An honest comparison, with no favourite. What each of the major AI tools is genuinely better at, what the marketing overstates, where the real differences are, and how to decide for your own business rather than copying someone else's setup. Includes the tools most course catalogues ignore.
Why most comparisons are useless, and the four things that actually decide the answer.
What each is genuinely good at and what it is not, including the ones most catalogues skip.
The commercial and confidentiality questions that should carry more weight than they usually do, and how to run a fair trial.
Running more than one tool deliberately, and how often to revisit the decision.
