What is Cortex for Claude Code?

Cortex is a Claude Code plugin that gives Claude persistent, self-evolving memory across sessions. It automatically extracts durable lessons (decisions, conventions, bug fixes) from your completed sessions, storing them in a local Obsidian vault.

How does Cortex enhance Claude Code sessions?

Cortex prevents you from re-explaining your project repeatedly. It provides query-tailored context briefings at the start of new sessions, feeding Claude relevant memories so it can start with full context and accelerate your workflow.

Where does Cortex store my memories?

Cortex stores all your durable memories locally in an Obsidian vault as human-readable markdown files. This local-first approach ensures no cloud services, API keys, or vendor lock-in, giving you full control over your data.

Does Cortex offer security features?

Yes, Cortex includes integrated security scanning. Every memory extracted and prepared for storage is checked for potential prompt injection and credential exfiltration before being written to your Obsidian vault.

Provides Claude Code with persistent, self-evolving memory, storing durable lessons in a local Obsidian vault.

Cortex is a Claude Code plugin engineered to equip your AI assistant with persistent, self-evolving memory across sessions. It intelligently minimizes redundant explanations by automatically extracting crucial lessons—such as architectural decisions, coding conventions, and bug fixes—from your completed Claude Code interactions. These insights are securely stored as human-readable markdown files within a local Obsidian vault, ensuring data privacy and local-first operation. When initiating a new session, Cortex synthesizes a query-tailored briefing, presenting only the most relevant memories to Claude, thereby enabling it to start with immediate and comprehensive context, continually learning and adapting as your projects evolve.
