ProtoNote - Share AI-built prototypes, get feedback pinned to the page

Drop in an HTML prototype, image, or PDF and get a shareable link. Reviewers leave notes pinned to the exact spot on the page. No account required, just a name. Use the Claude connector to turn anything you build into a ProtoNote right inside the chat. When notes come in, tell Claude to pull them in and apply the changes. The new version publishes itself. Free tier includes 3 active prototypes with unlimited reviewers and notes. Reviewing is always free.
