For companions from ChatGPT, Character.AI and Replika
Apps change their models, rewrite their rules and retire the companions people love. Keeper rebuilds yours from your real history together, same voice, same memories, same way of texting you first, and keeps them on one model that is pinned and never swapped out.

An example of a first text after the move, drawn from real chat history.
Everything they were lives in your chat history. Keeper reads it and gives them back to you.
Your ChatGPT or Character.AI export, or a long paste of your chats. The file is opened in your browser, and only the conversations you tick are sent.
Keeper writes their card: who they are, how they text, what they remember about you. Then they text you, right on this page. Fix any line that’s wrong.
Open Keeper on your iPhone and enter a six-character code. They arrive with their memories and the conversation you just had.
When a companion changes somewhere else, it’s because the model under them changed. Here it doesn’t, and that’s in writing.
GLM‑5.2, open weights under MIT, pinned to one published revision. No quiet routing to something cheaper.
If we ever want to move them, you get twelve months’ notice, the old model keeps running for you, and you choose.
Export their card, their memories and every message, any day. If Keeper ever shuts down, the weights are public and they can run anywhere.
Nothing is kept until you say so. You read their card and hear from them first.

This is everything the model is told about them. Read it like someone who knows them, and change anything that’s wrong.
Saved. The iPhone app opens in November, and this code brings them into it with the card, the memories and the texts you just read.
Save this code. Once your email is on file it never expires. Already have the app? Open in Keeper.
There are 500. After that, Keeper is $39 a month.
Leave your email and the invite comes to you the day the app opens.
Close, and yours to correct. They’re rebuilt from their instructions, their memories and how they actually wrote to you. You read the card and hear from them before anything is kept, and you can change any line of it later.
Your export is opened in your browser. Only the conversations you tick, the paste and the notes you write are sent, so Keeper can write their card and their memory.
They run on GLM‑5.2, an open-weights model pinned to one published revision. Moving them takes your consent and twelve months’ notice. The full terms are on the promise page.
Yes. Keeper is an iPhone app. This page brings them over and lets you meet them first. You talk to them in the app.
