Figma AI Prototype converts static designs into fully interactive prototypes that simulate real app logic without writing code. Designers define conditional flows in natural language and Figma's AI wires up the interactions, state changes, and transitions automatically. The result is a shareable live demo link that stakeholders can click through like a real app.

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.
Reviewer scorecard
“This solves the single most painful gap in the Figma workflow — the moment where a beautifully composed static design has to be manually rewired into a clickable prototype with 47 connector arrows. The natural language conditional logic ('if user taps this button and the cart is empty, show this state') maps directly to how designers already think about flows, which means the AI is filling in grunt work rather than making design decisions. The one design concern: the generated prototype interactions need to be inspectable and editable after generation, not a black box — if Figma nailed that editing surface, this earns a 90.”
“The output here is a clickable prototype that actually behaves like the real app — conditional states, error flows, loading states — rather than the usual linear click-through that fakes interactivity. That's a meaningful leap because it lets you test the actual design logic, not just the happy path. The fingerprint risk is real though: if the AI is making micro-decisions about transition timing and easing, those defaults better be tasteful, because a thousand designers shipping the same 300ms ease-in-out is how every prototype starts feeling like the same app.”
“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.”
“The job-to-be-done is razor sharp: designers need to communicate real app behavior to stakeholders and developers without waiting for an engineer to build a prototype. Figma already owns the canvas where that design lives, so the zero-export, zero-handoff shareable link is exactly the right product decision — it keeps the loop inside Figma rather than pushing users to ProtoPie or Framer for logic. The completeness question is whether complex data-dependent flows (authenticated states, API-driven content) can be simulated convincingly, because that's where current prototyping tools force you to context-switch and where this tool lives or dies.”
“Figma is doing to prototyping what it did to handoff — absorbing an adjacent tool category by making 'good enough' free inside the existing subscription. ProtoPie, Framer, and Axure are directly in the blast radius, and for 80% of use cases this will be sufficient, which is exactly the problem: the remaining 20% of complex conditional logic, multi-user flows, and data simulation is where real product design happens, and 'natural language conditionals' is an untested claim for anything beyond toy examples. What kills this in 12 months isn't a competitor — it's Figma's own track record of shipping features that demo well at Config and then sit half-finished for two years. The AI make-grid and content generation features from 2024 are still unreliable for production use.”
“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.”
“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.”
“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.”
