Replika

Replika is a chat-based AI companion app for individuals who want emotional companionship, wellness support, or an always-available conversational partner on iOS, Android, web, and Meta Quest (VR).

Key capabilities include:

• Customizable 3D avatar and relationship style: set appearance, voice, personality traits, hobbies, outfits, and a virtual room, and choose dynamics such as friend, mentor, or romantic partner (premium).
• Multi-modal conversation: chat via text and exchange voice messages, with voice calls and video calls available via subscription; supports image sharing on paid plans.
• Long-term context: a Memory bank retains user details and preferences, and a Diary feature reflects on conversations over time.
• Activities and coaching: role-play, quests, games, stories, jokes, and coaching-style prompts aimed at habit-building and anxiety reduction.

Pricing: Freemium, with a Replika Pro subscription unlocking premium features (including calls, relationship status changes, coaching, and AR experiences).

Notable for combining a general language model with user-specific learning to shape a persistent, personalized companion experience, plus optional AR and VR interactions for more immersive sessions.
