Terms & Conditions

1. Who can use the Service

You must be at least 18 years old, or the age of majority where you live, and able to enter into a binding contract. If you use the Service for an organisation, you confirm that you have authority to accept these Terms for it.

2. The Service

KUKU Labs is a web studio. Today it offers Text to Speech (turning text you write into spoken audio), Voice Cloning (creating a reusable digital voice from a sample you provide) the Voice Enhancer (cleaning up a recording: removing noise and echo, evening out the volume and setting its loudness) and the Voice Editor (a multitrack editor for arranging, trimming, enhancing and exporting audio; free to open; enhancing inside it is free and unlimited, while generating uses the allowances below). Other tools shown on the site (Thumbnail Generator and Script Writer) are marked “Coming soon”, are not yet available, and may change or may never launch.

The voice engine and the Voice Enhancer run in your browser. The first time you use them, your browser downloads the model and keeps it for later visits. Generating speech or enhancing audio uses your device’s processor, memory, storage and internet data. You are responsible for any data charges, and speed and quality depend on your device.

For your convenience your browser keeps your last five generations in its own storage, so a reload does not lose them. We never receive them and cannot recover them: if you sign out, clear your browser’s data, or make a sixth generation, the oldest is gone, so download anything you want to keep.

3. Your account

  • You sign in with a link we email you, with Google, or with a password you set. Keep access to your email and your Google account secure, and keep your password to yourself.
  • You can try Text to Speech without an account, within a small daily allowance that we may change or end.
  • You are responsible for everything done through your account.
  • Accounts and plans are personal. Do not share, sell or transfer them.
  • Tell us promptly if you think someone else has used your account.
  • We may refuse, suspend or close accounts that break these Terms.

4. Plans, payment and access

You can use the Studio with a free account, within the free allowance described below; a plan is not required. The Basic plan is a subscription costing US$10 a month, or US$100 a year (shown on the checkout page as “Basic plan” and “Basic plan (yearly)”), and includes text to speech and voice cloning with no limit on the number of generations, subject to the fair-use rule and the per-generation limit below. The Voice Enhancer is free for everyone, with or without a plan. The price shown when you subscribe applies to the period you choose. A Pro plan (US$20 a month or US$200 a year) is coming soon: it cannot be bought yet, and its price and contents may change before it launches.

  • How you pay. You pay for a plan by card, or another method Stripe offers where you live, on Stripe’s secure checkout page. Stripe processes the payment; this website never sees or stores your payment details. The price is shown before you pay, and is charged in US dollars.
  • Free allowance. Without a plan, every account can generate Text to Speech as often as it likes, up to 5,000 characters a week in all. The week runs from Monday 00:00 UTC; unused characters do not carry over. A generation that fails or that you cancel is not counted. It includes voice cloning: speaking with a cloned voice uses the same characters. It is offered at our discretion and we may change or end it.
  • Activation. Your plan switches on automatically as soon as Stripe confirms your first payment, which is usually within seconds. If it does not, contact us with the email you paid with and we will activate it by hand. Your plan period starts when it is activated and ends on the same date the next month (or the next year, if you chose yearly): for example, a plan bought on 4 December runs until 4 January. Where the next month has no such date, it ends on that month’s last day.
  • Automatic renewal and cancellation. The Basic plan renews automatically at the end of each month (or year) and we charge your payment method the price shown at checkout, until you cancel. You can cancel at any time from the Account page. Cancelling stops future renewals, and you keep your plan until the end of the period you have already paid for. We do not refund a period that has already started, unless the law says otherwise. If a renewal payment fails, Stripe will try again for a while and may email you; if it cannot be collected, the subscription ends. If we change the price, we will tell you before it applies to you, and you can cancel before then.
  • When a plan ends. If you have cancelled (or a renewal cannot be collected), unlimited generation stops at the end of the period you have paid for and your account goes back to the free allowance of 5,000 characters a week. Voices saved in your browser stay there and can still be used within that allowance. Unlimited generation returns when you subscribe again (or we continue your plan).
  • Voice Enhancer. The Voice Enhancer is free and unlimited for every signed-in account, with or without a plan: enhance as many recordings as you like, each up to 30 minutes long, in the Voice Enhancer or the Voice Editor. Enhancing happens on your device and the result is not stored by us, so download it when it is ready.
  • Limits. A single generation can contain up to 10,000 characters with a plan (on the free account, up to 5,000 characters a week in all). We may adjust limits to keep the Service reliable.
  • Coupon codes and referral links. A coupon code or a referral link can reduce the price of your first payment: US$2.00 off the monthly plan or US$10.00 off the yearly plan. It is for new subscribers only, one per customer, cannot be combined with another offer, has no cash value, and does not change the price of renewals. You cannot use your own affiliate code. We may refuse or withdraw a code that is misused.
  • Sales. From time to time we may offer the Basic plan at a sale price. The site and the checkout show the sale price, how long it lasts (your first payment, a number of months, or every payment while you stay subscribed) and, where there is one, the date the sale ends. The sale price is what you are charged; when it stops applying, you pay the regular price shown when you subscribed. A sale does not combine with a coupon code; with a referral link or code you get whichever discount is bigger. Ending a sale does not change the price of anyone who already bought at it.
  • Fair use. “No limit” means no cap on the number of generations for ordinary personal and business use. We may limit or end use that is automated, abusive, or places an unreasonable load on the Service.
  • Taxes. Prices may not include taxes or payment-provider fees where these apply. You are responsible for them.

Refunds. Access is activated promptly and the voice model is delivered to your device straight away, so payments are generally non-refundable. If we cannot provide access, or a problem is our fault, contact us within 7 days and we will make it right, which may include a refund. A refund is returned to the payment method you used. When a payment is fully refunded, the month it bought is taken off your plan. Nothing in these Terms limits any right to a refund that you have under the law.

Price changes. We may change prices for future periods. A change never affects a period you have already paid for.

5. Acceptable use

You agree not to use the Service to:

  • break the law or help anyone else to do so;
  • create content that is defamatory, harassing, hateful or threatening, or sexual content involving minors or content that exploits or endangers children;
  • deceive, defraud or scam anyone, or spread false statements attributed to real people;
  • impersonate a person or organisation in a way that misleads others;
  • infringe anyone’s intellectual-property, privacy, publicity or other rights;
  • create more than one account to get more free characters or more Voice Enhancer runs.

You also agree not to:

  • share, resell or rent access to the Service, or share the voice engine files obtained through it;
  • bypass, tamper with or probe the plan checks or other security of the Service, or reverse engineer it except where the law allows;
  • use bots or scripts to run the Service in bulk, or place unreasonable load on it.

If you find a security problem, please tell us at kukulabsonline@gmail.com rather than exploiting it.

6. Voice cloning and consent

  • Only clone a voice that is your own, or when the speaker has given you clear, informed permission for the cloning and for the way you will use the result. You confirm this each time you tick the consent box.
  • The voice model we use (Kyutai Pocket TTS) is licensed on the condition that it is not used to clone or impersonate anyone without explicit and lawful consent, to deceive people (for example fake news, fraudulent calls, or presenting generated audio as a genuine recording of a real person or event), or to create unlawful, harmful, abusive, hateful or privacy-invasive content. You must follow these conditions too.
  • Never use a cloned voice to mislead people into believing a real person said something they did not, to commit fraud or harassment, or to get past voice-based security.
  • Where the law or a platform’s rules require it, tell your audience that audio is AI-generated.
  • You are responsible for complying with laws on privacy, personality and publicity rights, consent and AI-generated media.
  • We do not listen to your samples and cannot verify consent, so responsibility for it is yours. We may suspend accounts that misuse voice cloning.

7. Your content and generated audio

Your text, recordings and generated audio are processed in your browser and are not sent to us. We claim no rights in them. As between you and us, you own what you create, to the extent the law allows, and you are responsible for it and for how you use it.

The voice model and speech engine are made by third parties and are provided under their own licences. Who made them, and under which licences, is on our Credits page. You must use the Service and its output consistently with those licences, which may place limits on how generated audio can be used.

8. Our intellectual property

The KUKU Labs name, logo, website design and our own code belong to us or our licensors. The Service also includes open-source and third-party components that remain under their own licences (see Credits). We give you a personal, non-exclusive, non-transferable, revocable licence to use the Service while your plan is active and in line with these Terms. All other rights are reserved.

9. Availability and changes

We work to keep the Service running but do not promise that it will always be available, error-free or fast. Maintenance, problems with our providers, or third-party services we depend on (such as the sites that host the voice model) may interrupt it. We may change, suspend or withdraw features at any time. If we withdraw something you have paid for and cannot provide it, we will give a fair refund for the unused part of your period.

10. Suspension and ending

  • You may stop using the Service at any time and delete your account on the Account page.
  • We may suspend or end your access immediately if you break these Terms, create risk or legal exposure for us or others, or where the law requires.
  • When access ends, your right to use the Service ends. Deleting an account ends any remaining plan time. There is no refund for this except as described under “Plans, payment and access” or as the law requires.
  • Sections that by their nature should continue (ownership, disclaimers, liability, indemnity and governing law) continue after access ends.

11. Disclaimers

To the fullest extent the law allows, the Service is provided “as is” and “as available”, without warranties of any kind, express or implied, including fitness for a particular purpose, accuracy, non-infringement and uninterrupted operation. Synthetic speech can contain mistakes, mispronunciations or unexpected sounds, so check it before you rely on it or publish it. We are not responsible for how you or anyone else uses generated audio.

12. Limitation of liability

To the fullest extent the law allows, KUKU Labs and its owners, staff and suppliers are not liable for indirect, incidental, special, consequential or punitive damages, or for lost profits, revenue, data or goodwill, arising from your use of the Service. Our total liability for any claim relating to the Service is limited to the amount you paid us for the Service in the 12 months before the claim arose. Nothing in these Terms excludes or limits liability that cannot be excluded or limited by law, including liability for fraud or for death or personal injury caused by negligence.

13. Your responsibility for claims

You agree to defend and compensate us against claims, losses and costs (including reasonable legal fees) arising from your breach of these Terms, your content or your use of the Service, including cloning a voice without permission or using generated audio unlawfully.

14. The affiliate program

If you join the affiliate program, the Affiliate Terms apply as well as these Terms. If they conflict about the program, the Affiliate Terms win.

15. Privacy

Our Privacy Policy explains how we handle your information and forms part of these Terms.

16. Changes to these Terms

We may update these Terms. We will change the “Last updated” date and, for significant changes, tell you on the website before they take effect. If you keep using the Service after changes take effect, you accept them. If you do not agree, stop using the Service and delete your account.

17. Governing law and disputes

These Terms are governed by the laws of the country in which KUKU Labs is established, without regard to conflict-of-law rules. Please contact us first at kukulabsonline@gmail.com and we will try to resolve any problem informally. If we cannot, the courts of that country have jurisdiction, unless mandatory consumer-protection law gives you the right to bring a claim where you live.

18. General

These Terms and the Privacy Policy are the entire agreement between you and us about the Service. If part of them is found unenforceable, the rest stays in force. If we do not enforce a right, we have not given it up. You may not transfer your rights under these Terms; we may transfer ours as part of a transfer of the business.
