How YAKKI uses AI
“AI-powered” can mean anything. This page says precisely what the AI in YAKKI does, what it never does, and which guardrails stand between a language model and a child.
What the AI does
Two jobs, clearly bounded
Generates exercises live
When a teacher or student picks a topic, level, and game format, the content for that exact combination is generated on our servers at that moment. This is why YAKKI has no “exercise bank” to run out of — and why any topic works, including the one your class discussed this morning.
Reviews free answers
When a student writes or says an open answer, AI evaluates it and explains — what works, what doesn’t, and why. Not a red X, but the kind of specific feedback a teacher would give if there were time to give it to every student on every answer.
What the AI never does
The boundaries, in writing
No open chat with children
There is no free-form chatbot. The AI works inside structured game formats with defined inputs and outputs — a student cannot wander into an unscripted conversation with a language model.
No autonomous pedagogy
The teacher chooses topic, level, language, and formats. The AI fills the frame the teacher built; it does not decide what a child should learn.
No data mining of students
Guest mode means lessons run without student accounts or personal profiles. We do not build advertising profiles, we do not sell data — there is barely any personal data to sell.
No unreviewed content
Generated content passes automated validation before reaching a student, and every game format went through structured multi-model and human review during development.
Guardrails
Between the model and the classroom
- Teacher-controlled frame — topic, CEFR level, and native language are set by an adult, not inferred by a model
- Structured formats — generation fills strict game templates, not free text to children
- Automated validation — generated content is checked before display; failed generations are retried or rejected
- Level gating — content is constrained to the chosen CEFR level, so a beginner is not handed C1 text
- Server-side processing — generation and review run on our servers; the app on the device stays thin
Honest limits
What we will tell you before you ask
Generation can fail
Live generation occasionally produces a flawed exercise. Validation catches most; teachers see and can skip the rest. We log, fix formats, and retest — continuously.
AI review is not a teacher
Answer review is consistent and instant, but it is feedback on language, not a relationship. YAKKI is built to give teachers leverage, not to replace them.
Methods are proprietary
How exactly generation and validation work — prompts, models, pipelines — is our commercial core and is not published. What it does and the guardrails around it are exactly as stated on this page.
Evaluate it live
The honest way to assess AI in education is to watch it work with your own topics. We will run any topic you name, at any level, live.
