Claude Brain

claude-brain

    Sync your Claude Code brain across machines — portable, automatic, intelligent.

    🇨🇳 中文

    claude-brain is a Claude Code plugin for brain sync — sync Claude Code memory, skills, agents, rules, and settings across all your machines with semantic merge. Cross-machine, portable, zero daily effort.

  Two commands. Zero daily effort. Works forever.

The Problem

You use Claude Code on multiple machines. Your laptop has learned your coding patterns. Your desktop has custom skills. Your cloud VM has different rules. None of them talk to each other.

Every time you switch machines, you lose context. You re-teach Claude the same things. Your carefully crafted CLAUDE.md stays behind.

The Solution

Two commands. Zero daily effort. Works forever.

Why claude-brain?

No other tool does cross-machine semantic merge of Claude Code's brain state.

Key Features

- Auto-sync — hooks run on every session start/end, zero effort
- Semantic merge — LLM-powered deduplication of memory and CLAUDE.md (not just overwrite)
- N-way merge — laptop + desktop + cloud VM all converge intelligently
- Encryption — optional age encryption for brain snapshots at rest
- Team sharing — share skills, agents, and rules with teammates
- Auto-evolve — promotes stable patterns from memory to durable config
- Security-first — secrets stripped, env vars excluded, private repo enforced
- Dirt cheap — ~$0.50-2.00/month typical usage via claude -p

Quick Start

Install

Initialize (first machine)

Join (other machines)

With encryption

Done. Auto-sync handles everything from here.

Commands

What Gets Synced

Architecture

No central server. Git handles transport. Each machine merges on pull.

Merge strategy:
- Structured data (settings, keybindings, MCP) → deterministic JSON deep-merge…
