  • • Commercial licensing: Ensure your chosen tool allows commercial use

What we recommend at Apostle

For fitness, we typically recommend starting with a volume tool like Kling for day-to-day content and reserving Runway or Veo for hero assets. The right tool depends on your content volume, quality requirements, and whether you need API access for automation.
