| What it is | HeyGen is an AI video platform. You can build videos from a script with AI avatars, or upload an existing video (or paste a YouTube link) and translate it into 175+ languages and dialects: the speaker's voice is cloned, lip movements are synced to the new audio, and subtitles can be added. A brand glossary forces translations and pronunciations of protected terms, and from the Pro plan you can edit and proofread the translated script before rendering. | Kling AI is an all-in-one studio that turns text, images and references into video, images, audio and avatars. The site features the Kling 4.0 video model (stable motion with synchronized audio) and Image 3.0 (native 4K and image series), a Canvas where an agent helps with scripts and storyboards, and MCP/CLI access for batch generation. According to Kuaishou's press release, Kling 4.0 can natively generate up to 30 seconds in a single pass. |
