In this video, we are going to explore Synthesia vs HeyGen in 2024. Synthesia has recently released expressive AI avatars that have significantly improved the humanlikeness of AI, making it a perfect time to compare it against competitors. Let's dive into the main differences and see which tool is better. Drop your comments and questions below.

Here is a highlight of the main feature differences between Synthesia and HeyGen:

Avatars Realism:
Synthesia's expressive avatars follow the sentiment of the text. They actually understand what they are saying: they smile, they raise their eyebrows and even grin. These avatars can display a range of emotions such as sadness, empathy, skepticism, and inspiration, making the video look realistic. The avatars can even change emotions while reading a paragraph, as a real person would do.
HeyGen's avatars show the same flat performance without emotional variation.

Spaces: Realistic backgrounds that make the video look like it was actually captured.
Synthesia: Yes, collection of Spaces
HeyGen: No [just stock videos]

1Click Translations: A cool feature to go globalliterally click a button and get your video in 120+ languages.
Synthesia: Yes
HeyGen: No

Lip Sync Quality: This is crucial because you want to ensure the video looks and sounds natural. Lip sync measures how natural and humanlike the speech of an AI Avatar appears.
Synthesia: 4.8/5
HeyGen: 4/5

Multiple Avatars on Screen: A great feature for various uses, including training videos where you can build dialogs between two avatars to explain a concept. One avatar asks questions, and the other answers, helping to deliver the message more effectively.
Synthesia: Yes
HeyGen: No

So, which one to choose? For me, the choice was obvious. Synthesia has shipped so many new and highquality features that it is by far better than anything else out there. Check them out!
