ChatGPT is the AI everyone's heard of — but for a teacher, is it actually the best tool for the job? Often not. For school tasks, purpose-built education tools frequently beat ChatGPT on ease, safety and results. Here's the honest answer.
The short answer
For general questions, ChatGPT is excellent. But for the specific jobs a teacher does every day — planning lessons, writing reports, making differentiated resources — purpose-built school AI tools are often better than ChatGPT, because they're designed around exactly those tasks and built with school data safety in mind. "Better" depends entirely on what you're trying to do.
Why ChatGPT isn't always the best choice for teachers
ChatGPT is a blank box. It can do almost anything, but only if you know how to ask — and getting a genuinely useful report comment or a curriculum-aligned lesson plan out of it takes skill and time. It also isn't built for schools: the free version has data-handling concerns, and it doesn't know your curriculum. For a busy teacher, that's a lot of friction.
Tools that often beat ChatGPT for school tasks
These are built specifically for education, so they remove the "knowing how to ask" problem:
- Teachmate — the UK's most widely used teaching toolkit, 150+ tools for planning, reports and resources
- MagicSchool — 80+ teacher tools with a strong free tier
- SLT AI — purpose-built for school leaders
- Oak's Aila — free, curriculum-aligned lesson planning

The honest nuance: the "best" tool isn't a fixed answer — it's the one that fits your task and your school. A purpose-built tool wins for everyday teaching jobs; ChatGPT wins for open-ended thinking and one-off questions. Many teachers use both.
When ChatGPT IS the right choice
ChatGPT still shines for brainstorming, explaining a tricky concept, drafting a one-off email, or thinking through a problem. If you want a general assistant rather than a teaching-specific tool, it's excellent — just learn a few prompting basics and mind what data you put in. See using AI responsibly in school.
How to actually decide
Don't agonise over picking the single "best" AI. Start with the task that eats most of your time, try a purpose-built tool designed for it, and see if it helps. The right answer becomes obvious quickly once you're using the right tool for the right job — and that's exactly the kind of thing worth having someone to guide you through.
