What is a caption maker?
A caption maker turns the speech in a video into on-screen captions. Some are phone apps; Kenerate's runs in the browser, so there's nothing to install. Upload a clip up to 4 minutes, pick one of 10 caption styles and a position, and download one MP4 with the captions burned in, ready for any platform.

- Fusion. Short bursts of words, timed to the speech.
- Simple. Clean white text with a soft shadow.
- Glide Pop. The spoken word in yellow script.

Tips
Captions people stop for
Habits that make a caption maker's output work harder.
Lead with your strongest sentence: the first caption is the hook.
Use one look for a whole series so the posts feel like a set.
Use Rizz or Glide Pop when the speaker is selling an idea.
Use Plain or Lowkey when the visuals carry the story.
Keep music low: the caption maker writes only what it can hear.
Record in a quiet room; echo costs more accuracy than an accent does.
Example uses
How creators use Caption maker
Illustrative examples of typical workflows, not customer reviews.

Office team
A comms team can caption a CEO's short update on a locked-down work laptop, with nothing to install.

Street musician
A busker can caption a short spoken intro from a phone browser between sets and post it straight away.

Estate agent
An estate agent can caption a walkthrough intro in Plain so the words never compete with the rooms.
FAQ
Caption Maker — questions
Is there a caption maker that doesn't need an app?
Yes. Kenerate's caption maker runs in the browser on a computer or a phone, so there is nothing to download: sign in, upload the clip and download it captioned. Phone apps such as Captions, or Instagram's Captions sticker, need their app installed. A browser tool is also handy on shared or work computers where you can't install software.
Link to this answerDo I need a captions app or a website?
It depends on where you edit. If you shoot and post from your phone and want to change words by hand, a captions app with an editor fits. If your clips are already finished and you just want styled captions burned in, a browser caption maker is quicker: Kenerate takes the file, captions it and returns one MP4.
Link to this answerCan I use the caption maker on my phone?
Yes, in the phone's browser. Open Kenerate, sign in, upload a clip from your camera roll and pick a style; the result downloads as an MP4 you can post straight from the phone. Keep clips under 4 minutes and 100 MB. For the clearest text on a small screen, choose 1080p HD and a Mid or Max shadow.
Link to this answerCan the caption maker add emojis or my brand font?
No. It offers 10 fixed caption styles, from Simple to Vegas, with position and text-shadow settings, but no custom fonts, colours, emojis or logos. If your brand needs an exact font, caption the video in an editor with brand kits. For most social posts, using one built-in style across a series reads as a consistent look too.
Link to this answerDoes the caption maker add a watermark?
No. The captioned MP4 has no watermark, and no subscription is required: you pay per clip with credits, priced by length in tiers up to 4 minutes, and new accounts get starter credits to try it. If a run fails, the credits are refunded automatically, so a bad upload doesn't cost you anything.
Link to this answerWhich languages can the caption maker caption?
It captions speech in English (US), English (India), Spanish, French, German, Japanese, Chinese, Italian, Portuguese and Russian, with Auto-detect as the default. The captions match the spoken language and there's no translation step, so a French speaker gets French captions. Pin the language by hand when a clip mixes languages or the accent is strong.

Browser caption maker or captions app?
On this page
What people mean by a captions app
Most people searching for a captions app want something on their phone that writes captions from speech. Captions, the app now developed by Mirage, runs on iOS, Android and the web and adds editing, dubbing and script tools on top [2]. Social apps have their own: Instagram's Captions sticker transcribes Reels in the mobile app [3].
When a browser beats an app
A browser caption maker skips the install, which matters more often than you'd think.
- Work laptops where you can't install software.
- Clips edited on a computer rather than a phone.
- Several people sharing one account on different devices.
- Phones that are short on storage space.
- One-off captioning jobs that don't justify a subscription.
When an app is the better choice
If you want to fix individual words, re-time lines, add emojis or design your own caption template, a full captions app or editor does more [1]. Kenerate's caption maker is deliberately narrower: it takes a finished clip and gives back a captioned one in a few minutes, with 10 ready-made looks instead of a design canvas.
Captions that survive reposting
Because the captions are part of the image, they travel with the file: reposted, forwarded or embedded, the video still shows them. That's the main advantage over captions that live inside one app's player. The cost is that they can't be removed later, so keep your uncaptioned original as well.
Caption maker online
A caption maker you use in a web page. Kenerate's works in desktop and phone browsers and returns an MP4, so nothing is installed and nothing stays on your device but the file.
Video caption maker
A caption maker for moving pictures rather than photo captions or post text. It listens to the speech, so the clip needs a clear voice; music-only videos have nothing to caption.
Captions app
Usually a phone app with a caption editor. Choose one if you edit on your phone and fix words by hand; choose a browser caption maker if your clip is finished and you want it captioned quickly.
