Auto Caption Generator

Captions that land word by word, styled to match your channel, burned into every clip.

No credit card required

Features

Word-level timing

Words highlight as they are spoken rather than appearing a line at a time. That is what makes short-form captions readable at scroll speed instead of just present.

Styles worth choosing between

Karaoke highlight, pop, and bounce, with emoji support. Pick per project or save one as the default so every clip comes out consistent.

Burned in, no sidecar files

Captions are rendered into the video itself, so they display the same on TikTok, Reels, and Shorts with nothing to upload alongside.

Brand kits and translation

Save fonts, colors, and a logo as a brand kit so captions match your channel. On Pro and up, captions translate into 31 languages, with AI dubbing if you want the audio to follow.

How It Works

Submit a video

Paste a public URL or let a monitored channel feed it in. Captioning is part of every clip, not a separate step you enable.

Speech is transcribed with word-level timing

Each word gets its own timestamp, which is what allows the highlight to track the voice instead of drifting behind it.

Captions render into the clip

Your chosen style is burned in and the clip is ready to post. Text is editable on web if a name or acronym came out wrong.

Frequently Asked Questions

How accurate are AutoClip's captions?

High on clear speech, and reliable enough that most clips need no edit at all. Where it slips is predictable: heavy background music, thick regional accents, crosstalk between speakers, and proper nouns it has never seen. Caption text is editable on web, so fixing a misheard name takes a few seconds rather than a re-render.

Can I customize the caption style?

Yes — karaoke highlight, pop, and bounce out of the box, with control over font, size, color, and position. Pro adds a brand kit with 2 custom fonts; Scale allows unlimited brand kits, which matters if you run captions for several channels.

Are captions added automatically to every clip?

Yes, by default, on every clip. You do not toggle anything on. If you want a clean version without captions for a particular platform, you can turn them off per project.

Why do short-form videos need captions?

A large share of short-form gets watched with the sound off — on public transport, in bed, at a desk. A clip that only works with audio loses those viewers in the first second, before they have any reason to reach for the volume. Captions also give people a reason to stay when the audio is quiet or the accent is unfamiliar.

Are captions burned into the video or a separate file?

Burned in. Short-form platforms handle sidecar subtitle files inconsistently and some ignore them entirely, so rendering the text into the frame is the only way to be sure it shows up everywhere the clip lands.

Does the auto caption generator work for non-English content?

Yes. Transcription handles major languages, with English the most accurate. On Pro and above, captions translate into 31 languages and AI dubbing can carry the audio over too, which is the usual way people take one clip into a second market.
