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

Pika Agents

Pika Agents turns Pika Labs' video-generation engine into a persona-chat product: a custom-voiced AI character that texts, calls, and posts on a user's behalf across many apps, with real memory between sessions. It lives on an experimental subdomain of Pika's site rather than the flagship product, and every action draws down purchased tokens rather than sitting behind a flat monthly fee.

Pros

  • Genuine multi-app reach: Slack, WhatsApp, Telegram, Discord, iMessage and more from one persona
  • Keeps memory across sessions instead of resetting each chat
  • Backed by Pika Labs' existing video, image, and audio generation stack
  • Assigns the agent a real phone number for calls

Cons

  • Runs on tokens, so cost is unpredictable relative to usage
  • Hosted at an 'experiment' subdomain rather than the main product domain, suggesting it could change or fold into another product
  • Android app not available yet

Which one fits

Choose Character.AI if you need

  • Adults who want long-running roleplay with persistent personas
  • People building and sharing characters for an existing community
  • Casual conversational entertainment rather than task work

Choose Pika Agents if you need

  • People who want one AI persona reachable across many chat apps
  • Existing Pika users who want the same account extended into agents
  • Anyone wanting a phone-reachable AI character with a real number
