Gamma alternatives for editable AI presentations

Presenton is the closest dedicated presentation app here: generate decks from prompts or source documents, reuse PowerPoint designs, edit slides in a canvas or chat and export editable PPTX files. Local model connections and a generation API support desktop or team workflows.

SurfSense creates editable PowerPoint presentations from selected documents, alongside Word reports, spreadsheets and PDF briefs. It suits research-based decks where cited answers and source organization matter as much as visual drafting.

OpenMAIC creates educational presentations with quizzes, spoken explanations and interactive activities. Import an existing PowerPoint deck, revise the lesson through conversation, and export editable PPTX slides or interactive HTML pages.

PPT Master produces editable PowerPoint shapes, text, charts and tables using your own templates. It suits people comfortable with an AI agent and Python workflow; it is a presentation-generation project rather than a standalone slide editor.

LobsterAI covers PowerPoint creation as part of an office-task agent. It can analyze spreadsheets and produce charts or reports alongside a deck, with previews of generated files. This is a presentation-file workflow rather than Gamma-style web publishing.

AFFiNE turns outlines into slides and uses frames on its document-and-whiteboard canvas as presentations. It suits teams presenting material already collected in a visual workspace, rather than replacing Gamma with a dedicated deck generator.
