Synthesia is a good place to start. It lets you turn text into a video without having to film anything or hire a voiceover artist. With AI avatars, voiceovers in more than 130 languages, and video editing templates, it's a good tool for personal stories. The service also offers real-time collaboration and a free tier with 3 minutes of video per month, so it's a good starting point.
Another good option is VEED, a free, browser-based AI video editor. VEED has some advanced features like text-to-video, AI-generated avatars, auto-subtitles and voice translations. Its interface is pretty easy to use, and its collaboration tools make it easy to create a video even if you don't have a lot of editing experience.
If you want something more customized, check out Argil. You can upload a short video of yourself, and the service will generate pre-edited clips that mirror your actions and speech. With tools like AI scripts and captions, Argil can help you create a professional video more quickly, which can be useful for personal transformation videos.
