Files stay private: PDFs and images are edited in your browser.
Grounded in the file
Summaries use the text extracted from your open PDF, so the briefing tracks what is actually on the page — not a generic template.
Beside the document
Ask AI sits in the editor: keep reading the page while the summary appears, then edit or export without leaving the session.
Scans after OCR
Image-only pages need a text layer first. Run OCR, then summarize — the same flow as editing scanned contracts.
Summarize in the real Ask AI panel
Not a fake chat on the page — the same right-hand bubble, chips, and multicolor loader as in the product.
Summarize while you read
Drop a PDF, open Ask AI, tap Summarize. The thinking state uses the brand rainbow shimmer.
One-tap chips
Summarize, key points, or a PDF brief — same labels as the editor empty state.
Scans need OCR first
Image-only pages need a text layer before Ask AI can read them.
Briefing ready
The answer appears in the bubble — then jump to Highlight or Edit text on the same page.
A briefing instead of a reread
Long contracts, board packs and research PDFs bury the decision in the middle. An AI summary surfaces parties, dates, obligations and open questions so you know where to click next.
Because it runs inside WindPDF, you can jump from the summary back to Edit text, Highlight or Redact without uploading the file a second time.

Frequently asked questions
Run OCR first so the page has extractable text. Then Summarize can read the layer and produce a briefing.
Treat it as a draft. AI can miss nuance or invent details — verify critical dates and amounts against the source pages.
