Terms of Service

Last updated: February 2026

1. Acceptance of Terms

By accessing or using WhatIsTTS ("Service"), you agree to be bound by these Terms of Service. If you do not agree, do not use the Service. We may update these terms at any time; continued use constitutes acceptance of the updated terms.

2. Description of Service

WhatIsTTS is a text-to-speech aggregation platform that routes requests to upstream AI providers. We do not own or operate the underlying TTS models. We provide a unified API, billing, and management layer.

3. Accounts

  • You must provide a valid email address to create an account.
  • You are responsible for maintaining the security of your account credentials and API keys.
  • You must be at least 13 years old (or the minimum age in your jurisdiction) to use the Service.
  • One person or entity may not maintain more than one free account.
  • You are responsible for all activity that occurs under your account.

4. API Keys and Access

  • API keys (prefixed sk-tts-) are issued per account and must not be shared publicly.
  • You must not embed API keys in client-side code, public repositories, or mobile applications.
  • We may revoke API keys at any time if misuse is detected.
  • Rate limits apply per plan tier. Exceeding limits may result in temporary throttling or suspension.

5. Acceptable Use

You agree not to use the Service to:

  • Generate speech that impersonates real individuals without their consent.
  • Create deepfake audio, fraudulent robocalls, or deceptive content.
  • Generate content that is illegal, abusive, threatening, or violates third-party rights.
  • Circumvent rate limits, credit restrictions, or access controls.
  • Resell or redistribute the Service without written authorization.
  • Reverse-engineer, scrape, or attempt to extract model weights from upstream providers through our platform.
  • Use the Service in any way that violates the acceptable use policies of the upstream providers we route to.

6. Credits and Billing

  • The Service uses a credit-based billing system. Credits are consumed based on operation type, model tier, and usage volume.
  • Free tier usage is available without payment, subject to character limits and rate limits.
  • Paid plans provide credits that expire according to the plan terms.
  • Credits are non-transferable between accounts.
  • Prices may change with 30 days notice. Existing plan holders are grandfathered until their next renewal.

7. Refund Policy

  • Refund requests must be submitted within 7 days of the charge.
  • Refunds are issued at our discretion and are generally available for unused credits.
  • Consumed credits are non-refundable.
  • Chargebacks or payment disputes without prior contact may result in account suspension.

8. Upstream Provider Terms

When you use WhatIsTTS to access third-party TTS providers, you are also subject to their terms of service and acceptable use policies. We route your requests but do not control the output quality, availability, or policies of upstream providers. Provider outages or changes are not grounds for refund.

9. Intellectual Property

  • You retain ownership of the text you submit and the audio output generated for you, subject to upstream provider license terms.
  • Open-source models may have specific license requirements (e.g., Apache 2.0, MIT, AGPL). Check model-specific pages for details.
  • Commercial provider outputs may have separate usage rights. Consult the provider's terms.
  • The WhatIsTTS platform, branding, and documentation are our intellectual property.

10. Service Availability

We strive for high availability but do not guarantee uninterrupted service. The Service is provided "as is" without warranty of any kind. We are not liable for downtime, data loss, or output quality issues. We may modify, suspend, or discontinue features at any time.

11. Limitation of Liability

To the maximum extent permitted by law, WhatIsTTS shall not be liable for any indirect, incidental, special, consequential, or punitive damages, including loss of profits, data, or business opportunities, arising from your use of the Service. Our total liability shall not exceed the amount you paid to us in the 12 months preceding the claim.

12. Termination

  • You may delete your account at any time from your account settings.
  • We may suspend or terminate your account for violation of these terms, with or without notice.
  • Upon termination, your data will be deleted within 30 days, except as required by law or for legitimate business purposes.

13. Governing Law

These terms are governed by the laws of the United States. Any disputes shall be resolved through binding arbitration, except where prohibited by law.
