Most AI slide tools give you a page you can't reuse. CreatePPTX starts from a topic, PDF, Word, old PPT, or a board photo. No long form. You get the story first, then real slides you can still edit.
We revise an existing PPT or PDF as that same deck: same pages, same order—not a rewrite from scratch. Formulas, graphs, and plane geometry go on the page as objects, not screenshots.
Export PPTX, open it in PowerPoint, and click a title, a table, a formula. What you see is the file you take.
