Keynote
Keynote is Apple’s presentation app for creating, editing, and delivering slide decks on Mac and across other Apple devices.
What is Keynote?
Keynote is a presentation app for creating slide decks, visual talks, classroom materials, and business presentations on Mac. It helps users build polished presentations with themes, text, images, charts, video, and animated transitions in a streamlined editing workspace. Keynote is used by students, teachers, professionals, and teams who want to design slides, present live, and collaborate on shared work. It supports real-time collaboration, so multiple people can work on the same presentation across Mac, iPad, iPhone, and the web. Common uses include school reports, conference talks, project updates, sales presentations, and internal team briefings. As part of Apple’s iWork suite, it fits naturally into workflows that use other Apple productivity apps and iCloud for syncing and sharing.

Safety overview
Status: Safe
Keynote is a standard Apple productivity app for creating and presenting slides. Its normal behavior is consistent with that purpose, including opening documents, accessing local files you choose, and using sharing or collaboration features when you sign in to iCloud. If you use presentations with embedded media or shared links, review the source of the file before opening it and check document-sharing permissions when collaborating.
Recommendation: Keep Keynote if you create, edit, or view presentations on your Mac or other Apple devices. If you do not use presentation software, removing it is optional and mainly affects your ability to open or edit Keynote files without reinstalling the app later.
