How fast can I caption a clip before posting?

Most short clips are transcribed, synced, and styled in under a minute. Upload, skim the captions for any fixes, export—the whole detour from "edited" to "posted" takes a couple of minutes.

Does the AI handle slang, brand names, and fast talking?

Yes. The transcription model is trained on real conversational speech, so casual phrasing and quick delivery come through accurately. Unusual brand or product names occasionally need a one-click correction in the editor.

Are captions burned into the video or a separate file?

Burned in by default, which means they display identically on TikTok, Reels, Shorts, LinkedIn, and anywhere else—no relying on each platform's own caption rendering.

Will captions get covered by TikTok or Reels buttons?

No. Position captions inside the safe zone so usernames, like buttons, and audio labels never overlap your text. You preview exact placement before exporting.

Can I save a caption style and reuse it on every clip?

Yes. Set your font, colors, size, position, and animation once, then apply that style to every future upload so your content stays visually consistent.

What's the difference between captions and subtitles?

In everyday use they're interchangeable. Technically, captions transcribe the audio for viewers who can't hear it, while subtitles translate it. Eliro generates both from the same upload.

Do exported videos have a watermark?

No. Your captioned video exports clean, with nothing added except the captions you styled.

Can I try the caption generator for free?

Yes. The free tier lets you caption your first clips end to end, so you can judge the accuracy and styles on your own footage before paying anything.

AI Caption Generator

Captioning is the chore standing between your finished clip and the post button. Eliro's AI caption generator transcribes your audio, syncs every word to the waveform, and burns styled captions straight into the video—so a clip that used to take twenty minutes of typing is feed-ready before your coffee cools. Slang, brand names, fast talkers: it keeps up.

Captions That Keep Up with a Daily Posting Schedule

Built for creators who caption every single clip before it goes out

Word-Level Sync, Zero Typing

The AI transcribes your audio and snaps each caption to the exact moment it's spoken. No retyping, no dragging text boxes along a timeline.

Handles Real Speech

Slang, filler-free fast talk, product names, accents—captions come out right the first time, and anything off is a two-second fix in the editor.

Styled for the Feed

Pick a caption look once—font, color, highlight animation—and reuse it on every clip so your posts are instantly recognizable mid-scroll.

Safe-Zone Positioning

Place captions where TikTok buttons, Reels usernames, and Shorts UI won't cover them. What you preview is exactly what viewers see.

How Caption Generation Works

Step 1

Drop In Your Clip

Upload the video you're about to post—MP4, MOV, AVI, or a pasted URL. The AI starts listening immediately.

Step 2

Captions Appear, Already Synced

Every spoken word becomes an on-screen caption, timed to the audio. Skim the transcript and fix any word with one click.

Step 3

Style It and Post

Apply your saved caption style, export with captions burned in, and publish to any platform without re-uploading caption files.

Get More From Every Captioned Clip

Caption Styles Borrowed from the For You Page

The bold, word-by-word caption looks dominating TikTok and Shorts right now are built in as presets. Apply one, tweak the colors to your brand, and your captions stop looking like an afterthought.

One Clip, Captioned in 50+ Languages

Posting the same clip to audiences in different countries? Translate your captions instead of re-recording. The AI keeps context intact so jokes and product names survive the trip.

Fix Mistakes Without Starting Over

When the AI mishears a niche term, you edit the word—not the whole caption track. Timing stays locked while you correct spelling, add speaker labels, or split a line that runs long.

Finish the Whole Post in One Tab

Captions get clips watched—these tools get them finished. Polish the same upload before it leaves Eliro.

AI B-Roll Generation

Cover jump cuts in your captioned talking-head clips with AI-matched B-roll instead of hunting stock sites.

Auto Zoom & Pan

Add punch-ins on the lines your captions emphasize, so the visual energy matches the text.

Sound Effects

Drop a pop or whoosh on caption reveals and transitions to make key words land harder.

Publish & Schedule

Send the captioned clip to TikTok, Reels, and Shorts from the same screen you captioned it on.

AI Video Editor

Trim, cut, and rearrange the clip on a full timeline without ever exporting to another app.
