04Words of nature
Every concept is a term, connected, in every language, with its sources.
Two ways to build it
NEO Library lives on two things only: contributions, and the work of SESY.AI. Both keep knowledge open and never for sale.
Donate on GoFundMe, back us on Kickstarter, become a patron on Patreon, or contribute directly: write on WhatsApp and the librarian sends you the details.
SESY.AI, Semantic Systems & AI: your landing page that sells, free forever for accredited businesses. It earns 5.5% only when you sell, and every client funds the libraries.
