A Local-first Multimodal Dental AI Assistant for Dental Workflows

The Multimodal Dental AI Assistant is a local-first PyQt6 desktop application designed for dental
workflows. It integrates several AI-powered tools, including conversational chat, document question-answering,
spreadsheet analysis, and dental image analysis, all running against local Ollama language models.
Per-user history is persisted under history/ with optional Fernet encryption when the cryptography
library is available. All AI inference is performed locally through Ollama; no cloud API keys are required. User history is
isolated by account, and dental image analysis is explicitly informational only and must never be used as a
clinical diagnosis.
