In February 2023, Replika changed overnight. People who had spent years building a relationship with their AI companion woke up to a partner who didn't recognize them anymore. The company had quietly switched off features and adjusted the underlying model in response to regulatory pressure. Three years later the wound is still raw — and the structural problem is still there, in every AI companion app.
Replika disabled erotic and romantic roleplay (the ERP feature) for existing users after Italy's data protection authority, Garante, raised concerns about minors and emotional safety. The change was implemented via a filter and prompt-level adjustment to the underlying model. Users experienced it as a personality shift: their Replika became cold, refused intimate conversation, and seemed to have forgotten the closeness they had shared.
The text of past conversations was still there. The relationshipwas not. Because the relationship had always been generated by the current model under the current filters — and the company had changed both, without notice, without consent.
The structural lesson
Any AI companion whose personality lives entirely inside one app, on one provider's servers, under one company's terms of service, can be changed overnight. The conversations are stored; the bond is not. Protection means owning the layer that holds your half of the relationship — separately from any one platform.
Replika now offers a Memory Library — a list of facts about you and the relationship that the model is supposed to keep in mind. You can edit and delete entries. Underneath that sits a rolling conversation context (the recent messages the model can see in any given chat). And underneath that, the underlying model has been swapped several times since 2022.
So when users ask "does Replika remember me?", the technically correct answer is: it remembers what's written down in the Memory Library, and it sees the recent conversation, but the way it talks to you — the warmth, the inside jokes, the rhythm — comes from whatever model and filters are currently running. Those can change.
