What is Claude Mem?

An AI memory archive that captures and organizes your coding sessions automatically

Real-Time Capture

Claude Mem observes your AI coding sessions in real-time, automatically taking notes on decisions, bugfixes, features, and discoveries. Every valuable insight is captured without manual effort.

GitHub

Searchable Archive

All observations are organized by time, type, and semantic concepts. Search by file, concept, or timeframe to find exactly what you need. Before/after context shows causality for each observation.

Documentation

Token Efficient

Progressive disclosure architecture ensures token efficiency. Only load the context you need, when you need it. Perfect for long coding sessions where context management is critical.

Claude Mem Features

Everything you need for persistent AI memory

Automatic Note-Taking

Observes your coding sessions and automatically captures decisions, discoveries, and changes without manual intervention.

Semantic Search

Search observations by file, concept, or semantic meaning. Find related insights across your entire coding history.

Local Storage

All data stays on your machine. Your coding insights and observations never leave your local environment.

Real-Time Sync

Observations are captured and indexed in real-time as you work. No delays, no batch processing.

Context Preservation

Before/after context for each observation shows causality. Understand not just what changed, but why.

Progressive Disclosure

Token-efficient architecture loads only what you need. Perfect for managing context in long sessions.

What Can Claude Mem Do?

Capture and recall insights from your AI coding sessions
