# NEXA AI resource directory

> AI resources NEXA picked and checked one by one, and ones people recommended after using them, marked as such (130 entries, list 2026-10-17.4-aef10163+8a99140aafa9). Each line: name — what it is for — how an AI connects: entry — address [recommended or alternative · official · last checked] · sign-up & keys · not for (with what to use instead). Lines marked neither recommended nor alternative are further choices in the same zone.
>
> To search by what you need instead of reading everything: `curl 'https://anagent.org/ai/find?q=<what you need>&lang=en'` (best three; add `&format=json` for JSON). NEXA does not store your searches (the web server's access log is kept as usual).
