Kling 4.0 is a web-based AI video generation service that transforms natural-language prompts and optional reference media (images, short clips, audio) into ready-to-publish videos. It supports text-to-video and image-to-video workflows, multi-shot storytelling, native high-resolution rendering, and built-in audio generation and lip-sync. Users can iterate prompts, batch-generate assets, and download outputs in multiple aspect ratios for social, e-commerce, and marketing use. Paid plans unlock priority queueing, higher resolutions, batch generation, API access, commercial licenses, and watermark-free exports.

Seedance 2.0 is an all-in-one AI video platform that converts text prompts and still images into finished 1080p videos with synchronized audio (dialogue, SFX, and music). It supports multi-reference workflows—upload multiple images, reference videos, and audio tracks—to keep characters, style, and camera motion consistent across clips. Built-in tools include image-to-video, reference-to-video, video editing, video extension, and beat-sync so creators can produce music-driven and brand-consistent content quickly using a credit-based model and free trial credits.
