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 adds White Label support and ships WordPress 7.1 compatibility in its early 1.x cycle
Spectra Blocks is a WordPress block editor plugin in active early releases (1.0.x), shipping near-weekly updates. The past month pairs compatibility releases with feature additions: White Label support—letting agencies rebrand the plugin interface for client sites—landed in both free and Pro tiers simultaneously. Global Styles integration and AI Text features are under active development. The product is clearly targeting the agency market alongside individual site builders.
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 adds White Label support and ships WordPress 7.1 compatibility in its early 1.x cycle
◆ Current state
Spectra Blocks is a WordPress block editor plugin in active early releases (1.0.x), shipping near-weekly updates. The past month pairs compatibility releases with feature additions: White Label support—letting agencies rebrand the plugin interface for client sites—landed in both free and Pro tiers simultaneously. Global Styles integration and AI Text features are under active development. The product is clearly targeting the agency market alongside individual site builders.
◆ Where it's heading
Each release tracks closely behind WordPress core updates, with White Label and Style Guide integrations pointing toward a deliberate agency-market buildout. The 'AI Text' feature is being refined (1.0.8 fixes its output), suggesting it's a differentiator in active development rather than a finished surface. Expect a 1.1.x cycle focused on deeper WordPress 7.x integration and expanded AI Text capabilities.
◆ Prediction
The next meaningful release will likely be a Pro feature expansion—either more White Label controls or a broader AI content workflow—timed to the next WordPress point release.
