ChatGPT memory vs. a portable AI memory you own
ChatGPT memory is convenient but locked to one app. Here's how it compares to a portable AI memory layer you own — across ownership, portability, the persona dimension, and privacy.
ChatGPT memory is one of the most useful features OpenAI has shipped. It quietly remembers your preferences and projects so you don’t repeat yourself. If you only ever use ChatGPT, it may be all you need.
But most serious AI users don’t live in one app. They have a Claude subscription and a ChatGPT subscription, switch between them through the day, and increasingly run a local model for sensitive work. For them, the question isn’t whether ChatGPT memory is good — it’s whether a memory locked to one vendor is the right place to keep something this personal.
The comparison
| ChatGPT / Claude / Gemini memory | Portable AI memory (aiperson) | |
|---|---|---|
| Where it lives | The vendor’s servers | A file in your git repo + local SQLite |
| Who holds the keys | The vendor | You (Ed25519, generated locally) |
| Works across models | One app only | Every AI at once — cloud + local |
| Switching cost | Lossy one-time copy | Already there; nothing to migrate |
| Carries the AI’s character | No — generic tool | Yes — voice, conventions, refusals |
| Export | Sometimes, vendor-shaped | Any time, open format, self-hostable |
The part the table can’t show: the persona
Vendor memory captures what the AI knows about you. It models the assistant itself as a generic, interchangeable tool. But anyone who has used one assistant heavily knows that isn’t how it feels. Over months you cultivate something: a voice, a set of conventions, agreements about what it will and won’t do, a shared shorthand.
A portable AI memory layer carries that second dimension — the persona — alongside the facts. So when you move to a different model, you don’t just keep what it knew; you keep who it was.
”But the vendors let me import my memory now”
True, as of March 2026. That import is a one-way, lossy copy — useful when you’re migrating for good, useless when you want the same memory live in three places at once. Owning your AI memory means it’s already present everywhere, with no migration step, and you hold the file regardless of any vendor’s roadmap.
Privacy: a memory you hold can’t be mined
When your memory lives on a vendor’s servers, you’re trusting their policies. When it lives in a signed file on your machine — which is how aiperson works by default — there’s simply nothing on someone else’s infrastructure to mine, leak, or hold hostage. Capture is opt-in per surface, a regex redactor runs before anything leaves the page, and you can export or wipe everything at any time.
The bottom line
Keep using ChatGPT. Keep using Claude. The point of a portable AI memory layer isn’t to replace your assistant — it’s to make the memory beneath all of them yours. See how the options compare, or own your AI memory today.
