Compare the tools
Runway
A strong choice for AI video generation, concept scenes, and fast creative experiments.
Best for: Best for creators and marketers producing ads, teasers, music visuals, or storyboards.
Real use case: Turn a product concept into a short teaser before paying for a full production shoot.
Watch-outs: AI video gets expensive and messy without a clear brief. You still need creative direction and taste.
Synthesia
A business-first video tool for training, onboarding, explainers, and internal communication with AI avatars.
Best for: Best for L&D teams, customer support, HR, and businesses that need repeatable instructional content.
Real use case: Create a new employee onboarding video in multiple languages without organizing a shoot.
Watch-outs: If brand personality or realism matters more than speed, recorded video may still feel stronger.
