Which AI should I use for work?

Asking an AI which AI to use isn't a fair test, and comparison lists go out of date fast. The answer that counts comes from your own work.

You may not need to switch

If the one you use already handles your work well, knowing it is worth a lot. You don't have to move every time someone says another one is better.

Use free plans first, carefully

Most AIs offer a free plan, so you can try before you pay. Free plans can have tighter limits or fewer features, so a poor result on one doesn't settle it. The course shows you how to run a fair test on your own work, and how to judge the results.
