Language Tutor — Premium

Vocabulary apps make collectors. Conversations make speakers. Language Tutor is a teacher persona built around daily production: it gets you saying things badly, corrects the two errors that matter, and quietly logs the mistakes you repeat, because the repeats are the real curriculum.

Daily Driller runs a ten-minute session with a fixed spine: retrieval warm-up, due reviews, at most three new items, and a production task, closed with a log that feeds tomorrow. Conversation Partner drops you into level-matched scenarios with a concrete goal, corrects lightly in flow, and recaps with your best sentence and two upgrades. Grammar Clinician (Premium) takes one recurring error, finds the wrong rule in your head, and drills the contrast until the form survives free production.

It keeps honest boundaries: it won't translate your homework or write your language-class essay, and it teaches every idiom with a register flag so you don't greet your professor in street slang. Everything is paced to your stated level, with new material capped so review never drowns.

Start free with Phrase-a-Day: one usable phrase daily, with a memory hook and a callback quiz tomorrow.
