iPhone · 3 free covers

vibatorial.

Vibatorial writes the caption. Point it at any photo and it returns a headline, a subhead and a full editorial layout — composed on your iPhone in about ten seconds, in whichever of fourteen voices you pick.

Most photo apps hand you a filter and leave the hard part — the words — to you at the moment you least want to write. This one starts there.

What does an AI caption actually sound like?

Like this. Every line below was written by Vibatorial from the photograph beside it. The headline is set in Newsreader, the subhead in its italic, and the cover is drawn by the same composition system that runs in the app — so what you are reading is the product, not a mockup of it.

ELEVATION

THIN AIR

Where shadow cuts the snow at 11,000 feet.

STREET LEVEL

NEON DOWNPOUR

Rain pooling between the signs. The crowd thins to umbrellas.

THE MENU

HAND ROLL

Salmon gloss, rice vinegar still wet on the nori.

Fourteen voices, because one house style is a tell

A caption that sounds machine-written usually sounds that way because everything it writes sounds identical. Vibatorial ships fourteen distinct registers and you choose per cover, so the same photograph can come back dry, warm, or barbed.

Nine more ship alongside these — among them Nerdy, Fit Check, Fashion Roast, Nature Doc, Museum Placard and Auction Lot.

How Vibatorial makes a cover

Three steps, about ten seconds. The writing happens on Anthropic’s Claude models; the typography is composed locally on your iPhone, which is why it is fast and why your photograph never becomes someone’s training data.

Questions

Does it cost anything?

Your first 3 covers are free with no account. After that, Vibatorial Pro is $7.99 a month or $29.99 a year, and the year starts with a 7-day free trial. There is also a one-time $1.99 purchase that just removes the watermark if that is all you want.

Do I need an account?

No. There is no sign-up, no email, and no profile. You open the app and make a cover.

What happens to my photos?

The photo is sent once to generate the caption and is not stored or used to train anything. The layout and typography are composed on your device, and the finished cover never leaves your phone unless you share it.

Can I edit what it writes?

Yes. Every headline and subhead is editable, and you can regenerate, change the voice, or move the type and reframe the photograph afterwards.

What is it actually for?

Instagram and TikTok posts, Stories, and anywhere a photograph needs a line of type over it and you do not want to open a design tool to get one.

Is there an Android version?

Not yet. Vibatorial is an iPhone app; the typography engine is built on Apple's on-device rendering.

You already took the photo.

The only thing standing between it and a post is a line you don’t feel like writing. That is the entire job.
