Practice AI

Local music practice tools: synced speed, pitch, loops, EQ, and on-device AI vocal removal. No uploads.

Practice AI adds local music practice tools to supported music sites, including tempo control, pitch shift, loop points, EQ, effects, and on-device AI vocal removal. Use the extension on YouTube or SoundCloud. Open a supported music tab, open the Practice AI popup, and choose practice controls or local AI processing modes. Audio processing runs in the browser extension using bundled assets and local Web APIs. The extension does not upload audio. Optional account features use Firebase email/password authentication when configured. Optional paid upgrades open Freemius hosted checkout in a separate tab. Optional, off-by-default product analytics send anonymous usage events to PostHog only when you enable analytics in settings; no audio or content of what you play is included.
