Chrome's Prompt API lets web developers call Gemini Nano — Google's compact, locally-running language model — directly from JavaScript, without any server requests after the initial model download. The API accepts text, audio (AudioBuffer or Blob), and visual inputs (images, canvas elements, video frames), returns streaming text responses, and supports JSON Schema-constrained structured output for reliable data extraction. Sessions are created via LanguageModel.create(), with each session maintaining a token-aware context window that prunes older messages automatically while preserving system prompts. The Prompt API complements other Chrome AI primitives including the Summarizer, Writer, Rewriter, Translator, and Language Detector APIs — all running fully on-device. Model requires 22GB+ free disk space for the initial download; subsequent use works offline. This is a meaningful shift for web AI. Developers can now build privacy-preserving AI features — local transcription, smart autocomplete, content classification, on-page summarization — without touching a cloud API or paying per-token costs. Currently supports English, Japanese, and Spanish. Available via Chrome's Origin Trial program with broader rollout expected through 2026.

Figma's Design-to-Code Agent converts any Figma frame into production-ready React components styled with Tailwind CSS, including responsive breakpoints and accessibility attributes. It's rolling out to all Professional and Organization plan users as an integrated feature inside the existing Figma product. The agent targets the historically painful handoff gap between design and engineering teams.
Reviewer scorecard
“The JSON Schema structured output is the feature I've been waiting for — finally you can extract clean data from user-typed text without a backend. The 22GB download is a real onboarding hurdle, but once the model is cached, the latency is basically zero compared to cloud APIs. This changes the math for privacy-sensitive consumer apps.”
“The primitive here is a context-aware AST-to-JSX compiler that reads Figma's internal node tree instead of a screenshot — which is meaningfully different from every Anima and Locofy attempt that came before it. The DX bet is that developers want to paste generated components directly into their codebase rather than scaffold from scratch, which is the right call as long as the Tailwind class output doesn't look like it was generated by someone who learned CSS from a YouTube thumbnail. The moment of truth is whether the responsive breakpoint logic holds up on a real design system with nested auto-layout frames, not a three-card landing page demo — I'd want to see that before calling this production-ready. Not a weekend Lambda replacement; the Figma internal graph access is the actual moat here, and no prompt wrapper touches it.”
“A 22GB model download as a prerequisite for a web feature is going to have terrible adoption outside of developer demos. Most users won't have that space or patience, and the English/Japanese/Spanish-only limitation rules it out for global products. Wait for the model to shrink before betting your product on this.”
“Category is design-to-code, direct competitors are Locofy, Anima, Builder.io Visual Copilot, and honestly GitHub Copilot with a Figma screenshot pasted in — and Figma wins purely on distribution, not on output quality claims I can verify. The scenario where this breaks is a complex design system with custom tokens, multi-level component inheritance, and a Storybook integration expectation: the agent will output flat Tailwind soup instead of respecting the token layer, and a senior frontend dev will spend more time cleaning up than building from scratch. What kills this in 12 months isn't a competitor — it's Figma's own historical pattern of shipping half-features that stall in beta; if the React output doesn't handle state and doesn't wire to a real component library, developers will route around it. Still shipping because it's in the product you already pay for, and 'good enough for a first pass' has real value at scale.”
“On-device inference in the browser is the endgame for consumer AI. No API keys, no latency, no data leaving the device — this is what private-by-default AI looks like. The browser becomes the AI runtime, and Google just got there first. The model size issue is a 2026 problem; by 2027 it'll be 2GB.”
“Real-time image and canvas analysis directly in the browser opens up creative tooling that wasn't possible without a backend. Think live design feedback, style detection from reference images, or on-the-fly alt-text generation — all without a cloud API call. The streaming responses make it feel snappy enough for interactive UX.”
“The irony of a design tool shipping a feature that converts design decisions into utility-class soup is not lost on me — the output is Tailwind, which means every spacing decision, typographic choice, and color system the designer built in variables gets flattened into hardcoded hex values and arbitrary bracket classes the moment it crosses the bridge. The feature lives inside Figma's existing right-panel interaction model, which is the right place for it, but there's no signal that the agent respects design tokens as a first-class output target rather than resolving them to raw values. Until the generated code honors the variable layer as CSS custom properties or a token config, this is a tool that takes considered design decisions and turns them into technical debt — which is the opposite of what the handoff problem actually needs solved.”
“The buyer is already in the building — this is a retention and upsell feature for Professional and Org plan users, not a new acquisition channel, and Figma knows exactly what they're doing: making downgrade decisions more painful by embedding workflow value that has no clean export. The moat is distribution and data: Figma owns the design graph, the comment threads, the component library, and the version history, and any standalone design-to-code tool is working from a JPEG of that context while Figma works from the source. The stress test is what happens when VS Code Copilot ships a Figma plugin that does 80% of this for free inside the developer's existing environment — Figma's answer has to be that the designer-side workflow integration justifies the price, and right now that answer is credible. Shipping because this is a feature that strengthens a moat that already exists, not a startup trying to build a new one.”
