What is Jitter?
Jitter turns its AI effects engine into a packaged panel — and a pricing tier to match.
Jitter is a browser-based motion design tool shipping weekly, and its center of gravity has moved to AI-generated effects. After launching Jitter AI (build custom effects from a prompt) in May, it has consolidated shaders and effects into a dedicated Effects panel and introduced an AI-heavy Ultra pricing tier. Alongside, it keeps expanding the core editor: components, counters, background blur, glass, and displacement shaders.
What is Spectra?
Spectra Blocks Pro 1.0.7 fixes headers on block themes as the fidelity work continues.
Spectra Blocks spent the autumn on fidelity: matching editor previews to live sites, fixing classic-theme spacing and Site Editor alignment, and letting its content count toward Yoast and Rank Math. 1.0.14 improved front-end loading and Slider accessibility, 1.0.15 added custom HTML attributes, and Pro 1.0.7 fixes per-page headers on Full Site Editor themes along with Loop Builder, Countdown and Modal rendering.

Jitter
6.3DESIGN
Jitter turns its AI effects engine into a packaged panel — and a pricing tier to match.
◆ Current state
Jitter is a browser-based motion design tool shipping weekly, and its center of gravity has moved to AI-generated effects. After launching Jitter AI (build custom effects from a prompt) in May, it has consolidated shaders and effects into a dedicated Effects panel and introduced an AI-heavy Ultra pricing tier. Alongside, it keeps expanding the core editor: components, counters, background blur, glass, and displacement shaders.
◆ Where it's heading
The direction is clear — grow the effects and shaders library, let AI generate whatever isn't pre-built, and monetize the resulting AI usage through tiered credits. Editor fundamentals such as reusable components, batch export, and timeline UX are maturing in parallel to keep it viable for team workflows. Jitter is positioning as the place where designers both use and generate motion effects without leaving the canvas.
◆ Prediction
Expect workspace-level components (already flagged as next), a deeper AI effects library, and more usage-based gating as the Ultra tier establishes AI credits as the pricing lever.
Spectra
5.0DESIGN
Spectra Blocks Pro 1.0.7 fixes headers on block themes as the fidelity work continues.
◆ Current state
Spectra Blocks spent the autumn on fidelity: matching editor previews to live sites, fixing classic-theme spacing and Site Editor alignment, and letting its content count toward Yoast and Rank Math. 1.0.14 improved front-end loading and Slider accessibility, 1.0.15 added custom HTML attributes, and Pro 1.0.7 fixes per-page headers on Full Site Editor themes along with Loop Builder, Countdown and Modal rendering.
◆ Where it's heading
After the AI page import push in September, releases have been about trust in the output: render it correctly, make it count for SEO, now make it fast and accessible. The Pro add-on follows the same cadence with design-token and dynamic-data fixes.
◆ Prediction
Expect accessibility passes on other interactive blocks such as tabs or accordions, following the Slider, alongside further Pro fix rounds.
