Hey Product Hunt 👋
I build prototypes in Claude constantly. Sharing them is still miserable. My actual workflow was: download the HTML, drop it in Slack, hope someone opens it. They'd open it in a browser tab with no way to comment, so I'd get "looks good!" back, or a screenshot with a red circle drawn on it, or nothing.
So I built ProtoNote. You drop in what you made and get a share link. Whoever you send it to types their name and starts leaving notes pinned to the exact spot on the page. No account, no signup wall, nothing for them to install. The part I'm most excited about: it's a remote MCP server, so it runs as a Claude connector. Say "make this a ProtoNote" and the share link comes back in chat, no download step at all. When notes come in, say "pull my open notes and apply them." The new version publishes itself.
Built solo. Free for 3 prototypes, $10/mo for unlimited, and reviewing is always free so nobody you share with ever hits a paywall. Curious how people here handle this today. When you build something with AI and need eyes on it, what do you do?
The scattered screenshots and vague "fine by me" replies have quietly worn me down for years, so feedback that lands right on the spot it's about feels so much saner. Nice work, @zach_friesen.
The feedback loop between building and improving prototypes is usually the painful part. Making comments more contextual and connecting them directly with AI workflows feels like a smart way to speed things up.
As a Product Owners moving from Figma to Claude Code and constantly looking for feedbacks from stakeholders and testing users, this is life saver for me!

Who hunted ProtoNote?
ProtoNote was hunted by Zach Friesen. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
