Everything here has a free tier, so a student can finish an assignment, a lab report and a slide deck without a card on file.
Flocci AI Tools lists 89 of them, ordered free tiers first: Ai2 Paper Finder (Asta), Alibaba Quark AI Assistant, alphaXiv, Baichuan Bai Xiao Ying (百小应) and Baidu Ernie Bot (Wenxin Yiyan). Every one of them is free or has a free tier. Each entry states what it uniquely does rather than a score.
18 on this page are marked fully free with no paid plan at all: Ai2 Paper Finder (Asta), Alibaba Quark AI Assistant, alphaXiv, Baichuan Bai Xiao Ying (百小应) and Baidu Ernie Bot (Wenxin Yiyan). The remaining 71 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 7 sub-categories that map to what students actually do: understand a hard topic, find and screen sources, take and organise notes, build a presentation, check and tighten writing. Paid-only tools are excluded from this page on purpose. There is no sponsorship and no paid placement anywhere in the ordering.
