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. Instead of switching between different AI apps, assistants, and workflows, LegaCAE creates a continuous cognitive layer that can connect multiple models, local and cloud AI providers, personal knowledge, automation systems, and external tools through one interface. 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.

SEE LESS. READ MORE. Mejl is a Gmail client that splits your inbox into focused views. Open the one that matters now, read without the rest of your inbox in the way, and bring it back to zero. READ WHAT MATTERS NOW Give work, travel, newsletters, receipts, and anything else a view of its own. Everything else waits until you're ready for it. GET THROUGH UNREAD, ONE MESSAGE AT A TIME Read, reply, forward, or file each message, then move to the next until the view is clear. LET NEW MAIL FIND ITS PLACE Describe a view in a sentence and Mejl moves matching mail into it. Want exact control? Add a rule instead. Receipts go straight to Receipts. Newsletters wait in Newsletters. Your views stay tidy without another system to look after. ALL THE EVERYDAY STUFF Search, write and send, mark as read or unread, move mail between views, unsubscribe, block senders, and get notified when something new arrives. YOUR MAIL STAYS IN GMAIL Sign in with the Gmail or Google Workspace account you already use. Your messages, labels, and filters stay in Gmail, so there's nothing to migrate. FREE TO USE, PLUS IF YOU WANT MORE Focused views and Gmail filter rules are free, with no trial or time limit. Free includes sorting by description for 10 emails a day. Mejl Plus removes that limit and adds thread summaries, writing tools, and reply suggestions. PRIVACY, STATED PLAINLY Mejl doesn't sell your data or use your messages for advertising. AI features run with zero data retention, and your mail is never used to train models. Obvious tracking pixels are removed before you open a message, and you can delete your Mejl account from Settings at any time.

Verdict
The clearest difference is in-app purchases: Mejl at none against LegaCAE's 5. LegaCAE's advantage is device support (3 vs 1). On price, update cadence, ads and iOS requirement there is nothing between them.
