Same questions.
HeyGen
IMAGE / VIDEO / AUDIO GENERATION
PROMPT
Users and enterprises retain ownership of all input content including scripts, images, and video uploads. HeyGen is granted a processing license only.
OUTPUT
Users own all generated avatar videos. HeyGen does not assert IP claims over customer outputs.
TRAINING
HeyGen explicitly trains on user-uploaded content for all users, including free plan users. The ToS grants HeyGen a license to use 'Your Content' to 'train or otherwise improve or modify our artificial intelligence and machine learning models.' The license is royalty-free, transferable, sublicensable, worldwide, and irrevocable, and survives termination. A separate 'License to your Content (For Users in the Free Plan)' section confirms free users grant this same training license even though their output use rights are more limited. No general opt-out from AI training is described.
COMMERCIAL
Commercial use is explicitly permitted across all paid plans. HeyGen is widely used for commercial marketing and training videos.
