Terms & refunds
Effective 2 September 2026Plain language, because that's the whole brand. Using Timbrel means you agree to what's below.
What Timbrel is
Timbrel is a guided builder that turns your answers into a “voice file” — a portable document of style instructions you can give to an AI model. The Starter file is free. Full ($59) and Studio ($199) are one-time purchases. No subscriptions.
Your file is yours
You own the voice files Timbrel generates for you — use them personally or commercially, edit them, keep them forever. We claim no rights over anything you or your AI write with them. The one thing you can't do is resell the files themselves (or a thin wrapper around them) as a competing product.
Studio, and writing in someone else's voice
Commercial use is included. A Studio licence covers using the voice files, and the writing produced with them, in paid client work. You may bill for that work. Nothing here is a per-seat or per-project fee.
A Studio locker holds ten voices. The intake link you send collects answers from the person whose voice it is; if the locker is full their build still completes and they still receive their own file, it simply isn't filed into your locker.
Two things worth saying plainly, because they protect the person on the other end of an intake link. The voice belongs to whoever answered the questions: they get their own record, their own access key and their own emailed copy, and holding their voice in your locker is a reference rather than ownership. And a locker token is a credential — whoever holds the link holds the locker, so treat it the way you would a password.
Payments
Checkout is handled by Lemon Squeezy, our merchant of record — they process the payment, handle applicable VAT/sales tax, and issue the receipt. We never see your card details.
Refunds — 14 days, no questions
If the file isn't what you hoped, email hello@timbrelai.com with your Voiceprint ID or receipt within 14 days of purchase and we'll refund it in full. You don't have to explain. (You can even keep the file — deleting text from your computer is not a business model.)
Free updates
Paid files are regenerated from your stored answers each time you fetch them, so engine improvements reach you at no extra cost via your Voiceprint ID link. If we ever retire that endpoint, your downloaded files keep working — they're plain text.
What we can't promise
A voice file steers an AI model; it doesn't control one. Results vary by model, by prompt, and by how models change over time. Timbrel is provided “as is” — we promise honest effort and a working product, not specific outcomes from a third-party AI. Our total liability for anything is capped at what you paid us.
Fair use of the service
Don't abuse the free tier with automation, probe the paid endpoints, or use the builder to violate the law. We may block traffic that does.
Changes
If these terms change materially, we'll update this page and the date above. Continued use after that means you accept the new version.
