Swiftin

In production

An AI translator right inside the browser: pages, subtitles and documents.

Where this started

The language barrier slows down reading and communication across the web, and ordinary translators lose tone and context.

Who we built it for

Anyone who reads, watches or writes in a language that is not their own, all day, in a browser.

What fought back

  1. Translating a page without breaking it

    A page is not a document. Replacing text inside a live application has to survive the application rewriting that text a second later, and every site does it differently.

  2. Four surfaces, one product

    Pages, selected text, subtitles and whatever you type in any field are four different problems that have to feel like one feature and share one quota.

  3. Money that must not arrive twice

    Paid plans mean webhooks, and webhooks are delivered more than once. Every one of them has to be safe to replay, or a customer is charged or upgraded twice.

What we actually built

One extension that translates web pages, selected text, whatever you type in any field, video subtitles and whole documents, with AI voice on top.

What came of it

4000+ users and growing, live in the Chrome Web Store, with a free plan and paid subscriptions.
