Research stocks and update a watchlist in the browser

An investor uses Perplexity Comet to scan his watchlist, find Swiss companies hit by US tariffs, summarize Reddit and market commentary, and add stock picks to a Google Sheet.

What They Did

Using Perplexity Comet, an AI browser, the author asked in plain language for tasks across tabs. Comet went through his stock watchlist and listed Swiss companies hit by the US tariffs. It summarized a Goehring and Rozencwajg commentary and the top Reddit post. He then tested asking it to add new picks to his Google Sheets watchlist.

How It Went

Comet returned the tariff-affected list with short explanations within a few minutes. The author says the depth of results was sometimes lacking. He shows no result for the Sheets step.

Worth Knowing

Comet was available only to Perplexity Max subscribers or by invite when the post was written in August 2025.
