Stop uploading your brain to the cloud. MindHalo gives you the power of AI tutoring with the privacy of a local app. No data tracking, just pure performance on your Mac.
MindHalo is an intelligent study companion built specifically for macOS.
It combines on-device AI, retrieval-augmented learning (RAG), and motivation systems to help students deeply understand their textbooks not just memorize them.
With Textbook Vault, MindHalo turns your PDFs into an interactive knowledge base you can chat with, quiz yourself on, and generate study materials from — all while keeping your data private on your Mac.
Designed to feel fast, native, and focused, MindHalo helps you study smarter, not longer.
