Short answer: it can draft them; it can't finish them. AI is genuinely good at the mechanical parts of planning — structuring a lesson, generating three starter options, drafting differentiated task instructions. What it cannot do is know your class: yesterday's misconception, which pupils need scaffolding today, how this group responded to a similar activity last term.

The workflow that works

Describe the objective and year group, ask for starter ideas and a main activity structure, then rewrite the output in your own words and adjust it for your actual class. That final edit is what keeps the lesson yours — and it's also where your professional judgement earns its keep. Most teachers find this cuts a thirty-minute plan to about ten. Our full guide to AI for lesson planning includes prompts that work.

What to watch for

AI-generated plans can be plausibly wrong — a maths progression that skips a step, an activity that assumes prior knowledge your class doesn't have. Read everything as a keen trainee's first draft, not a finished product, and the risk disappears.
