What our research says

Character.AI

Still the deepest character library anywhere and the reason the whole companion category exists, but it has been rebuilt around safety and identity checks, and the audience it was famous for is now locked out.

Pros

  • Character library is far larger than any competitor's, with voice calls and group scenes included
  • Free tier is genuinely usable, with the subscription mostly buying speed and memory
  • Safety changes are unusually explicit about what was removed and when

Cons

  • Age assurance defaults to face-based estimation, which is a hard stop for privacy-minded users
  • Charms are a second currency on top of c.ai+, so the $9.99 is a floor not a ceiling
  • No API, no export, and no self-hosting
  • The platform has been reshaped by wrongful-death litigation, and further restrictions are plausible

Pirr

Pirr is a narrow, well-executed take on AI fiction: it does romance, it does choices, and it does not pretend to be a general writing tool. Keeping adult content opt-in rather than the headline act puts it closer to a reading app than to a companion chatbot. Pricing is the weak spot — plans sit behind signup and the vendor names no company anywhere.

Pros

  • Native iOS and Android apps plus a web beta
  • Choice-driven branching rather than a plain chat log
  • Wide genre picker including LGBTQ+ and historical
  • 18+ content is off by default and gated in settings

Cons

  • Pricing is not visible before you create an account
  • No named legal entity or address on the site
  • Premium turns are metered, so heavy readers hit the cap

Which one fits

Choose Character.AI if you need

  • Adults who want long-running roleplay with persistent personas

  • Casual conversational entertainment rather than task work

Choose Pirr if you need

  • readers who want branching romance on a phone
