English
vocab decks,
B1–C2.

Sage Ape has 12 curated decks of English vocabulary — six topics, each at two levels. Every card is a real sentence with one word or phrase missing: you guess it, flip the card, and mark it Caught or Missed.

The 6 B1–B2 decks are free. The 6 C1–C2 decks come with Premium ($4.99/month).

B1 (intermediate) and B2 (upper-intermediate) on the CEFR scale: the phrasal verbs, collocations and everyday words you need to follow conversations, news and work emails comfortably.

C1 (advanced) and C2 (proficiency): precise, lower-frequency vocabulary for professional writing, exam preparation and reading nuanced material.
