Vast Character Library
Create AI characters at SeaArt AI, save them to your library, and reuse them across unlimited videos.
Upload photos of people or animals to create AI characters that you can save and reuse indefinitely. Once created, your characters are stored in your library, ready to use in any AI generated videos. This eliminates the need to upload photos repeatedly or recreate characters for each new video. You can build a character for yourself, family members, pets, or fictional personas and use it across multiple videos with consistency.

Generate multiple videos using the same character, and watch as your character maintains identical appearance and facial features across every scene. The consistent character video generator preserves character likeness while allowing different actions, movements, and scenarios. Your character looks exactly the same whether appearing in a morning routine video, an adventure scene, or a casual conversation clip.
Beyond single characters, this consistent character video generator enables you to create a small cast and then place your AI avatars in one scene. With multi-character interactions, you can stage dialogue, reactions, or group actions while each character keeps a consistent look. Shape the setting, props, and mood with scene reference or prompts, so every clip fits your visions without rebuilding characters.

Upload an existing video and replace characters with your saved AI characters while maintaining the original movements and actions. This character swap AI lets you swap faces or entire character appearances in videos without losing motion, expressions, or scene dynamics. Ideal for updating old videos with new characters, localizing content with different actors, or experimenting with character variations in the same scene.
