Jam, sing, and write songs
together.
Refrain is a social platform for musicians at every level — real-time jam rooms, multiplayer karaoke with live pitch coaching, and weekly songwriting circles with an AI co-writer.
Jam Rooms
Hop into a synced room with a click track, chord changes, and visual scale helpers. Record any moment and share it instantly.
Karaoke Studio
Turn any song into a singable karaoke track — AI-aligned lyrics, vocal remover, and real-time pitch feedback when you take the mic. Sing solo or in synced parties.
Songwriting Circles
Weekly themed prompts, demo swaps, timestamped feedback, and an AI co-writer to break through writer's block.
One platform. Three musical lives.
Your karaoke streak earns you XP. Your jam-room buddies become co-writers. Your songwriting demos become karaoke songs. It all flows together.
One profile, three skills
Track instruments played, vocal range, songs co-written, and pitch accuracy on a single profile that grows with you.
AI that respects your voice
Suggest rhymes, chord progressions, and melody continuations only when you ask — never auto-finishing your song.
Built for messy real life
Loose-jam mode for the latency reality of the public internet, loop mode for tight rhythm sections, async circles when life gets busy.
Your music, your library
Every jam clip, karaoke take, and demo lands in your Audio Library — taggable, shareable, exportable.
Stuck on a line?
Try the co-writer.
Refrain's AI co-writer suggests rhymes, next lines, chord ideas, and titles — only when you ask. It never auto-finishes your song. Try one of the prompts on the right.
Suggestions only — never auto-completes your song.
Built for musicians at every stage
Whether you've never held an instrument or you tour for a living, there's a room, a song, or a circle for you.
