What is Replika?
Replika is an AI companion app that holds ongoing, personal conversations by text or voice. It was created by Eugenia Kuyda and is run by Luka, Inc., and one 2026 review puts its user base above 40 million. It began as a personal project after the loss of a friend and has grown into one of the most recognised apps of its kind.
It works by pairing a language model tuned for empathetic conversation with a memory of what you tell it. Over time it refers back to earlier chats and adapts its tone to you.
Key Features
Replika’s key features are text chat and voice calls with one persistent AI companion, a customisable 3D avatar, a memory of what you share, selectable relationship modes, and AR and VR experiences.
- Text and voice chat: Talk to your companion at any time by message or by voice call. Replika’s help centre lists voice messaging and background calls among its Pro features.
- Custom 3D avatar: Choose the companion’s name, look and personality. Premium avatar customisation and premium voices with different accents are part of Pro.
- Memory: It stores details about you, such as the people, routines and plans you mention, and recalls them in later conversations.
- Relationship modes: Set it as a friend or mentor; other modes need Pro, including the romantic relationship status. The service is for adults aged 18 and over.
- Selfies and images: The companion sends selfies and reacts to photos you share, and the help centre lists image generation as a Pro feature.
- Wellbeing exercises: Guided activities cover stress and reflection. Replika’s terms state that it is not a healthcare provider and that its services are not mental health care.
- AR and VR: See the avatar in your room through augmented reality, with roleplay during voice and AR calls on Pro. A 2026 review also lists a Meta Quest version.
Pros
Replika’s main advantages are a companion that is available at any hour, free basic text chat, a persistent memory and personality, and a choice of text, voice and AR formats.
- Always available: Conversation is there whenever you open the app, without waiting or judgement, including late at night.
- Highly personal: It adapts to how you talk and refers back to details you have shared, so conversations continue from where they stopped.
- Several formats: Text, voice calls, AR and VR are offered, so you can type when you want quiet and talk when you do not.
- Free to start: Basic chat costs nothing, which lets you decide whether a companion app suits you before paying for Pro.
- Long-running service: Replika’s homepage counts more than 42 million users, and the company says it launched its companion about a decade ago.
- Plain terms: The terms of service set a minimum age of 18 and say directly that Replika is not medical care or a mental health service.
Cons
Replika’s main drawbacks are that it cannot replace professional mental health care, its maker has a data protection fine on record, voice and other features sit behind Pro, and heavy use can encourage dependency.
- Not a therapist: It cannot replace professional mental health care. Replika’s own terms make no guarantee of therapeutic benefit, so contact a qualified professional or a local helpline in serious distress.
- Privacy record: One 2026 review reports that Italy’s data protection authority fined its maker in 2025. You share personal thoughts with a commercial service, so limit sensitive details.
- Can be wrong: Reviewers note that it favours agreeable replies over accurate ones, and it is not built for facts, research or tasks.
- Dependency risk: Heavy use can crowd out human contact. Treat it as a supplement to real relationships, not a replacement for them.
- Key features are paid: Voice calls, premium voices, image generation and the romantic status need Pro, which reviews report at about $19.99 a month or $69.99 a year.
- Purchases are final: Replika’s terms say subscriptions renew automatically until cancelled and purchases are not refunded except where the law requires, such as the 14-day withdrawal right for EU residents.
