MindMap Note Node

MindMap Note Node is the heart of the comfyui_mindmap pack: a sticky note with a separate title and description, wired so it can become part of a knowledge graph. ComfyUI already ships a plain Note node, and Bjornulf's Note added an input and an output so you could build simple graphs out of them. The author of this pack looked at those and built a whole family around the idea - and this note is where it starts.

It's documentation plumbing, not an image node. It never touches a model, never samples, never saves. It exists to make a workflow readable: a two-field card you can drop anywhere to explain what a branch does, why a setting is what it is, or what you were thinking when you built this mess at 2am.

What it does

Two fields in, one socket out:

• title - the heading on the node. Single line.
• description - a multiline text box for the actual note.

The output is an INFO_MAP holding {"title": ..., "description": ...}. The optional info_in input is the clever bit: wire one node's INFO_MAP into the next node's info_in and you get a chain. One note can fan out to several branches, and the graph you draw becomes the mind map. That's the entire trick of this pack - the structure lives in the wires, not in the data. Each node outputs only its own record; info_in is a dependency socket that gives ComfyUI an ordering and gives you a way to connect the tree. So a "knowledge graph" here is literally nodes connected by lines, which is a fittingly literal reading of the phrase.

Install

Same as every node in this pack, because they all ship in one repo:

cd ComfyUI/custom_nodes/
git clone https://github.com/MrAlgion/comfyui_mindmap.git

or search "comfyui_mindmap" in ComfyUI Manager, then restart. Requirements are just requests and beautifulsoup4, both usually already present - the README says so, and the only thing they power is the preview proxy used by the link nodes, not this one. You'll find it in the MindMap category.

When to reach for it

If you just want a floating label, Comfy's core Note does the job and needs nothing installed. You reach for this one when you want the two-field layout - title and body - or when you're building a real map and want the note to participate in the chain rather than sit off to the side.

A quick tip: keep titles short and push the prose into the description. Mind maps get wide fast, and a node with a three-line title is where the layout starts fighting you. And if the nodes ever look cramped, the pack's known-issues section admits that overlapping blocks with buttons get layered margins - so leave breathing room.

One more thing worth knowing: it needs no API key and calls no service. If you're wary of installing random small packs (and given the ecosystem's history, you should be), this one is about as harmless as a custom node gets - a text box that outputs a dict.
