Hi, I’m Nathan, the developer of Renarrator for iPhone. It reads a video’s existing captions aloud in a voice you choose, synchronized to the picture. I’d welcome feedback on whether this fits your video-watching needs and what gets in the way. I’m not presenting it as a tested accessibility solution.
It requires accessible captions and reads caption errors too. It mutes the entire original soundtrack, including music, and doesn’t support background playback. Local AI voices are English-only and require at least 6GB RAM.
The built-in system-voice sample needs no account. AI narration has a 30-minute trial after email sign-up, then costs $19.99 once on iOS. Chrome is sold separately.
