The Approach
Built with AI, not an engineering team
Built using Claude Code — a conversational AI coding assistant. You describe what the tool should do in plain English, and it writes production-ready code
Rapid iteration with real students — build a prototype in the morning, test it in the afternoon lesson, refine based on what actually happened in the room
No engineering team, no budget, no procurement — just one classroom teacher who understands the problems students face every day
Domain expertise is the superpower — AI handles the code, but knowing which pedagogical problems to solve and how students learn is what makes the tools effective
The Bigger Picture
What this means for schools
Scalability
Serve an entire department, not just one teacher — the same platform handles any subject with exam-style questions and mark schemes
Cost
Less than a single textbook set per year — no expensive licenses, no per-seat fees, no procurement process
Data-Driven Insights
Real-time visibility for everyone — teachers, students, parents and leadership see progress instantly, not at parents' evening
Fairness & Equity
Blind marking removes unconscious bias — consistent AI feedback means every student gets the same quality, regardless of who marks their work

About
Mike Lehnert
Music technology teacher. AI tool builder. Helping educators figure out what actually works.
After 20 years in the classroom — in schools, at Leeds Conservatoire, as a Pearson examiner — I started using generative AI seriously about three years ago. More recently, I've been building tools with Claude Code, Obsidian, Gemini, and NotebookLM. My approach is to use multiple AI systems rather than locking into one — different tools for different jobs.
I've built an Obsidian vault system for organising teaching materials, developed grading and feedback tools, and created interactive resources for A-Level Music Technology. I've documented this work on YouTube to help other educators explore what's possible.
What I've found is that AI works best when it walks alongside you as a teaching assistant — not doing the work for you, but helping with the repetitive stuff so you can focus on actual teaching.
Schools need help figuring this out. Most AI advice is either too abstract or comes from people who haven't been in a classroom recently. I'm still teaching daily, so I know what actually works and what doesn't.
Open to consulting, training, and collaboration with schools ready to integrate AI properly.
