AI LLM RAG

Self-hosted Agentic Memory System for LLMs

Published Mar 02, 2026

🔴 Problem Identified

Current RAG (Retrieval Augmented Generation) systems blindly inject retrieved information into every LLM prompt, wasting context window space and reducing efficiency. Developers and AI enthusiasts running local LLMs lack a way to give their models permanent, searchable memory without relying on cloud services or complex database setups.

💡 Proposed Solution

A lightweight FastAPI proxy that sits between chat UIs and LLM backends, providing on-demand RAG via tool calling (LLM decides when to search) and infinite auto-memory with /save commands. Users can give their local LLMs permanent memory by simply pointing their chat UI to the proxy instead of directly to their LLM backend.
