CrossTalkbyArnoLearn a language by chatting with an AI partner.
CrossTalk is a chat app built on the linguistic method of the same name: you write in your own language, your AI partner replies in the one you're learning. It's the comprehensible input approach Stephen Krashen showed is how humans actually acquire language.
A chat app that teaches you a language while you use it.
No lessons, no flashcards, no streaks. You just have a conversation, and the app does the teaching in the background. Here's the whole loop in three steps.
Pick a language and a topic
Choose any of 30+ languages, then start a chat about whatever you want, your trip to Kyoto, your job, last night's dinner. There's no fixed curriculum.
Chat in your language, get replies in theirs
Type or speak in the language you already know. Your AI partner replies in the language you're learning, at a level just slightly above yours so it stretches you without losing you.
Tap to learn, never get stuck
Don't know a word? Tap it for a translation. Still confused? Tap “I'm lost” and CrossTalk pauses the chat for a 90-second mini-lesson, then drops you right back into the conversation.
Three things every chat does for you.
A real conversation is doing three jobs at once. CrossTalk is built so every message you send and every reply you get pushes all three of them forward.
Real conversation, not lessons
Skip the curriculum. You chat about what you actually care about, and your partner replies in the language you study, every single turn.
- Choose any topic, any time
- Native-language fallback whenever you need it
- Listen, type, or speak, all in one chat
Mini-lessons exactly when you get lost
Tap any word or phrase and get a 90-second tutor explanation tailored to that moment. Then drop right back into the conversation.
- Triggered by your real confusion
- 3 modules, ~90 seconds, then back to chat
- Builds on the sentence you just saw
A partner that learns your level
CrossTalk by Arno reads every reply you send and tunes its vocabulary, grammar, and pace to sit just above your current ability. Always learnable, never boring.
- Detects your CEFR level continuously
- Stretches you with i+1 input
- Slows down or simplifies when you struggle
Confused for a second? Get a 90-second lesson.
When a word, phrase, or grammar pattern trips you up, CrossTalk by Arno pauses the chat and runs a tiny three-module lesson built around what you just saw. You finish in under two minutes and the conversation picks up exactly where you left off.
- Triggered the moment you tap “I’m lost,” not at a fixed schedule
- Pulled from the exact sentence you didn’t understand
- Resumes the conversation with the new word ready to use
Your partner gets to know you, not the other way around.
Most apps make you pick a level once and call it a day. CrossTalk by Arno re-estimates your comprehension after every message and shifts the conversation up or down so it always sits in your sweet spot, that magic place just past what you already know.
- Reads your replies for grammar range and vocabulary depth
- Picks new structures and words slightly above your level
- Backs off and rephrases the moment you stop following
The CrossTalk by Arno method, in three habits.
Borrowed from second-language acquisition research and tuned for conversation.
Listen for meaning first
Hear input that is just above your current level. That stretch is where new words become learnable.
Reply naturally
Answer in your native language or the one you study. Just keep the conversation moving.
Use text after listening
Try to grasp the audio first, then peek at text or translation to confirm what you caught.
