What is Spectra?
Spectra Blocks is in its 1.0.x stabilization phase, shipping WordPress compatibility and early AI-adjacent editor hints.
Spectra Blocks is a WordPress block plugin in early release, still in the 1.0.x version range and working through the compatibility and bug-fix cycle typical of a product that launched recently. The most substantive recent additions are WordPress 7.1 compatibility, White Label support in the Pro tier, and an expanded icon library. The AI editor notice in 1.0.9 hints at upcoming AI writing assistance but isn't shipped yet.
What is Zeroheight?
Design system documentation making itself the constraint on AI-generated UI
Three releases in February, each recorded twice. An AI Assistant embedded in SSO-protected styleguides lets viewers chat with the guidelines to find tokens and guidance. The same Assistant became available inside Slack and Microsoft Teams via mention. And a Figma-verified connector for Figma Make brings documented design system guidance into AI-powered prototyping.

Spectra
5.0DESIGN
Spectra Blocks is in its 1.0.x stabilization phase, shipping WordPress compatibility and early AI-adjacent editor hints.
◆ Current state
Spectra Blocks is a WordPress block plugin in early release, still in the 1.0.x version range and working through the compatibility and bug-fix cycle typical of a product that launched recently. The most substantive recent additions are WordPress 7.1 compatibility, White Label support in the Pro tier, and an expanded icon library. The AI editor notice in 1.0.9 hints at upcoming AI writing assistance but isn't shipped yet.
◆ Where it's heading
The pattern here is a new block-builder plugin stabilizing its core before pushing into differentiating features. White Label support signals the product is targeting agencies and developers building client sites, not just individual site owners. The Pro tier releases tracking closely behind the free versions suggest a healthy commercial tier where upsell features (White Label, Style Guide sync) are landing on the same cadence as core fixes.
◆ Prediction
The AI editor hints will materialize as AI-assisted content generation or layout suggestions within the Gutenberg editor. The product will likely push into a more opinionated design system direction (given the Style Guide work) as it stabilizes its core block set.

Design system documentation making itself the constraint on AI-generated UI
◆ Current state
Three releases in February, each recorded twice. An AI Assistant embedded in SSO-protected styleguides lets viewers chat with the guidelines to find tokens and guidance. The same Assistant became available inside Slack and Microsoft Teams via mention. And a Figma-verified connector for Figma Make brings documented design system guidance into AI-powered prototyping.
◆ Where it's heading
zeroheight's problem has always been that documentation nobody opens does not govern anything. All three releases attack that from different sides: bring the docs to where people already are (Slack, Teams), let them be asked instead of read (Assistant), and inject them into the tool that generates UI (Figma Make). The last is the most consequential, because it changes documentation from a reference into an input.
◆ Prediction
Expect connectors for further AI generation surfaces beyond Figma Make, since the Figma Make integration establishes the pattern of design system guidance as generation context rather than as a page someone consults.
