No account needed. Your dictionaries stay on your computer.

Keep the three-finger tap you use for the built-in Look Up, or set a keyboard shortcut. It works in every app, including the ones that never let you select text.
Accessibility lets it read the word under your pointer. Screen Recording lets it read games, images and video. Nothing leaves your Mac until you ask for an AI explanation.
Import a folder of MDict dictionaries once. Every word you look up can be saved with its sentence and reviewed later on your Mac, in the browser or on your phone.
Free, no sign-up
macOS or Windows, under 20 MB, no account needed.
On a Mac, allow Accessibility so it can read the word under your pointer, and Screen Recording for text in games and images. Windows asks for nothing.
Three-finger tap on a Mac, or press your shortcut on Windows. The meaning appears next to the word.
I'm a Mac user, and the trackpad gesture alone made me download it. Lookups are fast, and it combines the strengths of dictionaries and AI.

I used to chain two apps together, one for grabbing words off the screen and GoldenDict-ng for the dictionaries. AALookup does all of that on its own, and the UI is done really well.
macOS 13 or later, on Apple silicon and Intel. The download is 17 MB for Apple silicon and 18 MB for Intel.
It can. Hand the three-finger tap to AALookup in its settings, or keep both and give AALookup a keyboard shortcut.
Only to read text that can't be selected, such as games, scanned PDFs and video. Ordinary text is read through Accessibility, so you can skip Screen Recording if you never need the rest.
