The fun part
Pick a tutor with personality
Same accurate corrections — wildly different delivery. Click any tutor to see how they give feedback. From a chivalrous knight to a cave goblin — show up because you want to.
How it works
A feedback loop, not flashcards
Most tools stop at the correction. dojo turns every mistake you make into your next lesson — so the same errors stop coming back.
Write something real
Three ways in: free-write with no prompt, answer a journal prompt at your level, or translate English into your target language. Your words, your voice — never multiple choice.

FAQ
Before you start writing
How is this different from just using ChatGPT?
A blank chatbot makes you do all the work — set it up, paste your text, decide what to ask, and start from zero every session. dojo is the whole loop, already built: instant scored corrections in your tutor's voice, every mistake remembered and distilled into a focused lesson plan, then turned into Missions that drill your weak spots — with streaks and stats that pull you back. You just write.
Which languages can I learn?
Over 30 — including Japanese, Chinese, Korean, Spanish, French, German, Arabic, Hindi and many more, plus a few fan-favourite conlangs like Klingon. Switch whenever you like — your streak, stats and progress are kept separately for each one.
How accurate are the corrections?
Corrections are fully AI. The model checks script, accents, grammar and word choice against a native-level standard, then gives you the minimal fix that keeps your voice. Like any AI it can occasionally slip on edge cases — but you're never left guessing: ask your tutor why, in plain English, until the rule behind any correction clicks.
Do I need to already know the language?
No. Start from scratch with a guided prompt, translate from English, or free-write whatever you can — even a few shaky words. dojo meets you where you are and corrects what you actually produce.
Is my writing private?
Yes — your data is safe with us. Everything you write travels over an encrypted connection and sits behind strict access controls.
We only ever process your writing as much as we genuinely need to. To give you feedback, it has to reach the AI that grades it (Google's Gemini); to show your progress, we keep your sessions and corrections in your account — and that's really all. We never sell it, never trade it, and never hand it to anyone beyond the services that keep dojo running. See our Privacy Policy for the full details.
What does it cost?
dojo is in early access while we onboard our first writers. We'll post full pricing here before opening it up to everyone.
