## What is Lexicon?

Stop studying languages. Start speaking them.

Forget about the language barrier and the fear of making mistakes. With Lexicon, you can practice English, Spanish, French, or German in live AI chats. It feels just like texting a native-speaking friend, but without the anxiety, available anytime you want.

REAL CONVERSATIONS, NOT TEXTBOOKS
Chat with 30+ AI characters, each with their own unique personality and backstory. Discuss fashion with Sloane, debate tech with Dan, or gossip with Lola. Every conversation adapts to your level — no scripted dialogues or robotic replies.

CAN'T FIND A PARTNER? CREATE ONE
Build your ultimate conversational partner: set their personality, profession, and tone. Prep for a job interview, practice ordering food abroad, or just chat about your hobbies in your target language.

EVERY MISTAKE IS A STEP TOWARD FLUENCY
Lexicon checks your messages in real time and explains your mistakes in your native language. It doesn't just say "wrong" — it shows you WHY it's incorrect and HOW to sound natural.

UNDERSTAND CONTEXT, NOT JUST WORDS
Tap any word in the chat to get more than just a translation. Get full definitions with examples and nuances. Different meanings are separated so you always grasp the exact sense in your specific context.

SAVE WORDS. LEARN THEM. REMEMBER FOREVER.
Add words and phrases to your custom decks. Review them with smart flashcards based on spaced repetition — the scientifically proven method used by top polyglots worldwide.

EVERY RULE, ALWAYS AT HAND
Got stuck? Open the built-in grammar library, structured by CEFR levels (A1–C2). Clear, bite-sized theory means the answer is always just one tap away.

SMARTER THAN EXPENSIVE TUTORS
A whole month of active practice in Lexicon costs less than one hour with a private tutor. Practice in a comfortable environment where it's safe to make mistakes.

YOUR PRIVACY MATTERS
Ad-free. No data selling. Your conversations are strictly private.

• Languages to learn: English, Spanish, French, German.
• Interface languages: Russian, English, Spanish, French, German, Arabic, Chinese, Hindi, Japanese, Portuguese.
