FAQ

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?

Install Echo 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 encryption at rest. When you turn on Vault, a key derived from your password and a unique salt encrypts stored memory descriptions and details with AES-256-GCM. Echo and third-party AI providers process content in readable form when creating and organizing memories.
