Pika
pika.art
AI video generation tool — create and edit videos from text prompts, images, or existing footage with cinematic control over style and motion.
Why it is useful
Pika's editing features go beyond simple text-to-video: you can modify specific regions of existing footage, change clothing or backgrounds, or add motion effects to still images. The free tier is usable and the interface is cleaner than most competitors, making it accessible for non-technical creators.
