Names are taken from multiple sources, mostly LOTR wikis including The Notion Club Archives and then put into ChatGPT. ChatGPT is asked to either put the names into a fitting format or try to come up with new names in the same style, the majority is taken directly from notionclubarchives.fandom.com and gets put into the compatible format. Bear in mind that this is not supposed to be completely similar to the style of the actual names Tolkien used, some are taken from his creations, some are taken from Tolkien-inspired or tolkien-based sources featured on the website.
There is also an alternative version with older and unsorted namebases. The Valarin and Old Entish names were taken from ChatGPT while the Melkian and Ilkorin & Doriathrin ones were put into a markov generator as there weren’t enough samples to meet the required number of words & variety.
All 34 available bases are as of the 1st of November 2023: Adûnaic, Avarin, Blackspeech, Dale, Dorwinic, Drúedain, Dunlendic, Eastron, Edainic, Entish, Goldogrin, Halethian, Haradric, Hillman, Hobbitish & Breeish, Ilkorin/Doriathrin, Khandic, Khuzdul, Lossoth, Melkian, Nandorin, Noldorin, Old Breeish & Eriadorian, Old Gondorian, Orcish, Primitive Elvish, Quenya, Rhovanian, Rohirric, Shire, Sindarin, Telerin, Valarin, Westron
