Because forgetting is the default and remembering is a product feature. Models do not retain anything between conversations on their own; the app around the model decides what to save, and each app saves it only for itself.
Inside one product, memory features carry some things across chats: ChatGPT saves selected facts, Claude projects keep instructions, Gemini keeps saved info. Between products, nothing persists at all. Every new tool meets you as a stranger because your context is stored in the last tool’s silo, and silos do not talk.
Re-explaining yourself burns the first ten messages of every new relationship with an AI. Worse, it quietly locks you in: after a year of teaching one assistant who you are, switching to a better one means starting broke. Your own history becomes the reason you stay with a worse product.
The fix is to stop storing yourself in their products and start carrying one record of your own. A Pupul profile is that record: free to start, dated the day each entry lands, compiled into a block you paste into any AI in about two minutes, scoped line by line, revocable at any moment with proof a stranger can check offline. New chat, and it already knows how to meet you.
Every platform named on this page will hand you your own export if you ask. The free Count opens that file in this browser and prints what is in it: how many records, over how long, and which categories you were filed under. It counts, and it shows you the shape of the file. No account, no email field, and the file never leaves your device.
Open the free CountThe Reading, the paid page that reads a file back to you in plain sentences with a receipt on every line, is the step after. 6.99 a week or 69.99 a year, and the Count stays free either way.
Context windows reset per conversation, and persistent memory is a deliberate product layer with real privacy weight. Companies ship it walled because that is both safer for them and stickier for you.
Plain pasted text works everywhere today, and consent-scoped grants like Sign in with Pupul layer verification and revocation on top for apps that integrate it.
