Just started using Perplexity's new browser: Comet. Prefer it because it gives you footnotes/links to everything it says. Grok and ChatGPT can often just tell you stupid shit without citing where it got that info from. You can use most other big AI's inside Perplexity. Send agents to shop or to fact check etc. Also started using Weavy.ai - could do work there in 1 day that would otherwise take weeks.
