Configuration

Create .nova/config.json in your project root:

{ "storage": { "mode": "project" }, "features": { "taskManagement": true, "knowledgeGraph": true }, "tools": { "search_patterns": true, "analysis_conflicts": true, "project_profile": true } }

Storage Modes

ModeDescription
projectStore in .nova/memory.db (default)
globalStore in ~/.nova-memory/memory.db
multiQuery across multiple project databases

Multi-Project Configuration

{ "storage": { "mode": "multi", "multiProject": { "enabled": true, "includePaths": ["/projects/api", "/projects/web"] } } }

Storage Location

All data stored locally in SQLite:

  • Project mode: .nova/memory.db in project root
  • Global mode: ~/.nova-memory/memory.db in home directory

No cloud services. No external API calls. No telemetry.
