The problem Tagonizer 2.0 solves

Everyone Loves Online Shopping🛒. But when it comes to selecting a product, we are dependent on the true reviews and actual images of the product put up by past users.
On famous E-Commerce websites like Amazon, Flipkart, AJio, Myntra etc, these reviews, tags and user Images can be misleading, incorrect, paid or simply useless😕 .

The Main Problem can be concluded in the following points :

• Useless or Meaningless Auto-Generated Tags 🏷️
• Reviews not classified as positive👍 or negative 👎
• Tags not classified as positive👍 or negative 👎
• Repeated Tags 🏷️🤔
• Paid Review Tags that don't reflect sentiments of Customers 😢
• Misleading Images that don't match the actual product ❓
• New Buyer or Potential customer had to go through hundreds of reviews, tags and images to judge the product properly 😳

How Can Users Use our Extension

• Just install the extension and visit any product on Amazon.in
• Open up the Tagonizer Chrome Extension, and Voila!
• Use Tags, Reviews and Images feature to judge a product properly and buy it if you like it
• Tagonizer, can save you more than 10 min/product at no cost. 😃

Challenges we ran into

Challenges 🏋️ and Hurdles🚧 are the most important part of any journey, they make us strong by continuously testing our enthusiasm and patience. We too faced many Challenges, while developing Tagonizer Extension, some of them are:

• _Code Collaboration_🤝 : Since we are in the middle of a Pandemic, It was hard to collaborate in-person to discuss ideas and develop, hence we had to use tools like Google Meet, Discord, GitHub, UseTogether etc
• _Errors and Bugs_🐛 : The Destiny of Every Developer ever, Error and Bugs are our constant companion, and we love to eradicate them, thanks to Stackoverflow, the trustworthy friend
• Huge Data to Test 📊 : We had the entire Amazon website, in front of us and the challenge was to efficiently fetch the customer reviews, without affecting the site/ extension performance
• Efficient UI/UX 🖥️ : Users are our 1st Priority, every bit of attention is paid to the UI of the extension, which was a real challenge to achieve
• _Production Errors_⚠️: Production Testing is always different than local testing, we too, faced such issues and the last-minute Debugging was really intense
• _Breaking Bad_💥: In Production too, our Extension and Backend API broke a few times, due to load, end sequences or unseen bugs, but all of them were corrected.
