Monmot saves a word in the sentence you met it in, explains it in the language you are reading, and brings it back before it fades.
Free to start, no account needed.
Monmot opens on the page you are reading. Nothing to copy, no tab to switch to.

Drag across a word or a phrase, then click the Monmot chip. The card opens beside it.
The word goes in with its sentence, the page and the date.
Saved words stay marked on every page you open after.
