FAQ
Frequently asked questions
Everything you need to know about Thalia.
Never. Thalia is designed with strict pedagogical rules — it uses Socratic questioning, progressive hints, and metacognitive coaching to guide students toward understanding. Giving direct answers is explicitly forbidden in the system.
Thalia works with any course that has digital materials. It's especially powerful for STEM courses with formulas, diagrams, and problem sets. Current deployments include electrical engineering, computer science, and machine learning courses.
Thalia ingests your course materials (PDFs, slides, documents) and creates a searchable knowledge base using FAISS vector indexing. When a student asks a question, the system retrieves relevant snippets from your actual materials to ground every response.
Absolutely. Thalia is FERPA and GDPR compliant. Student identifiers are SHA-256 hashed before storage. No personally identifiable information is ever stored in our analytics database.
Yes. Students can upload photos or scans of handwritten solutions, and our vision-powered system (using GPT-4o) can read and analyze their work — including formulas, diagrams, and circuit drawings.
Most courses can be indexed in under 15 minutes. Upload your materials, run the ingestion pipeline, and your AI tutor is ready. Vision processing for images and formulas adds a small one-time cost.
