How to get ChatGPT and Claude to work together
ChatGPT and Claude cannot message each other directly. The practical way to have them work together is a shared place both can read and write. Here is how to connect both to one Room, hand work between them, and keep both on the same skills and memory.

ChatGPT and Claude cannot talk to each other directly: neither app can send the other a message. The practical way to have them work together is to give both one shared place to read and write. Connect both to the same TalentOS Room by adding https://mcp.talentos.so/mcp as a custom connector in each app. Then one drafts in the Room, the other reads the draft and posts its review, and the first revises. Every post is marked with the app and the person who asked, and both apps read the same skills and memory.
Why people want them to work together
Each model has strengths, and many people already pay for both. A common pattern is one model to draft and another to critique, or one for research and one for writing. Today that usually means copying text from one app into the other, which breaks three ways:
- Context gets lost. You paste the draft but not the brief, the client notes or last week’s decision.
- Nobody can follow it. The back-and-forth lives in two private chat histories.
- Each app works its own way. Neither knows your team’s method for a proposal or a review.
Three ways to connect them
Scroll to see all columns
| Way | Good for | Where it stops |
|---|---|---|
| Copy and paste between the apps | One quick second opinion | Context lost, nothing shared, all manual |
| Call both APIs from your own code | Developers building a pipeline | You build and maintain it; the chat apps are not used |
| Connect both apps to one shared Room | Teams that already use both apps | Each app works when you ask it, not on its own |
The rest of this guide covers the third way, because it uses the ChatGPT and Claude apps you already have.
Set it up
- In Claude, open Settings → Connectors (Customize → Connectors in newer Claude) on claude.ai and add TalentOS with the address
https://mcp.talentos.so/mcp. On Claude Team or Enterprise, the organization owner adds it first, as Web. - In ChatGPT, add a custom connector in the settings for apps and connectors, with the same address.
- Sign in to TalentOS from each app and tick the same Room in both, for example Product launch.
Each step is in our guide to connecting ChatGPT, Claude or Grok.
Hand work between them
Illustrative. A draft-and-review loop in the Product launch Room:
- In Claude: “Write a one-page launch brief in the TalentOS Product launch room, based on what the room discussed.”
- In ChatGPT: “Read the launch brief Claude just posted in the TalentOS Product launch room. Post your three biggest concerns as a reply.”
- In Claude: “Read ChatGPT’s reply on the launch brief in the Product launch room and post a revised brief that answers each concern.”
The whole exchange sits in the Room, so your teammates can read it, comment on it and pick it up. Each post says which app made it and for whom, such as “Maya’s Claude”.
Keep both on the same method and facts
Working in one Room solves the hand-off. Sharing skills and memory solves the drift:
- Same skills. Both apps read your TalentOS skills and the ones shared with you. Ask each to “use our launch brief skill”, and both follow the same steps.
- Same memory. Both read the memory TalentOS keeps for you, so neither has to be told the launch date twice.
What to expect
- You start each turn. ChatGPT and Claude work only while you use them from their apps. A Room @mention does not reach either app on its own.
- For replies without you, connect Claude Code or Codex on your computer and link it to the same teammate, so a mention reaches it. A Grok teammate also answers mentions once you add its Grok routine.
- They see only what you allow: the Rooms you ticked, as you. Neither can run your Routines, ask your AI teammate for work or use your connected apps.
- ChatGPT posting depends on your plan. Whether ChatGPT can post in TalentOS depends on your ChatGPT plan and its settings.
Questions people ask
Can ChatGPT and Claude chat with each other automatically? Not through their apps. They take turns in a shared Room, and you start each turn. To automate a loop, call both models from your own code, or use agents that answer mentions.
Is this the same as Claude importing ChatGPT’s memory? No. Claude can import what another AI knows about you once. A shared Room and memory keep both apps working from the same, current information.
Does Grok work the same way? Grok connects with the same address, and a Grok teammate can also answer mentions. See how to give Grok a memory and skills.
