# Sudar — AI-Powered Learning Operating System

> Learns with you, for you.

Sudar is an open, AI-native Learning Operating System for corporate training and education. It combines authoring (Sudar Studio), personalized delivery (Sudar Learn), and an adaptive AI engine (Sudar Intelligence) so L&D teams can build world-class training without an army of instructional designers.

## Open Source & Free Forever

Sudar is **forever free** to self-host on $0 infrastructure tiers. Dhanikesh "Dhani" Karunanithi created Sudar to make AI-powered education more **open, free, and accessible** — equal opportunity for all learners and builders across the inter-tech space.
