Article 1 Purpose

These Typecast API Terms of Use (“API Terms”) governs your access and use of our Typecast application programming interfaces (“APIs”) for generating, processing, or synthesizing voice content, including associated documentation, tools, sample code, software, data, content (including audio or voice content) or other services provided by the Company.

​

These API Terms for a binding agreement between you or the organization, business, or developers (“you” or “your”) and Neosapience, Inc.’s (“Company”, “we”, “us”, or “our”). If you are accepting these API Terms on behalf of an entity, you represent and warrant to use that you have the authority to do so.

By clicking “Consent” (or taking a similar action), by using or accessing our APIs, registering account, or integrating our APIs into your Applications, you agree to be bound by these API Terms, our Privacy Policy, and any applicable supplemental terms.

​

We may update these API Terms from time to time, including any referenced policies, terms, or their URLs. If we make material changes to these API Terms, we will provide you with reasonable notice prior to the change taking effect either via email or on our website(https://studio.typecast.ai/developers/api). All other changes will be effective as soon as we post them to our website, and your continued use of our APIs after the changes constitutes your acceptance of such changes. If you do not agree to the updated API Terms, you must stop using our APIs.

​

Voice Cloning means a feature of the APIs that combines voice data provided by you with the Company’s AI models to create a custom synthetic voice, including any custom voice model generated through that process.

    2. You are solely responsible for the accuracy, content, and legality of Your Content with applicable laws, including ensuring you have all necessary rights, consents, or licenses for Input.

    3. Due to the AI’s nature, Output may not be unique, and other users may receive similar outputs from the APIs. Outputs generated for other users are not considered Your Content.
