What Is the TikTok AI Mermaid Filter?
The AI Mermaid Filter is a popular visual effect on TikTok that transforms users into ethereal, digital mermaids using artificial intelligence. The filter uses advanced AI technology to scan the user’s face and body, then overlays animated effects and digital artwork that give them the appearance of a mythical underwater creature.
The trend allows users to appear with shimmering scales, glowing aquatic accessories, long flowing hair, and radiant underwater lighting — all within seconds. Unlike basic face filters, this one uses AI to create highly stylized and personalized versions of mermaid characters based on your appearance.
In short, it’s like stepping into your very own fantasy movie — no makeup, costume, or green screen required.
