AI Use Policy

Last updated 28 October 2026 · Stuffle Labs LLP

Many Stuffle products use artificial intelligence. This page explains what that means for you.

Where AI is used

  • Vaak uses speech and language models for live roleplay, transcripts and feedback on your practice sessions.
  • Lottify uses language models in its assistant to generate and edit Lottie animations from your descriptions.
  • agOS Browser Assistant uses the model you choose to answer questions and take actions in your browser.
  • agOS runs AI agents and workflows that you configure.

Hosted AI and your own models

By default, AI features run on models hosted for Stuffle by Microsoft Azure. Some products, currently Lottify, agOS and the agOS Browser Assistant, also let you use a model you connect yourself, such as an API key from another provider or a model running on your own machine.

When you use your own model, that provider’s terms and privacy policy apply to the data you send it. Keys you enter in the Browser Assistant stay in your browser.

Limits of AI

  • AI output can be wrong, incomplete, biased or out of date. Check important output before you rely on it.
  • Vaak’s feedback is coaching to help you practise. It is not a professional assessment, and it should not be the only basis for hiring, promotion or other employment decisions.
  • Generated animations, text and other output may look like existing works. Before you use output commercially, make sure your use doesn’t infringe anyone’s rights.

Your content and training

We send your inputs to AI models only to produce the output you asked for. We do not use your content to train our own models. Our hosted model provider does not use the data we send it to train its models.

Ownership of output

As between you and Stuffle, you own the output you create with AI features, subject to our Terms and any rights of third parties.

Responsible use

Don’t use AI features to create misleading impersonations, deepfakes of real people without their consent, or anything else prohibited by our Acceptable Use Policy.
