The page lasts, not the file
Every page keeps its own history, with a before and after.

Upload a PDF and send your client one link. Each new round lands at the same address, and comments stay in place.

Multi-page PDF, straight out of InDesign, Figma, Illustrator or Keynote.
Your client clicks the page and writes a few words. You get an instruction pinned to the spot, not a paragraph to decode.

On a text selection your client can write the wording that should replace it. You get copy you can paste, not a description of the change.

Every comment carries a status, a decision and the name of whoever took it. Your client can see whether their note was taken and which round it landed in.
You can also decline a comment, but only with a reason.

Every page keeps its own history, with a before and after.

They open the link and type a name. No account, nothing to install.

Links for commenting or view only. Revoke any of them when the project ends.
On every plan, your clients comment with no account, no limit and no charge.

On paid plans a document is deleted 180 days after the last activity on it, on the free plan after 30 — the PDFs, the page previews and the comments go with it. As long as anyone is still working on it, the clock starts over. We warn by email fourteen days before deletion.
Only people you send the link to. The link carries a secret token, so nobody guesses their way in, and you can switch commenting off for the whole document at any time.
The files stay yours. We claim no rights to them and use them for nothing beyond showing them to people with the link. Whoever uploads a file answers for its content and for holding the rights to it.
The PDF is split into single pages, each page gets a preview, and each preview is compared with the same page from the previous round. It runs automatically — that's how the changed pages are found.
No. A protected file has to be unlocked first — otherwise it can't be split into pages or rendered.
