Pro tips
- Weights like (bad anatomy:1.3) tell the model how hard to push each exclusion.
- Paste straight into the negative-prompt field on CivitAI or Automatic1111.
- Name a specific failure you keep seeing and the tool weights it up.
- Reuse one strong negative across a whole batch for consistent results.
