An example of editable, word-by-word captions. Choose your own style in the editor.
Your speech. Your words. Your style.
AI caption generation starts with the audio in your video. Lumiox transcribes speech and gives each word a timestamp. Review the transcript, correct names or mixed-language phrases, then choose how those words appear on screen. These are captions for spoken video, rather than descriptions or hashtags for a social post.
How it works
- 1
Choose a video and language
Open the editor, pick an MP4, MOV or WebM video and select the spoken language. Only the audio is sent for transcription; your footage stays on your device.
- 2
Check the AI transcript
Listen back while reading the captions. Fix a name, spelling or phrase and adjust word timing where needed before styling the result.
- 3
Make the captions yours
Choose a caption template, change the font and colors, and preview the timing. Export an MP4 with the captions visible in the video.
Let spoken words set the pace
Word-level timing helps highlights follow speech. Keep caption groups short enough to read and check fast sections at normal playback speed.
Keep the mix in Hinglish
Hindi and English often share a sentence. Review names and borrowed words in context, and choose native script or Roman text to suit the people watching.
Review before you export
AI can mishear quiet speech, background noise and unfamiliar names. A quick read-through gives you a chance to correct the transcript before it becomes part of the finished video.
Find your language and your look
Explore Hindi captions, Hinglish captions, Tamil captions, or browse all supported caption languages. Choose from animated caption templates and check current plans and export options before starting a longer project.
Questions before you start
What does an AI caption generator do?
It transcribes spoken audio and places the resulting words on a video with timestamps. In Lumiox you can edit those words, adjust timing and apply animated caption styles.
Can I generate auto captions for free?
Yes. Lumiox has a free plan with transcription limits and watermarked MP4 exports. SRT and VTT subtitle downloads are included on paid plans. See pricing for current allowances.
Does it write Instagram post captions or hashtags?
No. This tool creates on-screen captions from spoken video. It does not generate post descriptions or hashtags.
Can I correct the captions after generation?
Yes. Edit the transcript and word timing, then preview your changes. Review the final captions before exporting, especially names, numbers and mixed-language speech.
