Does the AI generate a whole shader or edit my code?

Both. Start from a blank shader and ask for an effect, or point it at existing code and ask for changes — 'make the colors pulse with the beat', 'add bloom', 'convert this to a seamless loop'. It edits the actual GLSL in your editor, which you keep and can modify by hand.

Can it fix shader compile errors?

Yes. When a shader fails to compile, ShaderKit captures the compiler output and a Fix Errors button appears. The AI receives the exact errors and repairs the code while preserving intent.

AI shader generator that edits real GLSL

Q: Can AI really write GLSL shaders?

Yes — modern models are good at GLSL. ShaderKit's Vibe Mode sends your full shader (all buffers and shared code) plus your instruction to a Claude model, which returns a precise edit to your code. You see the diff, the shader recompiles instantly, and you can undo any change.

Q: How much does AI shader editing cost?

AI editing is part of paid plans (Creator, $7.99/month with a 7-day free trial) and uses credits per request based on actual token usage — a typical edit costs a few dozen credits out of the 50,000 included monthly. You choose between fast (Haiku), balanced (Sonnet) and strongest (Opus) Claude models per request.

Describe the effect — "add film grain", "make it loop seamlessly", "turn this into a raymarched tunnel" — and ShaderKit's Vibe Mode edits your shader code directly. Not a black-box image generator: you get working GLSL you own, see and can change.

Why editing beats generating

Image-model "shader generators" give you a picture you can't change. Vibe Mode works on the code: it reads your entire shader — every buffer pass and shared function — and applies a targeted edit. The result recompiles instantly in the live preview, and every AI change has one-click undo and redo.

Understands your whole shader

Multi-buffer aware: it sees the image pass, all four channels and the Common tab, and can coordinate edits across them — physics in one buffer, display in another.

Conversational iteration

It remembers recent edits. Say "more of that", "slower", or "undo the color change and try purple" and it knows what you mean.

Fixes compile errors

One click sends the exact compiler output to the model, which repairs the code while keeping your intent.

Choice of Claude models

Haiku for fast tweaks, Sonnet for everyday edits, Opus for the hard stuff. Cost estimate shown before every request.

Library-aware

It can pull proven noise functions, SDFs and palette tricks from the shader library as reference instead of reinventing them.

Safe by default

Performance-conscious edits with conservative iteration counts — your browser tab stays interactive.

What people ask it for

"Make the colors pulse with time" — animation and palette changes
"Add bloom and film grain" — post-processing effects
"Convert this into a seamless 5-second loop" — loop math
"Add a raymarched sphere with soft shadows" — whole techniques
"Make the particles bounce off the edges" — multi-buffer simulation logic
"Fix the compile errors" — with the real compiler output attached

Then take the result further by hand in the GLSL editor, perfect the loop, and export it as video or GIF.

How it works

Open Vibe Mode

A panel below the editor (Ctrl+Shift+V). Type what you want changed. A credit estimate appears before you submit.

The AI edits your code

Your full shader and instruction go to the Claude model you picked; it returns a minimal, targeted edit to the relevant files.

See it, keep it, or undo it

The shader recompiles instantly in the preview. Per-file change stats are shown; undo/redo history is kept separately from your manual edits.

Frequently asked questions

Does it generate whole shaders or edit mine?

Both. Start blank and ask for an effect, or point it at existing code and ask for changes. Either way it produces real GLSL in your editor that you own and can modify by hand.

Can it fix compile errors?

Yes. When compilation fails, a Fix Errors button sends the exact compiler output to the model, which repairs the code while preserving intent.
