AI PDF Summarizer — Browser-side Extraction + GPT

Drop a PDF — text is extracted entirely in your browser via PDF.js, then sent to GPT-4o-mini for a structured summary. The PDF itself never leaves your machine; only the extracted text is sent to OpenAI.

OpenAI API Key

Your key is stored only in your browser (localStorage) and sent directly to the provider. We have no backend, so it never touches our servers. Get an OpenAI API key.

Scanned PDFs: use the OCR tool first

Image-based PDFs (scans, photos of pages) contain no extractable text — PDF.js will return nothing for them. Use the Image-to-Text OCR tool on each page first, then paste the OCR output into something like the Paragraph Rewriter or Essay Writer for summarization.
