How to put AI to work, and what is known about whether it works: for you, your team and your organisation.

Every page here says how sure we are. Product facts come from the companies' own pages; claims that AI saves time or money come from published studies, graded for strength. Where nobody has measured it yet, we say that too.

Evidence, gradedWhether something works comes from published studies, rated for how sure we can be. Where nobody has measured it, we say so.
No ranking for saleNo company pays to appear or to be rated, and we name no "best" tool. You choose; we show what is known.
