Croft positions the shared list as distinct from per-account chat memory and per-product project instructions, adding version history showing who changed a note and from which assistant, plus a synced copy of business data from connectors including Xero, Stripe, HubSpot, Pipedrive, Attio, Square and Paddle.

One list on your private Croft server: tell any assistant to remember something and everyone's AI knows it, next to your synced business data and the apps they build on top.\n\n## Quick answer\n\nTo give **Claude and ChatGPT a shared memory for your team**, connect them to\n[Croft](https://oncroft.net/). Tell any assistant **remember for the team: refunds over $500 need\nSam’s approval**. That note lives on your private server. [Claude](https://oncroft.net/connect/claude/),\n[ChatGPT](https://oncroft.net/connect/chatgpt/), [Cursor](https://oncroft.net/connect/cursor/), [Grok](https://oncroft.net/connect/grok/),\nor any MCP assistant connected to the same croft can read it from then on. You\ncan see every change, who made it and from which assistant, and restore an\nearlier version.\n\nThat is half of it. The other half is the tidy copy of your business tools sitting next to that list, so answers use today’s numbers and the apps your AI builds already know what the team means.\n\n## Personal chat memory is not a team memory\n\nPeople already try to make an assistant “remember the business.” The usual places to put that knowledge are a poor fit for a team:\n\n- **Chat memory in one assistant.** Useful for one person. What you tell Claude\nin your account does not show up in a teammate’s ChatGPT, or even in their\nClaude, unless they typed it too.\n- **Project instructions or a custom prompt.** Fine for one product and one\nworkspace inside that product. Another assistant, or a new hire’s account,\nstarts from a blank page. You copy the text by hand and hope the copies\nstay in sync.\n- **A shared doc you paste into every chat.** The file goes stale. Nobody can\nsee which assistant last changed a rule, and nothing is restored if a bad\nedit lands.\n\nDevelopers and everyone else hit the same wall. The facts exist. They are not in one place every assistant can read, next to the live numbers those facts refer to.\n\nRelated: [how to ask Claude about your Xero data](https://oncroft.net/blog/ask-claude-about-your-xero-data/)\nwhen the gap is current books, not only shared rules, and\n[how to get AI to email overdue invoices every Monday](https://oncroft.net/blog/ai-weekly-overdue-invoice-email/)\nwhen you want that shared context to run a job.\n\n## Personal assistant memory vs Croft team memory\n\n| Need | Personal chat memory | Project instructions in one assistant | Croft team memory | \n|---|---|---|---|\n| One list for the whole team | No, it stays with that person | Only inside that product | Yes, on your private server | \n| Claude and ChatGPT see the same notes | You copy them | You copy them | Connect both; they share the list | \n| Cursor, Grok, any MCP assistant | Another paste | Another paste | Same croft, same memory | \n| See who wrote it, and from which assistant | Not as a team log | Not as a team log | Yes | \n| Restore an earlier version | Depends on the product | Depends on the product | Yes | \n| Sits next to current Xero, Stripe, HubSpot | You paste a spreadsheet | You paste a spreadsheet | Synced copy on the same server | \n| Says how fresh the numbers are | No | No | Yes, for example “synced 12 minutes ago” | \n| Then do the work (draft an invoice, Monday email) | Manual | Manual | Your AI builds a small app on Croft | \n| Keys stay off the AI | File still left the tool | File still left the tool | Croft holds the connection | \n\nCroft is not “turn on memory in every chat product you use.” It is one team\nmemory, plus the connected data, on a server that is yours. Setup:\n[Croft for teams](https://oncroft.net/for/teams/), [your data](https://oncroft.net/data/),\n[connectors](https://oncroft.net/connectors/).\n\n## Steps: trial, connect tools, connect AI, remember for the team\n\n1. [Start a free trial](https://app.oncroft.net/signup?plan=team&billing=annual&src=blog) to get a croft, your private server. 7 days, no card.\n2. Connect the tools you already run. [Xero](https://oncroft.net/connectors/xero/) is the usual\nstart for invoices and retainers. Stripe, HubSpot, Pipedrive, Attio, Square,\nPaddle, Google Search Console and others are on[connectors](https://oncroft.net/connectors/) .\nConnecting starts the sync. Croft keeps a tidy copy on your server, named\nlike a spreadsheet:**Sales invoices** ,**Bills** ,**Contacts** . New sources\nare visible to admins until you open them to the team or to named people.\nKeys never reach the AI.\n3. [Connect Claude](https://oncroft.net/connect/claude/) and[ChatGPT](https://oncroft.net/connect/chatgpt/) . Add\nCroft as a connector and connect.[Cursor](https://oncroft.net/connect/cursor/) and[Grok](https://oncroft.net/connect/grok/) use the same kind of link. Developers can point a\ncoding assistant at the same croft. You bring your own AI account. Croft\ndoes not meter tokens.\n4. In any of those chats, say: **remember for the team: refunds over $500 need\nSam’s approval.** Add the words the team actually uses, such as**“retainer” means the monthly fee in Xero item RET-01.** Open another\nassistant and ask about retainers or refunds. It already has the note.\n5. When you want something done, not only remembered, ask for the app:\n**Draft an invoice for Acme’s overdue retainer** , or**Every Monday, email\nme the list of overdue invoices.**\n\nThe connection is MCP, so any assistant that speaks it can use the same croft. Company login sits in front of the croft, so teammates open the data and the apps without a separate login for each tool.\n\n## Equal halves: shared memory plus data, and the apps built on top\n\n**Shared AI memory for a team** only pays off if the assistant also has the\nnumbers those words point at.\n\nOn the memory and data side, Croft keeps one list everyone can see, next to\nthe synced copy of your tools. When someone asks about a retainer, the\nassistant can use the team’s meaning (Xero item RET-01) and the current Sales\ninvoices copy, and say when that copy was last synced. Admins decide who sees\neach source. Browse it yourself on [your data](https://oncroft.net/data/).\n\nOn the apps and automations side, ask your assistant to build the job on that\nsame context. From [automations](https://oncroft.net/automations/):\n\n- It runs on a **schedule or an event** , on your private server.\n- It can **read, summarise and draft** using your own Claude or OpenAI\naccount (your subscription, not a resold one).\n- It can **email, alert or update an app** when it finishes.\n- You build it by **asking in plain words** . There is**no per-automation\nfee** .\n- **Destructive actions ask first** , and**every run is logged** with who\nasked and which AI did it.\n\nThat is the equal half of the product: a shared memory and current data so\nanswers are right for your business, **and** a place that AI can hang the\ninvoice draft or the Monday overdue email on.\n\nTell Claude the retainer rule and ChatGPT can draft from it. Tell ChatGPT that refunds over $500 need Sam, and the refund app Claude builds already knows to ask. See every change, which assistant made it, and restore an earlier version if a note should not have landed.\n\n## FAQ\n\n### How do I give Claude and ChatGPT a shared memory for my team?\n\nConnect them to Croft. Tell either assistant **remember for the team:** and\nthe fact. The entry lives on your private server. Every connected assistant\ncan read it. You can see who wrote it, from which assistant, and restore an\nearlier version. Start from [Croft for teams](https://oncroft.net/for/teams/).\n\n### How do I get shared AI memory for a team?\n\nPut the memory on the team’s server, not in one person’s chat.\n[Connect Claude](https://oncroft.net/connect/claude/), [ChatGPT](https://oncroft.net/connect/chatgpt/),\n[Cursor](https://oncroft.net/connect/cursor/) or [Grok](https://oncroft.net/connect/grok/). They share one list.\n\n### How do I share memory across Claude and ChatGPT?\n\nConnect both to the same croft. A note added in one is visible in the other. You do not copy project instructions between products.\n\n### What is team memory for AI assistants?\n\nA shared list of facts the whole team wants every assistant to know. It sits on your Croft server with a history of changes. It is not one person’s chat memory in a single assistant.\n\n### How do I make Claude remember things for my whole team?\n\nConnect Claude, then say **remember for the team:** and the fact. Teammates’\nother assistants pick it up. Personal Claude memory stays in that person’s\nClaude account.\n\n### Is Croft team memory the same as chat memory in Claude or ChatGPT?\n\nNo. Chat memory and project instructions in an individual assistant usually stay with that person and that product. Croft team memory is one list for the workspace, with a change log and restore.\n\n### Does team memory replace our Xero or Stripe data?\n\nNo. Memory holds the team’s words. Croft also [syncs the tools](https://oncroft.net/connectors/)\ninto a tidy copy. The AI uses both, and says how fresh the data is.\n\n### Can the same shared memory power apps and automations?\n\nYes. Ask it to draft an invoice or to\n[email overdue invoices every Monday](https://oncroft.net/blog/ai-weekly-overdue-invoice-email/).\nThe app runs on Croft, uses the synced copy and team memory, and never sees\nthe keys. Details: [automations](https://oncroft.net/automations/).\n\n### How much does Croft cost?\n\nSolo from $24/month billed annually, Team $99/month billed annually,\nEnterprise custom. 7-day free trial, no card to start.
