Custom instructions become the brief
What you told ChatGPT about your business becomes a CLAUDE.md brief: short, specific, and editable by your own team, like a good checklist.
Move your company from ChatGPT to Claude.
You spent months teaching ChatGPT how your business works, and that work carries over. We capture it, rebuild it, and pilot it on your live work before you rely on it.
What transfers.
Projects and knowledge, rebuilt per workstream
Each ChatGPT project becomes a workstream directory with its own brief and files, so the rules for quoting never bleed into marketing copy.
Old chats, mined then archived
We extract the decisions and standing rules buried in your chat history. The history itself gets archived.
Memory, written down where you can read it
What ChatGPT remembered about you gets extracted into the brief, where you can see it, correct it, and keep it current.
What does not transfer
Custom GPTs and plugins, as-is. Equivalents get rebuilt where they earn their keep, and we tell you when one does not.
How the move runs.
Export
You export your ChatGPT data from your own account. Your credentials stay yours; we work from the export. That is a standing rule on every engagement.
Extraction
We pull instructions, project knowledge, memory, and the standing rules hidden in your chats into a migration tracker you can inspect line by line.
Rebuild
We scaffold a Claude environment to our standard: one brief per workstream, role assistants where they fit, and your tools connected.
Pilot on live work
Three to five live tasks run against the new setup before you rely on it. Where it binds, we fix it there, and the fix goes in the brief.

One common move, not the only one.
NFCG is model-neutral. We work across Anthropic Claude, OpenAI ChatGPT, Google Gemini, Microsoft Copilot, and Perplexity, and plenty of teams keep more than one. This page covers a single move, ChatGPT to Claude. If staying put or running both fits your work better, we will say so.
Common questions.
Do we lose what we taught ChatGPT?
No. Instructions, project knowledge, and memory get captured from your export and rebuilt as briefs you can read and edit. What cannot transfer as-is, like custom GPTs, gets rebuilt where it earns its keep, and we tell you when one does not.
Do you need our ChatGPT login?
No. You export from your own account and we work from the export. Your credentials stay on your machines, and that rule holds on every engagement.
How long does a migration take?
It scopes like a small project: an export session, extraction, the rebuild, then a pilot on live work. The timeline and the price are set in the written scope, once we have seen what you have.
Can part of the company stay on ChatGPT during the move?
Yes. The pilot runs alongside what you have today, and nothing gets shut off until the new setup is carrying the load.
