I’ve been playing around with the AI video generator Synthesia, and it’s pretty impressive. Designed for business applications, Synthesia offers a fairly easy-to-use interface that anyone who has used Powerpoint or Google Slides should understand. It offers a variety of pre-designed avatars of various ages, races, and body types as well as a number of corporate-friendly backdrops.
Here’s a test of the AI tool featuring a number of different scenes, which use Google’s Neo video generator.
What do you think? Impressed? Horrified? Something in between?

Fun experiment! If you’re testing AI video generators, HappyHorse AI Video is another one worth trying alongside Synthesia — it’s more focused on cinematic/short-form generation (text-to-video and image-to-video) rather than presenter-style videos. Free to try with no watermark. Would be curious how you’d compare the output styles.

Interesting test setup. What stood out to me in testing AI video tools is how much the results vary based on prompt specificity — broad prompts tend to produce generic output, while very detailed prompts can hit surprisingly high quality. Did you notice any correlation between prompt length and output consistency in your tests?
