In the digital culture, virtual assistants and chatbots are increasingly getting popular for providing support on behalf of many industries and businesses.

As people are increasingly moving towards more critical roles in businesses, the support and assistance are losing their functioning density, Thus, it was the right time to introduce AI-powered chatbots and virtual assistants into the world.

Though robots, chatbots, and any other vessel using artificial intelligence can replace emotional relationships with virtual emotional support for humans, it has always been debatable.

Hence, an AI-based companion app like Replika was introduced, not as just a chatbot but as a companion, a friend, or someone you can talk to for getting emotional support.

What is Replika?

There are many virtual assistant apps in the market but keeping up with Replika is not easy. It uses chatbots as a friend or companion with the ability to perceive and evaluating human emotions.

It was created to fill the void left by creator’s best friend and became an awe-inspiring story, providing support to people in all circumstances.

An app like Replika utilizes AI to keep the conversation going while analyzing your emotions to give the best-fitted replies. It can also sense the environment of your mood and reply back accordingly.

You can customize it to replicate the behaviour of any person, dead or alive. And you can do that by submitting all their personal details and texts.

How do Replika works?

Replika utilizes GPT-3, an autoregression model for language, creates human-like texts using deep learning.

This means that it takes all the previous conversations into consideration to learn more about the host; it is about to take over.

It uses a neural network architecture with almost the same layout as our brain to take inputs similar to logic and conditional statements. And nodes with each end working as a signalling channel for the network.

In simple words, it increasingly gets better at performing as you keep using it.

Now, let’s move forward and learn more about the process of creating it.
