It also lets you talk to your content, asking questions, getting summaries, or taking quizzes on what you just heard. Beyond reading, Speechify offers voice typing so you can write by speaking, and it can turn any document into a short AI podcast.

Everything you save syncs across your phone, computer, and browser, so you can start listening on one device and pick up right where you left off on another.
