ABOUT.

MultiPane is a small set of free tools for using several websites at once. Ask Everywhere sends one question to ChatGPT, Claude, Gemini and others and tiles their windows on your screen. Stream Multi-View plays several YouTube and Twitch streams in one grid. The Workspace shows up to twelve sites side by side in panes. No install and no account.

It started as a sketch: one URL bar on top, a handful of panes below it. Then it ran into a wall every site builder meets — Google, ChatGPT and Claude refuse to load inside another page — so the tools were rebuilt around what actually works.

The tools are honest about their limits. Sites that block framing open in real browser windows instead, and MultiPane tells you when that will happen rather than showing a broken box. The site is supported by ads, which is how it stays free.

What MultiPane is not: a way to inflate YouTube views, a VPN, or a browser replacement. It is for comparing, researching and watching different things at once, in one place.
