Summarise any document — keep the receipts.

The best summariser is one you can trust — which means one that shows its work. Sidenote summarises any PDF, document or page open in your browser and attaches a citation to every point, so you can click and see the exact passage it came from. Generic summarisers give you a fluent paragraph with no way to check it; Sidenote gives you a summary you can verify in a click.

Open the PDF in your browser, open the Sidenote side panel, and pick a length — TL;DR bullets, a tight paragraph, or a structured deep read. Sidenote reads the document in place (no upload, no copy-paste) and returns a summary where every claim cites the passage it came from. Click any citation and the PDF scrolls to that line and highlights it.

Yes. Long PDFs, arXiv papers, contracts and reports are where a cited summary matters most. Sidenote handles the whole document, pulls out the key points, and links each one back to its source passage so you can jump straight to the part that matters instead of re-reading 40 pages.

Yes — scanned or image-only PDFs are OCR'd first, so even a document with no text layer becomes summarisable and citable.

Any model can drift from the source. Sidenote is built against that: every summary is checked server-side against the passages actually retrieved from your document, and anything it can't ground is dropped before you see it. If the document doesn't support a point, it won't appear with a citation. See how citations work for the full detail.

Word documents, PowerPoint files, web articles, and pages in Confluence, Notion, SharePoint and Google Docs — anything you can open in your browser or connect read-only. One summariser across every source you read.
