Spruce is a powerful tool for exploring famous quotes related to your writing.
Spruce is a search engine for finding inspiring sentences. Tell Spruce about something you've read or written and it will find quotations or lyrics that are related to the subject matter, sometimes in surprising and subtle ways. Spruce gives you a diverse set of perspectives on your text that you can cite in your work or reflect upon in your brainstorming.
Spruce is a free service from Datamuse, created by Jonah Fried and Doug Beeferman.
