Performance Efficiency of TLDR This Article Summarizer

Now that we know the main functionalities of TLDR This article summarizer, let's do some performance tests and analyze its efficiency.

We are using an online article on a cybersecurity topic to ask TLDR This to summarize. First, we asked it to summarize the article by highlighting "key sentences" and doing a "detailed/section-wise" summary.

tldr this detailed summary

The summary it provided was very detailed, almost like reading the original article. It barely reduced sentences. So, we decided to ask again for a "Key Sentences" summary, but this time "Short/Concise".

tldr this key sentences

The summary this time was concise but was not good quality-wise. Some sentences did not make sense, and it seemed like it randomly picked a few sentences from the article.

Now, we decided to use its AI summary feature. For the same article, we asked TLDR This to provide an "AI (human-like) Summary" in the "Short/Concise" form.

tldr this short

The summary became much more sensible. It could now explain the article's main points very briefly. Since it was very brief, we asked it again to provide an "AI (human-like) Summary" in the "Detailed/Section-wise" form.

tldr this ai summary

This time the summary was detailed and provided a quick overview of the whole article. However, we noticed that it was still copy-pasting article content despite claiming to provide an AI-powered summary.

Overall, after conducting multiple tests on TLDR This, we can say that it can reduce the time to read articles if you summarize articles through its AI summary option. However, we believe that summary quality could have been improved, and more options should be present to customize the summary results, like short bullet points, etc. These features are easily accessible with UPDF AI.
