What is Replika Chatbot?

The company built this to act as a friend to a person. The motto is this friend will be there for you, talk, listen, and without judgment 24X7.

Backstory of Replika Chatbot

Backstory of Replika Chatbot

Replika was created by a San Francisco-based startup, Luka. Luka's founder Eugenia Kuyda suffered a terrible loss, and while reeling from the pain, she envisioned the Replika chatbot. Eugenia was a magazine editor in Russia in 2015 and had a friend Roman Mazurenko.

They both moved to San Francisco and founded their startups. Roman and Eugenia became close friends, but unfortunately, she lost him in a car crash. Luka's original idea was to create a chatbot that gave restaurant recommendations.

In the aftermath of Roman's death, Eugenia started reading texts and conversations with Roman. She then had the idea to put his messages through a neural network and create an A. I based version of him. This concept has evolved into the app Replika. 

Some statistics about Replika Chatbot

  1. Replika chatbot has formed a community of more than 10 million users who interact with their Replikas daily. 
  2. This app ranks in the top fifty (#33) in the health and fitness category. 
  3. The average app rating is 4.1 based on more than four hundred thousand reviews.
  4. 85% of Replika users find it helpful to ease their anxiety and stress. Simply talking with the app has helped a plethora of users.
  5. A hundred 100 million messages are sent between users and their Replikas weekly.

How does Replika chatbot work?

Let's figure out this enigma:-

  1. The main idea is to put all interactions(messages, pictures, etc.) between users and Replikas through an A. I algorithm. This will create a neural network that will constantly evolve and improve the chatbot's answers over time. 
  2. The app's purpose is to create an interactive and engaging conversation through various models and artificial intelligence algorithms. 
  3. Once a user starts a conversation, the models start working. They ensure that the responses are empathetic and soothing to the user.

How does Replika Chatbot produce human-like answers?

  1. Replika chatbot uses a dialogue engine that constitutes various models and algorithms to create the most humanly possible conversations possible.
  2. It follows a three-pronged approach. It generates answers through two models and filters them with another model to select the best response. The responses continuously evolve as user feedback is a vital part of the app. 
  3. Retrieval dialogue - this model determines responses based on a prefixed algorithm and predicts what it thinks is the best. It is one of the models that analyzes and sorts through the data flowing through the app's servers. 
  4. Generative - this model generates responses from scratch. An AI app is not truly artificial until it creates things without human support. This is where this model applies its magic. The responses generated are always unique and new.
  5. Reranking- this model is the filter between the retrieval and generative model. It is the last stage before a response is delivered. Once input is received from both predefined and unique phrases, it delivers the verdict on which one to send out. 
  6.  Hence, By a combination of these three models. A smooth dialogue between the user and their Replika is ensured.
