Position sync

Pick up where you left off. Literally.

You're reading on the couch and it's time to drive. Get in the car, press play — the audiobook starts at the sentence you just finished. Open your e-reader before bed and you're on the right page. No scrubbing, no searching, no "wait, did I already read this?"

Other stores sell you the same book twice and still lose your place between formats. Arcus treats the book as one thing, because to you, it is.

One library

Stop buying the same book twice.

Want a title in ebook and audio today? You pay twice, often at two different stores, and manage two libraries. Arcus sells the bundle: one purchase, one library entry, both formats included.

Your shelf is your shelf — on your phone, your tablet, your laptop, and in your car.

The companion

A book you can talk to.

Every Arcus title ships with an AI companion that has actually read the book — and knows exactly where you are in it.

  • Ask the book anything. "Who is this character again?" Answers that never spoil ahead of your position.
  • Podcast-style discussions. Generate a two-voice conversation about the chapters you've finished.
  • Study guides on demand. Summaries and recaps keyed to exactly how far you've gotten.

Be there when the doors open.

We're building Arcus right now. Join the waitlist and you'll get first access — and launch pricing on the first titles.

No spam. One email when it's your turn.
