ProtoNote turns Claude-built prototypes and artifacts into shareable review links. Say 'make this a ProtoNote' and Claude publishes your HTML to a hosted, sandboxed page with a share link. Teammates open it with no account, type a name, and pin threaded feedback notes to the exact spot on the rendered page — on the exact version. Push revisions to the same link, get email digests as notes arrive, then pull open notes back into Claude with their positions to apply the changes. Reviewing is always free for everyone you share with.
