LegaCAE One intelligence. Every model. Continuous memory. LegaCAE (Cognitive Autonomous Engineering) is an AI operating system designed to unify conversations, tools, memory, and reasoning into a single persistent intelligence experience.

Features • Multi-model AI access from a single conversation • Support for cloud and local AI providers • Continuous memory and contextual awareness • Real-time streaming responses • Cognitive Autonomous Engineering (CAE) insights and pattern detection • Personal knowledge capture and Codex management • Tool and MCP integration for expanded capabilities • Cross-device continuity designed for a persistent AI experience • Privacy-first architecture with support for user-controlled AI infrastructure Built Around CAE Cognitive Autonomous Engineering is the practice of continuously improving understanding, decisions, systems, and workflows through feedback, memory, and verification. LegaCAE helps transform isolated conversations into connected intelligence by tracking patterns, preserving context, and creating continuity across time. Designed for Builders Whether you’re creating software, researching ideas, managing projects, documenting knowledge, or building your own AI ecosystem, LegaCAE provides a unified workspace where intelligence becomes persistent rather than temporary. The Vision What if every AI model, device, application, and service felt like the same intelligence? LegaCAE is built to explore that future.
Jade Email

Giving out your email address shouldn’t be permanent permission to reach you. Jade lets you use a different address for each company or service on a domain you own. The address you give Netflix is separate from the one you give your dentist. If one starts receiving mail you no longer want, you can cut it off without disturbing the others. When mail first arrives at an address, it appears as an inbox in your account. You decide how new mail is handled in each one. Jade can file a receipt automatically, mark a newsletter read, attempt to unsubscribe from unwanted marketing, or delete a message on the schedule you choose. Reuse the same rules wherever they make sense. Categories can collect receipts from every store or travel details from every booking, even though the messages arrived at different addresses. When Jade finds a verification code or package-tracking number, it puts it above the message, ready to copy or open. Connect an AI assistant through MCP and ask it to find mail, summarize what you missed, organize messages, change rules, or send a reply.
