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?

shadcn/ui pivots from UI library to AI-native app toolkit, switching defaults and shipping agentic helpers.

shadcn/ui has completed a meaningful architectural shift. The project replaced Radix UI with Base UI as the default primitive layer, introduced the @shadcn/helpers package targeting AI SDK and TanStack AI integrations, and launched shadcn/typeset as a standalone typography system. The registry infrastructure now supports private GitHub repositories and server-side search. In less than two months it went from component library to a multi-package ecosystem.

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.

6.3

shadcn/ui pivots from UI library to AI-native app toolkit, switching defaults and shipping agentic helpers.

◆ Current state

shadcn/ui has completed a meaningful architectural shift. The project replaced Radix UI with Base UI as the default primitive layer, introduced the @shadcn/helpers package targeting AI SDK and TanStack AI integrations, and launched shadcn/typeset as a standalone typography system. The registry infrastructure now supports private GitHub repositories and server-side search. In less than two months it went from component library to a multi-package ecosystem.

◆ Where it's heading

The direction is clear: shadcn/ui is positioning itself as the default UI layer for AI-native application development. The @shadcn/helpers Human in the Loop tooling — mock paused tool calls, approvals, continuations — is a deliberate bet that agentic workflows will drive the next wave of React apps. The registry's growing infrastructure (private repos, dynamic search, the cn package consolidation) signals the project is building toward a distributable component ecosystem, not just a copy-paste library.

◆ Prediction

The next move is likely deeper @shadcn/helpers coverage of AI SDK patterns — streaming, structured output, tool result rendering — and possibly a first-party component built specifically around agent interaction UIs.
