Therefore, this guide will uncover all about SciSummary and evaluate its performance efficiency. So, let's get started with our comprehensive SciSummary review.

Part 1. An Overview About SciSummary

SciSummary is one of the many AI summarizers you can use today to intelligently summarize articles and consume content faster.

What Is SciSummary?

SciSummary or Science Summary is an online AI summarizer that intends to make the digestion of scientific articles easier. It leverages GPT 3.5 and GPT 4.0 to summarize articles and quickly grasp key points without reading the full text.

With SciSummary, all you have to do is send/upload the documents and get a thorough summary of all parts within minutes. You can also customize how you want to summarize, i.e., complete summary, page-based summary, etc. On top of that, you can use its AI chat assistant to ask questions about the article.

Overall, SciSummary is a handy tool for scientists and students who don't have time to read lengthy scientific articles. According to SciSummary, it has summarized over 750,000 papers for over 330,000 users.


AI summarizers are incredibly useful for work purposes. Moreover, there exist several robust summarization tools capable of summarizing entire documents, including articles. UPDF stands out among these tools, as it can efficiently summarize extensive PDFs exceeding 1000 pages in mere seconds. With the added advantage of uploading up to 3 files for free, users can promptly obtain summaries and significantly enhance productivity. Take advantage of this opportunity by downloading the tool and registering for a free trial today.

Is SciSummary Free?

No, SciSummary is not entirely free. It does provide a free plan but with the following limits:

Cons of SciSummary:

  • 10,000 words per month summarization
  • 5 documents indexed for semantic search
  • 200,000 words summarization for the first month

Simply put, you can use SciSummary for free if your monthly word summarization is up to 10,000 words. For a higher word count, you can subscribe to one of its below plans:

  • 1M Words: $4.99/month (1,000,000 words summarization per month).
  • 2M Words: $8.99/month (2,000,000 words summarization per month).
  • Lifetime: $299.99/one-time (10,000,000 words summarization per month).

Besides the above plans, SciSummary also supports document-based payment. You can pay per document, which can mostly cost less than $2.

How does SciSummary work?

SciSummary is a web-based scientific article summarizer. To use it, you first have to register an account.

Once registered, you can get a summary in multiple ways, i.e., you can send an email, upload a PDF file, add an article link, or insert raw text.

Upon uploading the PDF file of a scientific article (article from IEEE Access), you get a bunch of summarization options. There are different summary modes to choose from, such as summarize by section, summarize key points, summarize with area to focus, and much more.

Secondly, you can specify the summary length, language, and pages. Once you have specified the settings, click "Request New Summary".

Now, you have to wait for a few minutes until SciSummary completes the summary. Once done, you can read out the summary it generated.

Looking at the summary quality, SciSummary seems to do the job diligently. It has managed to provide a quality summary of the whole article.

At the bottom of the window, you will see the "Expand Upon" feature that allows you to expand the summary upon any specific term.

SciSummary also has a chat feature that allows you to have human-like chats about article content and clarify doubts. However, this feature is only accessible if you subscribe for $4.99/month.

Besides that, we have seen that the 10k word limit in the free plan is very limited. Most scientific articles are beyond the 10k word limit range. For instance, the article we summarized above was a 22.38k word article. This means that you can only summarize 1-2 articles in the free plan.

User Reviews of SciSummary

SciSummary has received mixed reviews from users. Some of the positive and negative reviews are as follows:

Positive Reviews

  • Great productivity tool for engineers, scientists to stay ahead of the field. Great work!
  • I'm still testing the tool yet it looks very promising. I tested it with a 5.5k words Academic text that I had previously red. I tested the Key points feature, it does work!

Negative Reviews

  • Good tool but be mindful: if you want it to expand on subjects that aren't covered in the inputed article, it can derail the summary and make some genuine leaps in logic, just to give the result you asked. Careful on your Expand prompts

SciSummary is a great tool, but its subscription-locked chat feature and troubling expand-on feature can compromise the experience. In contrast, UPDF is another similar AI summarizer, but it has no such limits. It can summarize in any way you want and provide access to the chat feature for free for limited PDFs.

So, if you want to get a SciSummary similar experience without limits, then download UPDF and start using it for scientific article summaries.

From the above SciSummary review, we can say that the tool is definitely worth trying to summarize scientific articles. Its different summary modes, expand-on features, and other options make it a handy tool for summarizing articles. You can easily summarize lengthy articles and get brief or comprehensive summaries quickly.

The downsides of SciSummary are its 10K words free limit, subscription-locked chat feature,  and inefficient expand upon feature. Besides that, there is no option to annotate the article for enhanced reading. So, if you want to eradicate all its limits, then you should opt for UPDF – a more powerful AI summarizer.
