Landit — The grammar was perfect. So why did your roommate's face freeze? "I don't care" is a grammatically perfect sentence. But to a native speaker, it might not sound like "Whatever works for me" — it can sound like "I couldn't care less." The problem isn't grammar. It's nuance. Your words are correct, your grammar is correct, but no one tells you how your English actually landed. If you've ever studied abroad, lived with a foreign roommate, and felt things get quietly awkward for no clear reason — this might be why. Landit is a speaking practice app set in the world of living with a foreign roommate. Have 1:1 English conversations with an AI roommate and find out, in the moment, what nuance your English actually carries to a native speaker. -- [Raedi tells you what your roommate is really thinking] Landit has Raedi. Every time you speak, Raedi shows up and tells you, right then and there, how your roommate really felt inside. "Oh, you explained why? We're really connecting!" "They tilted their head a bit. Try slowing down next time!" See your roommate's real reaction in real time, so you know instantly whether your English landed or missed. -- [How Landit works] Every session follows four steps: today's scenario → AI conversation → personalized feedback → expression practice. 1. Today's scenario One new scenario a day — talking about food preferences, weekend plans, your favorite movie, the kind of everyday conversation you'd actually have with a roommate. You don't pick from a list; a new one unlocks each day, each with a clear goal, so you're never just talking — you're practicing with a purpose. 2. Real-time conversation with your AI roommate Speak out loud and your AI roommate responds in real time. Every time you talk, Raedi lets you know what your roommate is really thinking, so you can see how your words landed as the conversation goes. 3. Personalized feedback When the conversation ends, you get a detailed report. Not just "right" or "wrong" — it shows you how your English actually sounded to a native speaker, plus a more natural way to say it. Tricky expressions are explained with "here's what that sounds like in Korean," so the nuance gap clicks instantly. 4. Make it yours with expression practice Expressions you missed during the conversation are saved as cards. Flip through them, then write them out yourself in a review exercise to make them fully your own. -- [What makes Landit different] ■ Native comprehension score • Every conversation shows you a native comprehension score — how much of what you said a native speaker actually understood. • See at a glance how well your English is landing with native speakers right now. ■ What a native speaker actually heard • What matters isn't whether your sentence was technically correct — it's how the other person understood it. • Landit analyzes how much of your meaning actually came across, based on what the AI truly understood. ■ Here's how it lands better • Awkward phrases get swapped for more natural ones. • You'll also learn why the natural version actually lands better. -- [This is for you if] • You're heading into a study abroad or exchange program and English conversation makes you nervous • You've had a foreign roommate or friend, and something felt subtly off without knowing why • You know the grammar but wonder how your English actually sounds • You need real, everyday English — not test English • You want an efficient way to practice speaking in short bursts -- [Permissions] All permissions are optional. You can use the app without granting them, minus the features that require them. • Microphone: used for speech recognition during speaking practice -- Start your first conversation with Landit today, and speak English that actually lands.
