Signet

Signet is a memory and context management system designed for AI agents and developers working across multiple AI coding tools and models. It stores memories, preferences, decisions, and evidence in a local, portable format that persists across sessions without requiring cloud accounts. The system automatically converts session transcripts into structured semantic memory through a background process called "dreaming," maintaining an audit trail back to original sources.

Signet integrates with Claude Code, OpenCode, Codex, Gemini CLI, and other AI harnesses, allowing teams and individuals to maintain shared knowledge bases without context fragmentation. It emphasizes inspectability and portability—all memory is readable by design, backed by sources, and can be moved or backed up without permission. The material indicates the project was built using Claude Code.
