ideAI is the privacy-preserving memory and context layer for humans and AI. You can't see your own cognitive patterns. Your AI can't remember yesterday. ideAI closes both gaps — an encrypted, on-device memory layer that you browse as a semantic atlas, and your AI tools access via MCP. One data layer. Zero trust required. FOR YOU: THE ATLAS Import your digital history — journal entries, Twitter, Reddit, Claude, ChatGPT conversations — and watch it compress into a navigable topology. Day summaries. Week and month views. Semantic collision graphs that show where your thinking clusters, diverges, and evolves across time. FOR YOUR AI: DATASHARD Give any AI you already use — Claude, ChatGPT, Cursor — secure access to your Atlas via MCP. Every conversation starts with your full context, not a blank slate. Your AI finally has a memory. ON-DEVICE AI INSIGHT Chat with an on-device AI that has full context of everything you've written. It surfaces temporal patterns, semantic collisions, and recurring themes across months and years. Not advice — structure. ZERO-KNOWLEDGE PRIVACY AES-256-GCM encryption. On-device processing via Apple Foundation Models and MLX. Your data stays on your device. No servers see your content. No model trains on your thoughts. DATA SOVEREIGNTY You own all data in portable formats. You control all processing. You can export, delete, or migrate without loss. The value is in the instrument, not data captivity. Free to start. No account required.
