Cross-platform AI memory
Cross-platform AI memory for ChatGPT, Claude, Gemini, and Cursor
Cross-platform AI memory is a single memory layer shared across every AI tool you use, instead of a separate memory trapped inside each one.
Echo lets you save context once and reuse it across ChatGPT, Claude, Gemini, and Cursor — so switching tools never resets what your AI knows.
What is cross-platform AI memory?
Cross-platform AI memory is a single memory layer that works across every AI tool you use, instead of a separate memory trapped inside each one. The context you build in ChatGPT is available in Claude. What you told Gemini shows up in Cursor. There is one memory, and every tool reads from it.
This is different from the built-in memory each vendor ships. Those are single-platform by design: useful inside one app, invisible to the rest. Cross-platform memory treats your context as something that belongs to you and follows you wherever you work.
Why one memory across platforms matters
Most people no longer live in a single AI tool. You might draft in ChatGPT, reason in Claude, search in Gemini, and code in Cursor. Each switch resets your context, so you spend the first few minutes of every conversation rebuilding what the last tool already knew.
A cross-platform memory ends that reset. The model you just opened already has the project background, the decisions, and the details. You move between tools the way you move between tabs — without losing your place.
- ChatGPT — carry briefs, prompts, and project context in and out.
- Claude — pick up the reasoning thread without re-summarizing.
- Gemini — keep the same context when you switch to search or research.
- Cursor and IDEs — bring your chat research into the editor through MCP.
How Echo syncs memory across platforms
Echo holds your memory in one place and connects to each tool through a free browser extension. When you capture context in any supported chat, Echo stores it and makes it available to the others — no manual copy-paste, no per-tool setup.
Because the memory lives in Echo rather than inside any single platform, adding a new tool does not fragment your context. It just plugs into the same memory you already have.
Consistent, current, and private
Cross-platform only helps if the memory stays consistent. Echo keeps one source of truth, so an update you make in one tool is reflected everywhere, and you never end up with three slightly different versions of the same context.
And because this is your context, you stay in control: browse it, edit it, export it, or delete it whenever you want. Cross-platform does not mean handing your memory to every platform — it means you keep one memory and decide where it goes.
Get started in one click
There is nothing to configure. Install the free Echo extension, sign in, and your memory starts working across ChatGPT, Claude, and Gemini right away. Connect your IDE and agents through MCP when you are ready.
Start free, and upgrade to Pro when you want unlimited memory, deep search, and Echo working on your behalf across every platform.
Cross-platform AI memory FAQ
What is cross-platform AI memory?
Cross-platform AI memory is one memory layer shared across multiple AI tools — like ChatGPT, Claude, Gemini, and Cursor — so your context is available everywhere instead of being trapped in a single app.
Which AI tools does Echo work across?
Echo works across ChatGPT, Claude, and Gemini in the browser today, and connects to IDEs and agents like Cursor through MCP. It supports additional AI tools as well.
How is this different from ChatGPT or Claude memory?
Built-in memory is single-platform: ChatGPT memory only works in ChatGPT, Claude memory only in Claude. Echo is cross-platform, holding one memory that every connected tool can read from.
Do I have to set up memory in each tool separately?
No. You install Echo once and it connects your tools to a single shared memory. Adding a new tool plugs into the memory you already have instead of creating another silo.
Is cross-platform AI memory secure?
Your memory belongs to you. You can browse, edit, export, and delete it at any time, and you control which context is shared across your tools.
One memory across every AI platform.
Install the free Echo extension and your context follows you across ChatGPT, Claude, Gemini, and Cursor.
