Linguin is an AI translator that lives where you actually read and write โ€” your Mac menu bar, your iPhone, and your Chrome browser. It runs on Google Gemini, so translations preserve context, tone, idioms and formatting instead of word-for-word output.

The product covers 100+ languages and ships across five surfaces:

  • macOS app โ€” system-wide shortcut, menu-bar popover, instant text translation while you work.
  • iPhone & iPad app โ€” voice input, conversation mode, push-notification reminders.
  • Chrome extension โ€” sidebar translator, one-click full-page translation.
  • Safari extension โ€” same in-page experience for Mac/iOS Safari.
  • Web โ€” linguin.app covers 15 locales with a translation playground.

Core capabilities:

  • Smart language detection โ€” no need to pick a source language.
  • Voice input โ€” speak instead of type, on iPhone and Mac.
  • Page translation โ€” translate a full URL or a selection in one click.
  • Sidebar translator โ€” keep a panel open while you browse foreign-language sites.
  • Cross-device โ€” start on Mac, continue on iPhone.
  • Privacy โ€” translations are not used for training.

Pricing is freemium and minimal. Anonymous users get 3 free translations per day. A free Linguin account (Google or Apple sign-in) unlocks unlimited translation on every platform. There is no paid tier; everything billable on DeepL Pro, iTranslate Pro or Mate Translate Pro is free here.

Built by Supafast, an indie AI software studio. macOS and iOS apps are native Swift / SwiftUI; the website is Astro 5 on Vercel; the Chrome extension is Manifest V3.

Best fit for bilingual professionals, students, expats, customer-support teams, web researchers, and anyone who currently bounces between Google Translate, DeepL and a clipboard.

  • Building an AI translator that lives everywhere on macOS, iOS and Chrome
    Most translation tools make you leave what you're doing: copy text, switch to a tab or app, paste, read, copy back. I wanted translation to sit inside whatever I was already using. That turned into Linguin, an AI translator with a native Mac app, an iPhone app, and a Chrome extension. Here's how I think about building the "same" product across three very different surfaces. - Source: dev.to / 14 days ago
