Unfortunately, the site doesn't seem to give you any way to set a password or any form of multifactor authentication. You're sent an email with a code, and that's it. I don't mind getting an email code, but I'm really disturbed by web apps relying solely on an email code without, at least, a password. But that's what Perplexity.AI is doing.
The other interesting aspect of Perplexity Pro is its cornucopia of AI models. As you can see in the image below, you can choose between a number of different models, based on the kind of work you have. I chose Default to see what that did with the tests. After running the tests, I asked Perplexity Pro what model it used for them, and it told me ChatGPT GPT-4.
