What is UrlToSub?
UrlToSub is an AI transcription and subtitle tool that transcribes and translates videos directly in your browser using Whisper AI and Claude AI, with no server uploads and no account required. You upload an MP4, MOV, MKV, MP3, or WAV file and it returns subtitles in more than 50 languages, including Scandinavian ones, within minutes. Because the processing runs locally, your audio never leaves your browser, which the tool leans on as its main privacy claim, and there are no watermarks on the output. A built-in subtitle editor lets you correct and time the text before you export, and you can export SRT for YouTube, VTT for the web, or a full plain-text transcript for podcasters and bloggers who want an article-ready version. UrlToSub is aimed at creators, YouTubers, podcasters, and bloggers who need an AI video subtitle generator that keeps their media private and skips sign-up friction; it is free to start with no card needed.
What is UrlToSub used for?
Creators, YouTubers, podcasters, and bloggers generating private, in-browser subtitles and transcripts from their own video and audio files.
