What it does
Seven million camera glasses sold last year. You can't see them — but your phone can hear their Bluetooth. Counterlens maps camera glasses, GoPros and AI recorders around you, grades every detection, shows the evidence, and admits what it can't hear. Free, no data collected.
Counterlens is a smart glasses detector for iPhone: an honest radar that finds Ray-Ban Meta and other camera glasses, GoPro-class hidden cameras, and AI recorder pendants nearby via Bluetooth. Evidence behind every alert, zero data collected.
Smart glasses look like glasses. Pocket cams clip to shirts. AI pendants record all day. Counterlens listens to the radio signals capture hardware can't help leaking — and maps it around you, with the evidence to back every alert. Smart glasses stopped being a novelty somewhere between 2024 and now. Meta and EssilorLuxottica sold 7 million pairs in 2025 alone — more than triple the year before — and are scaling production toward 20 million a year . Meta holds over two-thirds of the market. This isn't a gadget story anymore. It's the ordinary eyewear on the face across from you. That was the whole social contract. Someone raised a phone, and you knew — you could step out of frame, object, or…from counterlens.app

Glasses to detect smart-glasses that have camerasNov 2025 · github.com · ▲509Hi! Recently smart-glasses with cameras like the Meta Ray-bans seem to be getting more popular. As does some people's desire to remove/cover up the recording indicator LED. I wanted to see if there's a way to detect when people are recording with these types of glasses, so a little bit ago I started working this project. I've hit a little bit of a wall though so I'm very much open to ideas! I've written a bunch more on the link (+photos are there), but essentially this uses 2 fingerprinting approaches: - retro-reflectivity of the camera sensor by looking at IR reflections. mixed results…

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…
