FAQ

Free AI summarizer - common questions.

Yes: free, no sign-up, no card. Paste a link or upload a document and you'll get a concise summary in seconds.
A web article or any public page by URL, or an uploaded PDF, Word (DOCX), PowerPoint (PPTX), plain text (TXT), Markdown (MD / MDX) or RTF file - up to 4 MB.
No. The free tool extracts the text, summarizes it, and keeps nothing - there's no account and the file isn't saved.
This tool gives you a plain summary. Sidenote (the extension and web app) cites every point to the exact passage and scrolls you straight to it, and lets you chat with the document, build a glossary, and save it to your library.
Free summaries cap how much text they read, so very long documents are summarized from their first portion. Sign up to Sidenote to summarize whole long documents end to end.
Not on the free tool - a scanned PDF has no text layer and needs OCR first. Sign up to Sidenote to OCR and summarize scanned documents.
