Use case
A Mac user reading an English page, document or email hits an unknown word and needs its meaning without leaving the current screen.
The built-in macOS dictionary, browser selection-translation extensions, standalone translation apps, or copying into a translation website.
The current path means selecting the word, copying, switching to a translation site or dictionary app, pasting and switching back, which breaks reading flow; the candidate material offers no direct evidence of user complaints or workarounds.
xOcto's call
Problem identified, demand strength unclear
The trend is that word lookup is being compressed from a standalone app into a single system-level keypress. A wedge would be non-native English workers in cross-border trade, study or overseas support, binding instant definitions to a glossary of industry terms instead of shipping another generic translator; no public pricing information exists yet.
Reason to use it
Why users would choose it
Inference: versus copy-pasting into a translation site, holding a key returns the definition in place, removing the app-switch and paste step, so non-native readers who work in English on a Mac may pick it up; however the material does not say what it adds over the built-in dictionary or browser extensions, and there is no retention or repeat-use evidence.
Where the easy answer breaks down
The tension worth following
An English validation note will follow from the public evidence.
