What our research says

Abby

Abby is upfront about its own limits, which matters more than usual in this category: it states plainly it is not a licensed therapist and cannot diagnose or treat anything, and points toward real therapists when that's what's needed. Within that scope it offers a reasonably full-featured companion -- voice mode, memory, multilingual support -- but as with any AI companion for emotional support, it can't replace a human clinician in a genuine crisis.

Pros

  • Explicitly and repeatedly disclaims being a substitute for licensed therapy, rather than overstating its role
  • Adjustable persona, reply length and directness instead of one fixed tone
  • 88-language support with voice as well as text
  • Includes a therapist-matching service pointing toward professional help

Cons

  • Subscription price is not shown on the website, only inside the app
  • Memory and proactive check-ins mean sensitive conversations are stored by the vendor
  • As an AI companion, it cannot handle genuine crisis situations

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
