Note

Because sometimes your future self needs a Post-It too.

🧠 What This Node Does​

The Note node is a pure utility node in ComfyUI that serves one humble but essential purpose: letting you insert freeform text notes directly inside your workflow. This text can be used for labeling, documentation, reminders, or snarky messages to your teammates. It does not affect the execution of the graph in any way—no inputs, no outputs, no side effects. It’s just a textbox. And sometimes, that’s exactly what you need.

🧩 Node Type​

  • Category: Utility
  • Type: Annotation / Documentation
  • Execution: Skipped at runtime

🔌 Inputs​

  • None. The Note node is a true loner. It doesn’t accept or need any inputs.

🔁 Outputs​

  • None. This node doesn’t output anything either. Not even a high five.

⚙️ Parameters & Fields​

FieldTypeDescription
notestring (multiline text)The content of your note. You can write anything here—markdown, plain text, sarcastic reminders to yourself, TODOs, or even ASCII art if you’re feeling frisky. There’s no formatting enforcement. Just type your heart out.

✅ Real-World Use Cases​

  • Workflow Documentation: Label each section of your graph to describe what it’s doing. Future you (and anyone else looking at the workflow) will be grateful.
  • Testing Notes: Leave yourself notes when comparing different models or parameters.
  • Workflow Debugging: Write out what you think is happening vs what is actually happening.
  • Collaboration: Add instructions or context for others who might use or modify your workflow.
  • Reminders: Need to update the model? Replace a VAE? Add a watermark? Just write it here and stop forgetting.

🧪 Workflow Setup Example​

You don’t connect this node to anything, which means setup is stupidly simple:

  1. Drag the Note node into your workflow.
  2. Double-click the note field or open the properties panel.
  3. Type whatever message you want to leave.
  4. Close the panel. That’s it.

Repeat as needed across your workflow like it’s a crime scene covered in yellow sticky notes.

💬 Prompting Tips​

  • Not applicable. This node doesn't interact with prompts.
  • But if you must, you can leave suggested prompts inside your note field as references for future prompt engineering.

🔥 What-Not-To-Do-Unless-You-Want-A-Fire​

  • Don’t try to wire this node to anything. Seriously. It has no ports.
  • Don’t expect it to do anything during execution—it won’t.
  • Don’t rely on this as a secure form of documentation for sharing workflows online. Some frontend variants or exports may skip utility-only nodes when compressing workflows.

⚠️ Known Issues​

  • Some user interfaces may collapse or minimize the note field, making it easy to miss.
  • Notes do not currently support rich text, markdown rendering, or hyperlinks.
  • If you’re working on massive workflows, the node might become buried in a sea of chaos—consider color-coding your sections using dummy nodes or labels if your frontend allows it.

📝 Final Thoughts​

The Note node is the unsung hero of workflow sanity. It won’t render an image, run a model, or sample anything, but it will make your life easier. It’s the “narrator” of your workflow, and a place to add clarity in a world full of latent_image spaghetti.

So go ahead—drop a few notes. Your brain will thank you later.
