# Sagius

> Sagius is a philosophy companion app (iOS and Android) with a fully static,
> crawlable website. It pairs a curated catalog of real philosopher quotes with
> honest, clearly labeled AI-assisted explanations and mentor-style
> conversations, in five languages (English, French, Portuguese, German,
> Spanish).

The app catalog currently holds 6,600+ curated quotes from 230+ philosophers. This website publishes a smaller explained subset (the thinkers and topics listed below) as crawlable HTML.

All quote explanations and mentor replies are AI-generated and are labeled as
such on every page — no AI text is presented as human-authored. Quotes
themselves come from the curated catalog of real philosophers.
