SlideViber

SlideViber is an open-source AI presentation tool that lets AI agents design 1920x1080 SVG slides, preview them in the browser, and export them to native, fully editable PowerPoint (.pptx) files. It targets developers and teams who want their coding or chat agents to build presentation decks without vendor lock-in. Instead of having the agent write OOXML directly, SlideViber has it draw slides as SVG, then a built-in converter deterministically produces the PPTX. The team chose SVG because it is roughly an order of magnitude more token-efficient than raw OOXML, it is the vector format LLMs know best from web training data, and it lets the agent draw arbitrary vector graphics rather than being limited to preset shapes. The typical workflow is iterative: you prompt the agent, preview the rendered SVG slide in the browser, refine until you are satisfied, then export to a real .pptx you can keep editing in PowerPoint, Keynote, or Google Slides. SlideViber is distributed under the MIT license and installs from GitHub via a short paste command, so it plugs into an existing agent setup as a skill rather than running as a hosted SaaS product. It is best suited to people comfortable wiring a tool into their own AI agent workflow.

Developers and teams use SlideViber to let their AI agents generate editable PowerPoint decks from SVG slides.
