I needed a fitness tracker and smartwatch under $200. I did what I have always done. A dozen browser tabs, a few prompts in AI chatbots, and some YouTube review videos thrown in for good measure. Review sites disagreed on the brands. YouTube reviewers hyped watches, while Reddit threads became too confusing. Overwhelmed with research, I reached the point we call browser fatigue. So I tried something different. I dumped every source into Gemini Notebook and asked it to make sense of the mess. It became my filter and helped me make an informed decision.
