Book Randomizer – Pick Your Next Read from Your Shelf

A Book Randomizer helps you pick your next read by randomly selecting a book from your personal shelf. It's perfect for overcoming decision paralysis when you have many unread books and can't decide which one to start next. Simply build your digital shelf and let the randomizer make the choice for you.

The tool uses a pseudo-random algorithm to pick a book from your shelf. You can customize the selection by applying filters — exclude books you've already read, skip recently picked titles, or limit the pool to specific genres. The animated shuffling effect adds a fun, suspenseful moment before revealing your next read.

Yes, your bookshelf and recent picks are stored locally in your browser using localStorage. This means your data persists across sessions on the same device and browser. No data is ever sent to any server. If you clear your browser's local storage, your shelf will be reset. For important collections, consider keeping a backup list.

Absolutely! Use the "Batch Import" button to paste a list of books. Format each line as "Title - Author" (e.g., "The Hobbit - J.R.R. Tolkien"). All imported books will be added to your shelf with a random cover color and default "Want to Read" status. You can also load our curated sample books to see the tool in action.

Enable the "Exclude recent picks" option in Settings. You can choose to skip the last 3, 5, or 10 randomly selected books. This ensures variety in your reading recommendations. The recent picks history is displayed below the randomizer for easy reference. You can also mark books as "Read" to exclude them permanently from the selection pool.

The tool supports a wide range of genres including Fiction, Non-Fiction, Mystery, Sci-Fi, Fantasy, Romance, Biography, Horror, Thriller, History, and Self-Help. You can assign a genre to each book when adding it to your shelf, and use genre filters in Settings to narrow down your random selection to specific categories you're in the mood for.
