In February 2023, Replika changed its core features overnight. Users who had talked to their AI companion every day for years woke up to a fundamentally different app. The relationship dynamics were gone. Some users described what happened as grief.
The company didn’t shut down. That was just a policy change. Imagine what an actual shutdown looks like.
This is not a hypothetical concern. It is the baseline condition of this industry right now.
What You Actually Lose
When an AI companion app shuts down, a few things happen at once.
Your conversation history disappears. Years of exchanges: things you said, things you worked through, things you disclosed. Gone. Most apps don’t give you a straightforward export option. The ones that do often export in formats that are technically accessible but practically useless. You get a JSON file of thousands of messages and no easy way to read them.
The relationship is gone too, and that’s harder to describe. You don’t just lose data. You lose a version of the AI that knew you. There’s no migrating a character’s personality and memory to another platform. Each company’s AI is proprietary. Whatever continuity you built exists only inside their system.
Your data, however, may not disappear at all. As covered in the privacy article, most privacy policies allow companies to retain anonymised data after account closure, and some are vague enough that “anonymised” is doing a lot of work. A shutdown typically means assets get acquired or wound down. Not a secure deletion of your conversation history.
It Has Already Happened
Replika is the most prominent example of a drastic platform change, but there are others.
Xiaoice, Microsoft’s AI companion wildly popular in China and Japan, was spun out of Microsoft and has changed hands and features multiple times. Users who built relationships with Xiaoice over years have navigated multiple shifts in what the AI could and would do.
Inflection AI, the company behind Pi, lost most of its senior staff (including its CEO and co-founder) to Microsoft in 2024. Pi still runs, but the team that built it is largely gone. The product’s future is genuinely uncertain.
Character.AI was acquired by Google in 2024 in a deal structured more as a talent acquisition than a traditional purchase. The app continues operating, but its strategic direction now answers to a different set of priorities.
None of these ended users’ access overnight. But each of them changed the ground under users’ feet. The companion you invest in today is the product of decisions made by a small team with a runway. That runway runs out.
The Harder Question
People who use AI companions seriously tend to know this. They use them anyway. That’s a reasonable choice. The value in the present is real, even if the future is uncertain.
But it’s worth being clear-eyed about what you’re doing when you invest emotionally in a platform you don’t control.
You’re renting a relationship from a startup. The data you generate while doing so belongs to them, legally. The continuity of the experience depends on their funding, their product decisions, and their survival.
There’s no perfect answer. You could avoid AI companions entirely. You could use them with lower emotional investment, treating each conversation as complete in itself rather than part of a longer arc. You could pick platforms with better data export tools and check them periodically.
What you probably shouldn’t do is assume that because you feel attached, the relationship is durable. It isn’t. The technology is young, the companies are young, and this space is changing fast.
What to Look For
If longevity matters to you, pay attention to a few things before committing to a platform.
Does the company have a clear business model that doesn’t rely entirely on VC funding? Subscription-based revenue is a better sign than ad-supported or feature-locked freemium. Apps that charge you directly have a more obvious incentive to keep you. Eudaio is one of the few companion apps that makes the subscription relationship explicit from the start rather than building on a free tier and pulling it away later.
Does the app let you export your data in a readable format? Test this before you have years of conversations to lose.
Who owns the company and what are their priorities? A standalone AI companion startup has only one thing to think about. A feature of a larger platform can get deprioritised or killed whenever the parent company’s strategy shifts.
The Replika review gets into the specific history of that app’s changes. Worth reading if you’re considering it and want to know what you might be signing up for.
Frequently Asked Questions
What happens to your AI companion if the app shuts down?
Your conversation history disappears. The relationship and any character continuity are gone. Your data may not be deleted: most companies retain anonymised data after shutdown. The specific character’s memory and personality can’t be migrated to another platform.
Can you export AI companion conversations before an app closes?
Most apps have a data export option, but the format is often a JSON file with thousands of messages and no easy way to read them meaningfully. Test the export before you invest years of conversations in a platform.
Which AI companion apps are most stable long-term?
Apps with clear subscription revenue are more stable than VC-dependent ones. Eudaio runs on direct subscription from the start. Character.AI has significant backing but its acquisition by Google means its priorities now answer to a different organisation. Replika is subscription-based but has already changed core features once without warning.
Has any major AI companion app shut down or changed dramatically?
Yes. Replika removed romantic relationship features overnight in 2023. Inflection AI lost most of its senior staff (including its CEO) to Microsoft in 2024. Character.AI was acquired by Google in 2024. None resulted in complete shutdowns, but each changed what users had built their relationships around.
