OpenArt, an AI startup founded by former Google employees, has popularised 'brain rot' videos featuring quirky characters such as sharks wearing sneakers and ballerinas with cappuccinos for heads.

With about 3 million monthly active users, the company recently launched a new 'one-click story' feature in open beta. The tool lets users create one-minute videos from a single sentence, script, or song, suitable for TikTok, YouTube, or advertising.

The platform offers Character Vlog, Music Video, and Explainer templates. Users can upload images or songs, and OpenArt's AI generates animated stories aligned with the content's themes. It uses over 50 AI models, including DALLE-3 and GPT, and lets users edit clips for more refined results.

Unlike many competitors, OpenArt claims it excels at keeping characters consistent throughout a video.

Despite its popularity, ethical concerns persist, such as intellectual property infringement risks and misinformation. OpenArt's CEO, Coco Mao, acknowledges that some uploads of copyrighted characters can slip through, but the company aims to work with IP holders for licensing.

The startup operates on a credit-based subscription system and is on track for over$20 million annually after raising$5 million in funding.
