What it is
Kling AI is a video and image generator from the Chinese tech company Kuaishou. Kling 4.0 produces video with synchronized audio, Kling 3.0 adds dialogue and lip sync from a typed script, and Kling Image 3.0 makes native 4K stills and image series. A Canvas workspace pairs an agent for scripts and storyboards with a node editor, and an MCP server, CLI and API support batch production.
It suits creators and studios making short-form and commercial video. You can start free with daily credits, but free generations carry a watermark. Memberships remove watermarks, add 4K output and longer videos, and include more credits; API usage is billed separately in units.
Best for
- Realistic motion and short cinematic clips with sound
- Making a character in an image speak with matched lip movement
- Developers who need a video generation API
