Upload
Download and drop what you just built. An HTML file, a screenshot, a PDF. Or don’t even download it: tell Claude “make this a ProtoNote” and the share link comes back in chat.
Upload several files together. They become pages of one project, each with its own notes.
All of your prototypes get a permanent home. Folders keep them organized instead of lost in ten thousand chats.
Share
Send one link. Your work is hosted for you and presented like a product, not an attachment. It opens on any device, with a real preview in Slack, your name, and a note on what to look at.
No account needed to review. Your manager types their name and starts. No signup wall has ever improved feedback.
You’ll know it landed: “Viewed by Maya · 2h ago,” right on your dashboard.
Get notes
Notes pin to the exact spot, on the exact version. They appear live as your team reviews. Ship v2 and the old notes stay where they belong.
No refreshing the dashboard. You’re notified as notes and replies come in.
The loop
Then the feedback goes back to work. Pull your ProtoNotes into Claude and apply the changes. Reviewers stay in their browser, you stay in your chat.
