NKD Klein Tools
ComfyUI nodes that turn a Flux Klein workflow into something simple. Plug in your model, drop an image, write a prompt, and go — no manual wiring of internal pieces. Whether you want to generate from scratch, transform an existing photo, paint over a specific area, or zoom in for a high-detail touch-up, a couple of nodes handle it all. Optional extras let you build the prompt from curated presets, and control how much each reference image shows up — or which part of the canvas it lands on.

What you can do with it
- Generate images from a prompt — just connect the model and write what you want.
- Transform an existing image — drop your image into the reference slot and add a prompt describing the change.
- Inpaint a specific area — paint a mask and the masked zone is the only part that gets regenerated. Everything else stays untouched.
- Detail a small area at high quality — turn on detailing to zoom into the masked zone (a face, a hand, an eye) and regenerate it with way more detail than you'd get from a full-image pass.
- Combine multiple reference images — extra slots appear as you connect them, so you can give the model several visual hints to work with.
- Dial each reference separately — turn one reference up or down on its own, or (experimental) send it to a specific area of the canvas.
The node figures out which mode you're using based on what you connect — no setting to flip.
The nodes
| Node | What it does |
|---|---|
| 😺NKD Klein Presampling | The starting point. Model, prompts and reference image go in here. |
| 😺NKD Klein Postsampling | The end point. Delivers the final image and puts everything back after inpainting or detailing. |
| 😺NKD Klein Reference Control | The all-in-one reference dial, and the one to reach for today: strength, an optional per-step curve, and a zone if you give it a mask. optional, experimental |
| 😺NKD Klein Reference Weight | The original strength-only node. Still works; Reference Control does everything it does. optional |
| 😺NKD Klein Reference Region | The regional half on its own, for when a Reference Weight node is already in the chain. optional, experimental |
| 😺NKD Klein Reference Fit | Scales a reference so it sits inside the masked zone instead of stretching across the whole canvas. optional, experimental |
| 😺NKD Klein Prompt Builder | Builds a prompt from your own text plus curated preset dropdowns, with a live preview. optional |
The chain looks like this:
