PDF Brief is an AI PDF summarizer for understanding long documents. Upload a text-based PDF for a free preview with an overview and key points, then unlock a full analysis when you need a deeper read.
Built for reports, research papers, manuals, policies, e-books, and long articles, PDF Brief identifies the central argument, major findings, important figures, stated risks, and sections that change the conclusion.
Use PDF Brief to prepare for a research review, understand a report before a meeting, extract main points from a policy, organize study material, or get a useful first pass through a long manual. It provides a consistent analysis workflow without complex prompts or manually splitting a long PDF into pieces.
Free previews are available daily. For deeper analysis, buy a one-time pack of 3 full document analyses for $2.90—these never expire—or choose a Pro subscription for unlimited full analyses. Failed analyses do not consume a credit.
PDF Brief works with text-based PDFs. Scanned or image-only PDFs without a usable text layer, visual page layouts, and table structure are not reliably analyzed today. Results are assistive reading notes, not legal, medical, financial, or other professional advice.
