Is ChatGPT or Perplexity better for developers?

ChatGPT is better for code generation and creative problem-solving. Perplexity is better for researching documentation, finding solutions, and getting sourced answers.

Which has more accurate information?

Perplexity typically provides more accurate factual information because it searches the web and cites sources. ChatGPT can hallucinate facts but excels at reasoning.

Can I use both ChatGPT and Perplexity?

Absolutely! Many developers use ChatGPT for coding and Perplexity for research. With Idlen, you can earn money while using both.

Which is better for learning new technologies?

Perplexity is better for researching new technologies due to its real-time web access and citations. ChatGPT is better for hands-on learning through code examples.

What about coding capabilities?

ChatGPT (especially GPT-4) is significantly better at code generation. Perplexity can help with coding questions but isn't optimized for code creation.
