How to pick the right AI tool

Before paying for a subscription, ask yourself these 5 questions:

What's your weekly volume?

If you handle 1-3 files per week, the free plan covers 80% of cases. Beyond that, paid pays for itself fast.

Do you need enterprise confidentiality?

For anything client-related: Team/Enterprise tiers with zero retention required. Non-negotiable.

What's your primary working language?

If you work mostly in nuanced English, Claude beats ChatGPT. For business English, the opposite often applies.

How many tools are you ready to learn?

The 2-3-5 rule: master 2 tools deeply before adding any more. Past 5, you dilute.

What's your budget?

A $30-40/mo minimum stack covers 80% of needs. Beyond that is comfort or scale.

Frequently asked questions

Can I really start for free?

Yes. Free tiers of ChatGPT, Claude, and Perplexity cover 70-80% of beginner needs. Investing $20/mo on ChatGPT Plus pays for itself in one workday.

What's the risk if I pick the wrong tool?

Low. Most offer a free trial or refund. The real risk is NOT using AI and falling behind.

How long to master a tool?

A weekend for fundamentals, 2-3 months to really exploit its power. The learning curve is gentler than people think.

Will the tool be obsolete in 6 months?

The big ones (ChatGPT, Claude, Notion, Canva) will be here in 3 years. Smaller tools may disappear, but the skill transfers.
