What it looks like

One box, 50 engines. Tick what you want — they all open at once, grouped, and listed in the side panel.

1SO panel: search box, quick combos and 50 engines sorted into 9 categories
The panel: one box + 50 engines, tick whoever you want to ask
Side panel listing this search's results vertically, grouped
The side panel: results from this search, listed vertically
What happens after you hit search
  • Tick 3 engines → 3 result pages open at once
  • They land in one colored tab group, not mixed with your other tabs
  • The side panel lists them vertically — click through to compare
  • Select text → right-click or Alt+Q to re-run with your default combo

Install it, and tabs stop getting messy

The web version can already open several results at once. With the extension they land in one colored tab group, the side panel manages them, and you also get right-click and keyboard search.

Detecting your browser…

One moment

Manual install (any Chromium browser, about a minute)
  1. Download the extension zip above and unzip it somewhere permanent.
  2. Open your extension manager: Chrome / Edge chrome://extensions · Edge edge://extensions · 360 se://extensions · QQ: menu → App center.
  3. Turn on Developer mode (top right).
  4. Click Load unpacked and pick the folder from step 1 (the one containing manifest.json).
  5. Click the toolbar icon, or press Alt+S.

Opening tabs is the shell. Comparing is the point.

Different AIs disagree all the time. Put them side by side instead of refreshing one by one.

50 engines, 9 categories

AI search, AI chat, classic search, social, video, maps, dev, shopping, knowledge — tick as many as you like.

Tabs group themselves

One search → one colored tab group. Your existing tabs stay exactly where they were.

Select to search

See a word you don't know? Select it → right-click or Alt+Q → it runs your default combo.

One honest note about the web version

Browsers block opening several windows at once. So the web version tries to open them all and lists whatever got blocked as links — one click each to finish. The extension isn't limited: it creates tabs directly inside the browser, which is why "one click, all open" really needs it.
