Brain: Agentic Memory as a Knowledge Wiki
Aug 19, 2026Perplexity Engineering

Summary
This post details the 'Brain' component of Computer's memory system, describing its organization as a filesystem-native knowledge wiki with linked Markdown files. It explains how Brain connects entities and concepts (wikilinks) and links claims to sources (cite references), and how agents explore this memory through a self-directed loop using familiar filesystem operations. It also addresses the challenge of file materialization for efficient agent access.
