ProtoNote

What it does

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.

Share AI-built prototypes and Claude artifacts with your team and collect pinned notes directly on the page. Upload HTML, Markdown, images, or PDFs — free.

Share AI-built prototypes and artifacts with your team and collect pinned notes directly on the page. Free, and private by default. Only visible to people you send the link to. 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. 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…from protonote.io

  Clipto MCP▲655

  Hey HN, We recently built Clipto. It’s a tool that lets you search over terabytes of video, audio, and images on your computer, without relying on the cloud. Motivation: we probably all had this similar experience, we know a moment exists in a video or audio, but finding it takes hours scrubbing the timeline. You can send all the media to process in the cloud, but it’s slow, expensive and raises privacy concerns. So we decided to build our own on-device media search engine. How it works (high level): 1. We ingest video, audio, image; normalize formats via ffmpeg; run content analysis to…

  Simple algorithm and color space to generate diverse skin tones▲627

  Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…
