How to choose
- Choose by your main task, not by benchmark headlines
- Choose the one that connects to tools you already use
- Try free tiers on your real work for a week
- Pay for one $20-level plan before considering two
- Add a second assistant only for a clear gap

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 for accuracy, usefulness, and how much editing it needed.

Privacy settings to check
- Whether your chats are used for training
- How long chats are kept
- What connected apps can access
- Team and business data terms
Review these in each assistant’s settings before sharing work data.
The real lesson
Do not ask: “Which AI is smartest?” Ask: “Which AI makes my daily work better, in the tools I already use?”
