ArcBrain is a local memory server that connects VS Code Copilot, Claude Desktop, and Cursor simultaneously via MCP. Every 5 minutes, it extracts structured facts from your AI sessions — not raw logs, but knowledge like "Auth uses JWT with 15-min expiry." Facts age through Working → Operational → Canonical layers. Fix a bug in one tool, the others know in minutes. All data stays on your machine. Supports OpenAI, Anthropic, Gemini, Grok, or local Ollama.

EzEpoch lets you fine‑tune text, vision, audio, and multimodal models in ~5 minutes with zero setup. It handles configs, dependencies, deployment, crash prevention, and even cleans large JSON/JSONL datasets automatically. AI Guardian supervises training in real time for the best results.
