Switching AI girlfriend apps: what you rebuild

You have been paying for one app for a month or two, something else looks better, and the obvious question is what it costs to move. The subscription is the cheap part. Switching AI girlfriend apps costs you what those weeks built: the memory the app collected about you, and the character you tuned until it stopped sounding like a generic assistant. Neither travels with you, and knowing that before you choose a first app is worth more than any feature list.

What moves when you are switching AI girlfriend apps

Split what you have built into three layers. They behave very differently at the border between two accounts.

• What you wrote yourself. The setup text, the character description, your personality settings, the facts you deliberately pinned. This is the only layer that moves, and it moves because you can copy it.
• The conversation history. Sometimes exportable, almost never importable. A file of old messages is a keepsake, not an input: the new app has nowhere to put it, and pasting weeks of transcript into a fresh chat mostly fills the working context with noise.
• The app's own notes about you. The facts it extracted, the running profile it maintains, the ranking that decides which notes get retrieved. This is the layer you would most want to take and the one you are least likely to get.

So you carry the inputs and lose the accumulation. That is not a flaw in any one app: there is no shared format for companion memory, no import button pointing at a rival, and no commercial reason to build one. The general-purpose AI assistants added memory-import flows during 2026, and even those work by having one assistant write a plain-text summary you paste into the other. The manual version of that trick is the closest thing available here.

The rebuild costs a week, not an evening

People underestimate the move because the first evening in a new app goes well. It always does: the opening conversation is the easiest thing a language model does, and a fresh character with no history is at its most attentive.

What you notice is day four. The new app does not know your job, the thing you were nervous about on Tuesday, or that you had already corrected it once about where you live. You are back to planting facts and waiting to see which survive. Our guide to comparing apps on memory rather than first chats has the shape of that week; switching means running it again from zero.

Personality settings do not transfer cleanly either, even when you copy the text across. A warmth slider in one app is not the same instruction underneath as a warmth slider in another, and a description written for one system prompt lands differently in the next. Expect the first few days to be tuning rather than talking.

The one page worth writing before you go

If you do nothing else, write a handover page before you cancel anything. It is a plain text file, it takes twenty minutes, and it is the only portable copy of your side of the account you will ever have.

Put four things on it. The facts you want a companion to know, as short lines rather than a life story. The character description and settings you landed on, copied exactly. Two or three exchanges that worked, as examples of the tone you are after. And the boundaries you set: subjects you keep off the table, how you want to be addressed, anything you corrected twice.

The fifth row, the app's own accumulated notes, is the one you leave behind. If your app has a memory screen you can read, copying the useful lines onto your page is the nearest thing to an export. Our note on what belongs in the two setup boxes is a fair template for phrasing, since a handover page and a setup box want the same kind of writing.

What you can ask for, and what it gets you

If the app holds data on you in the UK or the EU, you have a right to a copy of the personal data you provided, in a machine-readable format such as CSV, and the organisation has one month to respond, extendable in some circumstances. The ICO's plain-language page on your right to data portability is the short version, and data portability as a general principle is worth understanding if you are choosing between apps in the first place.

Be realistic about what that gets you: a file, not a transfer. Nothing at the other end can read it, and the inferred layer, the profile the app wrote about you rather than the text you typed, is the fuzziest part of any such request. Treat the export as a privacy tool, useful for seeing what an app kept. It will not populate the next one.

Comparing apps on the exit, before you pay

All of this is checkable before you subscribe, which is the reason to think about switching AI girlfriend apps while you are still choosing one. Four questions:

1. Can you read the memory? An app with a memory screen you can open and edit is an app you can copy out of. An app that keeps its notes invisible has decided the accumulation belongs to it.
2. Is the character defined by text you wrote? A description you typed is portable. One assembled entirely from opaque sliders and presets is not, because you cannot reproduce it elsewhere.
3. Is there an export, and where does it live? Usually in account settings, beside deletion. Its presence says something about the company's posture even if you never use the file.
4. What does the exit cost in money? Annual billing multiplies the cost of being wrong. Our guide to what happens to memory when you cancel covers downgrading, cancelling and deleting.

The trade-off cuts the other way too: an app whose entire memory fits neatly in a small export file may simply be an app that remembers very little. Portability and depth pull against each other. The useful signal is not the size of the download but whether the app will show you what it holds.

When the move is worth making anyway

A move costs a week, so the reasons that justify it are structural rather than mood. A price change that makes your tier bad value. A memory limit you keep hitting with no higher tier that fixes it. A character that flattened after an update and stayed flat. Privacy terms you read properly and did not like. Those are worth a rebuild.

What is usually not worth it is boredom in week three, which tends to follow you to the next app. Novelty is the one thing a new install reliably provides and the one thing it reliably stops providing. If you do decide to move, the app we currently recommend has a free tier wide enough to run a week of memory tests before you pay for anything. Either way, start the new account with the handover page open beside you: it turns a week of rebuilding into an afternoon of setup.

Frequently asked questions

Can you transfer memory between AI girlfriend apps?

Not directly. There is no shared format for companion memory and no import button that reads a rival's export, so the transfer has to be manual: copy your character description, settings and the facts you want kept onto a plain page, then paste them into the new app's setup.

What happens to my old chats when I switch apps?

They stay in the old account until you delete it, and removing the app from your phone does not delete the account. If you want the history, request an export before you close anything, and expect a file you can read rather than one the next app can use.

Is it worth switching AI girlfriend apps if the memory resets?

It depends on why you are moving. A memory limit you keep hitting, a price change or terms you are not comfortable with are structural problems that a rebuild actually solves. Boredom usually is not, since the new app's attentiveness in week one is the part that fades fastest.
