Nope. There is no reason to use perplexity.
Early 2023 - August 2026, I used their rudimentary LLM before making any major purchase – seems like they really dropped the ball by both locking out users (log-in requirements) and not exploiting their early-Top10-LLM status to leverage into corporate ad influencing (again, which is how I primarily informed my own purchases, until login requirement).
I run most of my LLM locally at this point, but it would be great to have perplexity be the autistic shopping tool it once was. Ce la vi
