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.

Stop fighting with copy and paste. Page is one inbox every machine you own can write to. Clip a note, a link, an error, a command, a number you will need in an hour — from a terminal, a script, or an AI coding assistant. It is on your phone before you have switched windows. FOUR KINDS OF PAGE NOTES — save this for me. REMINDERS — bring this back at nine. UPDATES — tell me when the build finishes. QUESTIONS — I need you to decide. Questions are the part nothing else does. When an agent asks "the migration is ready, deploy?", it stops and waits. You tap Deploy or Review first on your phone, and the answer goes back to the terminal that asked. READ IT THE WAY YOU THINK Timeline puts the day in order. Tree groups by the machine that paged you, which is what you want when a dozen hosts are talking. Project groups by the code you were working in. Markdown renders properly and long logs stay collapsed until you open them. BUILT FOR THE PLACE IT LIVES Swipe to pin or delete. Search across everything loaded. Copy a page, or send it to Reminders, Calendar, or anywhere else. On iPad it reads like Mail, list beside page. Answer from the notification without unlocking into the app. WORKS WITH WHAT YOU ALREADY RUN A one-line install adds the page command to your shell, and an MCP server so agents can both reach you and read the inbox back. "Page me when the build finishes" and "ask me before deploying" become things you can just say. FREE AND PRO Free includes the full inbox, email delivery, and a rolling 30-day history — pin anything you want to keep past that. Pro is $7.99/month, adds push notifications and SMS, and keeps every page for good. SECURITY Page content is encrypted at rest with AES-256-GCM, and every connection is HTTPS. API tokens are stored as hashes, never in the clear, and the token on your device lives in the Keychain. PAGE PRO Page Pro is $7.99 per month. Payment is charged to your Apple Account at confirmation of purchase. The subscription renews automatically unless it is canceled at least 24 hours before the end of the current period. Manage or cancel it in your Apple Account settings. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://a-gnt.com/page/privacy
