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 is turning a component registry into infrastructure for AI app UIs.
shadcn/ui has stopped being just a Radix-based component registry. It now supports three primitive bases - Radix, Base UI (the default since July) and React Aria - and has been shipping registry infrastructure of its own: GitHub-repo registries in June, server-side search in July. The newest work sits outside components entirely, in @shadcn/helpers, a utility package aimed at AI SDK and TanStack AI.

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.
shadcn/ui
6.3DESIGN
shadcn/ui is turning a component registry into infrastructure for AI app UIs.
◆ Current state
shadcn/ui has stopped being just a Radix-based component registry. It now supports three primitive bases - Radix, Base UI (the default since July) and React Aria - and has been shipping registry infrastructure of its own: GitHub-repo registries in June, server-side search in July. The newest work sits outside components entirely, in @shadcn/helpers, a utility package aimed at AI SDK and TanStack AI.
◆ Where it's heading
Two arcs run in parallel. One is decoupling from any single primitive vendor, which turns the registry into a distribution layer rather than a wrapper around Radix. The other is a push up the stack into AI application code - chat interface components in June, typeset for streaming text in July, and now mocks for paused tool calls and approvals. The components are becoming a means to a larger surface.
◆ Prediction
Expect the helpers line to keep extending along agent-workflow states - the entries so far move from introduction, to chat surfaces, to human-in-the-loop - and more composite patterns like Questionnaire rather than new primitives.
