Definition
What is an auto caption generator?
An auto caption generator turns speech into timed on-screen captions you can style and keep on the finished clip. The point is mute-friendly video — not a plain transcript.
- · Captions appear automatically from speech
- · Styles that still read when sound is off
- · Export a clip ready to post the same day
Mute feeds
Auto captions that survive the mute button
Most people watch without sound first. Platform defaults are hard to brand. This auto caption generator puts clear, timed text on screen — in a look you choose — so the hook still lands silent.
- · Readable word timing on short clips
- · Bold presets built for feeds
- · Export you control before you post
Fast path
From drop to auto captions in one session
Skip the multi-app hop. Drop a clip, get captions, preview styles on your footage, and export before the idea cools.

Look
Automatic does not have to mean plain
Karaoke, word-highlight, and emoji styles keep auto captions feeling intentional next to the clips you already scroll.
Feeds
Vertical-ready captions for every feed
After captions generate, set 9:16 or other ratios so text sits correctly for TikTok, Reels, and Shorts — then export without rebuilding the project.
- · 9:16 for vertical posts
- · Keep styles when you resize
- · One caption pass, multiple cuts

How is an auto caption generator different from platform captions? +
Platform defaults are hard to brand. Here you style, time, and keep captions on the file you upload — so the look travels with the video.
Can I fix auto captions if a word is wrong? +
Yes — edit text and timing in the studio before you export.
Do auto captions work for vertical video? +
Yes. After generation, set 9:16 or other ratios. Or start from the TikTok caption generator or Reels subtitles pages for a vertical default.
How is this different from an AI subtitle generator? +
This page is built for mute-first speed on short clips. If you need deeper polish and “not just a transcript” framing, open the AI subtitle generator.
Can I download SRT from auto captions? +
Yes — after captions exist, download .srt / .vtt / .txt from the export menu, or use the SRT generator.
How fast can I finish a captioned clip? +
Most short clips go from drop to styled export in one session — built for same-day posting, not a multi-day edit.
Where do I see plans and upgrades? +
