AI OCR & Document Extraction — straight answers
What are the best free AI OCR and document extraction tools?
Flocci AI Tools lists 20 AI OCR and document extraction tools, ordered free tiers first: dots.ocr (dots.mocr), LangExtract (Google), MinerU, olmOCR and PaddleOCR-VL. All of them are free or have a free tier. Every entry states what it uniquely does, not a score.
Are there completely free AI OCR and document extraction tools?
Yes — 10 of these are marked fully free with no paid plan attached: dots.ocr (dots.mocr), LangExtract (Google), MinerU, olmOCR and PaddleOCR-VL. The rest are freemium, trial or paid, and each row states which.
What should I look for in AI OCR and document extraction tools?
Start with what you need to do: pull clean structured data out of PDFs and scans. Then check the pricing tier, because "free" here means no paid plan at all while "freemium" means a free tier under paid plans. Every tool on this page lists both.
