That it knows which photograph is good. It does not, and it is not trying to. It clears what is plainly unusable and names why. Ranking your favourites is not a feature we are behind on, it is one we decided against.
That it has learned your taste. There is no profile of you, no training on your selects, no model of what you like. If that ever changes it will be something you switch on, and this page will say so before the marketing does.
That the numbers above generalise. One wedding is one wedding. We have not published a multi shoot study, and until we do, the honest claim is "this is what it did here", not "this is what it does".
That it is finished. Kepla for Mac is in private preview. Founding Access places are limited and the software is still changing under the people using it.
The bar it has to clear before any of that softens:
90% agreement with a hand cull as a floor, 95% as the target, and
zero false rejects on hero frames. A hero thrown away is the only failure that cannot be undone by a photographer who trusts the tool.
