A client brief that keeps the same link after edits

We build NOS Workspace. Here is one use case: you have a client brief as an HTML file, but the delivery date changes after you send it. Paste or upload the file, edit the date on the page, and keep the existing share link. The brief can live beside your other documents.

You can paste, edit and preview without signing up. Creating a share link needs an account; the client does not need one to read it. The free plan includes 3 active share links.

If you send HTML briefs or reports to clients, what is the awkward part of handing them over?
