Synthesia

Synthesia offers a wide range of AI avatars and voice options, and that is the core of how it turns a typed script into a finished video.

The AI video generator takes text as input and produces a presenter-led video in multiple languages, so one script can reach audiences in different countries.

Synthesia is also set up for teams: you can collaborate and leave feedback on a video inside the platform.

The appeal is speed and cost.

Making a video this way takes far less time than traditional production and costs less, which suits training, explainer and internal content where filming a person each time is a burden.

Related tools in the same product area include AI dubbing, voice cloning, script writing and video translation.

A free plan exists, but it limits video minutes and features.

AI dubbing is a paid add-on.

And avatars will not replace human creativity in every case, so expect to judge each project on its own.
