AI Tool Comparison
I tried replacing docs lookup with Perplexity while coding in Cursor
Perplexity answered my 'how does this library work' questions. Cursor wrote the code. Together they cut my tab-switching in half.

Perplexity
AI search and answer engine
Perplexity is an AI-powered answer engine focused on research, quick discovery, and source-backed responses.
Cursor
AI-first code editor for developers
Cursor is an AI-powered code editor designed to help developers write, refactor, and understand code faster with built-in AI assistance.
The honest comparison
While building a small feature, I stopped opening browser docs and started asking Perplexity for the API shape and the gotcha. It cited sources, which mattered when the first answer was stale.
Cursor wrote the implementation against that answer and ran it. When it broke, I pasted the error back into Perplexity rather than digging through forums.
The catch: Perplexity is occasionally confidently outdated, and Cursor will happily code to a wrong assumption. I still verify the load-bearing facts against the official docs before shipping.
Verdict: understand the library -> Perplexity. write the code -> Cursor. verify before you commit.
