AirThumb is a Chrome extension designed to enhance the Airbnb browsing experience by allowing users to rate listings with a simple thumbs up or down. This intuitive tool displays icons on each listing, enabling users to quickly indicate their preferences and easily recall which properties they liked or disliked.

In addition to the rating feature, AirThumb includes a text input field for users to jot down notes about each listing. This functionality provides a personalized touch, helping users keep track of their thoughts and impressions. It is important to note that all ratings and notes are stored locally on the user's computer, meaning data will not carry over if the extension is reinstalled or if the user changes devices.
