Keep track of leads. Ada wants a demo, Grace asked about pricing.
Saved both to your leads list.
Later, in Grok
Who wanted a demo?
Ada. She's on your leads list.
Help AI remember.
Save something in one app and find it in any other.
Go wherever.
Do whatever.
All your thinking, in one place every AI app can use. The notes, plans, lists, files and data you build up with AI should belong to you, not stay locked inside one app. Keep them in XOR and take them anywhere you want. Nothing to copy. Nothing to paste.
Don't leave all your thinking in one AI app.
Every chat leaves thinking behind: plans, research, decisions, lists. Today it stays in the app where you made it. Switching means digging out markdown files, pasting them into the next chat and explaining it all again.
With XOR, it's just there.
Your thinking lives in XOR, not in any one app. Connect it once in each app you use, and they all see the same things.
Just ask.
Nothing to set up and nothing new to learn. Say what you want, in whichever AI app you're in.
Every weekday at 9, email me a summary of new leads.
Done. It runs every weekday at 9.
Next week, in Claude
Move my leads summary to 8.
Done. It goes out at 8 now.
Schedule work.
Jobs run in XOR, not inside one app. Start one in ChatGPT, change it from Claude.
Give me a link my signup form can send to. Add each signup to my leads.

Any new signups?
Two since 6pm: Lin and Sam. Both are on your list.

The fine printFor the technically curious
One remote MCP server with OAuth sign-in, for any assistant that speaks MCP. Scoped access keys with spending caps for your own code, and a web API at /v1 that mirrors every tool. Key-value stores, SQL databases and versioned file spaces, each with a purpose note so the next assistant knows what it's for. Seven-day undo on everything, down to a dropped table. Secrets sealed at rest and filled in at request time, never shown to the model. Schedules, signed webhook inboxes, and background agents running Claude with per-run and monthly budgets. Model calls with zero data retention. Prepaid, metered per call, and charged once even when we retry.
