Don’t memorize a language. Have a conversation in it.
An AI tutor immersed in your target language - it talks back, gently corrects you, and turns what you fumble into spaced-repetition flashcards that actually stick.

What are you learning?
19 languages and counting
One agent. Every way to learn.
An immersive AI tutor that places you at your level, runs you along a structured path, keeps score, and remembers everything you've worked on - across every practice mode.
Talk & Learn
An AI agent, not an app
Chat with an agent that replies mostly in your target language - immersion from the first message. It runs the lesson, decides what's worth saving, and builds your deck as you talk.
Placement + learning path
A quick placement test sets your CEFR level, then a structured path of units and lessons takes you from A1 upward - the agent adapts as you progress.
Practice & Remember
Spaced repetition
Cards added mid-conversation enter an SM-2 review queue automatically. The agent decides what's worth remembering.
Writing correction
Paste a paragraph, get inline grading with suggestions. The corrections become flashcards.
Speak & Listen
Pronunciation feedback
Speak each sentence and get word-level scoring vs. the tutor's reading. Tutor audio in 17 of the 19 languages.
Dictation drill
Type what you hear. Tight feedback loop on listening + spelling.
Progress & Motivation
Streaks, XP & achievements
Daily streaks, XP on every review, and badges you unlock as you level up. Gamified so the habit actually sticks.
Daily quests & leaderboards
Three quests a day, a weekly challenge, and a Fluency Readiness Score that tells you what's actually holding you back.

Why learners pick Semantix
Conversation, not tapping
Most apps drill you on words in isolation. Here you produce real sentences from message one, and get corrected the way a tutor would - not marked wrong by a multiple-choice grid.
A deck you didn't have to build
The tutor decides what's worth saving from what you actually struggled with, pairs it with a fill-in-the-blank sentence, and schedules it. No card authoring, no generic 3,000-word list.
A fraction of a human tutor
About what a single lesson with a tutor costs - except it's a whole month, available at 6am or midnight, in all 19 languages, with a 1-week free trial first.
