I tried it myself because I needed reliable info for my research - and the source citations in Perplexity are really a huge advantage 🔗 You can see directly where the answer comes from and verify it yourself, instead of constantly asking ChatGPT "but where does that come from?" You notice the difference too with current topics, Perplexity is just quicker on the draw there.
That said: it doesn't automatically mean Perplexity is always better. For exploratory research, where you're more in brainstorming mode, ChatGPT can sometimes be more comfortable. I'd say just try both in parallel for two weeks and see which workflow feels better for you - it doesn't have to be either/or 😊
