Features
Captions people actually read
Most viewers scroll with the sound off. Clear, well-timed captions keep them watching.
Fix any word
Misheard a name? Edit the transcript line by line. The timing stays put while you type.
Cut pauses automatically
Long silences are trimmed to a natural gap, so your video feels tight without manual editing.
Remove “um”s and retakes
Filler words disappear, and when you say a line twice, you choose which take to keep.
Jump cuts, highlights & emojis
A subtle zoom at each cut, key words in colour and a few fitting emojis. Every extra is optional.
Three styles, instant preview
Switch between Classic, Highlight and Bold Pop and see the result live before you render.
Safe for Reels, Shorts & TikTok
Captions stay clear of the like buttons and description text those apps draw over your video.
Hindi, Tamil & Malayalam
Proper fonts for Indian scripts, so letters join correctly instead of turning into boxes.
MP4 and SRT
Download the captioned video, plus an SRT subtitle file for YouTube or other editors.

FAQ
Questions, answered
Is it free?
You can start free with 3 videos a month (with a small Pulze watermark). Paid plans start at ₹499 / $9 a month, are prepaid with no auto-debit, and remove the watermark. See the pricing page for details.
What videos work best?
Talking-head clips: one person speaking to the camera, recorded on a phone or webcam. MP4 or MOV, up to 3 minutes and 100 MB.
Which languages are supported?
English works best. Hindi, Tamil and Malayalam are supported with proper fonts, but expect to fix a few more words in the editor for those languages.
What happens to my video?
It never leaves your device. Pulze captions and renders the video right in your browser. Only the audio is sent to an AI speech-to-text service to find the words, and nothing is stored on our servers. Your original file is never changed.
Why does rendering happen on my device?
It keeps your video private and lets Pulze stay free. On a recent laptop, rendering takes roughly as long as the clip itself; older phones can be slower. Keep the tab open until it finishes.
Does it cut pauses or ums?
Yes, if you want it to. In the editor you can cut long pauses, remove filler words like “um” and “uh”, drop retakes you approve, and add a jump-cut zoom. Everything is off by default, and you can preview the result before rendering.
