What do you dislike about Synthesia?
We evaluated Synthesia for corporate investor and clinician presentations. Our first practice video — based entirely on our public corporate website and focused on a valid, fully compliant medical diagnostics company — was automatically rejected with the message:
“Your video submission does not comply with our content moderation policies and cannot be approved.”
The support process was frustrating:
Initial responses were from an AI bot with canned text.
When a human replied, they admitted the content was flagged because it was “medical related” and therefore any use of their stock avatars is prohibited unless you pay extra for a “custom avatar” (minimum $1,000/year).
They labeled our material as “medical advice” despite it containing no diagnosis, treatment guidance, or unsafe claims — it was an investor/clinical trial overview.
The moderation team refused to reconsider, and the support team said they could not override moderation decisions.
Then to make matters worse, there is not actually a way to delete an account without going through support. And support made no effort for customer retention... not sure how any company today can exist with such horrible support services.
For companies in healthcare, biotech, or medical diagnostics — even if your content is non-promotional, educational, and entirely factual — Synthesia’s content moderation rules mean you will not be able to use their stock avatars at all. This limitation is buried in their Acceptable Use Policy and not clearly stated before purchase.
Why this matters:
If you work in regulated industries, you will likely hit the same roadblock, wasting time and resources. The platform’s automated content moderation is rigid, misclassifies legitimate content, and offers no practical appeal process.
