Subtitle generator
Auto Subtitle Generator
An auto subtitle generator turns the speech in a video into timed subtitles without any typing. Upload an MP4 or MOV, choose the language that is spoken, and the AI writes the subtitles and syncs every line to the audio. You correct any word in the editor, pick a look, and export the video with the subtitles built in. It works for English and ten Indian languages, Hindi and Hinglish included.
Start with 3 free minutes. Free exports may include a CapsAI watermark.
Upload Video
For best results, upload a video with clear speech. You can review and edit the captions after generation.

What the captions look like
Interview with two voices
What made you start? — Honestly, boredom.
Speakers are not labelled automatically. Give each answer its own line, or add a name in the text if viewers need it.
English technical term
Export at 1080p, then upload to YouTube.
Product names, numbers and resolutions are where the automatic draft is most often wrong, so they are worth a second look.
Hindi spoken, Hindi subtitles
आज हम तीन आसान तरीके देखेंगे
Choose Hindi and the subtitles come out in Devanagari; choose Hinglish for speech that mixes Hindi and English.
Line too long for a phone
This is the one setting most people never change
Long sentences become two shorter subtitles so each one stays readable on a small screen.

How it works
How it works
Step 1
Upload your video
Add an MP4 or MOV of up to 10 minutes. Subtitles are timed to this exact file, so finish editing the video first.
Step 2
Choose the spoken language
Select the language people speak in the video: English, Hindi, Hinglish, Bengali, Telugu, Marathi, Tamil, Urdu, Gujarati, Kannada or Punjabi.
Step 3
Let the AI write and sync
The automatic subtitle generator transcribes the audio and places every subtitle on the timeline with its start and end time already set.
Step 4
Check names and numbers
Read the draft once. Fix misheard names, figures and slang directly in the text; the timing stays with the words.
Step 5
Style and export
Pick a subtitle style, set the position and size, then export an MP4 with the subtitles burned into the video.
Choose your spoken language

Questions
Is the auto subtitle generator free?
You can start with 3 free minutes, with no card and no subscription. After that, minutes come in one-time packs.
Will my video have a watermark?
Watermark-free export is included with every paid minute pack. Use the free minutes to generate and edit subtitles first, then check the pricing page for what each pack includes.
How accurate are automatic subtitles?
Accuracy depends mostly on the audio. Clear speech close to the microphone needs few corrections; background music, people talking over each other and heavy accents need more. Read the draft once before you export.
Which languages can it subtitle?
English, Hindi, Hinglish, Bengali, Telugu, Marathi, Tamil, Urdu, Gujarati, Kannada and Punjabi. Choose the language that is spoken in the video.
Can it translate subtitles into another language?
No. Subtitles are written in the language that is spoken. Translation is not part of the workflow today.
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.
Can I add subtitles to an audio file or a YouTube link?
No. Upload a video file, MP4 or MOV. Audio-only files and links are not accepted; for a podcast, upload the video version of the episode.
How long can my video be?
Up to 10 minutes per video, and up to 500 MB on the free plan. Split longer recordings into parts and subtitle them one after another.
Can I add subtitles to Instagram Reels and YouTube Shorts?
Yes. Upload the vertical video, generate the subtitles, keep them clear of the app buttons, and export the MP4 to post. Because the subtitles are part of the video, they show even with the sound off.
What if a subtitle is out of sync?
Timing is set from the audio, so lines normally appear as they are spoken. If one is early or late, adjust its start or end time in the editor before export.
Subtitles or captions?
Subtitles show what is said in a video as text on screen. Captions usually also describe other sounds, and for creators the two words often mean the same thing. This page is about generating subtitles from speech. To style them with word-by-word highlights, emoji and animation, see the auto caption generator.
When the automatic draft needs a human check
An automatic subtitle generator is fastest when it does the transcription and timing and a person spends a minute reading the result. Names of people and brands, numbers and prices, and slang are the lines to read twice. Everything else usually needs no change.
