Perplexity is a fee-for-service, at about a dollar a minute. On a weekly basis, the searches, summaries, and posts to our forum will run about $2,000 a year. I'm donating the service for an indefinite trial period while we see if it is reliable and useful to people. From the responses on the forum so far, it looks like people like it.
Unfortunately, many members do not use the website and are annoyed when a forum puts out a lot of email as this one did until I switched the default to daily summary.
