How AI PDF Chat Works

  1. In-Browser Text Extraction: PDF files are parsed page-by-page directly inside your browser memory using PDF.js. Scanned pages are normalized into searchable text.
  2. Semantic Indexing: The document is segmented into semantic passages with exact page coordinate tracking.
  3. Question Answering: When you ask a question, the retrieval engine searches indexed passages for high-relevance matches and synthesizes an answer directly from the text.
  4. Clickable Page Citations: Every assertion includes a clickable badge (e.g. [Page 4]). Clicking it opens the exact source excerpt for verification.
  5. Strict Truthfulness: If your document does not contain the answer, the tool explicitly alerts you rather than inventing false facts.
