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.

Suno v5.5, released March 26, 2026, is the biggest quality jump in the AI music generator's history. Three headline features: Voices (generate in the style of your own uploaded voice samples), Custom Models (fine-tune the base model on your music library to create a personalized generation engine), and My Taste (a preference learning system that adapts to your ratings over time). The technical foundation under v5.5 has been substantially upgraded — the model produces noticeably better vocal clarity, more coherent song structure across full 4-minute tracks, and dramatically improved instrumental separation. Genre blending that used to produce muddy outputs now sounds intentional. The platform has also improved its handling of unusual prompts, languages, and non-Western musical traditions. Suno now serves tens of millions of creators globally and has produced over a billion songs total. The Voices feature in particular marks a shift from "generate music" to "generate my music" — a personalization layer that could finally make AI music feel less generic. With a Warner Music Group partnership confirmed, the question isn't whether Suno is the leading AI music platform — it's whether the industry can adapt before Suno becomes the industry.
Reviewer scorecard
“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.”
“Custom Models via fine-tuning on your own library is the killer feature for developers building music products on top of Suno's API. The personalization stack (Voices + My Taste + Custom Models) finally makes programmatic music generation feel like a platform rather than a toy.”
“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.”
“The Voices feature raises immediate copyright and consent questions — whose voice, with what training data? The WMG partnership suggests commercial pressure is shaping features. Real musicians are still getting squeezed out, not empowered, by these tools.”
“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.”
“Music is about to bifurcate: AI-generated ambient/functional music (playlists, game scores, ads) will be dominated by tools like Suno v5.5, while human artists find new premium niches. This is the iPod moment for music production.”
“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.”
“My Taste's preference learning finally solves the 'prompt fatigue' problem — I can stop trying to describe what I want and just rate tracks until the model learns my aesthetic. This is how creative AI tools should work.”
