Private Memory
Build a private AI memory that learns your preferences, vocabulary, and context. It's not just a database; it's a secure personal AI tailored to your life.
Contextual Learning
The more you capture, the better HyNote understands your personal knowledge context and workflows. It learns your vocabulary—when you say "the client," it knows you mean Acme Corporation. It recognizes your writing style and suggests completions that sound like you. It remembers your preferences and applies them automatically. This learning happens privately in your account. We don't use your data to train general AI models. Your personal context stays strictly yours, making HyNote more useful over time while maintaining complete privacy. Get answers that sound like you and align with your past research. When you ask about a topic, HyNote considers your previous captures, preferred sources, and established viewpoints.
Privacy-First Encryption
Your digital memory is secured with end-to-end encryption, ensuring your private data stays private. Data is encrypted on your device before transmission using AES-256. It remains encrypted in transit (TLS 1.3) and at rest on our servers. Optional client-side encryption means only you hold the decryption keys—even we can't access your content. Zero-knowledge architecture options available for enterprise customers. Your encryption keys can be stored in your own infrastructure, giving you complete control. We can't decrypt your data even if compelled. This is privacy by design, not privacy as an afterthought.
Long-term Recall
Instantly retrieve facts or ideas from years ago with AI-powered memory retrieval that goes beyond keywords. Your digital memory grows more valuable over time as patterns emerge and connections form. That insight from 2019 becomes relevant to your 2024 project, and HyNote surfaces the connection. Search across decades of captures in milliseconds. Semantic search finds concepts even when you don't remember exact words. Version history preserves how your thinking evolved. Long-term storage with no expiration. Export your complete memory anytime—your data is always portable.
Personalized AI Response
Get answers that sound like you and align with your past research and preferences. Response customization includes: preferred detail level, writing style matching, citation of your own notes, and awareness of your current projects and priorities. The AI assistant truly becomes yours over time. It doesn't give generic answers—it gives your answers, grounded in your knowledge base. When you ask about a topic, HyNote considers your previous captures, preferred sources, and established viewpoints. This is the difference between a generic AI and your personal AI memory.
