Comment Summary

Extract and summarize all PDF annotations. Right in your browser. 100% free, privacy protected.

Comment Summary collects every annotation in a PDF — sticky notes, highlights, underlines, strikethroughs, drawing markup and replies — and lays them out as a readable list with page numbers, authors and dates. Chasing review feedback by scrolling through a marked-up document is slow and easy to get wrong; a single ordered list of what everyone said is far easier to work through and to hand back to a team. The summary can be exported so it can be circulated separately from the document, and extraction happens in your browser.

Frequently Asked Questions

Which annotation types are included?

Sticky notes, highlights, underlines, strikethroughs, free text, shapes and ink markup, together with their replies.

Does it show who wrote each comment?

Yes, where the annotation records an author, along with its page number and timestamp, so review feedback can be attributed and sorted.

Can I export the summary?

Yes. The collected comments can be exported as a separate document to circulate to reviewers.

Does it change the original PDF?

No. This tool only reads the annotations. The source document is untouched.
