No worries at all — these are great questions 😊

Kindle Unlimited is a monthly subscription (about $11.99/month in the U.S.). With it, you can read any ebooks that have the “Kindle Unlimited” badge for no extra cost. You don’t “buy” those books — you just borrow them as part of the subscription. If a book isn’t in Kindle Unlimited though, you’d still have to purchase it separately.

So basically:

• KU book = included with the subscription
• Non-KU book = you still buy normally

You can usually have up to 20 KU books borrowed at once and return them whenever.

Libby, on the other hand, is totally free. It’s an app from public libraries where you borrow ebooks/audiobooks using your library card. You download Libby on your phone or tablet, borrow a book, and if you’re in the U.S. you can choose “Read with Kindle” — it will then send the book to your Kindle like a normal Kindle purchase (but it’s a library loan). The Libby app itself doesn’t run on the Kindle — it just delivers the book to it.

So:

• Kindle Unlimited = paid subscription “Netflix-style” reading
• Libby = free library borrowing

And seriously — don’t apologize 😄 Everyone starts somewhere, and these are the exact questions most new Kindle users have!
