ChatGPT + Claude shared memory
Shared memory for ChatGPT, Claude, Gemini, and more
On their own, ChatGPT and Claude can’t share memory — each keeps its memory locked inside its own app. So switching models means starting over.
Echo gives them one shared memory, so the context you build in ChatGPT is available in Claude and Gemini without re-explaining yourself.
Can ChatGPT and Claude share memory?
On their own, no. ChatGPT’s memory works only inside ChatGPT, and Claude’s memory works only inside Claude. Neither model can see what you told the other. So if you research a topic in ChatGPT and then move to Claude, you start over.
With Echo, they can. Echo keeps one shared memory that both models read from, so the context, decisions, and details you built in ChatGPT show up in Claude — and in Gemini — without copy-pasting or re-explaining.
Why share memory between ChatGPT and Claude?
Most people use these models for different strengths. You might brainstorm in ChatGPT, then move to Claude for long-form reasoning, then check something in Gemini. Each model is good at something — but each one forgets what the others know.
Shared memory lets you use the best model for each task without paying a tax every time you switch. The thread of your work stays continuous even as the underlying model changes.
- Research in one model, write in another — without re-summarizing.
- Keep one project context that every model can read.
- Stop pasting the same brief into ChatGPT, then Claude, then Gemini.
How Echo gives them one memory
Echo runs as a free browser extension. When you capture context in ChatGPT, Claude, or Gemini, Echo stores it in a single shared memory layer and makes it available in the others. One click to save, and it is there the next time you switch.
Because the memory lives in Echo and not inside any one model, adding a tool does not create another silo. ChatGPT, Claude, and Gemini all draw from the same place.
Beyond two models — and into your IDE
Shared memory is not limited to chat. Echo connects to editors and agents like Cursor through MCP, so the context you built in ChatGPT and Claude is also available where you write code. Your research stops being stranded in a chat window.
The same memory spans your chats, your research, and your tools — one continuous context instead of a dozen disconnected ones.
Start sharing memory in one click
Install the free Echo extension, sign in, and it works across ChatGPT, Claude, and Gemini immediately. There is nothing to configure and no API key needed for the browser.
Start free, and upgrade to Pro when you want unlimited memory, image and PDF support, and deep search across every model.
ChatGPT + Claude memory FAQ
Can ChatGPT and Claude share memory?
Not on their own — each keeps memory inside its own app. With Echo they can: Echo holds one shared memory that ChatGPT, Claude, and Gemini all read from, so context built in one model is available in the others.
Does Claude remember what I told ChatGPT?
Not by default. But with Echo, the context you built in ChatGPT is carried into Claude and Gemini, so switching models does not mean starting over.
Do I need separate setups for ChatGPT and Claude?
No. You install Echo once and it connects both models — plus Gemini — to a single shared memory. There is no per-tool configuration.
Is the shared memory free?
Yes. The free plan and the Chrome extension let ChatGPT, Claude, and Gemini share memory at no cost, with Pro available for unlimited memory and deep search.
Can I control what gets shared between models?
Yes. Your memory belongs to you — you can browse, edit, export, and delete it, and decide which context is shared across your tools.
Let ChatGPT and Claude share one memory.
Install the free Echo extension and your context follows you across every model.
