What is Linearity?
Linearity bets on generation that hands back editable layers, not a flat image.
Curve ships roughly every six to eight weeks on iOS and macOS, and until now the releases were craft work: a glass effect with refraction and dispersion, corner smoothing and path bending, Super Resolution and snapping, a noise effect with SVG and performance gains. Version 6.12 changes the subject by adding Quiver AI generation, framed around keeping every layer owned and editable after the model has run. The companion app Move contributes on its own track, with Lottie export for web and mobile motion graphics.
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.
Linearity vs Spectra: editorial side-by-side
Linearity
3.8DESIGN
Linearity bets on generation that hands back editable layers, not a flat image.
◆ Current state
Curve ships roughly every six to eight weeks on iOS and macOS, and until now the releases were craft work: a glass effect with refraction and dispersion, corner smoothing and path bending, Super Resolution and snapping, a noise effect with SVG and performance gains. Version 6.12 changes the subject by adding Quiver AI generation, framed around keeping every layer owned and editable after the model has run. The companion app Move contributes on its own track, with Lottie export for web and mobile motion graphics.
◆ Where it's heading
The pitch — generation starts it, the designer owns the layers — is a deliberate contrast with image models that return a finished raster. For a vector tool on Apple platforms, that is the only version of AI that fits the product: output has to arrive as paths a designer can keep working. The release cadence and the Move track suggest the wider ambition is a design-to-motion pipeline on iPad and Mac, with Lottie as the handoff format.
◆ Prediction
Expect the next releases to extend generation deeper into the vector editing surface rather than adding separate AI panels, since editable output is the entire argument. How Quiver AI is priced or metered is not visible in these entries.
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.
