What it does
Paste any company's pricing page. PromiseProof pulls out every consequential promise — guarantees, performance figures, superlatives, breadth claims — quoted word for word, and flags which ones a careful buyer would want evidence for. It never calls a company dishonest. It says what was promised, in their words, before you're six months into a contract arguing about it. Free, no account, no email. Deterministic, not an LLM — if the wording isn't on the page, it isn't in your result.

Paste any company’s pricing or product page. We pull out every consequential promise — guarantees, performance figures, superlatives, breadth claims — word for word, and tell you which ones a careful buyer would want to see evidence for before paying. Free. No account, no email address. We read only the page you name, and only what its robots.txt allows. The promises on a sales page are the ones you will want to hold a vendor to later, and they are also the ones nobody writes down before signing. Six months on, the argument is about what was said, and the page has quietly changed.

Clipto MCP▲655Hey 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…

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…
