Installation

Clone into your ComfyUI custom_nodes directory and restart ComfyUI:

cd ComfyUI/custom_nodes
git clone https://github.com/Little-God1983/ComfyUI-AI2Go-Utils

No extra dependencies (it uses Pillow, already shipped with ComfyUI). It can coexist with ComfyUI-KJNodes — both Ideogram 4 nodes run side by side without conflict.

Nodes

AI2Go Ideogram 4 Prompt Builder

A visual prompt builder for Ideogram 4's structured JSON caption format. Draw bounding-box regions on a canvas, describe each one, and the node assembles the caption — with a full scene-graph Overview, region parenting, and named groups layered on top.

Outputs: prompt (the caption JSON), preview (a rendered overlay image), bboxes (pixel-space boxes for SAM3 / crop nodes), width, height.

Region editor (canvas)

• Draw by dragging; move and resize with handles; Ctrl-drag to force-draw over an existing box.
• Per-region type (object / text), description, verbatim text, and a color palette; editable bbox fields (pixels + the 0–1000 grid).
• Multi-select — shift-drag marquee, shift-click toggle; Alt-click cycles overlapping boxes; Del / Ctrl+C·V·D to remove / copy / paste / duplicate.
• Lock regions, composition guides (thirds / grid / golden ratio / spiral), snap-to-grid, and adjustable label & box styling.
• Background: a connected reference image, the last generated image ("Grab BG"), or the live sampling preview — with a brightness control.
• Dockable / pinnable / fullscreen panel, a live token estimate, and output settings (compact/pretty JSON, normalized/absolute coords, yx/xy bbox order).

Overview (scene tree)

• A persistent, collapsible panel listing every region — click a row to select it (synced both ways with the canvas), so you can pick and edit a region without nudging it.
• Ctrl/Cmd-click to multi-select, Shift-click for a range.
• Lock, duplicate, and delete from the list; drag a row — or a whole multi-selection — onto another to nest it; drop on the header to send back to root.

Parenting & groups

• Parent any region under another: move a parent on the canvas and its children follow. Deleting a parent promotes its children to the grandparent (no surprise subtree wipe).
• Groups — right-click the Overview → Create group from selection to wrap regions in a named container:
  • Move the group → everything moves; resize the group → its members scale.
  • Duplicate the whole group, or mirror its members horizontally / vertically.
  • Deleting a group keeps its children.
  • Groups are editor-only organizers — never part of the exported prompt. Toggle their frames on the canvas with 👁️ (hidden by default; always listed in the Overview).

Copy / paste & interop

• Copy / Paste the caption JSON, and save/load named Templates (stored server-side).
• Copies carry a small _ai2go sidecar that preserves the full layout (groups + hierarchy) for a lossless AI2Go → AI2Go round-trip, while staying two-way compatible with ComfyUI-KJNodes: KJNodes ignores the extra data and loads the flat scene, and KJNodes captions load here flat too. The sidecar never reaches the model prompt.
