Slide design requires personalizing both deck themes and page layouts. Yet, current AI agent-based methods struggle with finegrained, page-level design. Solely relying on prespecified templates or user verbose instructions, they fail to capture latent design intents, leaving Page-level Slide Personalization (PSP) unresolved. To close this gap, this work formulates PSP as an inverse planning problem. We propose to learn a design intent without assuming any knowledge of the specific executing tools (e.g., PowerPoint, Beamer) being used. However, relinquishing control over these tools makes the problem intractable to optimize end-to-end. To overcome this, we propose Spire, a principled framework to solve PSP approximately. By intentionally corrupting the visual structures of clean slides, Spire creates a verifiable task to denoise the corruption, whereby two agents learn to collaboratively refine executable designs via reinforcement learning (RL) . We present a proof that structural denoising is a consistent surrogate for PSP, and that the multi-agent formulation strictly reduces policy gradient variance in RL.  \nExtensive experiments demonstrate the superiority of Spire.  \n1 Introduction  \nSlide decks are a primary medium for communicating ideas in academia and industry [13, 34, 40] . Yet, creating a high-quality deck is a design-intensive process. Depending on the presenter and the target audience, the same content can call for different visual treatments. These treatments are often personalized toa speaker’s habitual design, a lab’s visual identity, or an organization’s brand guidelines. In short, practical slide generation is inherently a personalized task.  \n*  \nWork done during an internship at Microsoft.  \n† Corresponding author.  \n2 T.

Trained with reinforcement learning, Spire learns to infer design intents instead of using prespecified layout templates or lengthy user instructions as existing methods do [10, 53], offering both theoretical and empirical advantages.  \nRecent advances in multi-modal large language models (MLLMs) have enabled agentic pipelines that automate slide generation for practical use [9, 10, 26, 30, 38, 45, 53] . These systems typically decompose slide creation into modular stages such as outlining, asset extraction, layout arrangement, and iterative refinement, thereby improving deck-level coherence via template selection, visual feedback, and multi-agent coordination [15, 16, 30, 42, 50, 53] . However, they struggle with fine-grained page-level design, which requires deciding visual hierarchy, element alignment, spacing, and styling choices. Nonetheless, existing agentic systems handle page-level layout and styling passively: Once the content is specified, the page-level design is largely overlooked, either by following generic system-defined templates [15,24,42,53], or by requiring lengthy, explicit user instructions [10,30], instead of inferring the user’s latent intent. Consequently, they are too coarse to achieve satisfactory Page-level Slide Personalization (PSP) .  \nTo close this gap, we introduce the task of agentic PSP; the concept is depicted in Fig 1 .
