# OpenBrain Architecture

> A database-first AI memory system that stores raw, structured data at ingest and defers AI synthesis until query time, ensuring high factual provenance and multi-agent scalability.

## Overview

The **OpenBrain Architecture**, developed by [[entity-nate-b-jones]] and instantiated in [[entity-openbrain]], is a structured, database-first approach to AI memory. Unlike the [[concept-ai-wiki]], OpenBrain treats the AI primarily as a *reader* rather than a *writer*.

## How It Works

When new information arrives, the system does **not** attempt to synthesize it into a narrative. Instead, it faithfully stores, tags, categorizes, and indexes the raw data into structured tables. The cognitive heavy lifting is deferred until [[concept-query-time-synthesis]] — when a user asks a question, the AI acts as a librarian (see [[concept-librarian-metaphor]]), searches the pristine database, retrieves the exact relevant files, and generates a fresh synthesis on the fly.

## Properties

- **High provenance**: raw sources are never overwritten or smoothed over.
- **Multi-agent safe**: native concurrency controls handle simultaneous edits from agents like [[entity-cursor-d11]], Claude, ChatGPT, and automated scripts (see [[claim-db-better-multi-agent]] and [[concept-race-conditions-ai]]).
- **Metadata-rich**: enables filters such as *show all notes from Q1 regarding pricing*.
- **Audit-ready**: ideal for corporate environments where factual accuracy and traceability matter.
- **Stores [[concept-silent-contradictions]] safely**: contradictions sit side-by-side rather than being resolved by an AI editor.

## Trade-offs

OpenBrain lacks the immediate, readable narrative synthesis of a wiki. Synthesis must be performed at query time, which costs more compute and latency per request. The optimal solution combines the two via [[concept-hybrid-memory-architecture]].
