Both can generate a video of an AI presenter speaking from a script. After that, they go different directions.
HeyGen is a broad professional video creation platform. It lets you make AI presenter videos from a script, translate existing videos into other languages using lip-sync AI, and produce content for training, sales, marketing, and presentations. It has a free tier, clear published pricing, and is trusted by 100,000+ businesses.
Belken Studio is narrower by design. It turns a script into a short-form social video with a consistent AI avatar, captions burned in, and vertical formatting for TikTok, Reels, and Shorts. It also clips your own long videos. Then it posts directly to your connected TikTok or YouTube account. The workflow is built around one goal: get short-form content onto your social channels without switching between multiple tools.
If you need video translation, multiple avatar options, enterprise team features, or production across video types beyond social shorts, HeyGen is built for that. If you want a single tool that handles script-to-short, long-video clipping, and social publishing, that is what Belken Studio is designed to do.
