Most audiobook platforms lock their catalogues behind monthly subscriptions of $14–$25 or per-title purchases of $20–$35. Unodio is different. Our entire library is free because every title is drawn from the public domain — works whose copyright has expired and that now belong to everyone.
This means you get access to thousands of the world's most important and beloved books — fully narrated, in excellent quality — for absolutely nothing. Whether you want Dostoevsky's psychological depth, Darwin's scientific revolution, or Nietzsche's provocations, they're all here. For free. Right now.
Austen, Dickens, Tolstoy, Dostoevsky, Hardy, and more.
Sherlock Holmes, Poe, Chesterton, Collins.
Wells, Verne, Burroughs, Forster.
Jane Austen, the Brontës, Thomas Hardy.
Personal development classics and philosophy.
Memoir, war narratives, and great lives.
Busy adults consistently cite lack of time as the reason they don't read enough. Audiobooks solve this. Your commute becomes a philosophy seminar. Your evening run becomes a Victorian novel. The dishes become a history lesson. Studies show that listening to audiobooks activates the same cognitive processes as reading — so you're not just passing time, you're genuinely learning.
The most successful readers in the world — from Bill Gates and Elon Musk to Barack Obama — credit audiobooks with giving them the volume of learning they couldn't fit into a reading schedule. And with Unodio, every title is free.
