ChatGPT vs. Claude vs. DeepSeek: the battle to be my AI work assistant – WSJ

As I embark on my AI book adventure, I’ve hired a human research assistant. But Claude has already handled about 85% of the grunt work using its Projects feature. I uploaded all my book-related documents (the pitch, outlines, scattered notes) into a project, basically a little data container. Now Claude can work with them whenever I need something. At one point, I needed a master spreadsheet of all the companies and people mentioned across my documents, with fields to track my progress. Claude pulled the names and compiled them into a nicely formatted sheet. Now, I open the project and ask Claude what I should be working on next.
