📦 ComfyUI-E-Tier-TextSaver
Sick of annoying tokens messing up your prompts? 😂 This one’s for you.
A secure and flexible text-saving node for ComfyUI.
After captioning with Florence2 or similar, it automatically strips unwanted tokens and saves a clean .txt file.
✨ Key Features
- ✅ Removes unwanted tokens like
<pad>from caption text - 🔐 Strict path validation and filename sanitization
- 🧩 Works smoothly with Florence/BLIP captioning nodes
- 📂 Supports LoRA-style image-text dataset workflows
🧑💻 Use Case Example
When training LoRA models, it's common to need .txt caption files that match image filenames.
This node makes that easy by fitting naturally into a workflow like this:
[Image Loader] ➡️ [Captioning Node] ➡️ [Text Saver (E-Tier)]
🔐 Security Design
All save paths go through strict validation checks:
| ✅ Allowed | ❌ Blocked |
|---|---|
| Existing directories only | Non-existent paths (no auto-creation) |
| Absolute paths | Relative traversal (e.g., ../) |
| Safe characters | Shell/metacharacters (e.g., ` |
| Clean text input | Suspicious patterns (e.g., eval, <script>, etc.) |
📌 The final save path is clearly printed to the console for full transparency.
⚙️ Node Parameters
| Parameter | Description |
|---|---|
text |
The text content to be saved (required) |
filename |
Filename for the resulting .txt file (required) |
save_to |
Output directory selected from a dropdown list |
About the save_to Parameter
The save_to dropdown paths are specified in the node's YAML whitelist file. Users can set custom keys (names) and their corresponding directory paths in the YAML whitelist like this:
whitelist:
ComfyUI/output: "./ComfyUI/output"
CustomFolder: "./my_custom_output"
Here, "CustomFolder" is the label shown in the dropdown, and "./my_custom_output" is the actual directory path used for saving files.
This allows flexible and user-friendly naming of output locations.
❗ Other Notes
- Any validation errors will be clearly displayed in the console or UI.
- If no filename is given, it defaults to
"untitled.txt". - This node will not create directories — make sure your structure exists.
- Secure by default, but configurable for advanced users.
