Free-tier tools for lesson planning, explanation, materials and marking support — nothing here needs a school purchase order to try.
Flocci AI Tools lists 61 of them, ordered free tiers first: Alibaba Quark AI Assistant, Baichuan Bai Xiao Ying (百小应), Baidu Ernie Bot (Wenxin Yiyan), Falcon LLM Chat (TII) and Google LearnLM. Every one of them is free or has a free tier. Each entry states what it uniquely does rather than a score.
13 on this page are marked fully free with no paid plan at all: Alibaba Quark AI Assistant, Baichuan Bai Xiao Ying (百小应), Baidu Ernie Bot (Wenxin Yiyan), Falcon LLM Chat (TII) and Google LearnLM. The remaining 48 are freemium, trial or paid, and each is labelled with its exact tier so nothing surprises you at sign-up.
They are every catalog entry in 4 sub-categories that map to what teachers and educators actually do: plan a lesson, explain a concept ten ways, build classroom materials, draft feedback. Paid-only tools are excluded from this page on purpose. There is no sponsorship and no paid placement anywhere in the ordering.
