Your life is the lesson
Turn everyday life into situational fluency.
Say the phrases you actually need, in the situations you actually face. Capture a real moment, get a short lesson built from it, and review it until it sticks.
Situations LangBytes turns into lessons, with a phrase for each:
- At the ramen counter: ラーメンをください。 (“Ramen, please.”)
- Lost near the station: 駅はどこですか？ (“Where is the station?”)
- First day at work: よろしくお願いします。 (“Nice to work with you.”)
For adults 21+ · Invitation-only founding beta

FAQ
Questions before you join
What is LangBytes?
A language app built around your own life. You capture a phrase from a real moment, confirm what you were trying to get done, and get a short lesson: the lines you need, the replies to expect, and what to say when it goes wrong. Spaced review brings those lines back until they stick.
Who is it for?
Adults aged 21 and over who want to handle real situations in another language. Accounts are invitation-only during the founding beta.
Which languages can I learn?
Every language pair offered today is listed under Languages, with the most complete marked.
