AI vector generators create a specific type of mess. You get beautiful shapes wrapped in hundreds of unnecessary anchor points, stray points floating in empty space, and hidden objects that add file weight without contributing to the design. Cleaning this up manually takes longer than generating the art in the first place.
Scripts solve this. They automate the repetitive cleanup tasks that AI art requires, letting you focus on refinement instead of repair. Here are five scripts that turn post-AI cleanup from a chore into a one-click operation.
1. Simplify Path: The Anchor Point Reducer
AI vector generators love anchor points. They scatter them like confetti, creating smooth curves out of hundreds of tiny segments. This makes files bloated, slows down editing, and can cause issues with cutting machines or RIP software . The Simplify command is the fix.
What it does: Object > Path > Simplify analyzes your selected paths and removes redundant anchor points while preserving the original shape. With the “More Options” toggle open, you can preview the original path against the simplified version and adjust a slider to control how aggressively points are removed .
Why it matters for AI art: AI often traces raster outputs with precision far beyond what any human needs. Simplify reduces a 1,226-point path to 400 points with no visible change . That smaller file size means faster rendering, easier editing, and happier collaborators.
How to use it: Select your AI-generated vector, go to Object > Path > Simplify, click the three dots to expand options, check “Preview,” and drag the Curve Precision slider until the shape just starts to change—then back off slightly.
2. Clean Up: The Stray Point Eliminator
When AI generates vectors, it sometimes leaves orphaned points floating in space. These stray points come from incomplete paths, errant pen clicks during tracing, or bugs in the generation process. They add file complexity without contributing to the visible artwork, and they can change the bounding box of your illustration .
What it does: Object > Path > Clean Up scans your document for three types of debris: Stray Points (isolated anchor points with no connecting paths), Unpainted Objects (shapes with no fill and no stroke that are not being used as masks), and Empty Text Paths (text objects with no characters) .
Why it matters for AI art: AI-generated vectors often contain invisible artifacts—paths that were created during the trace but never finalized. These artifacts are not visible, but they still process during PDF generation and can cause issues with production workflows .
How to use it: Run Clean Up as the first step after importing any AI-generated vector. Check all three boxes. Let Illustrator delete what is unnecessary while preserving what is visible.
3. smoothing.jsx: Curve Optimization
Standard Simplify works well on geometric shapes. But AI-generated organic forms—illustrations, characters, abstract swirls—benefit from a different approach. The smoothing.jsx script from the illustrator-scripts collection applies Catmull-Rom spline algorithms to rough paths, creating smoother, more natural curves .
What it does: Unlike Simplify, which reduces point count, smoothing.jsx recalculates the curve geometry itself. The result is often a more elegant, more finished-looking shape with fewer abrupt direction changes.
Why it matters for AI art: AI vector generation often produces “noisy” curves—paths that technically follow the right shape but do so with unnecessary micro-fluctuations. Smoothing removes that noise, giving the artwork a professional polish.
How to use it: Available as part of the open-source illustrator-scripts collection. Download, place in your Illustrator Scripts folder, and run on selected paths. Preview the result and adjust the smoothing intensity based on the organic complexity of your artwork .
4. flatten.jsx: Straight-Line Optimization
AI vector generation handles straight lines poorly. What should be a clean horizontal edge often becomes a series of tiny angled segments—subtle, but detectable in production. The flatten.jsx script converts these segmented approximations into true straight paths .
What it does: flatten.jsx analyzes selected paths and identifies segments that are mathematically straight but represented as multiple anchor points. It replaces these with single straight line segments, dramatically simplifying the path structure for geometric elements.
Why it matters for AI art: This script is essential for AI-generated illustrations with architectural elements, product packaging mockups, or any design containing intentional straight edges. A path that looks straight but contains 20 anchor points will cause issues in cutting, printing, or further editing.
How to use it: Select geometric elements of your AI artwork and run flatten.jsx. The script preserves the visual appearance while cleaning the underlying vector math.
5. handleGlue.jsx: Anchor Point Alignment
AI vector generation often creates paths with misaligned anchor handles. This leads to small bumps, unexpected curves, and inconsistent stroke behavior that becomes visible only when you scale the artwork or apply effects.
What it does: handleGlue.jsx “snaps” anchor handles to logical alignments, cleaning up the microscopic misalignments that AI introduces .
Why it matters for AI art: This is subtle work, but it matters for professional output. A path with slightly misaligned handles may look fine at 100% zoom but behave unpredictably when scaled, skewed, or used as a mask. handleGlue.jsx prevents those surprises.
How to use it: After simplifying and cleaning your AI artwork, run handleGlue.jsx on complex curved paths. The script will not alter the visible appearance but will ensure the vector math is stable.
The Workflow
The most efficient post-AI cleanup follows this sequence:
- Clean Up to remove invisible debris.
- flatten.jsx to optimize straight edges.
- Simplify manually on geometric shapes.
- smoothing.jsx on organic, curved elements.
- handleGlue.jsx as a final pass on complex paths.
Each script solves a specific problem. Together, they transform an unworkable AI mess into production-ready vector art in seconds, not hours. The AI gets you started. These scripts get you finished.
