Every option in the catalog for when you need to find, screen and summarise peer-reviewed papers — 16 AI tools for academic research, 15 of them free or freemium, with the pricing tier printed on every row.
Flocci AI Tools lists 16 of them, ordered free tiers first: Ai2 Paper Finder (Asta), alphaXiv, ResearchRabbit, Semantic Scholar and PaperQA2. 15 of the 16 are free or have a free tier. Each entry states what it uniquely does rather than a score.
5 on this page are marked fully free with no paid plan at all: Ai2 Paper Finder (Asta), alphaXiv, ResearchRabbit, Semantic Scholar and PaperQA2. The remaining 11 are freemium, trial or paid, and each is labelled with its exact tier so nothing surprises you at sign-up.
Free tools first, then freemium, then trial, then paid, and alphabetically inside each tier. Nobody pays to appear higher: Flocci AI Tools carries no ads, no sponsored slots and no paid listings, so the order reflects price and nothing else.
