ComfyUI Text Preset Loader

ComfyUI text preset loader

while using comfyui I found my self switching between group of texts either for my favourite art styles or characters.

Features

• Load text presets from JSON
• Switch between different text presets
• Edit and save new text presets
• optional preview image for each preset
• Tree structure for presets to organize them in categories and subcategories
• search function to quickly find presets by name
• Responsive browser library at /preset_loader/browse
• Category navigation, breadcrumbs, pinned presets, favourite presets and recent presets
• Live synchronization between the browser library and canvas nodes
• Safe atomic JSON updates, rename/move, and save-copy support
• Responsive preset editor with preview upload and draft protection
• Pick presets by ID from a workflow input, with random and range selection

Usage

1. load Preset Loader Node from Node library
2. in the drop-down menu choose between your text presets
3. the text preset will be loaded in the string box and the image will be shown in the image box if it exists
4. you can edit the text in the string box and save it as a new preset by clicking the save button and giving it a name.
5. the new preset will be added to the drop-down menu and can be loaded like the other presets.
6. you can also delete presets by clicking the delete button on the node.
7. you can save preview image for the preset by clicking the save image button and selecting an image file.

Browser library

Open http://localhost:8188/preset_loader/browse (replace the host and port if needed) to manage presets in a full-page interface. The library supports desktop and mobile layouts, category browsing, search, pinned, favourite and recent presets, preview images, rename/move, and live updates to open ComfyUI nodes.

Preset names use / as a category separator, for example:

Characters/Heroes/example
Camera/Portrait/close_up

Picking presets by ID

Every preset has a positional ID at each level of the tree, shown next to its name in the browser. Read them down the tree — the first group is 1, the first preset inside it is 1, and so on — so 1,2,1 means group 1, subgroup 2, preset 1.

The node has two optional inputs for this (connect a node to use them; leave them unwired and the node behaves normally):

• preset_id — a string that selects a preset by its numbers.
• seed — drives the random forms below. The same seed always resolves to the same preset, so a result you like is reproducible. Wire an Int node set to randomize to pick a different preset each run.

preset_id overrides the dropdown and the text box when it is connected.

| input | picks | | --- | --- | | 1,2,1 | group 1, subgroup 2, preset 1 | | 1,2 | first preset under group 1, subgroup 2 (unspecified levels take the first) | | 1,,3 | an empty level also takes the first entry | | 1,1,[3:8] | a random preset with an ID from 3 to 8 | | 1,1,[1:-1] | any preset at that level (-1 means the last one) | | 1,1,[1,4,6] | a random pick from that list |

If a number doesn't exist it falls back to the first entry at that level rather than failing, and ranges are trimmed to what actually exists, so [3:99] with 7 presets picks between 3 and 7.

Note: IDs are positional. Adding or deleting a preset shifts the numbers of the ones after it in the same group, so a workflow that hardcodes an ID may point at a different preset later. This suits sorting and random picking rather than a permanent address for one specific preset.

Editing behavior

• Update overwrites the currently selected preset and is enabled only when its text has changed.
• Save copy creates a new preset from the current text and preserves the selected preset's preview image.
• Rename/move, pin/unpin, favourite/unfavourite, and delete are available from the node's actions menu.
• Browser edits, pin changes, and favourite changes are propagated to open nodes without reloading.

usage in workflow

1. connect the output of the Preset Loader Node to the input of a Text concatenate Node.
2. use the other input of the Text concatenate Node to add any additional text you want to include in your prompt.
3. connect the output of the Text concatenate Node as text for CLIP text encode node.
4. use the output of the CLIP text encode node as usual.

What's new in 2.1.0

• Favourite presets (♥) — mark your most-used presets per category. Unlike pinning, favouriting doesn't pull a preset out into its own list: it stays right where it is in the tree, just sorted first and marked with a heart, so categories stay meaningful while your go-to presets still rise to the top.
• Pin and favourite are now separate, independent toggles with their own icons — 📌 for pin, ♥ for favourite — available from the node's actions menu and from the browser library (card corner buttons and the editor drawer).
• Favouriting does not change a preset's preset_id number — those stay purely alphabetical, so existing workflows that hardcode an ID are unaffected.
• Existing user_presets.json files are migrated automatically on first load after updating — no manual edits needed, and nothing gets overwritten.

Notes

• tested it a little bit with nodes 2.0 seems to work. but it was designed for classic.
• I have allergy for JS, so I am sorry if there is something not accounted for.
• To save new preset rather than overwrite just change the name after hitting the save as button.
• remember to use / to create categories and subcategories in the preset name.
• the node comes with 7 presets for testing in flux, you can delete them if you want or edit them as you like.

acknowledgements

• Claude Sonnet 4.6 from Anthropic.
• Huge thanks to @Samseys for an amazing contribution — the responsive preset browser, the in-node browser with categories and search, per-node preview controls, multi-frontend support with the /preset_loader/browse manager, live synchronization between the browser and open nodes, and the atomic, lock-protected JSON writes that make it all safe. This release is built on that work.
