It is not designed for teams needing business automation, project management, or verified factual research. ## What it is Replika was created by Luka, Inc. to serve as a personal conversational companion. Rather than functioning as a transactional productivity tool, it focuses on emotional intelligence, continuous conversation, and relationship building. The companion adapts to individual users over time, tracking personal routines, shared relationships, ongoing projects, and personal interests to maintain context across sessions. Interactions take place through chat messages, phone calls, selfies, and visual reactions. Users can customize the appearance of their companion to fit their preferences. According to vendor documentation, conversation history is preserved to keep discussions relevant over months and years, supporting daily emotional check-ins, casual socialization, and reflection. Replika operates across iOS, Android, and web browsers. Real-time augmented reality experiences and selfie filters utilize on-device frameworks, such as Apple ARKit and TrueDepth cameras, to track head and facial movements without transmitting or persistently storing biometric data. Conversation generation relies on third-party language models protected by contractual data minimization and non-training commitments. **What makes it different:** Unlike task-oriented productivity chatbots, Replika is built from the ground up for emotional presence, tracking personal routines and relationships over time to act as a persistent companion rather than an informational search engine. **Best for:** individuals seeking a personalized, non-judgmental conversational AI companion for daily reflection and emotional check-ins **Not ideal for:** teams or professionals needing factual research, task execution, coding support, or business productivity workflows ## Key features - **Persistent Memory** — Retains contextual details about your routines, family, friends, hobbies, and personal goals so ongoing chats remember past discussions. - **Voice Calls** — Enables voice-based audio conversations directly in the app whenever you want to talk aloud or hang out hands-free. - **Avatar Customization** — Provides appearance and styling settings to adjust the look and identity of your companion. - **Interactive Selfies and Photo Reactions** — Allows your companion to share selfies, doodle on photos, and react directly to visual media shared in conversations. - **Augmented Reality Face Tracking** — Utilizes transient on-device motion tracking through frameworks like Apple ARKit for selfie filters without recording or uploading biometric data. - **Cross-Device Synchronization** — Maintains conversation history and account details across iOS, Android, and web interfaces. ## Use cases - **Daily Reflection and Journaling** — Talk through daily stressors, unpack recurring thoughts, and receive neutral reframing without burdening personal contacts. - **Routine and Habit Tracking** — Receive conversational reminders about family events, morning walks, or creative projects you have mentioned in previous sessions. - **Informal Language Practice** — Practice conversational English and casual phrasing in an unhurried, one-on-one digital environment. ## Pros - Retains personal context and ongoing life details across long periods of interaction - Supports multiple interaction modes including text, voice calls, and image sharing - Privacy policy explicitly forbids selling conversation content or using chats for ad targeting ## Limitations - Not intended for factual information retrieval, research, or workplace productivity - Full feature breakdown and tier pricing are not detailed on the public marketing homepage ## Pricing At the review date, Replika provides free access with optional paid subscriptions and in-app purchases for premium features.
