How It Works

Three steps to understanding any language.

01

Press the Hotkey

Press the global hotkey (default ⌘⌃⇧T) from any app. A precision crosshair cursor appears.

02

Drag to Select

Drag over any text on your screen — in any app, any window, any language.

03

Read the Translation

The translation appears instantly in a floating panel. It keeps updating as the source text changes.

Features

Built for how you actually work.

Drag to Translate

Press the global hotkey from any app. A precision crosshair appears — drag over any text on screen. Language Lupa captures, recognizes, and translates it in seconds.

Live & Continuous

Language Lupa keeps watching your selected region. When the text changes, the translation updates automatically — ideal for game subtitles, movie captions, or streaming foreign content.

Fully On-Device

Screen capture, OCR, and translation all run locally using Apple’s native frameworks. Your text never touches a server. No account required.

Multiple Overlays

Translate several regions at once. Each overlay operates independently with its own language pair — monitor game subtitles and a chat window simultaneously.

Stays Out of Your Way

Translation panels float above your windows without stealing focus. Drag them anywhere. Resize the selection frame. Copy text with one click.

Customizable Hotkeys

Set your own keyboard shortcuts for capture and visibility toggle. Changes apply instantly — no restart required.

Pricing

One app. One price. No subscriptions.
