Choosing the best AI assistant for your work isn’t only about these ever smarter models, but also the tools and features that help you get things done. You will judge an AI not about how well it can do your job, but how many tasks you can offload to it.

“Every job is a bundle of tasks,” says Erik Brynjolfsson, a Stanford University economist and the founder of the AI-at-work consulting company Workhelix. “When you analyze jobs at that level, you can really make headway as to whether technology can help.”

What tasks you can outsource to these assistants depend on your job, your workflow and, most importantly, the AI’s capabilities. Yep, it’s a lot like hiring—you want the candidate with the right skills.
