Every option in the catalog for when you need to pull clean structured data out of PDFs and scans — 11 AI OCR and document extraction tools, 11 of them free or freemium, with the pricing tier printed on every row.
Flocci AI Tools lists 11 of them, ordered free tiers first: Docling, Marker, olmOCR, AskYourPDF and Humata. Every one of them is free or has a free tier. Each entry states what it uniquely does rather than a score.
3 on this page are marked fully free with no paid plan at all: Docling, Marker and olmOCR. The remaining 8 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.
