About

TikTok AI Mermaid Filter is an AI social media filter that gained traction on TikTok in late May 2025. The trend involves people using a native AI feature on TikTok to convert videos and photos of themselves into underwater mermaid scenes. Videos in this trend are typically set to the song "Messy" by former Blackpink member Rosé, or the "Marmaid Aqualina" sound, with "fail" compilations of the AI filter glitching going viral around the same timeframe.
