Many comparisons of AI PPT makers collapse the whole process into generation speed. That misses the operational question: what must happen to the deck after it is made? A deck for a public product launch may need a stable URL and motion in the browser. A quarterly report may need colleagues to edit charts inside Microsoft Office. These are different delivery contracts, even when both searches begin with the word PPT.
In the htmlslides workflow, a coding agent receives the htmlslides skill, a topic, evidence, and an optional template direction. It writes the source as HTML rather than exporting a PowerPoint file. The finished deck can then be imported for playback and distribution. This makes the document inspectable and web-native, but it also means the user should not expect pixel-perfect round trips through PowerPoint.
The honest description is therefore narrower than a one-click promise and more useful in practice. htmlslides is not a one-click Gamma clone, nor is it a hidden PowerPoint editor. It is a presentation environment for people who are comfortable producing the artifact with an AI agent and want the final result to behave like a web page with slides.
