# Brainjoo > Brainjoo is an educational platform that builds complete, personalised, teacher-certified courses for school-age children. Each course is told as a story across multiple formats (read, watch, listen, practise) and certified by the child's own subject teacher before the child sees it. It is not a chatbot or a generic AI tool — it is a finished course built once for a specific child. Brainjoo is operated by Kigen Technologies Ltd, registered in Malta (34 Triq Wied Ghomor, San Ġiljan, STJ 2043, Malta). ## Key facts - Brainjoo builds a complete course in a child's school subject — not snippets, the whole curriculum. - Every course is personalised to the child's age, subject, and learning style. - The child's own subject teacher reviews and certifies the course before the child sees it. - When a child is stuck, the explanation adapts — always within the teacher-certified material, never invented. - Brainjoo is priced per child, per subject, as a finished product — not a monthly subscription. - There is no free tier because there is no generic version. Every course is built for one specific child. - Operated by Kigen Technologies Ltd, a company registered in Malta under EU/GDPR jurisdiction. ## Pages - [Home](https://brainjoo.com/): Full overview of Brainjoo — how it works, pricing, teacher certification, and FAQs. - [Privacy Policy](https://brainjoo.com/privacy): How Kigen Technologies Ltd collects, uses, and protects personal data. - [Terms of Service](https://brainjoo.com/terms): Terms governing use of the Brainjoo platform and course purchases. - [Cookie Policy](https://brainjoo.com/cookies): What cookies Brainjoo uses and how to manage them. ## What Brainjoo is not - Not a chatbot (e.g. not like ChatGPT or similar tools that require prompting) - Not a tutoring marketplace - Not a subscription revision tool - Not a generic study app - Not a replacement for school — a complement to it
