Project Description

In 2022, OpenAI launched a chatbot, ChatGPT, that took the internet by storm. ChatGPT is a large language model (LLM) based on artificial intelligence that allows us to have human-like conversations. The language model can answer questions and assist us with tasks, such as composing emails, essays, and code. This AI model has been a game changer for the industry, because it allows us to have better interactions and get high-quality responses.

In this project, we will create a writing assistance tool. When we write a piece of text, we can use OpenAI’s API to rephrase, improve, and even change the tone of the text written.
