Nightingale is a free Chrome extension developed by Nightingale. It falls under the category of Browsers and is specifically listed as an Add-ons & Tools subcategory.

The Nightingale extension is designed for individuals who have an interest in the poetry of John Keats. As users browse the web, Nightingale actively searches for semantic, syntactic, and prosodic connections between Keats's poetry and the content on the webpage. When a connection is found, certain text on the page will glow, indicating a potential echo from Keats's work. By hovering over the glowing text, a pop-up will appear, displaying the corresponding quotation from Keats. Clicking on the pop-up will open a new window with the original poem.

Nightingale also keeps track of the Keatsian quotes that users have encountered recently, ensuring that fresh and diverse quotes are presented. Additionally, if a user spends at least ten seconds reading a quote, Nightingale will provide a break from pop-ups for several days.

Experience the beauty of Keats's poetry as you browse the web with Nightingale.
