Is Perplexity an alternative to Google or ChatGPT?

Perplexity can complement Google for some searches: where a traditional search engine lists pages, Perplexity offers a summarized answer with its sources. Compared with ChatGPT, the use is different: Perplexity is geared toward sourced research, ChatGPT more toward writing and general-purpose tasks. The two are complementary from Ai-chatpro.

What are the limits of Perplexity?

Perplexity cites its sources, but its answer is only as reliable as the sources it consults: it still needs to be verified before any professional use. It is designed for research, less so for long-form writing, code or images. Avoid submitting confidential information. On generated content: AI and copyright.
