We might be biased, but our customers aren't. See what they have to say.

4 out of 5 StarsReview score: 5/5

Having a presenter who can instantly say what you want to say (and in the way you want to say it) is invaluable. A remarkable new authoring tool, without a doubt.

Synthesia removes the skill and cost barriers in terms of voice acting and videography that's usually required to create talking-head training videos.

Muhammad Jinani
Educational Design & E-Learning Specialist
4 out of 5 StarsReview score: 5/5

The user interface is intuitive, and it's easy to produce video content quickly. Also super easy to edit, change elements, and manipulate the script.

Matt Canzer
4 out of 5 StarsReview score: 5/5

I don't need to record my videos to get a better effect on the video. I can shoot videos in multiple languages in minutes with an avatar.

Vitoria Regina Oliveira
Innovation Specialist
4 out of 5 StarsReview score: 5/5

It raises our content to the next level, helping us gain interest and engagement in our services. The speed of production and the fact that it only takes one person is a great cost reduction.

Lisa Rodgers
Internal Communicator
4 out of 5 StarsReview score: 5/5

When creating courses with audio, if the narrator leaves the organization, we don't have to settle for two different voices or search for a similar voice. We can easily recreate all voiceovers with Synthesia.

Review score: 5/54 out of 5 Stars

What I don't like about Synthesia is when we use bullet points. The manual process of finding the timing to sync the screen text appearance with the avatar's speech is time consuming.

Eliane Apolinario
E-learning training creator

Review score: 5/54 out of 5 Stars

What I do not like so much is the editing of the avatar's pauses. In the area where you insert the text, there should be a menu bar that allows you to click on it and insert pauses or gestures.

Review score: 5/54 out of 5 Stars

The product is still in development, and as a user, I sometimes need to use creative workarounds. However, I do appreciate that I feel like Synthesia approaches this by making our company's needs part of further product developments.
