Four simple steps. No servers, no API keys—just quick, private summaries.
Click “Select PDF” and choose the document. Pages are parsed locally with pdf.js.
Pick the model, set chunk size, and choose token limits to suit document length.
Start summarization. A progress bar shows chunk processing and final synthesis.
Read the final abstract (and optional partials), then download as .txt or copy.
Privacy & Security
Everything runs locally on your device. No files are uploaded or stored on a server.
Tip for Long PDFs
Increase chunk size gradually and keep partial token limits modest to improve coherence and speed. The first run downloads the model and caches it for future offline use.
Note: Results are best with clear, text-based PDFs. Password-protected or image-only PDFs may require OCR before summarizing.
Extract with pdf.js and compress with @xenova/transformers. No servers, no API keys—just results.
All processing runs in your browser. No uploads, no accounts, no tracking.
Great for confidential documents.
Transformers.js downloads a compact model once and caches it for offline use.
pdf.js parses your PDF pages into clean text for consistent downstream summarization.
Long PDFs are split into chunks → partial summaries → a concise final synthesis.
Tune chunk size and token limits to balance speed and detail for any file.
A lightweight HUD reports extraction and summarization progress as it happens.
Inspect each chunk’s gist to verify coverage or create sectioned notes.
One-click download to .txt for sharing or archiving, or copy directly from the UI.
Well-structured abstracts that are easy to scan and reference later.
