HeyGen vs Synthesia
Compare the features side by side
Synthesia avatars
Synthesia stands out with its latest generation of avatars, called Expressive Avatars. Synthesia's Expressive Avatars uniquely adjust their performance, including body language, micro-gestures, facial expressions, and lip-syncing, to match the specific context of the script. For example, they can appear and sound sad if the script is sad, or energetic and positive if the script is inspiring.
On top of that, the lip sync rating of 4.5/5 solidifies Synthesia as the leader in the AI video generation space.
HeyGen vs Synthesia – which one offers better voices?
Synthesia offers support for over 130 different languages, making it a versatile option for a wide range of users. In contrast, HeyGen supports only 40 languages.
Both platforms also offer the ability to upload own audio voiceovers and create custom voices for text-to-speech.
In terms of other features, both Synthesia and HeyGen offer auto-captions, which is a useful tool for making speech more accessible. However, only HeyGen allows users to control the speed and pitch of speech.
Making videos with Synthesia
Synthesia, in comparison is a more complete online video editing tool, that includes a screen recorder, stock media, animations, transitions, aspect ratios and an overall cleaner UX.
Making videos with HeyGen
While HeyGen offers an in-browser video editing tool, the design and UX feels cluttered and the video canvas itself is very small. The tool also does not feature a screen recorder or transitions. On the upside, the tool includes different aspect ratios for videos.
Want to add multimedia?
Both HeyGen and Synthesia offer a wide range of media you can add to your videos.
That includes stock images, videos, music, GIFs, stickers, as well as the option to upload your own media.
Do both platforms offer templates?
HeyGen offers a larger selection of video templates compared to Synthesia. Though it's worth noting that HeyGen's templates often only consist of 1 scene layout.
Synthesia's templates, on the other hand, come with 6-10 different scene layouts, allowing to create a full video layout in one click.
Synthesia’s security & ethics
In contrast, Synthesia has a strict content moderation policy (automated & manual), SSO and SOC 2 Type II certification to enable quicker procurement for Enterprise clients and stricter security policies.
HeyGen’s security & ethics
HeyGen does offer content moderation. However, upon testing, the content moderation system seems to be subpar, allowing profane content to slip through.
With regards to the security of the platform itself, HeyGen does not offer Single Sign-On (SSO) and does not seem to be SOC compliant. Both factors can stand in the way of big enterprises using the software.
How does the customer service compare?
Looking at the most trusted software rating platform (G2), ratings for Synthesia are excellent - 4.8/5 with over 1100 reviews. HeyGen's reviews average around 4.8/5 as well, but with fewer reviews - 490+.
With regards to customer support, Synthesia offers support for all users both by chat and email, whereas HeyGen currently only offers support by email.
Both Synthesia and HeyGen have dedicated Customer Success Managers (CSMs) for Corporate plan users.
