I had a great experience working with…

I had a great experience working with Sumizeit! From the very beginning, their team was professional, responsive, and genuinely interested in making sure my needs were met. They communicated clearly and made the whole process smooth and hassle-free. I’d definitely recommend them to anyone looking for a company that truly cares about their clients!

Great help to the busy

I always felt busy but still wanting to keep up with the book discussion in my friend group. This was a great supplement to help me keep reading the books I find fun while keeping up with important books.

6 month review

I've been using Sumizeit for about half a year now, and I can honestly rate it 5 stars. For someone constantly on the go, this is the app for you. It's saved me so much time and this is coming from someone who has read well over 200 books. With detailed summaries and how consistent it's been within the past 6 months, Sumizeit should be your goto if you wanna gain quick knowledge on certain readings.

I love this app

I love this app. It makes my life so much easier. I have ADHD so reading books can be hard. I find the 15 minute summaries to be very useful and comprehensive. I feel like I get a good understanding of the book. I like the video book summaries. Very fun to watch and makes the experience even much better. I would definitely recommend this app.

I love this website

I love this website. Instead of scrolling social media, I find myself learning a lot. I use it everyday. I recommend this app for anyone who is too busy and wants to get up to speed with their favorite books. It's also a great way to decide whether a book is for you.

Very fun app to use

Very fun app to use. Life changing. Sumizeit makes learning fun. I read and listen to the summaries on my commute each morning. Good selection of book summaries that you can read or listen to in various genres. Please add more science books. I’ve learned so much using sumizeit. If you want to grow, use this app.

Service Abysmal

They inundated my email with a $60 lifetime membership so I finally but. BIG mistake!! My account will not update from free to lifetime membership so I reached out and did what was recommended…3 TIMES before I finally decided to ask for a refund. This was ONE day after signing up for the lifetime membership. They refused saying they don’t offer any refunds. Few red flags about this company: 1) I should’ve known $60 for lifetime membership was too good to be true - they’re deceptive! 2) they keep asking the customer to prove, repeatedly, even after sending them screenshots and doing what is expected, that there really is an issue. All they had to do is wipe my account and upgrade it themselves on the back end, but no dice. And 3) nothing says “we’re cheap and don’t believe in our own products” more than saying “We don’t offer refunds.”

Excellent audiobooks

I started using this app during the pandemic and homestay in early 2020. I was always sending to the customer service to add features and they did the all, like "send to Kindle" The app is excellent, but we still wait for more content and titles inside.
