Tongueforge is a spaced-repetition app for people learning properly: typed recall, reading, listening, and a scheduler that brings each word back right when you need it. Then it gives you something no other app can — a conversation partner who speaks only in the words you've actually learned, one new word at a time, and never scores you. No game-layer noise, no guilt.
A conversation partner who speaks in the words you already know — and never scores you. It's the payoff of everything the scheduler has been quietly building.
Your partner draws on the words your reviews say you know, and brings in at most one new word at a time. Tap a new word to add it to your reviews — the conversation feeds the same memory system that made it possible.
Nothing you say is scored or corrected mid-conversation. Afterward, a short note points out at most a couple of phrasings worth a second look. No counts, no red marks, nothing to protect.
Order the coffee, book the table, sort out the ticket — conversations have a point to reach, not just a prompt to answer. Something real coming up? Describe it and rehearse it first, in your own words.
Each language has its own partner, so conversations keep a consistent voice and pick up where you left off. Want the grammar behind a sentence? Ask, and the app explains it — your conversation stays just a conversation. It runs on a large language model through Tongueforge's own service; only your text ever leaves your device.
Tongueforge is designed for adult learners reactivating dormant skills or building real production ability, not casual tap-through practice.
