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 Pro 1.0.6 fixes dynamic data and Loop Builder on the front end.
Spectra Blocks Pro 1.0.6 is a fix release that makes dynamic content in templates, query loops and sliders behave reliably on the live site. It follows free-plugin 1.0.12, which fixed per-card featured images in Post blocks and added shortcode Button labels in full-site editing.
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 Pro 1.0.6 fixes dynamic data and Loop Builder on the front end.
◆ Current state
Spectra Blocks Pro 1.0.6 is a fix release that makes dynamic content in templates, query loops and sliders behave reliably on the live site. It follows free-plugin 1.0.12, which fixed per-card featured images in Post blocks and added shortcode Button labels in full-site editing.
◆ Where it's heading
Spectra's last several releases have focused on matching the editor preview to the live site, first for AI-imported pages and containers, now for dynamic data and loops. The Pro add-on is filling in reliability after its style-guide and white-label features.
◆ Prediction
Expect more fidelity patches on both plugins; the entries don't point to a new feature release yet.
