The RegiAI AI subtitle generator listens to the speech in your video and writes a timed .srt subtitle file you can load into YouTube, Premiere Pro, CapCut, DaVinci Resolve or a video player. Upload a video of up to 15 minutes, let it detect the spoken language or pick it yourself, and switch on translation if you want English subtitles for speech in another language.
It costs $0.10 per video, and signed-in users get one free generation a day on tools at this price. For a YouTube link instead of a file, the YouTube Transcript Generator is faster. For plain text without timestamps, use AI Speech to Text.

What you get: a standard SRT subtitle file
SRT is the most widely supported subtitle format. Each line has a number, a start and end timestamp, and the text spoken in that moment. The subtitle generator returns:
- A downloadable .srt file with timestamps that line up with your video.
- The same text on screen, so you can copy it, fix a name or a word, and paste it into a doc or description.
Because SRT is plain text, you can open it in any text editor to correct spelling or split long lines before importing. YouTube, Vimeo, Facebook, LinkedIn, Premiere Pro, Final Cut Pro, DaVinci Resolve, CapCut and VLC all accept it.
Need subtitles inside the video picture itself (burned-in captions)? Import the SRT into your editor and style it there. If you want a short with captions made for you from scratch, AI Script to Video creates the video, the voice and the word-by-word captions together.
Because the file is timed to your upload, keep the video unchanged after generating subtitles. If you trim the start of the video later, shift the subtitle timing in your editor so the lines still appear at the right moment.
Languages, detection and translation
The speech model recognizes about 100 languages. The language menu lists the most common ones, including English, Spanish, French, German, Italian, Portuguese, Russian, Turkish, Arabic, Hindi, Japanese, Korean, Chinese and Azerbaijani, and Detect automatically handles the rest.
- Pick the language when you know it. It avoids detection mistakes on videos that start with music or silence.
- Translate to English produces English subtitles whatever language is spoken. It is useful for sharing foreign-language clips with an English audience.
- For dubbing the voice itself into another language, use the AI Audio Translator.
Accuracy is highest with clear speech and little background music. If your video has loud music, separate the voice first with the AI Vocal Remover.
Subtitles also help people find your videos. Platforms can read the text of uploaded captions, and viewers scrolling with the sound off are more likely to stop for a clip they can follow. For a quick transcript to turn into a blog post or notes, copy the text from the page after it is generated.
Price and the daily free generation
Each video costs $0.10, whether it is 30 seconds or 15 minutes long. Signed-in users get one free generation per day on any AI tool priced at $0.10 or less, including this one. It does not stack or roll over. After that, it is pay per use from your credit balance, with no subscription.
If a transcription fails, the charge is refunded to your balance automatically (or your free generation is given back). Results are saved in My creations for 30 days.
Video files must be under 50 MB. For a long video that is larger, export a lower resolution copy first; the picture quality does not affect the subtitles.
Compared with typing captions by hand, which can take several times the length of the video, an AI subtitle generator gets you a complete first draft in a minute. Budget a few minutes to read it through and fix names and specialist terms, and you have captions ready for YouTube or your editor.
Other subtitle tools often charge per minute or require a monthly plan. Here the price is per video, so a long lecture costs the same as a short clip.
AI Subtitle Generator FAQ

How does the AI subtitle generator work?
It uses a speech recognition model to transcribe the audio of your video with timestamps, then formats the result as an SRT subtitle file.
Is the subtitle generator free?
Each video costs $0.10, and signed-in users get one free generation a day on tools priced at $0.10 or less, so your first video each day is free. It does not stack or roll over.
What file do I get?
A standard .srt subtitle file with timestamps, plus the text on screen to copy.
How long can my video be?
Up to 15 minutes, as an MP4 or MOV under 50 MB.
Which languages are supported?
About 100 spoken languages. Common ones are in the menu, and automatic detection covers the rest.
Can it translate subtitles?
Yes, into English. Turn on "Translate to English" and the SRT will be in English whatever language is spoken.
How do I add the SRT to YouTube?
In YouTube Studio, open the video, go to Subtitles, choose Add language, then Upload file and select "With timing". Pick the .srt file.
Can I get burned-in captions?
This tool gives you a subtitle file. Import it into CapCut, Premiere Pro or another editor to burn it into the video with your own style.
How accurate are the subtitles?
Very good for clear speech. Names, brand terms and heavy accents may need a quick fix, which is easy because SRT is plain text.
Can I get subtitles from a YouTube link?
Use the YouTube Transcript Generator for links. This tool works with video files you upload.
What if my file is larger than 50 MB?
Export or compress a lower resolution copy. Subtitles only depend on the audio, so a small file works just as well.
How long does it take?
Usually under a minute, a bit longer for videos close to 15 minutes.
Can I edit the subtitles?
Yes. SRT is plain text, so open it in any text editor or subtitle editor, fix words or timing, and save. Most video editors also let you edit imported captions.
Does it work with audio-only files?
This tool takes video files. For MP3, WAV and other audio, use AI Speech to Text.
Is there an API?
Yes, subtitle generation is available through the RegiAI API at the same price. See the API docs.
