What our research says

Character.AI

Still the deepest character library and the most complete roleplay feature set in the category, but since 12 October 2026 the company is in Chapter 11 with a court-supervised sale due around late November, and it says the platform will be wound down if no bid arrives. Fine for adults who chat casually on the free or monthly plans; think twice before prepaying a year or building a community around characters that live only here.

Pros

  • Character library far larger than any competitor's, with voice calls, group chats and Lorebook world notes
  • Free tier keeps unlimited messaging and gained the PipSqueak 3 and ShortSqueak chat styles in late September 2026
  • A $4.99 lite plan now sits under c.ai+, cutting ads and slow mode without the full subscription
  • Account data can be exported from the app or the website

Cons

  • The Chapter 11 sale puts the service's future in a buyer's hands, with a wind-down if nobody bids
  • The CEO left for Disney in September 2026, with members of the technical team expected to follow
  • Adults pass a third-party age check and under-18 accounts lost open-ended chat
  • No public API found, and Charms are a second currency on top of the subscriptions

TheirSide

TheirSide covers a specific niche well: multi-character group roleplay, which most character-chat apps treat as an afterthought. The free tier is workable for casual use, but heavier users will hit conversation and group-room caps quickly and the product itself is still an early-stage, small-team effort.

Pros

  • Supports up to four AI characters in one group chat, not just 1:1
  • Lets you upload reference material to shape a custom character
  • Story-scene mode gives structured scenarios instead of open-ended chat only

Cons

  • Free plan caps conversation rounds and limits you to one group room a month
  • Company behind the product discloses no country or legal entity

Choose TheirSide if you need

  • People wanting group chats with multiple AI characters at once
