pik1989/Sentiment-Analysis — reverse-engineered prompt

Build me a simple sentiment analysis app for Amazon Alexa customer reviews. I want a local web page where someone can paste a review, click a button, and immediately see whether the review sounds positive or negative.

Use the existing review data to train a basic machine learning model, save the model, and connect it to a small Flask app with a clean form and results page. Keep the interface simple and beginner friendly, since this is more like a demo project than a full product. Include a notebook or script that shows the data exploration and model training, and make sure the app can load the saved model without retraining every time.

Please also make the project easy to run locally, with clear setup steps, a requirements file, and a command to start the app on localhost. Look up current docs online if you need to.
