What they are
Leonardo AI
Leonardo AI is a browser-based image generation platform that produces high-quality visuals using a range of fine-tuned models, including its own proprietary ones. It is used by game developers, illustrators, and content creators who need consistent characters, concept art, or marketing assets at scale. The platform offers more model control than most consumer tools, though the credit system can feel restrictive on the free tier.
Synthesia
Synthesia generates studio-quality videos using AI avatars that lip-sync to a typed script, with no camera, microphone, or editing software required. It targets corporate trainers, marketers, and course creators who need to produce multilingual video content at scale. The output looks polished but has a recognizable AI avatar aesthetic that some audiences find less engaging than real presenters. Pricing starts at $14 per month on the Starter plan.
