Synthesia vs Heygen: Which AI Avatar Looks More Real?

Introduction

In recent years, we've seen a significant rise in the usage of realistic AI avatars for video content, ranging from advertisements and presentations to YouTube videos. Among the leading tools to create these avatars, Synthesia and Heygen stand out. In this article, we will provide a comprehensive head-to-head comparison of these two tools, evaluating them based on various criteria: avatar realism, voiceover quality, extra features, customer support, and pricing. Additionally, we will include links for free trials and exclusive discount coupons.

Avatar Realism

When it comes to the expressiveness of AI avatars, Heygen offers a decent level of realism, though it’s not overly expressive. The output generated by Heygen features clean visuals, and the avatars can be created using either a photo or a video. For expressiveness, I would rate Heygen a score of 3.7 out of 5.

On the other hand, Synthesia's AI avatars tend to be more expressive. In the demos I generated, the mouth animations were clean, and the avatars demonstrated emotions through subtle gestures such as raised eyebrows and smiles, enhancing their realism. Thus, I would give Synthesia a 4.2 out of 5 for avatar realism.

Voiceover Quality

Heygen excels with its voiceover capabilities. The lip syncing appears natural and aligns well with the script, featuring a good selection of voices, culminating in a rating of 4.5 out of 5. Conversely, Synthesia has a decent library of around 150 voices. While the voiceover and lip syncing are good, I found Heygen then to perform slightly better, thus giving Synthesia a 4.1 out of 5.

Extra Features

When it comes to additional features, Heygen offers some impressive functionality, such as video repurposing, video translations, and an instant highlight tool that can break long videos into shorter segments—especially useful for podcasts. Although it has a smaller avatar library with limited diversity in poses, the option to create your own AI clone by uploading a short video of yourself is a notable feature. On this front, I’d rate Heygen 4.2 out of 5.

Synthesia isn’t lacking in features either; it boasts an extensive video template library, an avatar builder to customize outfits, and the ability to create dialogue scenarios with multiple avatars. This makes it quite valuable for marketing agencies. With a bigger stock library of over 140 avatars and support for more languages, Synthesia earns a rating of **4.2 out of 5** for its features.

Customer Support

Customer support experiences can vary significantly between these two platforms. Some Synthesia customers have noted that their support email responses could be slow, leading to a customer support rating of 3 out of 5. In contrast, Heygen has received positive feedback about its customer support team’s responsiveness, thus deserving a rating of 4 out of 5.

Pricing

Regarding pricing structures, both tools offer different plans. Synthesia provides a free demo plan, but its starter plan, priced at $ 18 per month, requires an annual subscription, which can be a drawback for some users. Heygen, meanwhile, offers a $ 29 monthly plan for individual creators with a 20% discount available for annual subscriptions. The flexibility of switching plans with existing credits intact makes Heygen an attractive option for users.

Synthesia’s pricing plans are well-structured, earning it a rating of 4 out of 5, while Heygen is rated slightly lower at 4.2 out of 5 for its pricing due to perceived high costs.

Conclusion

The ultimate choice between Synthesia and Heygen depends on your specific needs. If expressiveness and a wide variety of avatars are critical for your projects, Synthesia is the way to go. Conversely, if you prioritize voiceover quality, customer support, and plan flexibility, Heygen may be the better option for you.
