Why Choose This Auto Caption Generator

Captions are automatically matched to the audio, ensuring each line appears and disappears in sync with the speaker, not just as a block of text.
Multiple Export Formats
Export your finished captions in the exact format you need—SRT for YouTube or TXT for a simple transcript—without conversion hassles.
Handles Any Length
Process anything from a 30-second social clip to a multi-hour webinar or interview series. AI auto caption keeps timing precise, text clear, and speed consistent across every video.

What Our Users Say About AI Captioning

We create weekly video summaries for our leadership team from hour-long strategy meetings. Generating accurate, time-synced captions for such long recordings used to be a bottleneck. Now, we simply upload the file. The captions are ready in minutes, with a level of accuracy that allows us to publish or archive the videos without lengthy manual reviews, saving our department over half a day of work each week.

Jules CarterHead of Learning & Development

I produce weekly explainer videos for my YouTube channel. Before, cleaning up auto-captions was a chore—the AI would break sentences awkwardly. RecCloud’s tool gets the cadence right, so my subtitles actually read like natural speech. It saves me about an hour of editing per video.

For our agency, speed and client-ready quality are non-negotiable. We use this for everything from 30-second ads to 20-minute case studies. The accuracy on the first pass is consistently high, which means my team spends less time fixing errors and more time on strategic edits. It’s become our go-to for captioning.

Marcus ThorneSocial Media Agency Director

As a non-native English speaker doing product reviews, clarity is everything. I use the auto caption generator to create a precise transcript first. Then, I use it to check my pronunciation and pacing. Seeing the words helps me refine my delivery for a global audience. It’s more than a subtitle tool—it’s a confidence check.
