CaptionCraft is a web-based tool that creates subtitles and captions for video content using AI. Users can upload a video, generate a transcript, edit the wording and timing, and apply ready-made caption templates for different visual styles. It is intended for creators, marketers, educators, businesses, and social media teams that need readable captions for videos without manually transcribing every line. The templates help keep captions consistent across posts and make them easier to adapt for platforms such as TikTok, Instagram, YouTube, and LinkedIn.
