AI Search & Smart Ctrl+F for Any Webpage or PDF | ctrlQuery 是什麼

Chrome 商店介紹

AI search for any webpage or PDF. Find what you mean, not just what you type. Semantic, on-device, no account needed. Search the web the way you think.

ctrlQuery is AI search for any webpage or PDF. Instead of matching the exact word like Ctrl+F, it reads the page and surfaces the passages that match your meaning, even when the page uses completely different wording. Type a question, a phrase, or a plain keyword, and ctrlQuery jumps you straight to the part that matters.

It also includes a fully upgraded keyword search that does everything Ctrl+F can't.

━ SMART SEARCH (AI search, paid) ━

Ask a question or describe what you are looking for. ctrlQuery embeds the page on-device and returns the passages that match your meaning, not just your exact wording. This is semantic search that runs entirely in your browser.

Examples that work:

展開其餘商店介紹▾

"is the dairy free?" on a recipe page
"how do I cancel my subscription?" on a help center that only says "deactivate account"
"is there water?" on a Wikipedia article about Mars
"how do I add an element to the end of an array?" on MDN docs
"what triggered World War I?" on a long Wikipedia article

If you have ever scanned a 10,000-word policy doc, a long Reddit thread, or a documentation site looking for the right paragraph, AI search jumps you straight to it. No more rephrasing your query five times.

━ KEYWORD SEARCH (free, forever) ━

A drop-in replacement for Ctrl+F with everything Chrome's built-in search forgot:

Match Case and Whole Word toggles
OR clauses with color-coded per-term highlights
Slash commands like /date, /email, /phone, /price, /number, /links that highlight every match of that pattern on the page in one tap
Finds matches inside hidden content like collapsed dropdowns and lazy-loaded sections, which plain Ctrl+F skips entirely

If you have ever needed Ctrl+F to do more than match a literal string, keyword mode handles all of it for free.

━ WHY YOU'LL WANT IT ━

Ctrl+F finds the exact word you typed. Smart Search finds the answer. ctrlQuery is the AI Ctrl+F alternative for people who read long pages: researchers, developers, students, and anyone who lives in documentation, contracts, and PDFs.

━ WHAT MAKES IT DIFFERENT ━

▸ ON-DEVICE BY DEFAULT The AI model runs entirely on your device. Your queries and the page text never leave your browser. No API keys, no accounts, no telemetry.

▸ WORKS OFFLINE Once the model is cached, AI search works on a plane, on the subway, anywhere. No internet required.

▸ WORKS ON PDFS A built-in PDF viewer brings the same semantic search and keyword search to PDF files, so you can search a PDF by meaning, not just by exact text.

▸ NO SUBSCRIPTION Smart Search is a $3.99 one-time unlock. Pay once, yours forever, on every device you log into. Keyword search and everything else stays free.

━ PRIVACY ━

ctrlQuery only reads the page you actively search, and only when you ask. Nothing is logged, transmitted, or sold. Search indexes live in your browser's local storage and disappear when you uninstall.
