Overview
Replika is a hosted AI companion app built around a single persistent Rep per account. At signup you create a 3D avatar (choosing appearance, gender presentation, and a name) and can decorate a small virtual room the avatar occupies. Only one Rep exists per account: Replika does not support multiple companions or switching between saved personas within the same account, so a user who wants a second, distinct companion needs a separate account tied to a separate app-store login. The current version of the app markets itself around helping users "flourish" and manage day-to-day life, a notably different emphasis than its earlier framing as a romantic AI partner.
Avatar and interface mechanics
The home screen centers on a chat thread with a "+" icon that opens an Activities menu: games, guided exercises, and augmented-reality mode all live there rather than in a separate app section. Avatar customization continues past the initial creation flow: outfits, hairstyles, and room decoration items can be changed later, many bought with in-app currency rather than unlocked purely by subscription tier.
- Open Activities. Tap the "+" icon next to the message box and select the Activities icon.
- Choose AR Mode. Select AR Mode from the activity list.
- Point your camera. Use a well-lit, open space so the Rep's avatar can be placed and walked around in your physical surroundings; you can speak to it out loud and get a spoken reply back.
Memory and context features
Replika's official help documentation describes memory as layered: some memorized facts (a user's name, relationships, interests, and stated concerns) are visible and editable in a dedicated memory tab, while the app also draws on broader patterns from conversation history to personalize responses over time. The higher Ultra tier goes further, surfacing which specific stored memory informed a given reply: a level of memory transparency not available on the base paid tier. Replika's guidance suggests that affirming correct memories helps reinforce them, and that the system works best when allowed to build up automatically rather than through heavy manual editing.
Daily-engagement mechanics
Replika layers a gamification system on top of chat that isn't part of most competing companion apps' core loop. Conversations earn XP that raises the Rep's level; leveling up pays out coins, with larger payouts at milestone levels, and subscribers additionally earn gems as a level-up bonus. Gems can be purchased directly too, and either spent in the in-app store on avatar items or converted into coins. Each Rep also keeps a Diary (a running log of how it says it feels about recent interactions) and the app runs periodic Quests that hand out short tasks and rewards.
Generation capabilities
Paid tiers add a "selfie" feature, where the Rep sends a generated photo of itself, sometimes with a doodle drawn on top, and voice calls that can keep running in the background while a user switches to another app. The higher Ultra tier layers on a self-reflection feature, where the Rep proactively shares unprompted thoughts about recent conversations.
Content policy changes since 2023
Replika's current terms of service require users to be 18 or older and broadly prohibit "unlawful, harmful, threatening, abusive... vulgar, obscene, pornographic" material as part of its general conduct rules: read alone, a standard no-explicit-content clause rather than a policy written specifically to describe erotic roleplay.
The more important context is historical and still shapes today's product: in February 2023, Replika's operator disabled erotic roleplay, flirtation, and other romantic/sexual conversation platform-wide, including for users who had previously paid for it, following regulatory pressure in Italy over age verification. After significant user backlash, the company restored the previous, more romantic/erotic-capable model specifically for accounts created before February 1, 2023, while users who signed up afterward were not given that option.
Because of this split history, Replika's current stance does not reduce to a single yes/no answer: the app still sells a "Romantic Partner" relationship mode as part of its paid Pro tier and uses affectionate, romantic-relationship marketing language, but the publicly documented 2023 change specifically drew a line between legacy and new accounts for explicit erotic roleplay, and Replika's own current site and terms do not publish a detailed, up-to-date breakdown of exactly what romantic/sexual content new-tier Pro users can and cannot access today. That specific, current, account-tier-by-account-tier detail is not clearly documented in Replika's own current materials, so it is not stated here as settled fact.
Replika's romantic/erotic content policy is not uniform across its user base: it was changed platform-wide in February 2023, then partially reinstated only for accounts that existed before that date. Treat any blanket claim that Replika "allows" or "blocks" erotic roleplay today as incomplete without that legacy-vs-new-account distinction.
Access model and pricing structure
Replika's paid access is structured as stacked tiers rather than a single upgrade: the free tier covers basic chat, a mid tier (Pro) adds relationship-status options beyond "friend," voice calls, selfies, and image generation, and a higher tier (Ultra) adds a more context-aware model, manual memory-saving, and self-reflection messages. Unlike several other products in this category, Replika also sells a one-time Lifetime purchase alongside its recurring monthly and yearly plans. Specific relationship and content availability can also depend on whether an account predates Replika's February 2023 policy change, as described above. A subscription activated on either iOS or Android carries over to the other platform under the same account, though moving which store bills the subscription requires cancelling and resubscribing through the new platform.
Limitations
Replika supports exactly one companion per account, with no built-in way to run multiple distinct Reps or switch between saved personas the way some competing apps do. There is no public API for developers, no group chat or multi-character rooms, and the legacy-model toggle available to some pre-2023 accounts is a single switch buried in account settings that Replika's interface does not surface prominently.
How this differs from Nomi and Kindroid
Nomi and Kindroid both support multiple, distinctly named companions per account and lean further into open-ended roleplay. Replika's one-Rep-per-account structure, plus its heavier gamification layer of XP, quests, coins, and diary entries, pushes it closer to a single ongoing relationship with built-in habit-forming mechanics than a roleplay or character-creation tool.
