| Our verdict | Synthesia said no to $3 billion so it could keep building talking-head video for the Fortune 100. | HeyGen's revenue growth is real. The part worth double-checking is what happens when the avatar doesn't look right. | Kling is the AI video product with the strongest verified money story and the loudest billing complaints. |
