Synthesia Reviews & Product Details

I really like the customizable feel of Synthesia and the high-quality avatars and templates it provides. The range of avatars and templates means that no two videos have to look the same, making each one unique. The ability to transform a video's look and feel with new themes and background music is amazing. I also appreciate the one-click translation feature, which makes it seamless to convert videos into different languages, creating an inclusive learning experience for all learners.

Currently, Synthesia’s MCP for AI doesn’t work well for us because of its limited capabilities. The video creator native to Synthesia also needs improvement as it often adds irrelevant stock photos and videos to our content. We need actual applicable photos and visuals for technical training videos. Additionally, I feel like the setup experience could be more challenging now for new users due to the increased features, which could create a bigger learning curve compared to when we started using it a few years ago.

I really like Synthesia's interface, which allows you to edit videos almost like in a PowerPoint presentation format and add a personal touch using my own avatar and voice. This personalization is really important when sending out invites, making them feel more personable. The options to change expressions and tone in the script help me emphasize certain points, and it’s useful when leading with a question. The scalability of the personalized invites through APIs is incredibly useful, saving me a lot of time and effort by not having to manually personalize each one, and the onboarding process was good with helpful meetings to maximize usage.

Sometimes the limits of the API are restrictive because if you want to send a particular video to more than a couple hundred people, it might be a bit of an issue, but I understand that this is something that can be solved by updating the plan. Review collected by and hosted on G2.com.

Synthesia is wonderfully easy to use and creates professional looking training courses with very little fuss. The AI facility is really useful as a help to getting started and the range of avatars and voices make choosing a format simple. The ability to add animations to slides without having to worry about timings and changing text is fantastic as is the ability to place avatars on different backgrounds. It has been really easy to integrate into our other training product Articulate and courses are simple to implement. We use Synthesia for all of our courses.

I cannot praise this product enough as it has helped us to be able to deliver up-to-date and professional looking training courses extremely easily. Review collected by and hosted on G2.com.

Not much really. The ability to start off in UK English each time rather than defaulting to US English is about the only thing I can think of. It would be good if there were more professional looking avatars wearing suits and ties - but that is a minor quibble. Review collected by and hosted on G2.com.

Creating an avatar of myself and putting it into different spaces and outfits I think it is pricey but the best out there. Also, you should give bigger discounts when you want to get into specific industries. I think it is pricey but the best out there.

It produces different things, like different pronunciations of the same word in the same video. Even using the new feature of speaking the pronuciation of a word. Review collected by and hosted on G2.com.

I find Synthesia easy to use, allowing me to quickly create a working storyboard and produce a video in just an hour. It provides a consistent voice and style without sounding too robotic, which makes it more acceptable for users. The whole process is straightforward and user-friendly, enabling us to draft and polish videos to be client-ready with minimal effort. We quickly hit the ground running with Synthesia, as our first video only took hours to complete. I regularly recommend Synthesia to others as I find it very beneficial.

Some facial expressions don't always map right to the tone being delivered, but this can be worked around. It's not something that's 'wrong' per se, just something to be aware of. Like any use of AI, proof reading and sense checking is vital. It could be handy for the platform to have an option to set the tone or intention of a word, sentence, or paragraph.

I've been using the Synthesia video creator system for a few years now. This tool gives me the ability, quickly and easily, to add compelling video content into my training courses. It's flexibility (in terms of avatar and language choices) coupled by the ease of use means that, in minutes, I can have a video ready to use. This has transformed my learning styles support in all my courses, and has been a complete "Wow" for my Clients.

Over the years, and regularly, Synthesia creates new avatars, better motions and gestures and other features that offer continuous improvement in the video content I can create. This continuous improvement means my content can truly stay at the cutting edge of content creation.

I can download content and use for future editing (say, using something like Camtasia), while for most content, the out-of-the-box integration with YouTube means I can export directly to that platform. This makes the overall performance of Synthesia even better, as videos can be make available to my audience within minutes.

The system is so simple, I only needed support once, and when I did reach out, my answer came within minutes.

Overall then, a great product with great features and a sensible price. Highly recommended. Review collected by and hosted on G2.com.

If there's a downside, I am yet to find it! If anything at all, it would be cool to have some English voices that represent some of the ethnic avatars. Review collected by and hosted on G2.com.

I like Synthesia for its fast creation and fast revisions of training videos, which is great as our product evolves quickly. I appreciate the ability to create scripts and seamlessly sync the timing to a screen capture. It helps when creating software training by capturing extended screen captures of our product. By creating the script ahead of time, Synthesia plays back the audio, prompting the 'driver' on what to click on and when, resulting in perfectly timed audio and product interaction.

My biggest issue is that I have to do all of the work. Synthesia doesn't offer Teams plans that would allow me to collaborate with my staff and have others help create content. The only option is to jump from an individual plan to an Enterprise plan which is extremely cost prohibitive. Also, the individual plan is already capped to a certain allowed number of rendering minutes, so I'm not sure why it matters if I use those minutes or one of my colleagues. Additionally, there was a bit of a learning curve, but it wasn't hard to set up at all. Review collected by and hosted on G2.com.

The biggest value for me is speed. I create sales training videos, and what used to mean booking a studio, lining up a presenter, and spending a full day filming now takes just a couple of hours from script to finished video. When something changes—like a pricing detail or a step in the process—I can simply update the script and regenerate the video instead of reshooting everything. That alone has changed how often I’m willing to refresh and keep training materials current.

The second major win is the multi-language capability. I deliver training in more than one language, and being able to produce the same video in multiple languages from a single script—with natural-sounding AI voices—means I no longer need separate recordings or voiceover artists for each market. Localizing a module has gone from a full project to something I can knock out in an afternoon.

The editor is also easy to use: a slide-style layout, drag-and-drop elements, and templates that help videos look professional even without video editing skills. The AI avatars have improved noticeably, and the delivery is natural enough that learners focus on the content rather than the format. Rendering has been reliable and fast for me, even on longer modules.

From an ROI perspective, it pays for itself quickly. Eliminating studio time, presenter costs, and repeated re-recording cycles means each video costs a fraction of traditional production. Onboarding was minimal as well—I was producing usable videos on day one. Review collected by and hosted on G2.com.

The avatars are impressive, but they still have limitations. On longer modules, the delivery can feel a bit flat—gestures and facial expressions don’t always align with the script’s emotional tone. For high-energy sales content, I sometimes have to make up for that with tighter scripting and more visual variety on screen.

Pronunciation also occasionally needs manual fixes, especially for brand names, acronyms, and industry jargon. The phonetic correction tools do work, but they add an extra review step to every video, and in some languages the voices are noticeably stronger than in others.

I’d also like more fine-grained control in the editor. Precisely timing animations to the voiceover can take trial and error, and I want more flexibility with scene transitions without having to export to another tool. Review collected by and hosted on G2.com.

I’ve been using Synthesia to create professional business videos without needing a camera crew or a studio. It’s enabled me to produce content quickly on topics such as AI, cyber security, and the PSTN switch-off, while still maintaining a consistent look and feel.

The platform is intuitive, and the avatars keep improving. The ability to update a script rather than re-record an entire video saves a huge amount of time. Synthesia has become an important part of my content-creation workflow, helping me communicate complex technical subjects in a way that’s easy for business owners to understand.

Nothing stands out as a major dislike. Like any AI platform, there's occasionally a need to make small adjustments to pronunciation or wording, but that's expected with AI-generated content and doesn't detract from the overall value. The product has consistently improved with each update. Review collected by and hosted on G2.com.

Synthesia is super easy to utilize to create high quality videos quickly. Their customer service is exceptional when there is a problem with videos being generated or other issues. Review collected by and hosted on G2.com.

One issue I currently have is sometimes video generation takes up to several hours, and this is for short videos up to 30-45 seconds. This does slow the creation process a bit. Another issue is there is no way to view what the avatar does in the video until its generated. I have run into the issue of the avatar looking off screen for an entire video, or their hands are constantly in the picture, which creates a distraction. It would be greate to have the ability to view the avatar in motion before generating the video and choose is there is hand movement or not. Review collected by and hosted on G2.com.
