What gets shared?
Notes stay in this browser until you choose Share with agents. Sharing uploads the selected page’s notes, DOM evidence and optional screenshots to your MarkupRelay account. Review them for private information first.
Shared edits sync while connected. Click Retry after an offline error. Stop sharing removes the cloud copy; content already retrieved by an agent cannot be recalled. Cloud shares expire after 30 days without an update.
Connect Codex or Claude using the setup guide, then ask it to work on your shared page. Revoke agent access from your account.
