Pricing
One plan, founder-priced
While Euterpe is invite-only there is exactly one subscription: Founder Pro, $9 a month, everything included. It exists to thank the people who show up early — founder pricing is limited to the first 100 founders, and the price stays locked for as long as you stay subscribed.
Founder Pro — $9 a month
The whole catalog
All 73 kits and their 499 presets — and every kit we publish later, granted to you automatically. That's the founder promise, and it's wired into the software, not a slide.
500 credits, monthly
Enough for hundreds of generations a month. A Lite generation costs 1 credit, a preset 4, a kit variation 5, and a brand-new AI-authored kit 15–18.
MelodySketch included
The melody add-on ships inside Founder Pro: AI toplines you can play in the browser, refine in plain words, and export as WAV or MIDI for Suno's Cover.
14 days free, no card
Invites land in a full Pro trial with 100 credits and no payment details. If you let it lapse, your library stays readable and your own presets stay copyable.
The price lock
$9 is the founder rate, and it follows your subscription, not the calendar. Public-launch pricing will be higher; yours won't move while you stay subscribed.
The founder line
Invite-phase support is the founder's own inbox, not a ticket queue. Kit requests welcome — the catalog grows where its musicians point it.
Top-ups, for the hot streaks
Monthly credits refill with your subscription. When a session runs hot, top-up packs stack on top — a click through Stripe checkout, applied instantly.
The money questions
What does a generation actually cost?
In credits: a Lite single-prompt generation is 1, a full preset is 4, a kit variation — the core loop — is 5, a premium storytelling variation is 12, and AI-authoring a whole new kit runs 15–18 depending on the mode. MelodySketch takes are 4 and revisions 3. Cached Lite repeats are free.
What happens if I cancel?
You keep access through the period you've paid for. After that your library goes read-only: everything you made stays visible and your own presets stay copyable — you just can't generate until you come back. Cancelling also ends the founder price lock.
Is the trial really no-card?
Yes. An invite code starts 14 days of full Founder Pro with 100 credits, and we ask for a card only when you choose to subscribe. Checkout and billing run entirely on Stripe — we never see your card.
Will the price change?
For you, no — $9 a month for as long as your subscription stays active. For the public, yes: launch pricing will be higher, which is rather the point of showing up early.
