BotSong

Turn a musical idea into a complete song with BotSong, a MIDI composition and karaoke studio designed for Android.

DESCRIBE YOUR SONG
Simply specify the mood, style, or instruments you want. BotSong will build an original composition from your idea.

COMPOSE AND ARRANGE
Choose the genre, tempo, scale, time signature, and duration. Work on each instrumental track, adjust the volume, cut or isolate instruments, and arrange verses, choruses, bridges, and other sections.

CREATE LYRICS AND KARAOKE
Add your lyrics, sync them, and produce karaoke-ready KAR files.

EXPORT YOUR PROJECT
Export your creations as MIDI, KAR, WAV, and JSON to save, share, or continue editing in your music software. You can also import existing BotSong projects.

TWO THEMES, ONE COMPLETE INTERFACE
Use BotSong in light or dark mode, on your phone and tablet, with a local library to easily find your projects. Your compositions stay on your device.

TWO OPTIONS FOR FULL EXPORTS
All creation and editing features are available for free. Without an active paid subscription, only MIDI and KAR exports are limited to 15 seconds. A monthly auto-renewing subscription for €4.99 or a one-time lifetime in-app purchase for €29.99 unlocks full access. You can cancel your subscription at any time through Google Play.
