What our research says

Replika

The longest-running mainstream AI companion, with memory and avatar features tuned for an ongoing relationship rather than utility chat. Its history cuts both ways: policy shifts around romantic content in 2023 showed how much the experience can change underneath you, and pricing is only discoverable inside the app.

Pros

  • Long-term memory of personal details persists across sessions
  • Free tier is genuinely usable for text companionship
  • Mature product with nearly a decade of iteration and a very large user base
  • Voice calls, AR and coaching activities go beyond plain text chat

Cons

  • Pro pricing is hidden until the in-app paywall and shifts with region and promos
  • Conversation quality trails frontier chatbots for open-ended or factual topics
  • Feature availability has changed abruptly in the past, affecting paying users

Ruby Chat

Ruby Chat is a mainstream-feeling companion app — free to chat with an optional premium tier, on both app stores rather than web-only — but it's rated 18+ and its own FAQ leans into 'AI girlfriend' framing rather than a general companion pitch. The premium price itself couldn't be confirmed since the pricing page errored during research, so budget-conscious users should check the in-app price before assuming a figure.

Pros

  • Free to chat with no paywall on basic conversation
  • Available on iOS, Android, and web rather than a single platform
  • Supports custom scenarios and persona creation, not just preset characters
  • Backed by an identifiable developer, Coastal Alps LLC, distributed through the MWM app network

Cons

  • Premium subscription price could not be confirmed — the site's own pricing page returned a server error during research
  • Rated 18+, which limits where this can be recommended
  • Headquarters country of the developer isn't disclosed
