPad and Android; syncs tabs, favorites, passwords and history.
Engine and extensionsa matter of taste
Yab is built on WebKit, the engine Safari uses; Edge on Chromium, as Chrome is. Both take extensions from the Chrome Web Store.
Privacyeven
Yab has an ad blocker built in. 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. Edge has a VPN. Copilot may use your question, the page, your open tabs and history; Browse with Copilot keeps screenshots up to 30 days, not for training, Microsoft says.
Where Edge is better
Edge comes out ahead on where it runs. It is also the better pick if you:
- Use Microsoft 365 and want Copilot in the browser
- Want tabs down the side, workspaces, split screen and sleeping tabs built in
- Work on Windows with Edge set up by your company
The catch with each
Real limits, from the makers’ own words and our own use.
Microsoft Edge
- Browse with Copilot needs Microsoft 365 Premium ($19.99 a month) and is US only
- Copilot reads pages, tabs and history unless you turn it off
- Workspaces lost sharing in 2026, and Collections were removed
- No ad blocker of its own
Yab, honestly
- Mac only: macOS 15.4 or later, no Windows, iPhone or Android
- New: first released in September 2026
- Its AI needs a Claude or ChatGPT plan; ChatGPT’s free plan may work with low limits
- WebKit, as in Safari: a site tested only in Chrome can misbehave
- Closed source
