What does Summarize This do?

Surely you can guess what ‘Summarize This’ does? Summarize This is an AI-summariser tool that helps you summarise Text, PDF, YouTube videos and Tweets for free.

It’s an extremely easy to use app, that will save you so much time! It’s a win-win. Before you get started, there are a few things to be aware of. To use Summarize This, it requires an OpenAI API key, so make sure you already have an OpenAI account, and fetch your API key from there. Another thing to keep in mind is that Summarize This don’t just have a website, they also have an iOS app, allowing you to summarise what you need to summarise, anywhere! But, the app does comes at a cost. The Summarize This app will set you back £2.99 a week or £8.99 a month.

Over 1,000 people have now used Summarize This. So, I was super excited to give it a whirl. I decided to test out the website. I had my PDF at the ready, my YouTube video on standby and my Twitter Thread chosen, I wanted to summarise EVERYTHING. Unfortunately, it wasn’t as easy as it was made out to be. I added my text to the summariser, along with with my OpenAI key, clicked ‘✨Summarize’ and waited and waited and waited…

I never received a summary. So I tried summarising my YouTube video, and then my Twitter Threads, no luck. It would be great if the Summarize This team included helpful notifications, to help you understand this process a little more. Was I doing something wrong? Was the platform facing troubles? There was no answer.

After hundreds of tries, the tool finally summarised my text! I got there in the end, but I didn’t feel like I had saved any time. The quality of the summary was ok. I did run through it and felt like some important things were missing. Remember to take all AI summarisation tools with a pinch of salt!

We Love:

  • There’s no learning curve - just get started.
  • Available online and iOS app
  • Simple to use interface

We Hate:

  • Very buggy, you need to be patient!
  • Still a lot to be improved on the product

Our Verdict on Summarize This

Using Summarize This was easy, when it worked. I found myself getting very impatient. For me, the time it took to finally generate a summary and the quality of the summary just wasn’t worth it. It was a real shame! In my opinion, there are better AI-summariser tools available.

Compared Alternatives

  • ChatPDF - As well as summarising documents, ChatPDF can also translate documents into any language! If you’re looking to summarise a range of different files and not just PDFs, stick with Summarize This.
  • Perplexity - Has a Chrome extension, so you can summarise online resources in a flash. If you’re wanting to take advantage of the Perplexity Pro plan, keep in mind it’s a lot more expensive than Summarize This pro plan. Perplexity will set you back $20/month.
