Our take, from the rated issues
Gamma is the second Issue 001 tool in the top ten and the one that surprised us most in testing. It generates polished decks, docs, and one-pagers from a prompt or a rough outline, which sounds like a convenience until you tally how much of a PM's week goes into formatting decisions nobody should be paid to make.
The roadmap review is the clearest case. The thinking in a strategy memo is the PM's job; turning it into twelve presentable slides is not, and Gamma collapses that second half into minutes. We found the same leverage in launch recaps and quarterly readouts — artifacts that need to look considered because their audience is. The output reads as competent-agency generic out of the box, and it improves sharply once you feed it your own template and a couple of past decks.
It holds rank seven rather than higher because a deck is a container: the tool speeds the packaging, not the judgment inside it, and a weak strategy becomes a beautiful weak strategy. The caveat we logged in Issue 001 stands — do not let the polish outrun the thinking. For PMs whose influence runs through review meetings, though, reclaiming the design-polish hours every week is real, compounding leverage.
