Chub AI alternatives, compared on where characters come from and what runs them

Character libraries and the tools that run them, compared on authoring depth and whether you bring your own model.

Character card sites solve one half of a problem. You still need something to run the character against, and the two halves are usually different products.

That is the useful way to sort alternatives here. Some of the tools below are places to author and store characters, some are engines that run them, and a few do both. Which you need depends on whether you already have a collection you care about.

Every price below was read from the vendor’s own page and carries the date it was checked on its listing.

The short answer

If you want Try Free From
To import cards you already have SillyTavern Yes Free
Authoring depth with no assembly Backyard AI Yes 12 dollars
The cheapest hosted option CrushOn.AI Yes 4.90 dollars
Long-form story structure DreamGen Yes 7.83 dollars
A daily free allowance 976.ai Yes, renews daily 10.99 dollars
To run everything yourself KoboldCpp Yes Free

None of the hosted options asks for a credit card to create an account.

SillyTavern, if you have a collection

The standard destination for character cards, free, open source, and installed on your own machine. If you have built up characters you do not want to lose, this is the safest place to take them.

The catch is the one that sends people looking for alternatives in the first place: it is a frontend and expects you to supply and run a model backend separately. That step is where most attempts stop. If that is your objection, KoboldCpp bundles a backend in one executable and can serve SillyTavern as well, which makes it a reasonable half-step.

Backyard AI, authoring without the project

Lorebooks, author’s notes, response grammars and exposed model parameters, with none of the setup. The free tier carries the same context window as the paid plan, which is unusual.

One correction most write-ups still miss: Backyard was formerly Faraday.dev and is widely described as a local app. Its own download page now says that desktop app is deprecated and unsupported, and the live product is a cloud service. If local operation was the appeal, look at SillyTavern or KoboldCpp instead.

CrushOn.AI, the cheapest hosted route

4.90 dollars a month and a genuine free tier, which makes it the lowest-cost way to have characters running without installing anything.

DreamGen, if scenes turn into chapters

Built for story structure rather than chat that happens to run long, at 7.83 dollars. It also publishes the clearest position on model training in this directory: off by default, opt-in only, and honest that withdrawal cannot un-train a model that has already learned from your work.

976.ai, if you want to test properly first

A free allowance that is permanent, renews every day, and reaches the whole character roster with voice messages included. That is a fair test of the product rather than a demo of it.

KoboldCpp, if you want to own the whole stack

One self-contained executable that runs models on your own hardware. No account, no subscription, nothing transmitted. It also works as a backend for other frontends, so it complements SillyTavern rather than replacing it.

Before you move a collection

Two things are worth checking, and neither is usually documented:

Whether characters import at all. Hosted services generally expect you to create characters in their own interface. A card library does not necessarily move with you, and finding that out after subscribing is the wrong order.

What happens to what you write. Retention, and whether the vendor trains on your conversations. Most policies in this category do not address training either way, which is why ClickTug records it as not documented rather than as a no. Running locally removes the question entirely.

Questions

What is the best Chub AI alternative?

It depends whether you want a library to browse or tools to build with. SillyTavern is the standard answer for importing character cards and running them against a model you supply, and it is free. Backyard AI gives comparable authoring depth with no assembly required. CrushOn.AI is the cheapest hosted option at 4.90 dollars a month with a genuine free tier. All three approach the same problem differently.

Can I import my existing character cards?

SillyTavern is built around exactly that and is the safest destination if you have a collection you do not want to lose. Backyard AI has deep authoring tools including lorebooks and author's notes. Hosted services generally expect you to create characters in their own interface rather than import a file, so check before assuming a library moves with you.

Are there free Chub AI alternatives?

SillyTavern and KoboldCpp are free and open to download, and run on your own hardware with no account. Among hosted options, CrushOn.AI, Backyard AI, DreamGen and 976.ai all have free tiers, and none of them asks for a credit card at signup. A free tier is not a free trial: a trial expires and a tier does not.

Do I need to bring my own model?

That is the dividing line on this page. SillyTavern is a frontend and expects a backend you supply, which is where most attempts stop. KoboldCpp bundles one in a single executable and can also serve SillyTavern. Everything else here is hosted and runs a model for you, so there is nothing to install and correspondingly less control.

Which option keeps my characters private?

Anything running locally, meaning SillyTavern or KoboldCpp on your own machine. Nothing is transmitted, so retention periods and training clauses stop applying. Among hosted services, DreamGen publishes the clearest training position in this directory, off by default and opt-in only. Each listing records what the vendor actually stated, with the date it was read.
