I have tried quite a few different personal assistants over the last year, and it is evident that there is no tool that would suit everyone. Whenever I need assistance with my writing or brainstorming or general productivity, my go-to option is always ChatGPT as it performs a variety of different functions well.
While working in Gmail or Google Docs, I prefer using Google Gemini as it blends into the Google ecosystem quite seamlessly. When I have to review lengthy documents such as reports, research papers or contracts, I tend to use Claude, as it understands all of the nuances of the document.
Managing work, meetings, emails, and personal chores is more difficult to manage together. According to a Microsoft Work Trend Index report published recently, 68% of individuals do not have enough uninterrupted time to focus at work.
