Page Freshness Checker is a Chrome extension designed to help users quickly determine the freshness of webpage content. This tool automatically detects and displays the last updated or published dates from webpage metadata and JSON-LD, presenting a clear banner at the top of the page with a color-coded freshness status. The indicators range from green for fresh content (last updated within three months) to red for outdated information (over six months). This functionality is particularly beneficial for researchers, content creators, and professionals who need to ensure the reliability of their sources.

The extension is lightweight, operates instantly on most websites, and includes a user-friendly close button to dismiss the banner when necessary. By providing instant verification of content freshness, Page Freshness Checker helps users avoid outdated information, making it an essential tool for anyone engaged in research or content curation. With its straightforward interface and efficient performance, this add-on enhances browsing experience by keeping users informed about the reliability of the information they encounter.
