Go wherever, with all your thinking.
Don't get locked into one AI app.
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.
A short silent animation: in ChatGPT you ask to save a trip plan, and it lands in Your stuff in XOR. Then Claude, Grok and any other AI app each answer a question from that same trip plan, and you open the note yourself in XOR.
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.
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.
Nothing new to learn. Say what you want, in whichever AI app you're in.
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.
XOR is an MCP memory server. Save something in one app and find it in any other.
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.
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.

That night, in ChatGPT
Any new signups?
Two since 6pm: Lin and Sam. Both are on your list.
Your site and tools send things in day or night, and every app can see them.
Paste one prompt into any AI app, and it walks you through the setup.

No plans, no seats. Crazy cheap. See every price.
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.
