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 shadcn/ui?
A component library turning into scaffolding for AI apps
shadcn/ui now spans three fronts: component bases (Base UI as the default, React Aria alongside it), a registry system others publish through, and a growing set of non-UI helpers aimed at AI SDK apps. The last two months added chat-interface components, a typography system you own outright, and now mocking utilities for paused tool calls and approvals. The component catalog keeps widening on the side with Toast and Questionnaire.

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.

A component library turning into scaffolding for AI apps
◆ Current state
shadcn/ui now spans three fronts: component bases (Base UI as the default, React Aria alongside it), a registry system others publish through, and a growing set of non-UI helpers aimed at AI SDK apps. The last two months added chat-interface components, a typography system you own outright, and now mocking utilities for paused tool calls and approvals. The component catalog keeps widening on the side with Toast and Questionnaire.
◆ Where it's heading
The center of gravity is moving from 'copy this component' to 'here is the plumbing for the app you are building', with AI applications named as the target. The registry work — GitHub registries, then server-side search — points at distributing other people's component sets, not only shadcn's own.
◆ Prediction
Expect more @shadcn/helpers surface aimed at agent workflows, and further registry features that treat third-party registries as first-class rather than an add-on.
