ctxsync is a Python tool that automates the synchronization of local files with Claude.ai Projects
ctxsync (formerly known as ClaudeSync) bridges your local development environment with Claude.ai projects, enabling seamless synchronization to enhance your AI-powered workflow.
Renamed from ClaudeSync: the
claudesyncPyPI package is deprecated — installctxsyncinstead. Your existing configuration is picked up automatically:~/.claudesyncis migrated on first run and project-local.claudesyncdirectories keep working.
