Load Prompts From File (Inspire)

Write a list of prompts in a text file, point this node at it, and it feeds them into your workflow one after another - the node for batch-generating a whole set of prompts without babysitting the queue. Each prompt in the file becomes an entry in a list, and because ComfyUI iterates over lists, your graph runs once per prompt. Great for churning through a prompt sheet overnight or generating a themed set.

The file format is simple: one file can hold multiple prompts separated by a line with ---, and each prompt can have a positive and negative part plus a name. The node reads them into ZIPPED_PROMPT entries - Inspire's little container that bundles positive, negative, and name together - which you then split with Unzip Prompt (Inspire) before wiring into your encoder and sampler.

How it works

It reads the chosen prompt file, splits it on the --- separators, and emits the results as a ZIPPED_PROMPT list. ComfyUI's list execution then runs the downstream nodes once per prompt. Alongside the list it returns a count (how many prompts loaded) and remaining_count, so you can drive logic off how many are left. Pair it with Unzip Prompt to pull out the positive/negative/name for each entry.

The inputs and outputs that matter

• prompt_file - the file to read (the dropdown lists files under the pack's prompts/ directory).
• start_index - skip the first N prompts; use it to resume a batch you stopped partway.
• load_cap - cap how many prompts to load (0 = all); handy for a test run of the first few.
• text_data_opt (optional) - pass prompt text in directly instead of from a file.

Outputs: zipped_prompt (list), count, and remaining_count.

Installing it

ComfyUI Manager: search "Inspire Pack", install, restart. Manually:

cd ComfyUI/custom_nodes
git clone https://github.com/ltdrdata/ComfyUI-Inspire-Pack

Then restart (pip install -r requirements.txt if you cloned by hand).

Where people get tripped up

The prompt_file dropdown reads from a specific place - files under ComfyUI-Inspire-Pack/prompts/ (the README notes you can also register an inspire_prompts path in extra_model_paths.yaml). Drop a .txt somewhere random and it won't appear in the list; put it in the prompts folder and restart or refresh. Second snag is the plumbing: the output is a ZIPPED_PROMPT, not text - you have to run it through Unzip Prompt (Inspire) to get usable positive/negative strings, and forgetting that step is the most common "why won't this connect" moment. And since this produces a list, the whole downstream graph iterates - that's the feature, but it means every node after it runs once per prompt, so size your batch with that in mind.
