Notes

• This application uses web scraping to retrieve product information from Amazon websites. As a result, it may stop working if Amazon changes its website structure or implements measures to prevent web scraping.
• The application does not store any user information or share it with third parties. It only saves the search history locally in the browser.
• No AI was harm during the creation of the project.
