不用数据库也不用云服务，就一个文件，能 git 提交也能发给队友。

The Problem

You: "Remember that auth bug we fixed?"
Claude: "I don't have memory of previous conversations."
You: "We spent 3 hours on it yesterday"
Claude: "I'd be happy to help debug from scratch!"

200K context window. Zero memory between sessions.

You’re paying for a goldfish with a PhD.

The Fix

You: "What did we decide about auth?"
Claude: "We chose JWT over sessions for your microservices.
        The refresh token issue - here's exactly what we fixed..."

One file. Claude remembers everything.

Installation

# One-time setup (if you haven't used GitHub plugins before)
git config --global url."https://github.com/".insteadOf "[email protected]:"

# In Claude Code
/plugin add marketplace memvid/claude-brain

Then: /plugins → Installed → mind Enable Plugin → Restart.

Done.

How it Works

After install, Claude’s memory lives in one file:

your-project/
└── .claude/
    └── mind.mv2   # Claude's brain. That's it.

No database. No cloud. No API keys.

What gets captured:

• Session context, decisions, bugs, solutions
• Auto-injected at session start
• Searchable anytime

Why one file?

• git commit → version control Claude’s brain
• scp → transfer anywhere
• Send to teammate → instant onboarding

Commands

In Claude Code:

/mind stats                       # memory statistics
/mind search "authentication"     # find past context
/mind ask "why did we choose X?"  # ask your memory
/mind recent                      # what happened lately

Or just ask naturally: “mind stats”, “search my memory for auth bugs”, etc.

CLI (Optional)

For power users who want direct access to their memory file:

npm install -g memvid-cli

memvid stats .claude/mind.mv2           # view memory stats
memvid find .claude/mind.mv2 "auth"     # search memories
memvid ask .claude/mind.mv2 "why JWT?"  # ask questions
memvid timeline .claude/mind.mv2        # view timeline
