while i appreciate that you are working on something to give away for free, providing your own little world of value... your comment makes it sound like you've never made powerpoints before. of course, there are a bajillion powerpoints out there in the wild that layer white rectangles to erase stuff from screenshots of charts, among numerous other atrocities
And if you task Claude with making a moderately sized powerpoint matching existing style guides, it will spend at most 30% of the time on the initial version. The remaining time is spent rendering out slides, looking at them and adjusting them
Of course AI can one-shot slides, but if you want good results where everything is aligned and has proper contrast you need a visual feedback loop
