What is 1SO SearchHub
One input, search everywhere - AI and multi-engine search tool 1SO SearchHub is a Chrome extension for searching several engines at once. Type a query once, tick the engines you want to ask, and it opens all of their result pages in a single action — grouped into one colored tab group and listed in the side panel, so you can compare answers instead of copy-pasting the same question into five different sites.
Useful whenever one source is not enough: check what an AI search engine, an AI chat assistant, a classic search engine, and a social platform each say about the same topic.
KEY FEATURES:
* One query, many result pages Dozens of preset engines in 9 categories — AI search, AI chat, classic search engines, social media, video, maps, developer sites, shopping, and knowledge bases. The full list is visible inside the extension, and you can pick as many as you want for each search.
* Results grouped automatically Every tab from a search lands in one tab group with a color label, so a batch of results never dissolves into an anonymous row of favicons.
* Vertical tabs in the side panel The side panel opens automatically after a search and lists the new tabs vertically, ready to click through one by one.

* Quick combos Four built-in sets — All AI, Chinese AI, Traditional Search, Look Me Up — each fires a fixed batch of engines in one click. Save up to 5 of your own.
* Right-click a selection Select any text on any page and search it from the context menu, without going back to the search box.
* Keyboard shortcuts Alt+S opens the search panel; Alt+Q searches the current selection.
* Custom engines Add any website to the list with your own URL pattern.
* Interface Chinese / English UI. Dark and light theme follow your system setting.
HOW TO USE:
1. After installing, click the toolbar icon or press Alt+S to open the panel. 2. Type a query, tick the engines (or pick a quick combo), press Enter. 3. Results arrive as one tab group and appear in the side panel — compare them there. 4. Hit an unfamiliar term while reading: select it, right-click, "Search with 1SO SearchHub", or press Alt+Q. 5. In Settings you can add custom engines, save your own combos, and switch language and theme.
