Where the name comes from

In Goiás, Brazil, uai is what people say when something doesn't make sense.

In English, it sounds like why. Both ask the same thing: what is this?

The app answers.

uai? · pocket translator
Where it came from

Born from an everyday detour.

Reading in another language, seeing prices in another currency, replying to a seller abroad. Every time the same path: copy, open another window, paste, go back. On Windows, nothing translated on its own when you select and pause. What existed needed a browser extension, one more shortcut or a new computer.

Summarize came from a friend at UEG, in Brazil, who reads scientific papers in English every week. The rest came from the people who tested it.

FAQ

Before you ask.

Is it free?

Yes. The beta is free, by invite. After it, the Free plan stays free forever and Pro is optional. See pricing.

What happens to my text?

The app only reads what you select, and only after you agree. Translation goes straight from your computer to Google Translate, without passing through our server. The AI only gets the text when you click, and the text isn't stored. Password fields are never read. Details in the privacy policy.

Why does Windows warn me when installing?

The beta installer doesn't have a paid certificate yet, so Windows doesn't know the author. Click More info and then Run anyway.

What about the Mac?

It works, in preview. The app isn't signed by Apple yet, so the first launch takes one extra step. The steps are on the download page.

When will my invite arrive?

Every request is approved by hand, with no set date. When yours is ready, a code and the download link arrive by e-mail. Check your spam too.

What are AI credits?

It's how uai? measures AI use. Each request spends credits according to the size of the text and the answer: explaining an acronym spends a few, summarizing a long article spends more. Free gets 1,000 credits a month and Pro, 10,000. In the app, under Account, you see how much of the month you've used.

When does Pro come out?

Subscriptions open after the beta. Testers get all of Pro for free now.

How many computers can I use it on?

Up to 3, with the same account.

Does it work offline?

Partly. Translation and AI need the internet. Clipboard history works offline.
