Use tool ↗About WordFlippin
WordFlippin generates vocabulary flashcards on demand, complete with AI-written definitions and memory mnemonics, then schedules reviews using spaced repetition so words stick. Cards render as a flip animation and cover both single words and idioms across nine languages. The free plan allows 50 new words and 20 idioms per month; the $5 monthly Pro plan removes that cap, adds AI-generated practice exercises, lets you pull vocabulary straight out of pasted articles, and exports your deck to PDF. It's built by a small team called Amic Labs.
