DuoSou

One Query. Multiple Searches.

Free · Designed for iPad. Not verified for macOS.

DuoSou is a privacy-first multi-site query tool. Enter a query once, then open it on the public sites you choose. It is not a new search engine and not an AI search app. DuoSou builds public search URLs on your device and opens external services. There is no AI involved, and it does not scrape websites. WHY DUOSOU • Free, no sign-in — ready to use, no account required • Privacy respected — searches are not recorded by default, and DuoSou never uses AI to analyze your search data • You're in control — you decide where to search WHAT YOU CAN DO • Save search profiles (web, shopping, news, discussion, or your own mix) • Search all selected sites together • Filter by time, excluded words, and file type where the destination supports it • Save favorites and optional on-device history • Lock the app with a 4-digit PIN PRIVACY By default, DuoSou does not save your search content. If you turn history on, keywords stay only on this device (up to 30). Favorites, custom profiles, custom sources, and app lock data also stay on this device. DuoSou does not use analytics and does not send your query to ads as a custom targeting parameter. When you open Google or another site, that service receives the request according to its own rules. DuoSou does not claim searches are completely anonymous. The app is free and supported by ads (Google AdMob).
