privstory vs Character.AI

Character.AI is the app that made character chat mainstream, and for a lot of people it's also the app they started looking to replace, usually after a model change or a tightened filter altered characters they'd spent months with. privstory is built on the opposite trade-off: everything runs on your own machine, so nothing about your characters is anyone's to change but yours.

How the two compare on the things people switch over.
Feature Character.AI privstory
Where it runs Character.AI's cloud servers Your own computer
Account Required to use it None needed, no sign-up
Where your chats are stored On their servers, tied to your account A local database on your disk, fully private
Pricing Free tier, plus an optional monthly subscription One-time license
Message limits Subject to rate limits and server load None, your hardware is the only limit
Content moderation Server-side moderation, known for being strict No server-side filter; the module you pick decides
Works offline No, it needs a connection Yes, after a one-time model download
Image generation Focused on text; not the core feature Local portraits and scenes on your GPU

Why people go looking for a Character.AI alternative

The recurring complaint isn't the quality of the chat, which many people like. It's that the experience is subject to change. A model gets swapped, the moderation gets stricter, and a character that felt consistent starts refusing or responding differently, with no way to go back to how it was.

That's an unavoidable property of a hosted service: the model and the rules live on their servers, so they can and do change under you. privstory removes that exposure by moving the model onto your machine, where it is a file that stays exactly as it was until you decide otherwise.

What privstory does differently

There's no account and no server in the loop. You download the app, download a module's models once, and everything after that, creating characters, chatting, generating portraits and scene backdrops, happens locally and works with the network switched off.

Because the compute is yours, the mechanics that shape a cloud service disappear: no message rate limits, no subscription, and no server-side filter, because there is no server for a filter to sit on. What a character will and won't say is set by the module you choose, and you can build your own or import one.

Who should stay on Character.AI

This is a real trade, not a free lunch. Character.AI runs on any device with a browser, syncs your characters across them automatically, and needs no capable hardware, because the heavy lifting is on their servers. privstory asks for a reasonably modern computer, ideally with a GPU, and its library lives on the machine you made it on, with no automatic cross-device sync.

If you mostly chat on a phone, want your history everywhere with zero setup, and the platform's filter has never bothered you, a cloud app is genuinely the easier fit. privstory is for people who would rather own the whole thing outright and keep it private, and who have a machine that can run it.

Common questions.

Is privstory free like Character.AI?

There's a free version with no account and no payment, limited to one character and one scene, with the full local chat and image generation. A one-time license unlocks unlimited characters and scenes. There is no subscription either way.

Can privstory import my Character.AI characters?

No. The two store characters completely differently, and privstory generates characters from your own one-line brief using the module you choose. There is no import from Character.AI.

Does privstory have the same content filter?

No. There is no server-side moderation, because there is no server: your conversation never leaves your machine. A character's behaviour is set by the module you select. privstory is intended for adults, and illegal material is illegal wherever it's generated.

Do I need a powerful computer to replace Character.AI?

You need more than a browser, since the models run on your hardware rather than theirs. A recent Apple Silicon Mac or a machine with a discrete GPU runs comfortably; a CPU-only machine works but image generation is slow.
