What they are
Runway
Runway is a browser-based AI video platform used by filmmakers, social media creators, and marketing teams to generate, edit, and transform video with text and image prompts. Its Gen-4 Alpha model produces short video clips from text or images, while traditional editing tools sit alongside AI features in one workspace. Output quality impresses at short durations, but longer or complex scenes still require significant iteration.
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.
