KeyComposer — AI presentation maker for Mac. Describe the deck you want, and it generates editable slides you can actually shape — no blank-canvas dread, no wrestling with layouts. Drop in your own notes or documents to keep the content on point, then swap images, tweak text, and rearrange slides right in the app. When it’s ready, export to PDF, PPTX, Keynote, or HTML and present anywhere.

Thank you for the feedback! To dig into your case, it would really help if you could email us at [email protected] and share how you built your deck — what you were creating and which settings you used. We appreciate you taking the time to try it.

Sam problem others have mentioned. I gave it a try but it wipped out all 300 of my setapp AI credits before I could even see what it had worked on. Interesting idea but not practical for my uses.

Thank you for the honest feedback! Speed and credit usage are exactly the areas we're focused on improving right now. To dig into your case, it would really help if you could email us at [email protected] and share how you built your deck — what you were creating and which settings you used — so we can look into why it used that many credits. We're also reviewing the generation flow to make it more efficient and predictable. We appreciate you taking the time to try it.
