Made for worship teams
One recording, charts for everyone.
Chart the song once, transpose it for whoever's leading.
Record the arrangement your team plays, and Matra writes the lead sheet — melody, chords, key. Transpose to your vocalist’s range in a tap. Print PDFs for the band. Your originals and custom arrangements stay private.
Free during early access · no card · private by default

Questions, answered
Can we chart worship songs we didn't write?
You can chart your team's own recordings and arrangements, privately, for your team's use. Matra doesn't publish or distribute transcriptions of copyrighted songs.
How accurate is it?
Chords and key are our strongest outputs and carry per-chord confidence so you always know what to trust. Staff notation is early access — honest but imperfect today, and improving as the engine trains on more recordings.
What does it cost?
Right now — nothing. Matra is free during early access (fair use: about 20 recordings a day), and every file still shows its real Token price so there are no surprises later. The meter: about 1 Token per 15 seconds, a typical 3½-minute recording ≈ ◇14. When billing starts, early-access musicians keep ◇600 — plus half price for 3 months and 25% off the rest of their first year. Sargam and notation views cost nothing, ever.
Is my audio private?
Yes. Uploads are private by default, nothing you make is published anywhere, and we never train on your audio.
Built with the musicians who use it.
Matra is in early access. Fix a chord or a note the engine got wrong, and we gift you Tokens as thanks — your ear makes the engine better for everyone.
