I've tried to find the exact articles via WoS, Google, or Scopus. Despite using a very advised and complicated search query, it was just a waste of time. Perplexity didn't help either. The Jenni AI, which may add useful links when generating text, finds nothing but trash. SciScape gave exactly what I needed from the first query! A couple of fresh relative articles with very exact topics!

I was just trying to get a quick graph showing population evolution over the last 30 years, didn’t have the dataset ready, so I was hoping the tool could auto-fill something reasonable. But it literally gave me three values. Three?? For 30 years?? What kind of trend can I possibly see with that? If the tool offers to research the data, it should at least offer a full timeline. And when I pasted the data I found, it created a literally bar chart???

tested it on a few neighborhoods. the interface is so stripped down it almost feels unfinished, quick to load but u might hunt for extra fillers. the data look on point, yet they dont dive deep into data sources to explain. overall accuracy feeks solid and the map is smooth, just wish it talked more about the results.
