Presentations & Slides
SaaS, open source and skills for presentations & slides work — with the limits of each written down.Before you pick
What decides it
Whether your template drives generation or is painted on afterwards. Only the first leaves real layouts in the file, so later edits stay on-brand.
What to avoid
A PowerPoint export can be one rendered picture per slide: nothing selectable, no shapes, so fixing one word means regenerating rather than editing.
What is changing
The generator is relocating into the slide editor itself — add-ins and agents that write the file format directly instead of rendering a canvas.

Skills
Skills you drop into a coding agent.Leading
- 1pptx (Anthropic official skill)Anthropic's first-party SKILL.md for building, reading and editing real .pptx/.potx files — HTML-to-PPTX generation plus raw OOXML editing. The strongest skill in the category and the one that produces genuinely editable PowerPoint; lives in the 163.9k-star anthropics/skills repo.
- 2academic-pptx-skill (Gabberflast)A community SKILL.md (~716 stars) that layers academic-deck discipline (action titles, situation-complication-resolution, citation standards) on top of Anthropic's pptx skill. Well-scoped complement rather than a standalone generator.
- 3Slidev official skillA first-party Agent Skill (SKILL.md) shipped inside the Slidev repo that teaches an agent Slidev syntax, animations, diagrams, themes and export. Official skill from a 47.8k-star project; adoption of the skill itself is still new, hence medium.
