Aside vs Edge

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

Aside is an AI agent browser from a Y Combinator startup, on Chromium, for Mac and Windows. Its agent does multi-step work in the sites you are signed in to, on Aside’s own models or your ChatGPT or Claude plan.

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.

Pick Aside
  • if you want an agent for multi-step work across your signed-in sites, on Mac or Windows
  • if you want a free plan with AI credits, or to bring your ChatGPT or Claude plan

Pick Edge

Or Yabours
  • if you miss Arc and want spaces, pins and folders kept, on a Mac

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. Aside’s agent runs multi-step tasks in your signed-in sites, signs in from its own password vault without seeing the passwords, and asks before payments, posts and messages. 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 Codexeven

Aside can be driven over MCP and a command line, through the aside command line, with aside mcp as its MCP server. 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 windowsAside leads

Aside 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

Aside: Free with 500 AI credits a month; Pro $20/month; Max $200/month; or your own ChatGPT or Claude plan. Edge: Free, with Copilot; Browse with Copilot needs Microsoft 365 Premium $19.99/month (US).

Where it runsEdge leads

Aside runs on Mac and Windows. Edge runs on Mac, Windows, Linux, iPhone and Android. On a Mac, Aside needs macOS 15 or later and Edge needs macOS 13 or later. Aside has no phone app yet: an iPhone app is in the works. Pro runs its agent from Slack or Telegram. 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

Aside has an ad blocker built in. Aside keeps task transcripts and files on your Mac; model providers get the prompts, page snapshots and screenshots a task needs, and analytics sharing is on by default. 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.
