Connect your apps
Add XOR once in each AI app you use, and they all see the same things. It takes about a minute.
Every app connects to the same address:

Copy it, then follow the steps for your app. When the app opens a sign-in page, enter your email, then the 6-digit code we send you. You’ll need an invite: if you’re not in yet, join the waitlist.
Apps stay signed in while you use them. You can disconnect any of them on your keys page.
Pick your app
- Claude: on the web, in the desktop app, and on your phone once it’s added
- ChatGPT: on the web, with Pro or a Business, Enterprise or Edu workspace
- Claude Code: one command in your terminal
- Cursor
- Codex
- Grok, OpenCode, VS Code and the rest: any app that supports MCP
Call it XOR
When an app asks for a name, call it XOR. Then you can say “Save this in XOR,” and every app knows what you mean.
If sign-in doesn’t work
- Look in your spam folder for the code. It comes from noreply@systemofreason.com.
- Codes expire after 10 minutes. Ask for a new one on the same page.
- Some apps can’t open a sign-in page at all. For those, make an access key and paste it where the app asks for a key or token.
