What Chub AI actually is
Chub is a hub for character cards: people build roleplay bots with a personality, lorebook and greeting, then share them. You chat with them in Chub's own front end, with chat trees, presets and add-ons it calls Stages. Its guide says plainly that Chub is uncensored and barely restricts what cards or chats are allowed.
You power the chat with your own key from one of the big AI providers, a model running on your own machine, or Chub's in-house models sold under the Mars name. There is an iOS app too.
Pricing and the catch
Bring your own key or local model and Chub itself costs nothing; you pay the provider instead. Chub's guide lists a Mars subscription at $20 a month with unlimited messaging, and non-subscribers get a few trial messages on its newest model. The catch is effort. This is a toolbox, not a showroom, and you will spend time on presets before the chats sing.
Our verdict
For text roleplay nerds, Chub is a playground. For anyone who wants to watch something, it is the wrong tool. If a slow, teasing clip made from a photo is more your speed, Teasemo is our pick: 35 free credits to try, then one-time packs from $13 and no subscription.
