Auto Captions Generator

How This Tool Works

Upload any video or audio file. It transmits it to a voice recognition engine, which captures the utterances with timestamps, then prepares them for subsequent classifications as caption lines. You can save the outcome in SRT or VTT formats for subsequent insertion into your video editor, or as a raw transcript.

Accuracy depends on audio clarity — clean, well-recorded speech transcribes best. Heavy background music or multiple overlapping speakers may need manual touch-ups after generation.

Why Add Captions To Your Videos

A large share of video views on social platforms happen with the sound off — people are scrolling on the bus, sitting in a meeting, or just don't want to disturb someone nearby. If your video relies entirely on audio to make its point, that's a lot of potential viewers who scroll past before your message ever lands. Captions turn a sound-off viewer into an engaged one.

Captions also make your content more accessible to Deaf and hard-of-hearing viewers, and to anyone watching in a second language who follows spoken English more easily when they can read along. On top of that, captions give search engines actual text to index — a video with an accurate transcript has a better chance of surfacing in search results than one that's just a silent block of pixels to a crawler.

None of this requires hiring someone to type out your video line by line. A rough transcript that you clean up in a few minutes gets you most of the benefit, and that's exactly what this tool is built for.

You can quickly generate captions for YouTube Videos, Instagram Reels, TikTok Videos, Podcasts, Online Courses, Interviews, Webinars, and Business Presentations with optional inline editing whenever needed.

Accessibility and Engagement: Captions significantly boost both viewer accessibility and engagement.

Our tool supports a wide variety of video and audio formats, including MP4, MOV, WebM, MP3, WAV, and M4A. Once you upload your media file, our speech recognition engine transcribes the dialogue and provides you with precise, timed caption lines. You can edit every caption line individually right inside the browser to correct unique names, technical jargon, or punctuation.

You can export your completed subtitles in industry-standard formats: SRT, WebVTT, or plain TXT. SRT files are compatible with popular video editors like Adobe Premiere Pro, DaVinci Resolve, Final Cut Pro, CapCut, and Filmora. WebVTT format is ideal for HTML5 web players, and TXT provides a clean, searchable transcript of your entire recording.
