In this project, you will develop a browser extension that uses sentiment analysis to analyze the tweets on your screen and display the results in a pie chart. This will provide a visual representation of the sentiment of the tweets, allowing you to quickly and easily understand the overall sentiment on the page. The extension will use Chart.js, a popular JavaScript library for creating charts, to create the pie chart. Additionally, you will use a pre-trained machine learning model to perform sentiment analysis on the text of the tweets. This project will provide you with a hands-on opportunity to learn about machine learning in practice, as well as how to create browser extensions and use Chart.js.

Here's a quick demo of the extension in action after searching for Spotify!

*A credit card is required but you won't be charged until you reach a certain usage.

You won't need much to get started with this guided project; just an IBMid which you can quickly create from here. You'll be provided with an IBM Skills Network Labs environment with many things pre-installed (e.g. Docker) to save you the hassle of setting everything up. Also note that this platform works best with current versions of Chrome, Edge, Firefox, Internet Explorer, or Safari.

If you would like to deploy your Sentiment analysis model to IBM Cloud Code Engine which is an optional step. In that case, you'll need to provide a credit card to your IBM Cloud account associated with your IBMid to allow the Code Engine commands to run. But you won't be charged until you reach a certain usage.

If you would like to deploy the extension to the Firefox Add-ons Developer Hub for others to use, you will need to be registered as a Developer on their Hub. This is entirely optional and you are able to use your created extension locally without being registered.

If you would like to deploy the extension to the Chrome Web Store for others to use, you will need to be registered as a Chrome Web Store Developer. This is entirely optional and you are able to use your created extension locally without being registered.
