AI memory
AI memory that works across your tools
AI memory is what lets an assistant remember you instead of starting every conversation from a blank slate. The problem is that most AI memory is locked inside one app. Echo is an AI memory system that works across all of them.
Install it once and the same memory follows you across ChatGPT, Claude, Gemini, Cursor, and AI agents — so you stop re-explaining your project, your preferences, and your history every time you open a new chat.
What is AI memory?
AI memory is the layer that lets an AI assistant remember you — your context, your preferences, the decisions you already made — instead of treating every conversation as the first one. Large language models are stateless by default. Each new chat starts empty, and the moment a session ends or a context window fills up, the model forgets everything you told it.
An AI memory system fixes that by storing the important parts of your conversations and feeding them back when they are relevant. Good AI memory is not a transcript dump. It captures the names, numbers, projects, and decisions that actually matter, and surfaces them at the right time so the assistant picks up where you left off.
Why most AI memory is trapped in one app
Every major AI tool is building its own memory — and keeping it inside its own walls. ChatGPT memory only works in ChatGPT. Claude memory only works in Claude. Gemini remembers things only inside Gemini. The result is a set of disconnected silos: the context you built up in one tool is invisible to the next.
For anyone who uses more than one model — and most people now do — that means re-explaining the same project, pasting the same brief, and rebuilding the same context over and over. Your memory becomes a function of which app you happen to have open, not of what you actually know.
How Echo’s AI memory system works
Echo is an AI memory layer that sits across your tools instead of inside one of them. You install the free Chrome extension, sign in, and Echo starts capturing the context from your conversations — one click, no configuration.
That memory is then available everywhere Echo connects. When you switch from ChatGPT to Claude, or open Gemini, or jump into your editor, the relevant context comes with you. You stop re-explaining yourself and the assistant stops starting from zero.
- Capture the context, decisions, and details from any supported chat in one click.
- Store them as structured memories you can search, edit, and organize.
- Recall them automatically across ChatGPT, Claude, Gemini, Cursor, and agents.
AI memory for agents and IDEs
AI memory is not just for chat. Coding agents and IDEs need it most, because they work across many sessions on the same project. Echo connects to editors and agents like Cursor through MCP, so the research and decisions from your chats are available where you write code.
That turns a one-off conversation into durable project memory. Your agent stops ignoring the context you already built, and you stop copy-pasting the same architecture notes into every new session.
Your memory, under your control
Memory this useful only works if you trust it. Echo is built so your memory belongs to you: you can browse it, edit it, export it, and delete it at any time. It is portable across tools by design, which means you are never locked into a single platform to keep your own context.
Start free. The Echo extension installs in one click and works on ChatGPT, Claude, and Gemini right away — no API key needed for the browser.
AI memory FAQ
What is AI memory?
AI memory is a layer that stores the important context from your AI conversations — names, projects, decisions, preferences — and feeds it back when relevant, so the assistant remembers you instead of starting each chat from scratch.
Do AI models have memory by default?
No. Large language models are stateless: each new conversation starts empty, and once a session ends the model forgets it. Built-in features like ChatGPT memory only persist inside that one app. Echo adds memory that works across tools.
What is an AI memory system?
An AI memory system captures, stores, and recalls your context across sessions and tools. Echo is a cross-platform AI memory system that works across ChatGPT, Claude, Gemini, Cursor, and AI agents.
Is Echo’s AI memory free?
Yes. The free plan includes daily memories, a history import, and cross-tool matching. The Chrome extension is free to install, and you can upgrade to Pro for unlimited memory and deep search.
Can AI agents use Echo’s memory?
Yes. Echo connects to IDEs and agents like Cursor through MCP, so your context is available where your agents run, not just in chat.
