CurateLM

License-clean multilingual AI training data — 150+ languages, 140+ niches, sourced where Common Crawl doesn't reach.

CurateLM builds commercially licensable text corpora for LLM pretraining and fine-tuning, with a focus on languages and domains that mainstream datasets (Wikipedia, Common Crawl, Project Gutenberg) systematically under-cover.

What makes our data different

• Deep-web & institutional sourcing — archives, government repositories, academic collections, and regional publishers, not just recrawled web text
• Rare & low-resource languages — 150+ languages spanning language families that most training corpora barely touch
• License verified, not assumed — every source is checked and tagged for commercial redistribution rights before it enters the corpus
• Niche domain coverage — 140+ subject niches, from technical and scientific text to regional/cultural material

Who we work with

AI labs and LLM providers looking to close multilingual and low-resource gaps in pretraining data — with clean, traceable licensing you can act on with confidence.
