Someone in r/ChatGPTPromptGenius built a tool called Prompt Vault, and it’s aimed at the actual reason most AI outputs are trash: the prompt was bad, not the model.
What’s new: it’s not another “generate a prompt from an idea” tool, though it does that too. The bigger piece is the fixer. You paste in a weak prompt, the one giving you generic mush, and it rebuilds the structure, adds the missing context, and tightens the vague phrasing without changing what you were actually trying to do.
The twist is in step two. Every {{variable}} or [bracket] you dropped into a prompt template becomes a live fill-in field. That’s the part that actually saves time. You’re not manually hunting through paragraphs to swap [Company_Name] and breaking the syntax by accident. You fill a form, it snaps the prompt back together clean, done.
Here’s the mini workflow:
- Paste your weak prompt into the fixer
- Let it flag the vague spots and rebuild the structure
- Turn any bracket or variable into a fillable field
- One-click launch straight into ChatGPT, Claude, Gemini, or Midjourney
Pro tip: run your best prompts through the fixer too, not just the bad ones. Even prompts that already work usually have one constraint you never wrote down, and that’s the thing quietly wrecking your output on edge cases.
Second pro tip: there’s a public gallery on the homepage with pre-built templates, and you don’t need an account to try it. Test it on a real prompt before deciding if it earns a login.
Go break your worst prompt on it: prompt-vault.net 🛠️
Stop getting vague Al responses and wasting your tokens trying to fix your prompts.
