Most people use a fraction of what search engines can do. Sirch is the query builder that unlocks the rest. Instead of guessing at syntax, you build advanced search queries one operator at a time — site:, filetype:, intitle:, exact "phrases", exclusions, OR groups, and more — with a live preview of exactly what will run. When you're ready, launch straight into the search engine and browser of your choice. WHO IT'S FOR For people who search for a living — and people who search for the thrill of it. Researchers, journalists, OSINT analysts, developers, students, and every curious mind who'd rather explore ten engines than settle for one. When "close enough" isn't good enough, Sirch gets you to the exact page. BUILD QUERIES VISUALLY • Structured editor — every operator and term is its own editable row • Every operator your target supports, in one picker — the complete set for each search engine and platform, not just the common ones • Operator picker with plain-language descriptions and live examples • Exact-phrase, exclude, OR, and grouping support • Live preview of the full query as you build it • Advanced raw-text mode when you want total control UNDERSTAND EVERY OPERATOR • Explain mode breaks your query down in plain language • See what each operator does before you run it • Operators are tuned to your target — the search engine you pick (Google, Bing, DuckDuckGo, Brave, and more) or a platform like Reddit, YouTube, GitHub, X, LinkedIn, Stack Overflow, or Bluesky. Switch targets and the set updates instantly FILTER RESULTS YOUR WAY • Fine-tune each engine's results — Sirch adds the right URL parameters for you, no settings menus • Set your region and language to see results as they'd appear anywhere in the world • Limit by time — past hour, day, week, month or year • Choose your result type — web, images, news, videos, shopping, forums, books, even AI Mode — deepest on Google, plus verticals on Qwant, Startpage, and Mojeek • Every engine brings its own controls too: SafeSearch, country restrict, result-page depth, even Marginalia's curated indexes • Platforms get their own result-page filters as well — sort Reddit by Hot, Top, or New; filter YouTube by upload date, duration, or type; jump into GitHub code search; switch X between Top and Latest, and more LAUNCH ANYWHERE • 20 search engines — Google, Bing, DuckDuckGo, Brave, Qwant, Mojeek, Ecosia, StartPage, and 12 more • Open in any browser installed on your device, or open the same query across every browser • Jump straight into the native YouTube, X, and Google apps — skip the browser entirely BUILT FOR EVERY APPLE DEVICE • Designed for iPhone, with full iPad layouts that use every inch of the screen • Runs as a native Mac app — build and launch queries right from your desktop (on Mac, queries open in Safari or your default browser; set any browser as your macOS default to launch straight into it) • Full hardware-keyboard support on iPad and Mac — a ⌘K command palette to jump to any engine, operator, or action, plus shortcuts to launch, copy, save, and switch engines with ⌘1–9 • Light, dark, and automatic themes • Choose which engines and platforms show up as your quick-launch targets SAVE, SYNC, AND ORGANIZE • Everything lives on your device first — save queries, group them into folders, and keep a full search history with timestamps • Automatic iCloud sync keeps your saved queries and history in step across every iPhone, iPad, and Mac on the same Apple ID • No separate account to create — your iCloud handles it, privately PRIVATE BY DESIGN • No sign-up, no login, no profile • Your searches are never tracked, logged, or sold • Your data stays on your devices and in your own iCloud — never on our servers • Sync runs entirely through Apple's private iCloud, not a third party Find what you're actually looking for. Build the query, understand it, and launch it. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
