The **Result Assessment Tool (RAT )** is the free open-source research software for examining and assessing search results, developed by the Search Studies research group at the Hamburg University of Applied Sciences.

Identify search queries, collect the matching search results from various search systems, such as Google and ChatGPT, analyze them, and have them evaluated by jurors. RAT can help you with all these tasks and more.
