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 spends its first six weeks patching what 1.0 shipped.

Spectra Blocks and its Pro edition both launched in mid-July, and every release since has been a fix or a small addition. The window holds five patch releases across the free and Pro plugins, with automatic theme colour sync and version rollback the only additions a user would notice. The release notes carry What's Fixed headings with no fix list underneath, so the specifics are not readable from the feed.

Jitter vs Spectra: editorial side-by-side

6.3

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.

5.0

Spectra Blocks spends its first six weeks patching what 1.0 shipped.

◆ Current state

Spectra Blocks and its Pro edition both launched in mid-July, and every release since has been a fix or a small addition. The window holds five patch releases across the free and Pro plugins, with automatic theme colour sync and version rollback the only additions a user would notice. The release notes carry What's Fixed headings with no fix list underneath, so the specifics are not readable from the feed.

◆ Where it's heading

Cadence is high and substance per release is thin, which is the normal shape of a young block plugin stabilizing against the range of themes and blocks it meets in the wild. Pro is patching at the same rate as free rather than pulling ahead, so the paid tier has not yet started to differentiate on features. The fixes cluster on styling and the Button block, pointing at cross-theme rendering as the current problem area.

◆ Prediction

Expect the patch cadence to hold until a 1.1 collects new blocks. Given the free and Pro split, the next real feature work most likely lands on the Pro side first.
