Connect with a broader audience through enhanced accessibility
80% of viewers are more likely to finish a video with captions — they enhance clarity, boost retention, and keep audiences engaged. By adding an extra layer of context, captions improve comprehension and help maintain focus, leading to longer watch times and better information retention.
Captions also improve a video's accessibility, reaching viewers who are hard of hearing, absorb written information more easily, or watch in noisy environments. They’re equally as valuable on fast-moving platforms like Instagram and TikTok, where you have just a 1-5 seconds to grab attention. Reach more people — including those watching on mute — with our highly accurate auto-captions, whether used for training materials, product demos, social media, or educational content.

What's different about Kapwing?
Frequently Asked Questions
How do I convert dialogue or narration into captions?
Kapwing's AI-powered video caption generator includes speech recognition that automatically detects spoken voice in an audio or video file. Kapwing then creates an editable transcript for your spoken dialogues that can be modified directly and used as video captions. Lastly, you can either hardcode (e.g., permanently burn) your subtitles into a video or download them as a caption file in SRT, TTV, or TXT formats.
How can I translate captions into another language?
Kapwing's video caption generator can translate to and from over 100 different languages, including Chinese, Spanish, Hindi, and French. Just upload your video and select "Auto subtitles" to generate captions in your preferred language. Then, select the language you'd like to translate your captions to. Kapwing will translate your closed captions automatically and then update your video.
Is the AI Caption Generator free to try?
Yes, the AI Caption Generator for video is free for all Kapwing users to try. A Free Account provides you with 10 free minutes of auto captions per month. When you upgrade to a Pro Account, you get access to 300 minutes of automatic captions every month, plus the ability to create videos up to 120 minutes long and 300 monthly minutes of video translation.
Is there a watermark on exports?
If you are using Kapwing on a Free account then all exports — including from our AI Caption Generator — will contain a watermark. Once you upgrade to a Pro account the watermark will be completely removed from every video you add captions to —and you'll also get 300 monthly minutes of video translation.
Is there a difference between open captions vs closed captions?
Captions improve accessibility for viewers who are hard of hearing or retain info better when reading along. They typically showcase dialogue and background noises, and there are two main types: open captions, which are integrated (or "burned") into the video itself, and closed captions (CC), which can be turned on or off by the viewer.
What is video accessibility?
Video accessibility is the process of creating video content that is accessible to everyone, including individuals with disabilities. The purpose of making video accessible is twofold: it both promotes a more inclusive experience for viewers and helps creators access a larger audience. By bridging the gap for viewers who need accommodations due to hearing or vision loss, you ensure that everyone has equal access a video's information (or entertainment).
An example of an accommodation created for hearing loss is subtitles or captions, since they reproduce spoken content or environmental noises in visible text that viewers can read. On the other hand, choosing high contrast colors for subtitles/captions like blue and orange or black and white can help those with partial loss of vision read text more easily.
What to do if your captions are out of sync
Our AI-powered automation should perfectly sync your captions. However, you are able to manually alter the timing of each caption line by editing the transcript on the left-hand side of the screen. Here, you'll see start and end time columns, allowing you to make exact adjustments to the duration of each line.
Can captions be applied to multiple speakers?
Yes, Kapwing's AI Caption Generator auto-detects multiple speakers, separating them into distinct subtitle sections and enabling you to make unique edits to each one. You can customize the color, speed, fonts, and other visual elements of each individual speaker.
Can I edit and customize captions after they are generated?
Yes, once captions are generated, you can edit the text through the text transcript on the left-hand side of the screen. Simply click on the transcript to manually edit the subtitle text or adjust its duration. To customize the style, use the right-hand panel to choose a font, size, color, background, animation, and transition.
In what formats can I export my captions?
You can export captions in popular formats like SRT, VTT, and TXT, making them easy to use across platforms like YouTube, TikTok, and LinkedIn.
