hjertefolger-cortex is a Claude Code plugin that adds persistent on-device memory so sessions can recall prior context without cloud storage.
About
hjertefolger-cortex is a Claude Code plugin that adds persistent local memory so your agent can recall context from earlier conversations on the same machine. Developers running long Claude Code sessions often hit the wall when every new chat starts from zero; Cortex targets that friction by keeping recall on disk locally instead of routing memory through a cloud service. It fits anyone shipping with Claude Code who cares about session continuity, offline-friendly workflows, and not shipping proprietary context to third-party memory APIs. You still bring your own project setup and Claude Code install—the plugin extends the agent runtime rather than replacing your stack. Compared with ad-hoc copy-paste of summaries or external note apps, Cortex is meant to live inside the agent loop. Catalog metadata lists one plugin in the bundle and community interest around local, cross-session recall.
- Persistent local memory store—no cloud sync required
- Cross-session recall so multi-day solo builds stay coherent
- Supports longer Claude Code sessions with less re-explaining
- 1-plugin bundle from hjertefolger/cortex
- Memory-category extension aimed at privacy-conscious builders

What it does
Install when you want Claude Code to remember prior context across sessions on your machine without cloud memory services.
Who is it for?
Privacy-minded developers who live in Claude Code for days-long features and want cross-session recall on their own hardware.
Skip if: Skip if you need shared, org-wide memory across machines or mandatory cloud audit trails for compliance.
What you get
After you register the plugin, Claude Code can draw on locally stored memory across sessions so you spend less time re-briefing the agent.
