Perplexity: AI answer engine that searches the web and cites its sources.
ChatPDF: Upload a PDF and chat with it to find answers fast.
The best way to decide is to run the same week of real work through both — most offer a free plan or trial — and compare how long tasks take, what your team prefers, and the total cost for your number of users including renewal pricing.
