Word-by-word captions in English and Hinglish, in twenty-two looks worth
posting. Your laptop does the rendering — so the video never leaves your
device, and nothing is capped, queued or squeezed.
Your video is captioned and re-encoded right here in the browser. Only the
sound goes out — about 0.2 MB a minute — so the words can be recognised,
and it isn't kept afterwards.
No two-minute cap
Tools that render on their own servers pay by the minute, which is why they
stop you. Your laptop sends no invoice: a 30-second Reel or a 40-minute
podcast, exported as often as you like.
Built for Hinglish
Devanagari that renders properly, code-mixed sentences that stay readable,
and a list of your own names and brands so they are spelled right every
time instead of guessed at.
How it works
Three steps, about a minute
No account to make, nothing to install, no queue to wait in.
1
Open your video
An MP4, a MOV — or a recording with no picture at all. The sound goes off
to be turned into words; the video stays exactly where it is.
2
Pick a look, fix the words
Twenty-two styles, tried on your own footage. Correct a name, move a word,
drag the captions to where they belong.
3
Download and post
An MP4 with the captions burned in, or an SRT or Final Cut file for the
edit you have already started.
The library
Twenty-two looks. Eleven are free.
Every card below came out of the app itself — the same fonts, the same
renderer, the same pixels you export. Nothing here was drawn by hand for
the sake of a nice screenshot.

and then change anything
Font, size, colour, outline, box, glow, position, animation — or give one
caption in the middle of a video a look entirely its own.
Timing
Every word on its own clock
Captions are cut into phrases that read comfortably, and every word keeps
the moment it was actually spoken. That is what lets a word fill with
colour as you say it, pop as it lands, or type itself onto the screen.
The word worth emphasising is picked for you — or from how loudly and how long you said it.
Wrong word? Click it and type. The timing stays where it was.
Move a word between captions, split one, or nudge everything by a tenth of a second.
The editor
Everything on one screen
Drag, type, done. What you change shows on the video as you change it.
Drag it where it belongs
Move the caption on the video, resize from the corner, and get a warning when it slips under Instagram's own buttons.
A timeline with the sound on it
The waveform and every caption block: drag to move, pull the edges to retime, double-click to retype, split at the playhead.
Safe zones that match the app
Reels, Shorts and TikTok overlays drawn where the real buttons sit, so nothing important hides behind them.
Your own fonts
Add a .ttf or .otf and it stays in your browser — never uploaded, never shared.
One caption, its own look
Give a single line another style, colour or size when it needs to hit harder than the rest.
Undo everything
Every edit, all the way back, and your work is remembered per video if you close the tab.
Sound only
A voice note is a Reel waiting to happen
Open an MP3, an M4A or a WhatsApp voice note and the words are captioned
onto a background of your own: 9:16 for Reels, 1:1 for the feed, 16:9 for
YouTube, in whatever colour suits you. Out comes an MP4 with your recording
intact.
Podcast clips, voiceovers, a thought you had in the car.
Language
हिंदी, Hinglish, and the mix you actually speak
Most caption tools are built for English and treat Hindi as an afterthought.
This one is built here: Devanagari renders properly, code-mixed sentences
stay readable, and the words a recogniser keeps getting wrong are fixed once
and remembered for every video after.
More Indian languages next, in the order you ask for them.
Exports
Finish where you already edit
MP4Captions burned in. 720p free, 1080p on a paid plan, and the sound copied across untouched.
SRT & VTTFor YouTube's subtitle upload, VN, Premiere, or anything else that reads a subtitle file.
Final Cut XMLThe captions as real, editable titles. Paste them onto your edit — the master is encoded once.
TranscriptThe whole thing as plain text, for a description, a blog post or the next script.
Exports never count against a quota. Your device did the work, so there is nothing to meter.
Pricing
Priced for creators here
About a third of the nearest tool, because rendering costs us nothing. We
pay only to turn speech into words, so that is all you pay for.
In a hurry? ₹9 unlocks one export without a watermark, and ₹39 buys a
week of everything with no renewal. Yearly costs ten months. Prices are in
rupees, with GST included wherever it applies.
Paid plans open when we launch. The free tier works today.
Straight answers
Does my video get uploaded anywhere?
No. It is read, captioned and re-encoded inside your browser. The only thing
that leaves your device is the sound, compressed to about 0.2 MB a minute, so a
speech model can turn it into words. We don't store it, and we never train
anything on it.
Why is there no limit on video length?
Because the rendering happens on your machine, not ours. A tool that renders
on its own servers pays for every minute you export, so it has to cap you. We
aren't paying for it, so we don't.
Will it work on my phone?
The editor and the caption files work in any modern browser. Making the MP4
needs the browser to encode video, which Chrome and Edge on a computer do well
and Android Chrome manages for short clips. On an iPhone, take the SRT or Final
Cut file, or come back to a laptop for the video.
How good is it with Hindi and Hinglish?
Good, and getting better. Hindi comes back in Devanagari and the Devanagari
style renders it properly. For Hinglish we pair an Indian speech model with
word-level timings, so the spelling is right and the timing is still exact.
Anything a recogniser keeps mangling — a name, a brand — you fix once and it
stays fixed.
Can I use my own font?
Yes, on a paid plan: add a .ttf or .otf and it is stored in your browser
only. The fonts that come with the app are open-licence ones we are allowed to
pass on, so you can use them commercially.
What happens if I cancel?
You keep everything until the period you paid for ends, and you are not
charged again. Your videos and transcripts were never ours to hold on to.
