No — parsing and search run locally in your browser with PDF.js, so the document never leaves your device. There are no cloud calls and no credits involved — the tool has no AI-provider buttons.
Native-text PDFs under ~500 pages: course books, manuals, contracts. Scanned image-only PDFs answer poorly until OCRed — extract text first, then chat. Heavy tables and two-column layouts may quote out of order, so verify numbers against the page.
Parsing and search work fully offline once the page loads, since everything runs locally. Your chat history stays in the browser session and clears when you close the tab.
Query words of 2 or fewer letters plus a stop-word list are dropped; each paragraph split on blank lines is kept only if longer than 20 characters, else sentences longer than 10 characters are used. Each chunk scores matched divided by keywords with confidence rounded to a percent; the meter colors 70 percent and up green, 40 and up amber, below red. Example: 3 of 4 keywords matched gives 75 percent green. Show Text previews only the first 500 characters.
