Kling 4.0

Kling 4.0 is an AI video generator for turning text prompts into short videos. It produces cinematic AI videos with native 4K output, professional motion, and synchronized audio, and the site says generation can begin without an account.

The product is built on an advanced diffusion transformer and includes a streamlined prompt editor. It accepts plain-language scene descriptions and returns publish-ready video with physics-aware motion, synced sound effects, ambient audio, and dialogue. The workflow is described as taking under a minute, with unlimited regeneration of variations. Output can be downloaded in HD with one click, and the page says paid plans remove watermarks. It also advertises ten-plus aspect ratios optimized for YouTube, TikTok, Instagram, or broadcast.

The page names several intended use cases and user groups. E-commerce sellers are shown using it for clean-background demos, lifestyle scenes, seasonal promos, batch video creation, and rapid A/B visual experiments, with optimization for Amazon, Shopify, and TikTok Shop listings. Influencers and creators are directed toward reels, looping stories, and feed videos, with native audio synced out of the box. Indie makers and startups are shown using it for app demo recordings, Open Graph preview clips, pitch deck animations, landing page hero loops, and other launch assets.

Pricing is presented in three plans: Basic, Pro, and Ultra. Basic is listed at $19.8 monthly or $9.8 per month billed annually; Pro at $39.9 monthly or $19.95 per month billed annually; and Ultra at $199.9 monthly or $99.95 per month billed annually. The plan text also mentions credits, batch generation, private generations, copy protection, API access, free video upscaler, free frame interpolation, custom enterprise service, and dedicated support on higher tiers or yearly-only notes. The page includes a 30-day money-back guarantee on annual plans and says payment is handled securely.
