There’s a lot of reasons you might need a book summary. Maybe you don’t have the time to get through the books on your “want to read” list. Maybe you need to write some book notes for an article you’re working on. Maybe you just want to figure out if you want to read a full book.

Either way, it can be incredibly time-consuming to read through a whole book to find what you need, which is where book summary websites become a great option.

In this article, we’re going to dive into five different options. Most sites cover different types of books or have different uses, so you should be able to find the one you need.

This guide to the best book summary websites covers:

  1. What are book summaries?
  2. Blinkist
  3. getAbstract
  4. SparkNotes
  5. Instaread
  6. Optimize

What are book summaries?

Book summaries are pretty much exactly what they sound like — a summary of a book. Some summaries are incredibly in-depth and give you a ton of details. Others are shorter and give you main bullet points. Which one you pick will depend on what you need the summary for, but just know both are available.

If you’re a person who loves the nitty gritty details in some books, book summaries might not work for you. Most summaries skip over the stories that accompany most of the points the author is trying to make. However, if you love just being able to understand the main points and don’t mind losing some of the accompanying stories, these are exactly what you need.

Each book summary also depends on the person or company creating the summaries, as different people might find some parts more important than others.


Book Summary Websites - Blinkist

Blinkist is one of the more well-known book summary websites. It helps you get through books within fifteen minutes instead of the usual hours (or days) it takes to get through a book. Currently, there are over 5,000 books you have access to inside of Blinkist to learn. At the time of writing this, there is currently a free plan which only lets you access one summary per day, but depending on your schedule that might be a great option.

The main premise behind Blinkist is to use your blocks of time where you’re doing something mindless, such as commuting or waiting in line at a store, to learn great takeaways from some of the most popular books out there. You can download the audio versions of any of the book summaries so you can listen to them while you travel or are offline.
