About Arca School

Arca School is a classical education platform built with modern engineering. We believe the Trivium — Grammar, Logic, and Rhetoric — remains the most powerful framework for developing clear thinking.

The Vision

A platform where students write essays guided by the classical method, with AI that assists in the margin rather than replacing the student’s voice. The text is sacred; the AI is a scribe, not an author.

The Stack

Every component is written in Rust. The editor (Scriptorium) runs natively on desktop and compiles to WASM for the web. The inference engine (slm-engine) serves specialized small language models. The knowledge pipeline (arca-rag-math) handles mathematical content with LaTeX precision.

The Team

Founded by Diego Bonesso — mathematician, engineer, and classical education advocate. Based in Porto Alegre, Brazil.
