How to choose

  1. Start with the assistant that fits the apps you already use. Built-in beats switching apps.
  2. Give each one the same real task from your week (an email, a summary, a plan) and compare the answers.
  3. If you need facts, pick one that shows sources, and click them. All assistants can be confidently wrong.
