I was tired of instrument tuners buried in ads, nag screens, and subscriptions just to tune a guitar. So I built one that asks for nothing in return. Behind a deliberately plain full-screen needle sits a hybrid pitch-detection pipeline, and it all runs on-device, no app and no network.
Transfer files directly between any two devices with a browser and a camera, regardless of the operating system. All data is sent peer-to-peer via WebRTC, encrypted end-to-end, and never touches a server. Even the connection handshake avoids one: the devices pair by showing each other QR codes, so the keys are exchanged by camera rather than by a middleman.
A theremin is that rare instrument you play without ever touching it. This one needs no instrument at all: lay your phone flat, hover a hand over the camera, and hand-tracking turns the space above it into pitch and tone, synthesized right in the browser and never leaving your device.
My kids and I play a lot of dice, and we kept arguing over whether a risky roll was really the smart move. So I fell down a rabbit hole of academic papers on optimal play and ported a strategy engine to TypeScript. It now lives behind 3D physics dice with synthesized roll sounds, telling you the best move whenever you’re stuck.
I kept needing quick GIFs from short clips, but every converter felt like a detour through uploads, accounts, and watermarks. gifsky keeps that workflow local: drop in a video, trim the moment on a scrubber, and let a WebAssembly build of gifski encode the selected frames in your browser.
Every time I needed a photo without its background, the tools wanted my picture on their servers, an account, or money for the full resolution. Begone runs a segmentation model right in the browser, on the GPU where it can, then cleans up soft edges and keeps the real shadow if you want it. It works offline, and your images never leave your device.
A friend told me the only thing that reliably puts them to sleep is a ten-hour YouTube recording of an arctic blizzard. I ran the recording through an analysis script to measured its spectrum and the rhythm of its gusts. I then rebuilt the storm as a synthesizer that stays close to the original: layered noise shaped into rumble, wind, howl and snow, with a sleep timer and a mixer. It plays offline, with no stream and no ads. Maybe it helps others drift off too.
