You have a long article or report to skim, and TLDR This promises a one-click summary. It works well on straightforward news pieces, but it drops the context, numbers, and citations you need for research. Below is how to use it, where it lets you down, and a free way to summarize PDFs and reports while keeping the details.

What TLDR This Gets Wrong: Context, Citations, and Paywalls
The catch is that a short summary removes exactly what research needs: the exact numbers, the cited sources, and the nuances an argument depends on. On paywalled or complex PDFs, web summarizers often fail or return a summary you cannot trust.
So a one-click web summary is fine for a quick read, but not as evidence. When you summarize for work, school, or any decision, you want the tool to work on the original PDF and keep the source lines intact.
