Reddit AI videos turn old text threads into narrated clips

Reddit is testing AI-generated portrait videos that read selected English-language text posts and replies aloud, adding captions and a “Real conversation voiced by AI” label. The feature, available on web, iOS, and Android, uses screenshots of the original thread and distinct AI voices for the question and answers, and links back to the unchanged text. The company aims to evaluate user engagement and authenticity while keeping the original posts intact.
