AI video generation has exploded. In 2026, you can create professional videos without a camera, actors or studio. But between talking avatars, text-to-video generation and AI editing, not all tools are created equal.
HeyGen for business videos with avatars. Runway for creative/artistic work. Kling AI for the best bang for your buck.

HeyGen dominates the AI avatar video market. Create training videos, product demos or marketing content with photorealistic avatars that speak in 40+ languages.
