LUDIA = AI + UDL
LUDIA is a no-cost chatbot designed by educators, for educators. The goal behind designing LUDIA is simple: Universal Access to Universal Design for Learning. LUDIA is universally designed to be accessible, safe, and private.
- No cost, with no catch. No subscriptions, premium tier, paywalls, or trial.
- Designed for accessibility. Built and tested to WCAG 2.2 Level AA.
- Ad-free. No advertisements, sponsored content, or commercial referrals.
- Private by architecture. No account, no profile, and no chat content stored on LUDIA's servers. You can download your conversations.
- Design-first. Every response focuses on barriers in the design of learning, not in the learner.
- Multilingual. LUDIA answers in 13 languages, with more being added.
"Access to the AI-powered thought partner LUDIA gave our teachers immediate confidence, providing them with the practical resources and time-saving tools needed to meaningfully embrace learner variability and support every student in their classrooms." Rebecca Toth Juras | Director, Vilnius International School
