# ComfyUI Clean Slate Clear connected images and prompts while keeping workflow connections, saved files and prompt history intact. **Release: v0.2.0** · **License: MIT** · **Free local extension** ## Preview ![Clean Slate controller presentation preview](assets/clean-slate-controller.webp) ![Clean Slate connected presentation preview](assets/clean-slate-connected.webp) *Screenshot-based promotional previews. Original screenshots below remain the interface reference.* ![Actual Clean Slate controller](assets/clean-slate-screenshot.webp) ![Actual connected image and paired prompt example](assets/clean-slate-connections.webp) ## Five actions, in order | Button | What it clears | | --- | --- | | Reload All Connections | Connected image selections, mask/latent branch previews and both prompts | | Reload All Connected Images | Connected image selections and image/mask/latent branch previews | | Reload Both Prompts (+ / -) | Both connected active prompt fields | | Reload + Prompt | Connected positive prompt fields only | | Reload - Prompt | Connected negative prompt fields only | “Reload” is the button label. Actions clear selected content and refresh the display; they do not recreate nodes, reconfigure nodes, disconnect wires, execute generation or restart ComfyUI. Every action asks for confirmation first. Cancel or Esc leaves content unchanged; the final OK message reports completion. ## Connections | Input | Count | Connect from | | --- | --- | --- | | image_1–image_5 | 5 | IMAGE outputs of image sources or preview branches | | mask_1–mask_5 | 5 | MASK outputs | | positive / negative | 2 | Matching STRING outputs or separate text-encoder CONDITIONING outputs | | latent / latent_2 | 2 | LATENT outputs, such as KSampler | | control | 1 | Optional control-node output; the controller does not reset its settings | These are additional branches: leave the workflow's existing wires connected. Connecting a latent or processed-image output clears conventional previews on that branch; it does not delete latent tensors. Clearing a processed mask does not erase mask files. A directly connected Load Image source has its current selection cleared. Supports paired `positive`/`negative` fields, standard `text`/`prompt` fields, `text_g`/`text_l`/`text_t5`, and linked text sources/reroutes. Arbitrary third-party field names or conditioning-processing chains may require adapters. ## Install or update 1. Stop ComfyUI. Download the release ZIP and extract `comfyui-clean-slate` into `ComfyUI/custom_nodes/`. Replace the existing files; do not install a second copy. 2. Restart ComfyUI and hard-refresh its browser with Ctrl+F5. 3. Add **Clean Slate Controller** under **RebelTortuga / Utilities**. When updating an old workflow with obsolete sockets, add a fresh controller and reconnect it before removing the old one. 4. Load `examples/ComfyUI-Clean-Slate.json` for a blank image/paired-prompt wiring example. That example also requires [PromptHistory](https://github.com/dawncreatescode/comfyui-PromptHistory). The extension itself has no extra Python dependencies. ## Cleared previews and saved size Cleared conventional image previews stay blank across workflow-tab reconstruction. New execution releases the preview-clear markers so fresh results can appear. Select a new source image before running after clearing. Save the workflow to retain blank values across reopening. The buttons sit above the sockets. Resize the controller as desired and save: tab restoration preserves its saved width and height. ## Fixed image-edit mode node This release also includes **Image Edit Mode (1 Auto / 2 Painted Mask)** (`CleanSlateImageMode`). It has exactly two IMAGE inputs and one IMAGE output: mode 1 selects the automatic result; mode 2 selects the painted-mask composite. Inputs do not grow dynamically. This is used by the [Qwen image-edit workflow](https://github.com/RebelTortuga/comfyui-free-local-qwen-image-edit). ## Validation and limits The author confirmed generation, clearing, Cancel and saved-size behavior in their ComfyUI setup. Isolated tests also cover prompt polarity, tab-restored caches, cancellation, size preservation and image-mode branch selection. A clean-machine GPU installation was not tested. Targets the classic canvas renderer; third-party preview caches and Nodes 2.0 require separate compatibility checks. No saved image files or history files are deleted. Histories stay on each user's machine; no personal images or active prompts are bundled. This is an independent community extension, not an official ComfyUI product. ## 🔗 Related Free RebelTortuga Projects Explore other free tools and workflows: - [comfyui-free-local-qwen-image-edit](https://github.com/RebelTortuga/comfyui-free-local-qwen-image-edit) - [comfyui-free-local-sdxl-inpainting](https://github.com/RebelTortuga/comfyui-free-local-sdxl-inpainting) - [comfyui-free-local-wan-video-quality](https://github.com/RebelTortuga/comfyui-free-local-wan-video-quality) - [comfyui-free-local-wan-video-high-resolution](https://github.com/RebelTortuga/comfyui-free-local-wan-video-high-resolution) [Browse all RebelTortuga projects](https://github.com/RebelTortuga) ## 🐢 Support RebelTortuga Clean Slate is completely free to use.
