From a vibe to a finished track
Describe it, get two takes, play the karaoke, and refine on the same thread. Step through each beat.
Start with a style. Give Theo a genre and a topic — or open the Advanced studio. Write your own lyrics, let Theo write them, or go instrumental.
A full music studio in a chat
From ad jingles to album-ready tracks — composed, covered, and organized.
Two versions per song
Every request composes two takes in parallel so you can pick the one that hits — no re-rolling from scratch.
Lyrics your way
Write your own lyrics, let Theo write them from a topic, or go instrumental. A songwriting pass keeps hooks tight.
Karaoke player
Each song ships with a 9:16 player that streams time-synced lyrics over the artwork — plus full-screen immersive mode.
AI cover art
Every version gets its own generated cover art matched to the song's mood, ready for sharing.
Start from your own audio
Record or upload a clip and Theo can cover it (keep the melody, restyle everything) or borrow its style for a new track.
Revise on the same thread
“Make the chorus more upbeat” or “switch to acoustic” re-renders new takes while keeping the song's identity.
Your song library
Every generation lands in your library with playlist-style workspaces to organize tracks by project or mood.
Quality tiers
Pick fast drafts for exploration or premium renders when it matters — Theo routes each request to the best engine mix.
Every genre
Pop, hip-hop, EDM, lo-fi, cinematic scores, country, jingles for ads — describe the style and Theo composes to it.
How it works
Describe the song
Give Theo a style and a topic — “dreamy synthwave about late-night coding” — or open the Advanced studio for full control.
Choose your lyrics
Paste your own lyrics, have Theo write them, or keep it instrumental. Add your own audio if you want a cover or remix.
Get two takes
Theo composes two versions with cover art and synced lyrics. Play them side by side and keep your favorite.
Refine and share
Ask for revisions on the same thread, then download the track or share it straight from your library.
Frequently asked questions
How long does it take to generate a song?
Songs render in the background — typically a few minutes for both versions, including cover art and synced lyrics. You can keep working anywhere in OpenCharts and get notified when they're ready.
Can I use my own lyrics?
Yes. Paste complete lyrics and Theo composes around them, give it a topic and it writes lyrics with a professional songwriting pass, or skip lyrics entirely for an instrumental.
Can I remix my own recordings?
Yes. Record from the mic or upload a clip, then choose cover mode (keeps your melody and words while restyling the production) or style mode (borrows the vibe for a brand-new track).
Can I edit a song after it's generated?
Ask for a revision in the same thread — “more upbeat chorus,” “swap to acoustic,” “slower tempo” — and Theo renders fresh takes that keep the song's style and lyrics intact except for your change.
Where do my songs live?
Every song lands in your Symphony library with its versions, artwork, and lyrics. Organize tracks into playlist-style workspaces and play them anytime with the karaoke player.
