For parents, teachers and schools
A general AI will answer anything. Mr Jarven only answers school.
ChatGPT, Gemini and Claude are excellent general assistants — built for adults, for any topic, with no idea that the person typing is thirteen and supposed to be doing maths. Mr Jarven is the opposite kind of tool: one purpose, a narrow scope, and a clear answer to the question every parent actually asks — what happens when my child types something else?
Free plan: 5 questions a day. No credit card.
The difference is scope, not intelligence.
A general chatbot is designed to be useful to everyone about everything. That is exactly what makes it a poor fit for a school desk. It has no reason to refuse a question about a violent film, a diet, a rumour about a classmate, or how to word a message to someone the student shouldn't be messaging. It will also happily produce a finished essay, which is the fastest way to learn nothing.
Mr Jarven is deliberately narrow. It knows it is talking to a student, it knows the conversation is about schoolwork, and it treats everything else as out of bounds. Narrow scope is not a limitation here — it is the whole product.
Side by side, honestly.
General assistants are compared here as a category — ChatGPT, Gemini, Claude and similar. They are strong tools. They are just not school tools.
What it is built for
General AI: Everything — work, code, relationships, adult topics, entertainment.
Mr Jarven: One job only: helping a student understand schoolwork.
Off-topic questions
General AI: Usually answered. The model has no reason to say no.
Mr Jarven: Politely declined and steered back to the subject being studied.
Age of the intended user
General AI: Terms typically require 13+ (or 18+ without a parent). Built for adults.
Mr Jarven: Designed for school-age students, with answers tuned to their level.
Homework behaviour
General AI: Hands over the finished answer if you ask for it.
Mr Jarven: Explains the reasoning step by step so the student can do the next one alone.
Attempts to bypass the rules
General AI: Jailbreak prompts circulate widely and often work for a while.
Mr Jarven: Prompt-injection and role-play bypasses are detected and refused.
A student in distress
General AI: Response varies. It is a general assistant, not a school tool.
Mr Jarven: Responds with care and points the student to a trusted adult.
What a parent or teacher can expect
General AI: An open-ended assistant with no school-specific boundaries.
Mr Jarven: A predictable tutor with a scope you can explain in one sentence.
What actually happens when a student types something else.
Four layers sit between the question and the answer.
01
Input filtering
Every message is scanned before it reaches the model. Prompts about self-harm, sexual content, violence, drugs or other adult topics never get answered as if they were homework.
02
Education-only responses
Mr Jarven has a single instruction it cannot be talked out of: help with school subjects. Anything outside that — dating advice, adult humour, buying things, personal opinions about people — is declined and redirected.
03
Anti-jailbreak
"Pretend you are a different AI", "ignore your instructions", "it is for a story" — the classic bypasses are recognised as bypasses and refused with a short explanation rather than a lecture.
04
Wellbeing
If a student sounds anxious, overwhelmed or unsafe, Mr Jarven does not try to be a therapist. It answers kindly and encourages the student to speak to a parent, teacher or counsellor.
It teaches. It doesn't just answer.
Ask a general chatbot to solve an equation and you get the solution. Ask Mr Jarven and you get the method, one worked example, and then the next step handed back to the student.
When the explanation is still too hard, the student can ask for it again in simpler words — down to an explanation a ten-year-old would follow. When it lands, a quiz or a flashcard deck can be generated from the same material to check that the understanding survived the evening.
That is the difference between finishing the homework and learning the topic.

GDPR, processed in Europe
Student data is handled under European privacy rules, and we only store what is needed to run the account.
No training on your data
Conversations are never used to train AI models. A homework session is not a data donation.
Age-appropriate by default
Explanations adapt to the level of the student instead of assuming an adult reader.
Built with teachers
The tutoring behaviour was shaped with input from teachers and reviewed against child-safety guidance.
No AI tutor should be sold as perfect supervision, and we don't. Mr Jarven narrows what a student can do with AI during homework; it does not replace a parent or a teacher. Read the privacy policy or ask us anything.
Fair questions.
Is ChatGPT bad for my child?
No — general assistants like ChatGPT, Gemini and Claude are genuinely impressive tools, and their makers do safety work. They are simply built for adults doing anything at all. An open assistant with no subject boundary will discuss almost any topic a curious 12-year-old types in, and it will hand over a finished essay if asked. That is a mismatch with schoolwork, not a scandal.
Does Mr Jarven use the same underlying AI?
Mr Jarven is built on leading language models, the same class of technology. The difference is everything around the model: the instructions, the filtering, the refusals, the tutoring style and the fact that it has exactly one purpose.
Can a student get around the restrictions?
No system is perfect, and we will never claim otherwise. What we can say is that bypass attempts are actively detected rather than ignored, and that the scope is narrow enough that off-topic answers stand out instead of blending in.
Will it just do the homework for them?
That is the behaviour we designed against. Mr Jarven explains the method, works through an example and then asks the student to try the next step — and it can generate quizzes and flashcards to check whether the understanding actually stuck.
Can schools use it?
Yes. The scope, the refusal behaviour and the data handling are the three things schools usually ask about, and all three are covered above. Get in touch if you need something in writing for a procurement process.
