"Exact" is far from accurate. I just did a side-by-side comparison. To name only two obvious differences:
A. At the top level, Perplexity has a "Discover" tab [1] -- not titled "News". That leads to a AAF page with the endless-scroll anti-pattern (see [2] [3] for other examples). Kagi News [4] presents a short list of ~7ish items without images.
B. At the detail-page level, Kagi organizes their content differently (with more detail, including "sources", "highlights", "perspectives", "historical background", and "quick questions"). Perplexity only has content with sources and "discover more". You can verify for yourself.
