WHY CATLANGU
► Learn the 2,500 words that unlock 90% of daily English
Most apps teach you to recognize English, not speak it. Every word comes with its meaning, a translation, and a real sentence — all with native audio. Hear it, type it, then say it out loud. That's how vocabulary becomes something you use, not just something you recognize.
► Practice English with AI, 24/7
Talk freely with Ava, your AI English partner. She adapts to your level and corrects you as you go — no schedule, no pressure. Practice by text or by voice whenever you have ten minutes.
► Rehearse 65 real-life scenarios
Practice the conversations you'll actually have: a job interview, a doctor's visit, ordering food, asking for directions. Ava stays in character while you run the same situation as many times as you need.
► Speaking practice with other English learners
When you're ready for a real conversation, Catlangu connects you with another English learner for a live voice practice session. Everyone is there for the same reason — to practice English. You can also invite a specific learning partner to practice together whenever you both have time.
► English speaking groups — up to 8 learners
Join a group room, pick your topic and level, and practice speaking together. Ask questions, make mistakes, and help each other improve.
► Shadowing practice with real English videos
Turn any YouTube video into a private pronunciation lesson. Listen to a native speaker, repeat sentence by sentence, and build real rhythm, accent, and fluency.
► Messages with instant corrections
Write to other learners by text or voice note and get your English corrected right inside the conversation. Practice speaking together by voice when you're both ready.
► A community of 300,000+ English learners
Post in English — text, photos, or voice notes — and get real feedback and corrections in the comments. You're never practicing alone.
BUILT FOR REAL GOALS
Preparing for IELTS or TOEFL, getting ready to study abroad, speaking English at work, traveling with confidence, or finally watching movies without subtitles — Catlangu is built to get you speaking.
