Abstract
Current AI agents compellingly describe slides. However, AI-assisted slide editing requires more than understanding: the output must retain layout, style, component structure, and native editability. Towards, AI-assisted slide editing, existing agents operate on screenshots or weak document representations and often fragment coherent visual units, rasterize editable content, or break layout. In contrast, for controllable slide editing we introduce an agentic framework, SlideForge, which builds a Deck State Graph, an executable slide state that links visual decomposition, native PPTX object structure, and perceptual organization. By recovering human-referable components while retaining fine-grained editable structure, SlideForge supports theme-preserving reconstruction through slide-native operations and rendered-state verification. We further introduce an evaluation paradigm for controllable slide transformation that jointly measures component recovery, preservation, restyling consistency, visual quality, and native editability. Experiments show that SlideForge outperforms direct prompting, screenshot-based agents, and generic code-agent baselines across these dimensions.
