This app analyzes any page from a book and instantly determines its reading level using advanced AI technology. Simply point your camera at a page of text, and get comprehensive reading level information including age range, grade level, English Lexile score, and foreign language reading levels. Unlike barcode scanning apps that require the book's ISBN and internet lookup, this app analyzes the actual text content. This means it works with: • Library books without visible barcodes • Old books or books with damaged covers • Photocopied pages or digital displays • Books without ISBN numbers • Foreign language books Our AI analyzes text complexity, vocabulary difficulty, sentence structure, and content sophistication to provide accurate reading levels. The analysis happens instantly with results in seconds. Get three standardized reading level formats: • Age Range (e.g., 8-10 years) • Grade Level (3rd grade) • Language Specific Reading Level (Lexile, HSK, CEFR, etc.) Need Help? Want to send feedback?
