Pinterest is a social media platform where users can save, organize and share images related to their interests. It is an online pinboard that allows users to collect images of things they like, and then organize them into boards.

Users can create their own boards or join existing ones. They can also follow other users and their boards, which helps to keep track of what they're interested in. Pinterest also has a search function, so users can easily find images related to their interests.

In addition to being a platform for saving images, Pinterest is also used for promoting products and services. Users can create boards for specific products or services, and other users can follow these boards to see what others are saying about the product or service. This can help to build trust and credibility with potential customers.
