Frequently asked questions about ProtoNote
Do reviewers need an account?
No. Reviewers can type their name and start reviewing immediately without signing up.
How do I integrate ProtoNote with Claude?
ProtoNote works as a Claude connector/MCP tool. You can ask Claude to 'make this a ProtoNote' and the share link is returned in chat. You can also pull open notes back into Claude to apply feedback.
What happens to feedback when I upload a new version?
Notes pin to the exact spot on the exact version they were made on. When you ship v2, old notes stay with the old version.
Is my work private?
Yes, ProtoNote is private by default. Work is only visible to people you send the link to.
