What it does
Scan any LLM for OWASP Top 10 vulnerabilities — jailbreaks, prompt injection, PII leakage. Works with OpenAI, Anthropic, Gemini, Azure, Ollama and custom LLMs.
FilterPrompt is a drop-in AI firewall proxy for LLM apps. It inspects every prompt and response across OpenAI, Anthropic, Google Gemini, Azure OpenAI, and any OpenAI-compatible endpoint to block prompt injection, redact PII, stop jailbreaks, and enforce per-tenant policy in real time. FilterPrompt sits between your application and any LLM provider. Every request is scored by layered detectors — pattern rules, semantic models, structural validators, PII regex, and ML toxicity classifiers — before it reaches the model. Responses are filtered the same way on the return path. Most LLM products ship without input/output controls. The first prompt injection or PII leak becomes an incident.…from filterprompt.io

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…
