Character.AI

  • +Enormous library of millions of user-created characters and a simple no-code character creator
  • +Multimodal consumer experience: text, voice calls, group chat, image generation, and AvatarFX video
  • +Runs on its own proprietary models, and the free tier historically had no hard message cap
  • -Assistant-only: characters respond in chat and take no actions, with no tools, browsing, or automation
  • -No public API and a closed proprietary model, so it cannot be embedded in external workflows
