The deck
The shared frequency deck the bot teaches from. European Portuguese from A1 (survival first, Madeira vocabulary included) and English from B1–B2. Every card has native-quality audio.
Search anything, not just what the deck teaches: 100,000+ further headwords sit behind it, and words neither knows are looked up live. Lexicon from English Wiktionary (CC BY-SA 4.0), ranked by an OpenSubtitles frequency list (CC BY-SA 4.0).
