Works with the apps you already use every day.

How it works
Three steps. The whole loop in under a minute.
Capture once. Review on autopilot. Use the words in real life. FlexiLingo is built around the content you already consume — not another textbook to slog through.
Capture
Click any word in a YouTube subtitle, in a podcast transcript, on a webpage, or in a photo from your phone. FlexiLingo grabs the translation, the sentence context, and the difficulty level (CEFR A1–C2).

Saved words land in your deck and surface again at the perfect interval. Pick the spaced-repetition algorithm that fits you — Leitner, SM-2, or FSRS — none of that one-size-fits-all stuff.
Leitner · SM-2 · FSRSApply
Practice typing, hear native pronunciation, and rehearse the words in context. Decks follow you on browser, phone, and desktop, so the next time you see the word in the wild, you know it.

Relating to the sense of smell.
