What this tool does
This is mechanical formatting. It will not synonym-swap, translate, or ‘improve’ a prompt. That keeps it local and predictable.
How to use it
- Paste a prompt.
- Copy the cleaned text.
- Keep a copy of the original if spacing was meaningful to you.
Supported input
- UTF-8 text up to 2 MB
Output
- Cleaned prompt text

soft light, , portrait of Ada , film grain
soft light, portrait of Ada, film grain
Troubleshooting
- A meaningful double comma vanished
- The cleaner collapses repeated commas. Undo with the original text; there is no cloud history.
FAQ

No. <lora:name:1> stays.
Can it split positive and negative prompts?
Not automatically. Use the prompt-to-JSON tool if you want tokens as data.
Does it upload prompts?
No.
