wtf is claw?

CLAW is a drum machine and groovebox that runs entirely in your web browser. There is nothing to install and no account to create. Every sound comes from live synthesis using the Web Audio API, so no audio samples are bundled with the project. Open the page, press play, and a loop is running within a few seconds. The instrument gives you eight synthesized tracks: kick, snare, clap, closed and open hi hats, sub bass, an acid style lead, and minor chord stabs. A 16 step sequencer controls the pattern, with swing, a master filter, and per track level and mute controls. One press generators can build techno, house, acid, or breaks style patterns automatically using rhythm and note pattern algorithms, and a MUTATE button nudges an existing pattern while it keeps playing. CLAW also supports AI assisted pattern creation. You describe a loop in plain language, such as a dark rolling techno beat with minimal hats, and connect your own API key from Anthropic or any OpenAI compatible service. The key stays in your browser and is sent directly to the provider you choose, since CLAW itself has no backend servers. Finished work can be arranged into a full song using loop and song modes, then exported as a WAV audio file, as separate WAV stems for each track, or as a Standard MIDI File that keeps your note velocities and swing. These exports can be dragged into music software like Ableton, FL Studio, or Logic. Patterns can also be saved as JSON project files, shared through URLs that track remix history, and the browser autosaves your work. The app installs as a Progressive Web App and works offline. The project is aimed at DJs, music producers, and hobbyists who want a fast way to sketch ideas without cost or setup. It has no build step or external dependencies beyond a browser, and it is released under the MIT license, so it can be reused, modified, and shared freely.
