Claude Design is Anthropic's first direct entry into visual tooling — an experimental product from Anthropic Labs that converts conversational prompts into interactive prototypes, pitch decks, mockups, and marketing assets. It ships as part of Claude subscriptions (Pro, Max, Team, Enterprise) with no additional cost. The tool is powered by Claude Opus 4.7 and supports iterative refinement through natural language — you describe a change and the prototype updates in real time. Users can also use inline editing, parameter sliders for style adjustments, and group collaboration for shared review. When satisfied, assets export directly to Figma, Canva, PowerPoint, or raw HTML/CSS. This positions Claude as a competitor to Figma's AI features, Framer AI, and v0.dev — but with a conversation-first interaction model rather than a canvas. The inclusion in existing subscriptions means Anthropic is using Claude Design to add stickiness to its paid plans rather than launching a standalone design product. For founders, PMs, and non-designers who need to move from idea to prototype quickly, it removes the "I need a designer for this" bottleneck entirely.

FluidCAD is a web-based parametric CAD application that models geometry through JavaScript code instead of mouse-driven GUI operations. Users write code to define extrusions, fillets, boolean operations, and patterns; dragging in the live viewport generates code values that get locked into the script. It supports STEP file import/export with color, a feature history that can be stepped through and rolled back, and VS Code extension support. Gained 149 upvotes on Show HN today, targeting engineers who want code-first CAD with a traditional feature tree.
Reviewer scorecard
“The Figma export is what makes this actually useful rather than just a toy — I can generate a first-pass mockup, hand it off, and not block design on my backlog. Included in the subscription I'm already paying is a no-brainer.”
“FluidCAD solves the thing OpenSCAD got wrong: the 'drag to prototype, lock to code' loop makes it accessible without sacrificing programmability. STEP export means it fits into actual hardware workflows, not just rendering. For software engineers doing mechanical work, this is the missing middle ground between Fusion 360's complexity and OpenSCAD's austerity.”
“Every AI design tool promises real prototypes but delivers web screenshots that need to be rebuilt from scratch. The Figma export quality will make or break this — if it produces layered, editable files, it's a ship. If it's flat images, it's a gimmick. Reserve judgment until reviews of actual exports are in.”
“Code-first CAD has a 30-year history of failing to reach mainstream adoption because engineers and designers don't want to write JavaScript. FluidCAD will appeal to a very narrow slice of software developers who also do mechanical work. The STEP import/export is table stakes, not a differentiator, and Onshape's API does everything this does for teams who need collaboration.”
“Anthropic entering design tooling signals that AI labs are expanding from model APIs into workflow products. This is the beginning of a vertically integrated AI suite — Claude handles your code, design, analysis, and documentation in one conversation. Figma's moat just got meaningfully challenged.”
“When AI can generate CAD from natural language, the tools that survive will be the ones with programmatic, diffable representations — not binary blob formats. FluidCAD's JavaScript-first approach puts it in exactly the right position for the AI-assisted hardware design wave that's coming. This is the OpenSCAD for the LLM era.”
“This is what I've been waiting for — a design tool that reasons about layout, hierarchy, and brand rather than just rearranging templates. The conversational refinement loop feels more natural than sliders and panels. I'll be using this for every client pitch deck from now on.”
“I appreciate the concept but the UI is clearly built by engineers for engineers. There's no real onboarding, the documentation assumes CAD literacy, and the JavaScript API surface is intimidating for anyone coming from traditional design tools. Until there's a visual-first entry point, this stays a curiosity for most designers.”
