The only note app where AI gets smarter the longer you use it
Novyx Vault is an open-source, local-first personal knowledge base with AI memory that evolves alongside your thinking. Write in markdown, link ideas with wiki-style connections, and let AI surface relationships you never knew existed.
Your notes stay on your machine. Your AI remembers everything — across every conversation, every session, every idea.
Everything you need to build a second brain
Novyx Vault combines the power of AI with the simplicity of plain markdown files. No bloat, no lock-in — just the tools that matter.
Persistent AI Memory
Unlike other AI note apps, Novyx Vault remembers your preferences, projects, and thinking patterns across every conversation. The more you use it, the more useful it becomes.
Local-First Privacy
Your notes live as plain markdown files on your machine. No data leaves your device unless you choose cloud sync. No vendor lock-in, no proprietary formats, ever.
Markdown Native
A powerful CodeMirror-based editor with live preview, wiki-links, backlinks, syntax highlighting, and a full toolbar. Write naturally in markdown with real-time rendering.
Ghost Connections
AI automatically discovers hidden relationships between your notes — even without shared keywords or explicit links. Surface connections you never knew existed.
Knowledge Graph
Visualize your entire vault as an interactive, force-directed graph. See how your ideas connect and navigate your knowledge visually.
Cloud Sync
Optionally sync with Supabase-powered cloud storage for cross-device access. Row-level security ensures only you can see your notes.
How it works
Write and link
Create notes in markdown. Use [[wiki-links]] to connect ideas. Organize with folders, tags, and daily notes.
AI connects the dots
Ghost Connections surfaces related notes automatically. AI chat helps you summarize, brainstorm, and explore your knowledge with full vault context.
Memory grows with you
Every note you save to memory makes your AI smarter. Cortex Insights reveals emerging themes. Entity extraction builds a semantic knowledge graph over time.
AI memory that actually persists
Most AI assistants forget everything between sessions. Novyx Vault is built on the Novyx SDK, giving your AI a real, evolving memory that grows with your knowledge base.
Memory Rollback
Made a mistake? Travel back through your AI's memory timeline. Undo accidental context, restore previous states, and see exactly how your AI's understanding has evolved.
Cortex Insights
As your vault grows, AI generates emerging themes and patterns from your accumulated knowledge. Discover connections between projects, ideas, and research you hadn't noticed.
Entity Extraction
People, projects, concepts, and relationships are automatically extracted from your notes to build a growing semantic graph — a structured map of everything you know.
Bring your own AI
Novyx Vault works with the AI provider you already use. Connect your own API key and choose from over a dozen providers. Your keys stay in your browser — they never touch our servers.
Why Novyx Vault?
