I. Q. Notes lets you continue your reading where you left off in the Ex-IQ app, and allows you to use voice to add highlights, tags and annotations which you can refer to later on. Whilst listening to a book, you can say the following things; Alexa, ask I. Q. notes to Highlight This; Alexa, ask I. Q. notes to Add a Tag; or Alexa, ask I. Q. notes to Make a Note.
