Migrating from jQuery to React

Winner: Draw

Prompt Used:

"Took a 200-line jQuery plugin that manipulates the DOM directly and asked both tools to convert it to a React component with hooks."

Result B:Semrush AI showed remarkable sensitivity to the finer details.

Analysis: For teams focused on professional users, Devin AI is the obvious starting point. Its Autonomous task execution makes it indispensable for Coding tasks. However, when the project requires Marketing output, Semrush AI becomes essential. The smart approach is to use Devin AI for conceptualization and Semrush AI for final production. Smart teams build workflows that start with Devin AI's Coding capabilities and finish with Semrush AI's Keyword data integrated.

Building a Custom Hook from Scratch

Winner: Draw

Prompt Used:
