Key Entity Extraction
Automatically identifies and highlights dates, names, monetary amounts, and critical metrics from the document.

Frequently Asked Questions
What types of documents work best?
Digital PDFs with selectable text work best — reports, articles, contracts, research papers. Scanned PDFs need OCR (Pro plan).
How is the summary generated?
Text is extracted using PDF.js, then processed by an AI model. Without an AI key, a smart extractive algorithm selects and ranks the most important sentences.
Is there a document length limit?
The summarizer processes up to 10,000 characters (approximately 5–7 pages). Longer documents are automatically truncated to the most content-rich section.
What does Advanced mode do differently?
Advanced mode detects the document type (invoice, contract, report, etc.) and structures the summary accordingly, plus extracts key entities like dates, names, and amounts.
About this tool
VisualDocs's AI Summarizer uses PDF.js for text extraction and an edge function that calls GPT-4o-mini (or falls back to extractive ranking) to generate structured summaries with automatic document type detection.
