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.
