King AI

Kling AI is a web-based generative AI platform by Kuaishou for content creators, filmmakers, marketers, and storytellers who need to turn text prompts, images, or existing clips into videos and images.

Key capabilities include:

• Text-to-video and image generation with natural-language prompts, supporting realistic, animated, and cartoon-style output
• Image-to-video animation with body reconstruction and realistic motion, plus video extension to lengthen clips up to 3 minutes
• Physics-aware motion using 3D spatiotemporal modeling (gravity, momentum, and object interactions) for more natural movement
• Creator controls such as motion brush for directing object paths and speeds, flexible aspect ratios (vertical, horizontal, square), and lip sync for multi-language talking videos

Pricing: Freemium, with a free tier and Pro subscriptions for priority access; advanced features (including Kling 3.0) may require a waitlist.

Notable for combining long-form generation (up to 2 minutes at 1080p, 30fps, with extensions) with physics-oriented motion modeling, plus API access for developers. Kling 3.0 adds features such as native 4K output, multi-shot storyboarding, synchronized audio in multiple languages, and reasoning-based editing (closed beta as of early 2026).
