Caption-Lagao

Auto captions

Auto caption generator from your video

An auto caption generator reads the speech on a video file and writes the words on screen. Caption-Lagao does that in the browser: drop an MP4, generate word-timed captions, edit anything that looks wrong, then export.

Sample: auto captions on a talking clip

Checking audio…

A preview of word-timed captions on a short clip — then you style and export.

Who this is for

For anyone searching a caption generator from video — talking-heads, tutorials, ads — who wants a free AI pass without a watermark or a sign-in wall.

The problem

Many “AI caption” tools either watermark the export, ask for an account, or write a late paragraph instead of words timed to the voice. Photo caption generators are a different product entirely.

How Caption-Lagao treats the speech

Caption-Lagao captions a video you already have. Timing is per word so karaoke and highlighter styles work. Output can be English, Roman Urdu, or mixed speech. The export is the styled MP4 you previewed.

Your file

The video stays on this device. Audio is sent only to generate the transcript. No account, no public gallery.

How it works

  1. 1

    Upload the video

    MP4, MOV, WEBM, or another supported clip up to 200 MB. The picture never leaves this device as a public upload.

  2. 2

    Generate captions

    Speech is transcribed with word timestamps. Choose Roman Urdu if the speech is Urdu; keep English as English.

  3. 3

    Edit on mute

    Fix leftover words, split long lines, place the block above platform UI.

  4. 4

    Export

    Download the burned-in MP4. Add SRT if you also need a subtitle file.

This page is the generic auto-caption tool: speech on a file → captions on that file. It is not a photo-quote writer, a birthday-caption pack, or a topic-to-hashtag box.

Read the draft once on mute. Names, numbers, and English brand words are the usual fixes. Then pick a style and export.

Download a burned-in MP4 for mute autoplay, plus optional SRT, VTT, ASS, or TXT. No Caption-Lagao watermark.

Questions

What is an auto caption generator?

It transcribes speech on a video and writes those words as on-screen captions. Caption-Lagao does this from a file you upload — not from a photo or a caption prompt.

Is this AI caption generator free without a watermark?

Yes. You can generate and export without an account. The MP4 matches the preview, without a Caption-Lagao mark.

Does it work from a video, not a photo?

Yes. Caption-Lagao captions speech on video. It does not write Instagram photo quotes, birthday captions, or bio copy.
