Marble 1.1 and 1.1 Plus are the latest updates to World Labs' generative 3D world model, the flagship product from the spatial AI startup co-founded by Fei-Fei Li. The 1.1 release focuses on visual quality improvements: better lighting and contrast handling, reduction in common visual artifacts (flickering, geometry drift at scene edges), and more consistent object coherence across viewing angles. Marble 1.1 Plus introduces dynamic scale — the model's most significant capability expansion since launch. Previous generations produced worlds of fixed spatial extent; 1.1 Plus automatically analyzes scene complexity and expands world coverage by deploying up to five "dynamic cubes" in a single generation pass. The result is environments that fill out naturally across a larger footprint without requiring multiple generation runs or manual stitching. Target use cases include game environment prototyping, architectural visualization, and training data generation for robotics simulators. World Labs has positioned Marble as the world's first commercially available spatial intelligence product, and the 1.1 updates shipped April 7-8, 2026 via the marble.worldlabs.ai web app. The dynamic scale feature in 1.1 Plus is available on paid plans, while quality improvements in 1.1 apply across all tiers. The updates arrive as competition in AI 3D generation heats up from tools like Luma AI and TripoSG.

PageOn.AI 3.0
Multi-format visual agent: slides, posters, 3D, and live-data infographics from one prompt

PageOn.AI 3.0 repositions itself from a "slide maker" to a full multi-format visual agent. A single prompt can produce slides, marketing posters, social graphics, infographics, and now — uniquely — interactive content with 3D models, animated diagrams, and live data feeds embedded directly in the output. Version 3 introduces three major architectural changes: cross-canvas coherence (so a brand's visual identity stays consistent across 20 different output formats generated in one session), point-and-chat editing (click anywhere on the canvas and describe the change you want in natural language), and intent-driven layout (the agent detects whether your content is a board pitch, a social post, or a technical explainer and adapts structure and tone accordingly). The interactive output category is the genuine differentiator. Competitors in the AI slide space (Gamma, Beautiful.ai, Tome) produce static or mildly animated content. PageOn claims to be the only tool at consumer pricing that outputs live-data-connected, 3D-capable visual documents. Built by a team of five, now with 2,224 Product Hunt followers and a 4.0-star rating across 400+ reviews. If the interactive output holds up in real-world testing, this is a meaningful jump from the crowded "AI slide tool" category.
Reviewer scorecard
“Dynamic scale in a single generation pass is the feature I've been waiting for. Having to stitch multiple fixed-extent generations together was the main workflow pain in Marble 1.0 for game environment prototyping. If 1.1 Plus delivers on the demo quality, it cuts 3D world prototyping time by an order of magnitude.”
“Live-data-connected presentation outputs mean I can build a quarterly metrics deck once and have it auto-update — that's a legitimate workflow unlock. The point-and-chat editing model is also how AI design tools should work: direct manipulation with natural language, not prompt-then-regenerate-everything.”
“The demos are impressive but the generation-to-game-engine pipeline is still manual and lossy. You can't export clean meshes with proper LODs or collision geometry — it's a concept tool, not a production asset pipeline. Until you can import Marble output directly into Unity or Unreal with proper metadata, this stays in the 'cool demo' category for most game devs.”
“'3D models and live data in one prompt' claims have appeared in every AI design tool launch since 2024 and almost none have delivered at the fidelity shown in demos. The 4.0-star rating with 400+ reviews suggests real usage but also real frustration — I'd want to see the 2-star reviews before committing to this for client work.”
“Fei-Fei Li's bet that 3D spatial intelligence is the next fundamental modality is looking more plausible with each Marble update. Dynamic world generation at scale is a prerequisite for training embodied AI agents — Marble's real customer may be the robotics and simulation market, not game studios.”
“The multi-format visual agent category will eat traditional design tool subscriptions within 18 months. PageOn's bet on interactive-first output — not just prettier static slides — positions it ahead of incumbents who are still optimizing for PDF export.”
“For concept artists and production designers, Marble 1.1 is a rapid ideation tool that works. Generating a believable environment in 60 seconds to show a client a mood and spatial feel — even as a rough 3D sketch — beats days of modeling. The dynamic scale expansion is exactly what cinematic environment work needs.”
“Cross-canvas coherence is the feature I've been waiting for from any AI design tool. The nightmare of maintaining brand consistency across 12 different slide decks and 8 social formats is real — if PageOn 3.0 actually solves that, it earns a permanent spot in my toolkit.”
