Example use cases

“I just read that cryptocurrency's carbon footprint has decreased by 50% over the past five years. Can you fact-check that claim and show me the academic research backing it up?”

“I'm writing a report on the history of machine learning breakthroughs. Can you pull up a research timeline showing the key papers and discoveries that shaped the field?”
Validate health information online
“Someone told me that vitamin D deficiency is linked to seasonal depression. Can you verify if that's actually supported by peer-reviewed research and show me what the scientific consensus says?”
