Tabbit vs Edge

We make Yab, the third column.facts checked Oct 9 ↓

Tabbit is a free Chromium AI browser for Mac and Windows from Lumina Lab in Singapore, with chat, an agent mode and a choice of many vendors’ models.

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

Pick Tabbit

if you want a free agent browser with a wide choice of models, Chinese ones included
if you want the same AI browser on Windows and Mac
if you want Codex or Claude Code to use your signed-in sessions through its command line

Pick Edge

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

Or Yabours

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

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. Tabbit chats with your tabs, files and screenshots, and its agent mode runs multi-step tasks in tab groups of its own, on GPT, Claude, Gemini, DeepSeek, Kimi, Qwen or GLM. 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.

Agents like Claude Code and CodexEdge leads

Tabbit can be driven over a command line, through the Tabbit command line, with a skill for Codex, Claude Code and Cursor. 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 windowseven

Tabbit has tabs down the side, Split View and folders in the sidebar. Edge has tabs down the side as a setting, spaces, Split View, folders in the sidebar and tabs that sleep.

Priceeven

Tabbit: Free with a weekly AI allowance; Pro $30/month. Edge: Free, with Copilot; Browse with Copilot needs Microsoft 365 Premium $19.99/month (US).

Where it runsEdge leads

Tabbit runs on Mac and Windows. Edge runs on Mac, Windows, Linux, iPhone and Android. On a Mac, Tabbit needs macOS 13 or later and Edge needs macOS 13 or later. On the phone, Tabbit: only for its Chinese edition, in Chinese; tabbit.ai lists mobile as planned. On the phone, Edge: iPhone, iPad and Android; syncs tabs, favorites, passwords and history.

Engine and extensionsa matter of taste

Both are built on Chromium, as Chrome is, so sites work as they do in Chrome. Both take extensions from the Chrome Web Store.

Privacyeven

Tabbit has an ad blocker built in. Tabbit sends prompts and pages you share to the model vendor you pick, on servers in Singapore or your region; its maker says it doesn’t train on your data. 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.

What their pages don’t lead with

The free AI is a weekly allowance, larger only if Tabbit is your default browser
No Linux or phone apps yet
No MCP server documented, only its command line

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
