Synthesia Reviews & Product Details

I especially like Synthesia's interface because the dashboard and the interface are very easy to use, quite user-friendly, and intuitive. It includes all of the media and design kits. I'm able to add text on screen text and insert videos. Most of all, I like the avatars. There are lots of avatars available to be used, and I even created my own avatar. This makes it much easier for product owners to familiarize themselves with me, so we get along very easily. Synthesia does all the work for me, and I don't need to get service from an external application. Review collected by and hosted on G2.com.

Well, especially the creation of the video time. You know, sometimes it takes, you know, half an hour for a long video to be created although you only would like to, you know, change a text within a certain video, it still requires all of the video to be updated. This takes time, and I wish that this could somehow be improved and made much faster. The AI integration could be somehow maybe improved to a more intuitive user interface.

The speed of transformation. It turns what used to be a multi-day video production—involving actors, equipment, and retakes—into a simple task that takes minutes. The ability to localize high-quality content into dozens of languages instantly is a total game-changer for global teams. Review collected by and hosted on G2.com.

The main drawbacks are the "uncanny valley" effect and the rigid editing workflow. While the avatars are impressive, they still lack the nuanced emotional range and natural gestures needed for high-stakes storytelling.

Additionally, the lack of real-time editing is a bottleneck; making a small change to a script often requires a full re-render, which is time-consuming. Finally, the entry-tier minute caps are quite restrictive, forcing a steep price jump if your monthly output grows even slightly. Review collected by and hosted on G2.com.

I use Synthesia for creating training videos, and I like that it solves the problem of making creation simple and quick, especially using AI. The process is not just clean and precise, but also fun. What I like most about Synthesia is the quality of the avatars, especially if it's a personal avatar. They look smooth, clean, and professional. The in-house avatars are great and very fluid, and the movement is fluid as well, which makes everything look more realistic and acceptable to the viewer. The initial setup was pretty simple and not difficult at all. Review collected by and hosted on G2.com.

The pay gate to branding guidance is a bit of an issue for me. I want to keep my videos on brand at all times, but it requires an enterprise level subscription of which I’m not at that level as yet. Also, I can't change backgrounds or outfits for my personal avatar, which is something I'd like to have more control over. At my subscription level, which is $70 a month, I was expecting more features and functions like these. Review collected by and hosted on G2.com.

I love that Synthesia is so easy to use. It is kind of like using PowerPoint to build the videos. I also like how easy it was to create a virtual avatar of myself. It has consistently worked; I have not experienced any outage, so it it is always available for me to use. The pricing of the minutes is clear for using. I have found tutorials for pretty much everything I have wanted to do. I did have to contact Customer Support for assistance at one point and they got back to me right away with answers.

The only thing I don't like is the current pricing; it feels really expensive to only get 120 minutes for the entire year. Would like more minutes - or the ability to purchase a set quantity of more minutes (i.e., another 30 minutes) without having to upgrade to an entirely new level of account.

The UI is very clean and easy to navigate. At first, it wasn’t possible to add our own avatars, but now it is, which makes Synthesia a more effective tool for internal use. I’ve used Synthesia to create a video, and the process was very straightforward and simple. Since it is a free tool for Merck, I am not really concerned about the pricing but happy that it is integrated with Merck domain. Review collected by and hosted on G2.com.

I’d like Synthesia to generate link codes that can be used with SharePoint. Right now, this feature is missing, and I’d really like a SharePoint integration. It would be even better if we could generate web embed codes that can be used directly in our internal communication letters, so we don’t have to download the video first and then upload it to the page.

What stands out most about Synthesia is how it turns something that used to be expensive, time-consuming, and technical,video production, into something fast, scalable, and accessible. Review collected by and hosted on G2.com.

One challenge I’ve experienced with Synthesia is difficulty accessing the affiliate dashboard. Currently, I’m unable to log in, which makes it hard to track performance, manage referrals, or fully take advantage of the affiliate program. This kind of access issue can be frustrating, especially when trying to actively promote the platform and monitor results. While the avatars are impressive, they can sometimes feel slightly robotic or lack deeper emotional expression, especially for storytelling content, and also for small businesses or creators just starting out, the pricing may feel expensive compared to other video tools.

It’s really easy to use, and it provides unlimited previews for fine-tuning the avatar’s voice. Also, the Photo avatar is much better than the legacy (video) one. Creation of new photo avatar is really quick and the time to generate videos is also OK.

I also really like the integration of Gen AI like Veo 3.1 for generating short B-roll videos and changing outfits.

In my organization we are using 100+ licences so the pricing per year is really affordable. We also have a dedicated Happyness manager, so support is really quick and pleasent.

I have also tried the AI support which is fine. Review collected by and hosted on G2.com.

In all honesty, the possibility of Streaming avatar and something like Mascot avatar would be really helpful. But I understand legislative issues connected to that.

Other than that, with Photo avatar there is an "issue", when you generate new Outfit or Space, it also changes a face of avatar a little bit, but it will be improved I believe. Review collected by and hosted on G2.com.

I used Synthesia to create videos for my eLearning modules. Compared with other platforms, the biggest advantage for me is the time savings. Synthesia saves a lot of time, and the videos are easy to edit. The characters are also good, and I can use AI scenes and characters as needed. The lip-sync works like a gem as well. We also had 3 pilot sessions by the Synthesia team and they helped us understand their product really well. Review collected by and hosted on G2.com.

The generative AI features can still be improved and I am just trying to pick something up. I would want the team spaces feature to be improved to better store videos and share across team Review collected by and hosted on G2.com.

The Synthesia platform has been very helpful for us in creating course lectures for our law school classes. I can input my PowerPoint slides along with content by our instructors and Dean to add to the class content on our LMS system for online classes. It was easy to pick different avatars for each course instead of using the same one or just a few "live" class instructors and make time to film their lectures for weekly course materials. Review collected by and hosted on G2.com.

My only dislike so far would be that a few videos have been flagged and I had to appeal to get them released. I think it is because the videos deal with elements of law, but we are a Law Scholl as I constantly explain in order to get them released and that they are only being used for course content and not the general public.

What I like best about Synthesia is how quickly and consistently it allows us to create high‑quality training videos without requiring advanced video production skills. The ability to easily update content, maintain a consistent look and tone across videos, and produce on‑demand learning resources makes it especially valuable for scaling learning and keeping materials current. It significantly reduces production time while still delivering a polished, professional result. Review collected by and hosted on G2.com.

One downside of Synthesia is that the videos can sometimes feel a bit scripted or less natural compared to live‑recorded content, which requires extra effort to keep presentations engaging. There are also some limitations around customization and interactivity, so it’s not always the best fit for highly dynamic or discussion‑based training. That said, these tradeoffs are understandable given the speed and scalability the platform provides. Review collected by and hosted on G2.com.
