AI shopping tools can reduce both money and time spent online, according to a PCMag article. Deep research via chatbots like ChatGPT or Gemini simplifies deciding what to buy; the author used a prompt with personal details to find a chair, and the resulting report made the process "much easier and significantly shorter."

The author asked Alexa about a kettle's heating speed and was told that "customers consistently praised its heating speed." Gemini’s virtual try-on feature on Google Shopping lets users upload a selfie to try on clothes, though not every item is available.
