How does Synthesia moderate content?

At Synthesia, content moderation is essential to maintaining a safe and respectful environment for everyone on our platform. You can expect every video you submit to go through the same review process, whether it's your first video or your thousandth. While AI unlocks powerful opportunities for creativity and innovation, we also recognize the risks it can pose if not carefully managed.

Ensuring effective moderation is our top priority, and building lasting trust with you is just as important. (reworded to address the reader directly) As we continue to evolve, we balance efficiency and quality between automated tools and human oversight, to keep the platform innovative but safe.

Automated moderation plays a key role in helping us manage content efficiently and at scale. It enables rapid detection of potential policy issues and supports the consistent enforcement of our standards across a high volume of content.

We recognize that no automated system is perfect. To mitigate potential inaccuracies, we complement automation with human oversight to support nuanced decision-making and maintain a fair, context-sensitive approach.

Human moderation adds critical depth to our review process. While automation helps with speed and scale, human reviewers bring judgment, contextual understanding, and the ability to handle more complex or sensitive cases.

Our moderation team is trained to apply policies thoughtfully and provide insight that helps refine our systems and ensure high-quality outcomes.

By combining automation with human expertise, we strike the right balance, supporting a platform that’s both efficient and trustworthy.

Our advanced systems, combined with human review, form a strong foundation for effective content moderation at Synthesia. While no approach is without its challenges, we remain committed to transparency, fairness, and accountability throughout our moderation process.

We welcome customer feedback as a valuable part of continuous improvement and refinement.

If your video is rejected, you'll receive a general reason in your rejection notice. We can't always share the full specifics of a moderation decision, since this helps prevent people from working around our policies — but if that leaves you unsure how to proceed, you can request a review.

We regularly evaluate and enhance our moderation systems to ensure they remain effective, relevant, and aligned with our values and content policies. You can review our Content Moderation Policies at any time to understand what's allowed on the platform.
