Common questions

Will the free tier stay free?

Yes. The core chord-finder — our AI chord engine, enhanced 7th & suspended chords, the chord chart on the timeline, transpose and export — stays free for everyone. Paid plans add quota, longer files, stem separation and history on top.

How are quotas counted?

One analysis per uploaded file. Failed analyses don't count against your daily limit — you only spend a slot when the chart completes. Quotas reset at UTC midnight.

Do I need an account?

No. Guest uploads work end-to-end. A free account gets you a persistent history, public share toggles per analysis and a higher daily quota.

Can I cancel anytime?

Yes. Cancel a Supporter or Pro subscription in one click from the billing portal — no email, no hoops. Your paid features stay active until the end of the period you've already paid for, then the account drops back to Free.

Is the Lifetime plan really a one-time payment?

Yes — Lifetime is a single payment, not a subscription. There is no monthly bill and nothing auto-renews. You unlock the bigger caps, longer tracks, extended history and 6-stem separation, and they stay with your account.
