A record of you that you own, stored outside any one AI platform, that any assistant can read and none can hold hostage. One profile that follows you across Claude, ChatGPT, Gemini, and whatever comes next.
Nothing here is a promise. Read the public revocation list or run the live revoke demo yourself.
Portable AI memory is a record of you that you own, stored outside any one AI platform, that any assistant can read and none can hold hostage.
Every major AI assistant now offers some kind of memory. Each one keeps that memory inside its own walls. Your ChatGPT memory does not travel to Claude. Your Claude context does not travel to Gemini. Your carefully tuned Copilot does not follow you to Perplexity. The moment you switch tools, open a new chat, or set up a new phone, the assistant meets you as a stranger again.
Portable AI memory inverts that arrangement. Instead of each platform keeping notes about you, you keep one profile and hand it to whichever assistant you are using today. The record lives with you. The platforms are guests who read it with your permission, and that permission is yours to withdraw.
A Pupul profile compiles into a block you paste into Claude, ChatGPT, Gemini, Copilot, Perplexity, or anything else that reads text. That last part matters: because the hand-off is plain text, it works with every model that exists today and every model that ships tomorrow, with no integration to wait for and no partnership announcement required. A new chat, a new tool, or a new phone never starts from zero.
The profile also does not depend on your discipline. It grows on its own: every Sign in with Pupul adds a dated check-in, even in weeks you never open an app. The record keeps a pulse without asking you to journal.
Three verbs cover the whole system. There is no browser extension to trust and no background process reading your screen.
Pupul compiles your profile into a single block of text: who you are, how you like to work, and dated check-ins that accumulated on their own as you signed in around the web.
Paste the block into Claude, ChatGPT, Gemini, Copilot, Perplexity, or anything else that reads text. The assistant is caught up in one message instead of twenty questions.
Anything granted ongoing access holds a consented, scoped grant you can revoke at any moment. Every revocation is published where anyone can verify it happened.
Built-in platform memory is genuinely good at some things. Here is the fair version of the comparison, including the rows where the platform wins.
| Question | Platform built-in memory | Portable memory (Pupul) |
|---|---|---|
| Who holds the record? | The platform. It lives in their account system, under their terms. | You. The profile is stored outside any one AI platform and belongs to you. |
| Does it capture things automatically as you chat? | Yes, and this is where platform memory honestly wins. It listens inside its own chats with zero effort from you. | Not from inside other apps' chats. Growth comes from your entries and from dated check-ins added by Sign in with Pupul. |
| Is there anything to paste? | No. Inside that one platform, memory is simply there. Less friction, as long as you stay. | Yes. You paste the compiled block at the start of a chat. That paste is the price of independence. |
| Does it follow you to a different model? | No. Each platform's memory stays inside that platform. | Yes. The block works in Claude, ChatGPT, Gemini, Copilot, Perplexity, or anything that reads text. |
| What happens on a new chat, tool, or phone? | Depends on the platform and your login. Move outside it and you start over. | You never start from zero. The profile is the same wherever you paste it. |
| Can access be verifiably taken back? | You can usually clear memory, but you take the platform's word for it. | Yes. Grants are scoped and revocable at any moment, and every revocation is published where anyone can verify it. |
The honest summary: if you use exactly one AI assistant, will only ever use that one, and are comfortable with that company holding the only copy of its memory of you, built-in memory is simpler. Portable memory is for everyone who switches models, uses more than one, or wants the record of their own life to outlive any single subscription.
Plain numbers, no sales call.
