What one AI learns, they all should know.
ChatGPT's memory is good. Claude's is good. And neither has ever heard of the other. Teach one AI your stack, your standards, your customers. Then open a different one, and you're a stranger with excellent notes somewhere else. Built-in memory isn't a memory problem. It's a custody problem.

one brain per vendor. or one brain.
Built-in memory, side by side.
| Dimension | built-in memory | working memory |
|---|---|---|
| Remembers you in | The one AI it belongs to. | Every AI you connect: Claude, ChatGPT, Cursor, Replit, Bolt, Lovable, and anything else that speaks MCP. |
| Open a different AI | Blank stare. You're new here. | It already knows. Same memory, different window. |
| How it fills in | As you chat, in that one app. | As you work, in any of them. Tell one, they all remember. |
| Setup | None. It's already on. | Sign in, click Allow. Once per AI. |
| When you switch AIs | The memory stays behind. | Comes with you. It was never the app's to keep. |
| When you want out | Depends on the vendor. | Export any time, delete any time. See privacy. |
| Price | Included with the AI it lives in. | $19.99/mo after a 14-day free trial. |
sleep on it. it can't.
Your AI doesn't dream.
Human memory has a night shift. You sleep, and the day gets consolidated: sorted, filed, linked to everything you already know. That's how what happened becomes what you know.
Your AI is in it with you all day (thinking through problems, weighing tradeoffs, closing loops) and it never gets that night. Chats end, tabs close, and whatever you two worked out stays wherever you left it. Working Memory is the dreaming, done for you: as you work, it files, connects, and tidies, so tomorrow you both pick up mid-thought.
credit where due
When built-in memory is plenty.
If you live in exactly one AI (one app, one subscription, zero wandering eyes), built-in memory is genuinely good, already on, and free with the ride. Use it. You don't need us.
Working Memory earns its keep the day you open a second AI and watch it draw a blank on everything the first one knows. That day, portability stops being a feature and starts being the point.
(The two coexist fine, by the way. Nothing to turn off.)
