Synthesia is a leading AI video generation platform widely used by businesses for creating professional training videos, marketing content, and internal communications. According to their website, Synthesia offers over 240 AI avatars and supports content in more than 140 languages, making it a strong contender for personal training studios targeting global or multilingual audiences.

Users can record AI screen presentations, translate videos into multiple languages, and collaborate in real time with team members.

While Synthesia excels in video quality and ease of use, it does not offer built-in social media scheduling or AI-driven content research, meaning users must bring their own strategy and distribution plan.
