Win the Viewers Who Watch on Mute

Most apps play videos with the sound off, so a video without captions is silent when someone first sees it. That is the exact moment they choose to keep watching or scroll away. Captions give them something to read straight away, even in a noisy place.

Caption, Edit and Publish in One Place

Captions are only the first step. On the same video you can also remove filler words, cut silences, add B-roll, zoom in on key moments and add music, then post it or schedule it. It is all in one app, so you never upload your video twice.

AI Caption Generator FAQs

Do captioned videos export with a watermark?
No watermark, on any plan. Free accounts export watermark-free videos at full quality.
What caption styles can I choose from?
You get more than 20 to pick from. We rebuilt the caption looks top creators use, so a single click puts that style on your video.
Can I change the font, color and position myself?
Absolutely. Font, color, stroke, shadow, position and scale are all yours to adjust, and once you save a look it applies to every new video you make.
What if the AI gets a word wrong?
Just click the word and retype it. Captions work like a text document, so the timing stays correct while you fix the spelling.
How long does captioning take?
Usually just seconds for a short-form clip. You can pick your caption style while you wait, then download it.
Which languages can it caption?
More than 99, including English, Spanish, Hindi, Japanese, Arabic, Portuguese and Mandarin. Your captions come back in the same language you spoke, with the same 99% accuracy.
What video files can I upload?
MP4, MOV, WEBM and M4V are all supported. Drag your file in and captioning starts on its own.
Will the captions work on TikTok, Reels and Shorts?
Yes. Your captions are inside the video itself, so they look exactly the same everywhere you post. You can publish to TikTok, Instagram, YouTube and Facebook directly from Eliro.
Are captions and subtitles the same thing?
For social video, yes — people use both words for text on screen. Eliro puts them inside your video either way.
Is there a free plan?
Yes, and it comes with generous free usage, unlimited downloads and no watermark. Paid plans give you more credits, and they work across every tool in Eliro.
