How to choose an AI tool

Start with the task, not the trend

AI tools can help with writing, research, coding, meeting notes, image creation and repetitive work. The best choice is not necessarily the most popular one. Start by describing one task you want to improve and how often you do it.

1. Define a useful test

Choose a real task you already understand. For example: turn rough notes into a clear email, summarise a public report, draft a study plan or generate ideas for a presentation. Prepare a small set of representative examples so you can compare tools fairly.

2. Compare the things that matter

Output quality: Is the result accurate, relevant and easy to edit?
Ease of use: Can you get a good result without repeatedly rewriting prompts?
Limits: Check message, file, image or usage limits on the plan you would actually use.
Privacy: Read how the provider handles prompts, uploaded files, retention and model training. Do not upload confidential work or personal data unless you are authorised and understand the terms.
Integrations: Does it work with the documents, browser or software you already use?
Total cost: Include taxes, billing frequency, seat limits and the cost of add-ons.

3. Test free access before subscribing

Use the free tier, trial or demo where available. Test the same task in two or three products, then score each on quality, time saved and friction. A tool that saves ten minutes every day may be worth paying for; a tool used once a month may not be.

4. Verify important answers

AI output can sound confident and still be wrong. Check facts, calculations, citations, legal or financial claims, and technical recommendations against reliable primary sources. Treat generated text as a draft, not proof.

Simple decision rule: Pay only when a tool repeatedly solves a real problem, its paid features are genuinely needed, and the price is reasonable for the time or quality it gives you.

I know which paid feature I need and why.

Keep your shortlist small

For many people, one general assistant plus one specialist tool is enough to begin. Avoid paying for several products that perform nearly identical jobs. Revisit your choice when your needs change, and check provider websites for current features and prices.
