How AI PDF Chat Works

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.
Semantic Indexing: The document is segmented into semantic passages with exact page coordinate tracking.
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.
Clickable Page Citations: Every assertion includes a clickable badge (e.g. [Page 4]). Clicking it opens the exact source excerpt for verification.
Strict Truthfulness: If your document does not contain the answer, the tool explicitly alerts you rather than inventing false facts.

How to Use AI PDF Chat & Document Question Answering

Step 1
Upload one or more PDF documents (up to 100MB and 200 pages).
Step 2
The engine extracts text page-by-page, builds a semantic passage index, and creates an instant executive summary.
Step 3
Type your question in the chat bar, or select from suggested starter prompts.
Step 4
Read the synthesized answer, click page reference chips to view source excerpts in the inspector, and export your transcript to TXT.

Tips before you start

Use the clearest source file or text you have, especially when quality or formatting matters. Try the default result first, then adjust settings only if you need a different output.

For privacy, prefer tools that can stay in the browser when possible, and avoid uploading highly confidential material to any web app.
