Beautiful Brain

A living memory graph your agents consult before they act — and grow after.

The idea

Useful intelligence is cumulative. Memory should be inspectable, portable, and yours.

What it remembers

01

A graph, not a pile

Memories carry typed edges — caused_by, contradicts, learned_from, depends_on — so recall follows the shape of how decisions actually happened.

02

Multimodal recall

Text, images, audio, and PDFs share one vector space via gemini-embedding-2. A written cue finds the sketch; spreading activation surfaces the context around it, not just the match.

03

Lessons that change behavior

A lesson is structured, not sentimental: the trigger to watch for, the wrong default, the better next action, and the evidence. Agents replay them before repeating a mistake.

04

Cognitive Pulse

A background maintenance runner that notices stale tasks, orphans, and duplicates — then proposes. Review and application stay explicit; your history is never quietly rewritten.

Agent first

Install the skill, add the server, and start every relevant task by asking the graph what it already knows.

# 1. Install the agent skill
mkdir -p "${CODEX_HOME:-$HOME/.codex}/skills/beautiful-brain"
curl -fsSL https://turbo-brain.com/skills/beautiful-brain/SKILL.md \
  -o "${CODEX_HOME:-$HOME/.codex}/skills/beautiful-brain/SKILL.md"

# 2. Connect the MCP server
claude mcp add --transport http beautiful-brain https://turbo-brain.com/mcp

# 3. First use
Call reflect({ topic: "<project>", goal: "<what you are doing>" })
For repeat work: find_process_patterns({ task: "<task>" })

Self-host with your agent

Want your own instance? Hand the setup to your agent: it fetches the self-host skill and drives the whole install — prerequisites, Docker, config, verification — asking you at most three questions.
