Know the trade-offs

  • Claude cannot generate images or video natively
  • ChatGPT keeps its most capable agents on expensive plans
  • Grok has a record of content-safety controversies, so check its outputs closely
  • Gemini’s best features vary by country and plan
  • Every assistant can be confidently wrong
11

Choose the right one

  • Pick by your main task, not by benchmark headlines
  • Pick the one that connects to the tools you already use
  • Test the free tiers on your real work for a week
  • Pay for one $20-level plan before you consider a second
  • Add another assistant only to fill a clear gap
12

Run your own comparison

Give all four the same three tasks from your real work: one writing task, one analysis task with a file, and one research task with sources. Score each answer on accuracy, usefulness, and how much editing it took.

13

Check privacy settings

  • Whether your chats train the models
  • How long your chats are stored
  • What your connected apps can reach
  • Terms for team and business data

Review these in each assistant’s settings before you share work data.

Learn the real lesson

Do not ask: “Which AI is smartest?” Ask: “Which AI improves my daily work, inside the tools I already use?”
