Let me introduce you to someone
Never repeat yourself to AI again.
One shared memory for 
Claude, 
Cursor, 
Codex, and every MCP tool — so your AI remembers your stack, your decisions, and your taste. Brief it once, not every session.

Every session, your AI re-reads context you already gave — burning tokens and your time. EchoMem remembers it, so you hit your limits less and finish faster.

Here is the thing
Sam has the same week twice.
In one version
His AI remembers bits and pieces. Not the whole story.
So every morning
Sam explains the project again. The same files. The same decisions.
In the other version
EchoMem brings the context back. Sam just keeps going.
After a while
One desk feels messy. One feels like it remembers him.
That is the difference
60% fewer tokens. A lot less repeating himself.

Your memories are encrypted on your device before anything is saved. Nobody — not even Echo — can read them. Only you hold the key.

echomem-mcp setupFAQ
What is portable AI memory?
Portable AI memory is context that moves with you across AI tools. Echo saves the names, decisions, project details, and working context from one conversation and brings them into ChatGPT, Claude, Gemini, and your coding tools.
How is Echo different from ChatGPT's built-in memory?
ChatGPT's memory only works inside ChatGPT. Echo is cross-platform: what you told ChatGPT is available in Claude, Gemini, and your IDE, so your context isn't locked inside one app.
How do I get started, and is it free?
Install the free Echo extension from the Chrome Web Store, sign in, and it works on ChatGPT, Claude, and Gemini right away. There is no configuration beyond one click.
Does Claude remember what I told ChatGPT?
Not by itself — but with Echo it does. Echo carries the context you built in ChatGPT into Claude and Gemini, so switching models does not mean starting over.
How do I stop copy-pasting the same prompt or brief into every AI?
Echo saves your prompts, briefs, and project context once, then brings them into any supported chat. It replaces the manual prompt doc you keep copying from Notion, Google Docs, or old chat threads.
Can I use AI memory in Cursor or another IDE?
Echo connects to IDEs and agents like Cursor through MCP, so the research and project context from your chats is available where you code — your editor no longer ignores your research.
Which AI tools does Echo work with?
The Chrome extension works on ChatGPT, Claude, and Gemini today. Echo also reaches IDEs and agents such as Cursor via MCP, OpenClaw via a plugin, and offers an iOS app, EchoChat.
Is my data private? Is Echo encrypted?
Echo offers optional end-to-end encryption. When you set a vault passphrase, your private memories are encrypted on your device and the server stores only ciphertext — so no one, including us, can read them.
