Caption Generator for Videos
CapsAI turns the speech in your video into timed captions you can edit, then burns them into an MP4 in the style you pick. It is built for people who speak English, Hindi, Hinglish and eight other Indian languages, so a sentence that switches language halfway does not have to be forced into one.
Start with 3 free minutes. Free exports may include a CapsAI watermark.

How it works
How it works
Step 1
Upload an MP4 or MOV
Use the final cut. Captions follow the audio of the file you upload, so trim first if you plan to.
Step 2
Choose the spoken language
Pick one of 11 options: Hinglish, English, Hindi, Bengali, Telugu, Marathi, Tamil, Urdu, Gujarati, Kannada or Punjabi.
Step 3
Review words and timing
Fix names, brand terms and numbers, split long lines, and nudge any caption that appears early or late.
Step 4
Style it and export
Choose fonts, colours, position and animation, or switch on Emoji Sync, then export an MP4 with the captions burned in.

Questions
Is the caption generator free?
You can start with 3 free minutes without paying. More minutes come in one-time packs. Free exports may include a CapsAI watermark; watermark-free export is a paid benefit.
Which languages can it caption?
Hinglish, English, Hindi, Bengali, Telugu, Marathi, Tamil, Urdu, Gujarati, Kannada and Punjabi. Captions come out in the spoken language you select. Translation into another language is not available yet.
Can I download an SRT or VTT file?
The export is an MP4 with the captions burned in. Separate SRT or VTT files are not available from the editor yet; the standalone converters under /tools work on subtitle files you already have.
What if my video mixes two languages?
Choose Hinglish for Hindi-English speech. For other mixes, pick the main spoken language and check the mixed phrases in the editor before you export.
Do burned-in captions help my video rank?
Not directly. Search engines and platforms read your title, description and any caption files, not text drawn into the picture. Burned-in captions help the people watching, especially without sound.
Captions on the video, and captions for the post
Creators use the word caption for two things: the words that appear on the video, and the text typed under the post. This page does the first. CapsAI is building a second mode that drafts the post caption, hook line and hashtags from the same transcript, so both come from what you actually said rather than from a blank prompt.
Why a two-minute review still matters
Speech recognition gives you a first draft. Names, brand terms, numbers and slang are where drafts go wrong, and they are exactly the words viewers notice. A short pass in the editor usually catches them before anything is published.
Caption or subtitle?
In India the two words are used interchangeably. Strictly, captions follow the spoken language and can include sounds for people who cannot hear, while subtitles often translate. CapsAI produces captions in the language spoken in your video.
