**Santellissi 2.0 — Read, Study, Reflect, and Create**
Santellissi brings sacred reading, document study, personal annotations, and an offline AI study companion together in one place.

**Meet Brother Lumi**
Brother Lumi is an AI companion powered by a local GGUF language model. Ask questions, explore ideas, and practice conversation without sending your prompts to a remote AI service.

**Built for Learning**
Santellissi combines a PDF reader, page cropping, annotations, document preparation, and AI-assisted discussion in a single learning environment.
Whether you are preparing a lesson, studying Scripture, practicing another language, or gathering passages for a presentation, Santellissi helps you turn reading into meaningful work.
Santellissi is an independent educational application. AI-generated answers may contain errors and should be checked against authoritative sources, especially for theological or historical questions.
