core

Your Personal AI OS

Not a chatbot you open. An AI that is always on, always watching. Name it. Shape it. Connect it to everything you use. Reach it however you work. Open source, self-hosted, yours forever.

Watch CORE take a plain-text task, gather context from GitHub and memory, plan the work, run a Claude Code session, and open a PR:

Memory CORE indexes email, meetings, GitHub, Linear, Slack and every assistant conversation into a temporal knowledge graph. Every task starts with the full picture — preferences, decisions, and prior context already loaded.
Tasks Every unit of work is a task with your spec, CORE's plan, live state, and a dedicated chat thread. One-shot or recurring. Each task can spawn a coding session, drive the browser, or run terminal commands.
Scratchpad Your daily page. Write [ ] Fix the auth bug from issue #47 and CORE picks it up within 3 minutes, loads context from your repo and memory, and drafts a plan.
Voice Press Ctrl+Option on Mac and speak. CORE runs the task in the background without breaking your flow — no window to open, no context switch.
Messaging Reach CORE from WhatsApp, Slack, or Telegram. Send a task from the airport or from bed — CORE has the same memory and context regardless of where the message comes from.
Coding agents CORE spins up Claude Code or Codex sessions with the full task context, runs them on your machine or in Docker/Railway, and opens a PR when done. Sessions keep running when your laptop is closed. Point CORE at your existing Claude or Codex subscription — the whole stack runs on it, no separate API key needed.
Browser A built-in browser CORE can drive on your behalf. Because it's isolated from your main browser, you log in only to the accounts you want the assistant to access.
Integrations One-click integrations to 50+ apps via MCP — GitHub, Linear, Jira, Slack, Gmail, Calendar, Sentry, Notion, Todoist. Webhook triggers turn inbound events into proactive work.

CORE can point at your existing Claude Pro or Codex subscription instead of API keys. Memory, planning, task execution, and coding sessions all run on the subscription you already pay for — no per-token bill on top.

Open source and self-hosted. Your data stays in your infrastructure.

Choose your path:

Install and start CORE:

npm install -g @redplanethq/corebrain && corebrain setup

The setup wizard asks for an install directory, AI provider, API key, and chat model. It generates secrets, starts the stack, and opens http://localhost:3033.

Most local installs take a few minutes once Docker is running.

Or deploy on Railway:

Connect a gateway so CORE can run coding agents, drive your browser, and access local folders:

corebrain login
corebrain gateway setup

Requirements: Docker 20.10+, Docker Compose 2.20+, 4 vCPU / 8GB RAM

Full self-hosting guide

Your first task (2 minutes after setup):

1. Open the Scratchpad (your daily page at http://localhost:3033)
2. Type [ ] Summarize my open GitHub issues or any task you would normally do yourself
3. CORE picks it up within 3 minutes, gathers context from connected apps, and drafts a plan
4. Approve the plan and CORE runs it and brings back the result

We are building CORE in public.

We share the roadmap and architectural decisions openly because the hardest problems in building a personal OS are best solved with the people using it. Star the repo, self-host it, share what you build, and open issues for what is broken or missing.
