# StudioMeyer Memory

> Long-term AI memory with bi-temporal knowledge graph. Provider-agnostic memory backend that works with Claude, GPT, Gemini, or any LLM speaking MCP. 56 tools, multi-tenant on Supabase Frankfurt (EU), DSGVO-compliant.

## What this server does

Persists memories that survive across conversations, sessions, and AI clients. Stores learnings, decisions, sessions, skills, and a knowledge graph of entities + observations + relations. Search uses trigram + full-text + temporal decay. Bi-temporal model supports time-travel queries (what did we know on date X?).

## Provider-agnostic

Works with any LLM client that speaks MCP. We tested with Claude (Anthropic), GPT-5 (OpenAI), Gemini (Google), Mistral, Llama, and Ollama-hosted local models. Memory is the storage layer — you bring your own LLM. No vendor lock-in.
