## What is CoComposer.ai?

CoComposer.ai is a creative piano companion for musicians, songwriters, and anyone exploring musical ideas.

Instead of asking AI to write a song from a text prompt, you begin with music. Record a phrase on an acoustic piano with your device microphone, play the on-screen piano, or connect a MIDI keyboard, then ask CoComposer.ai to generate a continuation that responds to your take.

Keep the versions that inspire you, reject the ones that do not, and try again with different creativity settings. The goal is not to replace your creativity, but to give you a responsive musical partner when you are looking for the next idea.

Features:
- Record piano ideas with an acoustic piano using your device microphone, a MIDI keyboard, or the on-screen keyboard
- Generate AI continuations from your own musical take
- Create multiple human and AI takes without losing earlier ideas
- Save and revisit ideas in your song library
- Adjust creativity settings when you want more control
- View and edit music in the MIDI Timeline or Score view
- Edit notes, copy/paste sections, and remove silence
- Import and export MIDI
- Export WAV audio

For the best experience, use an acoustic piano or a MIDI keyboard. The on-screen piano is useful for quick sketches and playful exploration, but a real keyboard gives CoComposer.ai a more expressive musical take to continue.

CoComposer.ai is currently focused on piano. Imported MIDI files with multiple instruments can be flattened to piano, or you can import piano tracks only.

AI generation runs on your device, so no server is required for composing. Generation speed depends on your device, and older iPhones or iPads may take longer to produce a new idea.

If you choose to rate an AI take, anonymous MIDI feedback and model settings may be sent to help improve the model. No name, email, or audio is sent.
