Every option in the catalog for when you need to read a pile of sources and get a grounded report — 6 AI deep-research and document tools, 5 of them free or freemium, with the pricing tier printed on every row.
Flocci AI Tools lists 6 of them, ordered free tiers first: STORM (Stanford), ChatGPT Deep Research, ChatPDF, Gemini Deep Research and NotebookLM. 5 of the 6 are free or have a free tier. Each entry states what it uniquely does rather than a score.
1 on this page are marked fully free with no paid plan at all: STORM (Stanford). The remaining 5 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.
