Quick Start
The fastest path from zero to a working knowledge graph.
Sign in
Visit cortex-nine-bice.vercel.app and sign in with GitHub.
Open the Workspace
Click Workspace in the sidebar. This is where you create and manage notes.
Create a note
Click New Note and fill in:
- Title: A declarative statement (e.g., “Spaced repetition beats cramming for long-term retention”)
- Type:
fact,insight,decision,experience,belief,code_finding, orsynthesis - Content: One atomic idea, written in your own words
- Tags: Comma-separated labels for categorization
- Importance: 0.0 (trivial) to 1.0 (critical)
Follow the Zettelkasten rules: one idea per note, write in your own words, and use a declarative title (not a topic). If your note needs the word “and”, split it into two notes.
Ask a question
Navigate to the AI Assistant and ask a question about your knowledge:
“What do I know about memory and learning?”
Cortex will search your knowledge graph semantically and generate an answer grounded in your own notes.
Watch the activity feed
The sidebar shows real-time cognitive events — note creation, auto-linking, recall queries, and model usage.
What Just Happened?
When you created that note, Cortex:
- Stored it in your personal SQLite database
- Embedded it using sentence-transformers for semantic search
- Scanned for links — if any existing notes are semantically similar, they’re automatically linked
- Indexed it for full-text search via FTS5
- Emitted an activity event via Server-Sent Events to your dashboard
Your knowledge graph is alive. Every note you add makes it smarter.
