Dual-Layer Intelligence & Privacy:
1. AI-Powered Mind Extension Turn your notes into a living conversation. By opting to store general information in our standard secure cloud, our integrated AI learns from your authorized, unencrypted data to answer questions, summarize long threads, and connect dots you might have missed. It’s not just a database; it’s a personalized co-thinker that understands the context of your life.

2. Absolute End-to-End Encryption (E2EE, 0-knowledge) For your "eyes only" assets—private keys, raw journals, or confidential strategies—ExtMemo offers a fortress. Switch to Sovereign Mode (E2EE) to encrypt data directly on your device. We don’t hold the keys, we don’t see your content, and we don’t want to. Even in the event of a breach, your data remains an unreadable cipher. Total privacy, zero compromise.

Your thoughts are your power. Keep them smart. Keep them sovereign.

### 2.3.6 — 2026-06-25

Introducing a brand-new Visual To-Do module custom-built for agile, fast-moving teams like boutique law firms, creative studios, and close-knit groups. We realized that heavyweight todo manager tools are often too bloated and exhausting to manage. That’s why we built a streamlined, highly visual task architecture that strips away the complexity and lets you focus entirely on execution.

Here are the 4 main things it does:

Smart Order by Due Date: The app automatically counts the "days left" for each task. The most urgent tasks always jump to the very top. Also, the background color changes automatically (like turning red when a deadline is super close) so you know what's burning in 3 seconds.

Easy Drag-and-Drop Lines: No boring tables. It's a visual board where you can just drag a line between Task A and Task B to set up a dependency.

"Days Left" Passing Down: If Task A depends on Task B, Task B will automatically show the time pressure of Task A. This way, the person doing Task B knows exactly how their delay affects the whole project. No more chasing people around.

Clean Project Folders + Context: You can jump into a specific project to see only its tasks without distraction. Plus, the tasks stay right inside your meeting notes or documents, so you never lose the background story of why you need to do it.

### 2.3.3 — 2026-05-29
