The first public release of TideMind, a living second brain that connects your AI tools, notes, and thinking through a shared memory layer.

Highlights

Core System

• Active Graph — a knowledge graph where memories carry 4D maturity (activity, refinement, connectivity, independence), enabling automatic decay, reinforcement, and crystallization
• Three cognitive tools via MCP protocol: brain_prepare, brain_recall, brain_digest
• Metabolism engine — daily decay cycles, weekly divergent scanning, and crystal emergence

Integrations

• AI Agents: Claude Code, Cursor, Windsurf, Codex, and any MCP-compatible tool
• Note Systems: Logseq (file watching + incremental sync), Obsidian (vault import + Canvas), Apple Notes (read-only sync)

Desktop Client

• Electron-based client for graph browsing, metabolism monitoring, and parameter tuning
• One-click setup for AI tool and note system connections

Data Ownership

• All data stored locally in a single SQLite file
• Full Markdown export
• Flexible model choice: fully local (Ollama), fully cloud (Anthropic/Gemini), or hybrid

Requirements

• Node.js >= 18
• Optional: LLM provider (Anthropic, Vertex AI, Gemini) for information extraction
• Optional: Embedding provider (Ollama, Vertex AI, Gemini) for semantic search
