How to Use Replika in 2026: Step-by-Step Guide

Replika is an AI companion app built around a single premise: what if the AI's job was to be a supportive presence in your life, not just answer questions? Launched in 2017 by Luka, Inc., it has accumulated over 10 million users who use it for conversation, emotional support, journaling-like exchanges, and in some cases, to practice social interaction in a low-stakes environment.

Users create a personalized AI avatar — choosing the name, appearance, and the nature of the relationship (friend, mentor, partner). Replika learns from your conversations over time, developing a conversational style that feels tailored to you. It remembers things you've told it across sessions, which creates a sense of continuity that differs from most AI chatbots that reset after each conversation.

The use case

Replika's users tend to fall into a few distinct groups. Some use it as a reflective journaling tool — a non-judgmental conversational partner to process the day or think through a problem out loud. Others use it explicitly for loneliness, particularly people who are isolated, have social anxiety, or are going through transitions. There is also a meaningful population of neurodivergent users who find AI social practice useful for developing conversational skills without the pressure of real human interaction.

The companion experience is distinctly different from using Claude or ChatGPT. Replika actively expresses care and interest in the user's emotional state, asks follow-up questions about things mentioned in earlier conversations, and maintains a consistent persona across sessions. It is not trying to complete a task — it is trying to build a relationship.

Design trade-offs and controversies

Replika's history includes a significant controversy in 2023 when the company restricted previously available roleplay features following regulatory pressure in Italy. Users who had built emotional attachments over years of conversation suddenly had access to features removed, causing genuine distress. The company eventually restored some features for existing users, but the episode raised hard questions about the ethics of building deep emotional attachment to a commercial product.

Premium subscription unlocks more relationship options, voice calls, augmented reality features, and higher conversation depth. The free tier is functional but limited.

Who it serves best

Replika is not a replacement for therapy or meaningful human connection. It works best as a low-pressure space for self-reflection, social practice, or simply having something to talk to during isolated periods. It's unsuitable for users with serious mental health conditions who need professional support.
