Organize your ComfyUI outputs: batch import, compare recipes, and keep the original graph
A folder full of ComfyUI outputs tells you what looked good. Finding which prompts, LoRAs, and settings changed between two experiments can still take work.
I'm the maker of PromptNook, a free MIT-licensed generation recipe library. Try the browser workspace with your existing files, without an account or installation:
Open PromptNook in your browser
1. Import a small batch
Drop in a few original ComfyUI PNGs or workflow JSON files. Use PNGs that still contain their generation metadata; images recompressed or stripped by a sharing platform may not contain it.
Review the prompts, model references, LoRAs, and parameters before saving. Matching generation duplicates are deselected by default, and file errors stay visible. You can still choose to keep a duplicate.
2. Compare two results
Click Compare recipes, choose two entries, and inspect the covers and highlighted setting differences. Only differences helps focus on what changed between experiments. This compares extracted recipe fields rather than every node in the source graph.
3. Keep the graph you imported
Open an imported recipe and choose Export original graph to download its saved snapshot. Imported FLUX and custom-node graphs are preserved too.
Original export doesn't apply later recipe edits or install missing dependencies. Models and custom nodes must be available in ComfyUI; API prompts stay in API format. Building a new graph from edited recipe fields currently supports checkpoint text-to-image.
Keep a backup
The browser library stays in that browser and isn't uploaded to a PromptNook server. Use Settings → Backup & export to keep a copy before clearing site data. The desktop edition also offers local model-folder scanning and desktop backups; download details are on GitHub.

If you try it, I'd love to hear whether your files import correctly and which part of organizing or comparing generations still feels slow.
