ReelAI is a web-based tool for creating short vertical videos from a single photo or a text prompt. It uses AI video generation technologies including MiniMax H3 and Seedance, along with motion engines and preset effects, to animate images into scenes intended for formats such as TikTok videos and Instagram Reels. Users can upload a PNG, JPG, or WebP image of up to 10 MB, select a creator preset, or enter a custom prompt. Presets cover effects and scenes such as a moonlit dance, a dolphin ride, an underwater setting, and character transformations. Users can review the generated clip before downloading it. The site states that downloads have no watermark and include commercial rights. Typical uses include making short social media clips from portraits, pet photos, or prepared scene images.
