CORE: Your Digital Brain

It Remembers. It Thinks. It Acts

CORE is your digital brain—an integrated, always-on AI that remembers your context, collaborates with your AI agents, and operates across your tools.

Open source. Self-hosted. Your data, your control.

What Defines a Digital Brain

It Remembers Everything

Every conversation, decision, preference, and relationship is stored as structured knowledge in a temporal knowledge graph. Not raw text, but classified facts (preferences, decisions, goals, directives) that appear precisely when you need them. Ask about something from weeks ago and the answer is there, with full context.

It Can Take Actions

Create GitHub issues, send Slack messages, manage your calendar without leaving the conversation. Complex multi-step workflows too: ask your coding agent to check Sentry for new errors, create a GitHub issue for each one, assign the right engineer based on git blame, and post a summary to your team's Slack channel, all from a single prompt. 200+ actions across 50+ apps through one connection point.

It Thinks and Works Across Systems

Your tools are siloed. Claude Code can't talk to your WhatsApp. Cursor can't check your calendar. CORE's Agent breaks these walls - it's the orchestrator that ties memory, toolkit, and your apps together.

What the CORE Agent can do:

Understand intent: classifies what you need and routes to the right tools and memory
Spawn other agents: spin up a Claude Code session or browser session from WhatsApp to fix a bug or research something
Coordinate multi-step workflows: pull context from memory, act across multiple apps, and report back
Work from anywhere: message from WhatsApp, email, Slack, or the web dashboard — same brain, same context

It Can Proactively Act

You shouldn't have to ask for everything. CORE monitors events - new emails, GitHub alerts, calendar changes — and evaluates them against what it knows about you. A client email arrives; CORE already knows how you handle that relationship and drafts the right response. A Sentry alert fires at night; CORE spins up a Claude Code session to investigate.

Architecture

CORE is built on three layers that implement these four pillars:

Memory: A temporal knowledge graph that stores episodes, entities, and classified facts. Every piece of information is categorized (preference, decision, directive, goal, etc.) and connected over time. This is what makes retrieval intent-driven instead of keyword-based. Docs →

Toolkit: A unified actions layer for any MCP-compatible agent. Connect your apps once (GitHub, Linear, Slack, Gmail, Calendar, etc.) and every connected AI tool gets access to 200+ actions through a single endpoint. Docs →

CORE Agent: The orchestrator that ties memory and toolkit together. It understands intent, searches memory, picks tools, spawns other agents, and can act proactively based on triggers and rules. Docs →

What You Can Do

Use as Your Personal Assistant

Talk to CORE from WhatsApp, email, or the web dashboard. It takes actions across your apps, manages your schedule, drafts emails, all with memory of who you are and how you work.

Supercharge Your AI Agents

Give Claude Code, Cursor, and other AI tools persistent memory and actions. Your coding agent remembers project architecture, past decisions, and preferences across sessions. No more re-explaining context.

Get started →

Claude Code (Recommended: Plugin)

npm install -g @redplanethq/corebrain

Then in Claude Code:

/plugin marketplace add redplanethq/core
/plugin install core_brain

Restart Claude Code and run /mcp to authenticate.

The plugin auto-loads your persona (preferences, rules, decisions) at every session start and ingests conversations into memory when you're done.

Claude Code (Manual MCP)

claude mcp add --transport http --scope user core-memory https://app.getcore.me/api/v1/mcp?source=Claude-Code

Then type /mcp and open core-memory for authentication.

Cursor

OpenClaw

openclaw plugins install @redplanethq/openclaw-corebrain

Set your API key via environment variable or config:

export CORE_API_KEY=your_api_key_here

Get your API key from app.getcore.me → Settings → API Key.

Claude Desktop

Copy MCP URL: https://app.getcore.me/api/v1/mcp?source=Claude
Go to Settings → Connectors → Add custom connector
Click "Connect" and grant Claude permission to access CORE

30+ more providers — Windsurf, VS Code, Cline, Codex, Gemini CLI, Copilot, and more. See all setup guides →

Turn AI Chats into Memory

Sync your ChatGPT and Gemini conversations into CORE via browser extension. Searchable, reusable, and available to every connected agent.

Get started →

Quick Start

Cloud

Sign up at app.getcore.me
Connect Gmail & Calendar — CORE scans them to learn about you so your digital brain starts with real context from day one
Start using — talk to CORE Agent, connect your AI tools, or take actions in your apps

Self-Host

Quick Deploy

Or with Docker

git clone https://github.com/RedPlanetHQ/core.git
cd core
Configure OPENAI_API_KEY in core/.env
docker-compose up -d

For Agent Builders

Building AI agents? Offload memory and integrations to CORE so you can focus on your agent's logic.

Offload memory — Use CORE's temporal knowledge graph as your agent's long-term memory. Store conversations, retrieve context with intent-driven search, and let your agent build knowledge over time without managing your own vector DB or graph.
Offload integrations — Connect apps once in CORE, and your agent gets MCP tools for all of them. No OAuth flows to build, no API maintenance, no per-integration code.
Build via MCP or API — Connect your agent to CORE via MCP (single endpoint) or use the REST API directly.
