ChatGPT vs Claude vs Gemini for Lesson Planning – A Practical Comparison
Career and tech teacher in Quebec. I’ve been using all three AI tools for lesson planning over the past term and want to share what I’ve found for each use case.
ChatGPT (GPT-4o): best for generating varied activity ideas quickly. if you need 10 different formats for a concept, ChatGPT generates the broadest spread. good for brainstorming sessions.
Claude: best for longer, more coherent content. if you need to write a complex project brief or a nuanced rubric that hangs together logically, Claude is more consistent over long documents. also better at maintaining a consistent tone.
Gemini: integrated with Google Workspace which matters if you’re a Google school. the integration saves time even if the raw output quality is slightly behind the others.
For job-market focused content (my main area): all three are underinformed on Canadian labour market specifics. you have to bring that knowledge yourself and use the AI to structure and communicate it.

switched from ChatGPT to Gemini for differentiated materials after reading something similar. haven't looked back. the formatting is cleaner and it handles tables and structured outputs better for the kind of worksheets I make.
YES!! The Google Workspace integration point is SO useful for my school!! We're a Google school and the Gemini integration actually saves me time even when the output is slightly less good. Sharing this comparison with my whole department immediately.
Wendy's enthusiasm for Claude tracks with my experience - the longer context window is genuinely useful for lesson planning because you can feed it a full curriculum document and have it plan within actual constraints. the other tools hit limits faster. for unit-level planning it's noticeably better.
the bilingual support question matters a lot for our school. ChatGPT handles French-English mixed content better than Gemini in my testing. less mixing of language conventions when you prompt in one and ask for output in the other.
the Canadian specificity gap is real across all of them. I've found Claude slightly better at acknowledging what it doesn't know about Canadian curriculum specifics rather than hallucinating provincial details. but none of them are reliable on province-specific curriculum standards.
