When I asit for data it's generally data that would take hours to find, ready through, accept or reject, then take notes and summarize. When I tell an AI to do it, it takes a minute or two for all the data collection and summarization. Then all I have to do is click the link provided with each piece of data and verify it, which only takes a few minutes generally.

So yes, AI saves me hours of researching and summarizing even with checking the source data.
