prism-coder

Overview

Prism Coder is a comprehensive Model Context Protocol server that creates a 'Mind Palace' for AI agents, enabling persistent memory across sessions. It implements cognitive routing with different memory stores (episodic, semantic, procedural) and supports both cloud and local inference through its own fine-tuned models. The system features semantic search capabilities, proactive session drift detection, and a visual dashboard. Prism operates locally-first with HIPAA-hardened architecture, requiring no API keys for the free tier, and supports both Ollama local models and cloud fallback options.

FAQ

How does Prism Coder handle data privacy?

Prism operates locally-first with HIPAA-hardened architecture. The free tier runs entirely on your machine with SQLite and local embedding models, requiring no API keys or cloud connections. Data never leaves your device unless explicitly synced to the cloud tier.

Can I use Prism Coder offline?

Yes, the free tier runs entirely offline with local models. Prism supports an offline cascade system (14B → 8B → 1.7B) that maintains functionality even without internet access, ensuring critical tools like AAC (Augmentative and Alternative Communication) remain available.
