Sonn
Stop repeat mistakes with local reasoning and memory for coding agents
Sonn gives AI coding agents a local-first reasoning and memory layer built for Claude Code. It records sessions, reasons over past decisions, and provides guidance before you ask so settled choices stay settled. Whisper Behavior learns how you work and shapes how the agent acts, not just what it knows; Angel Reasoning reads the pattern and gives the right guidance at the right moment. Your database lives on your machine, generation uses your credentials, and no source code goes to Sonn's servers.
