Prompt Cleaner
Paste a prompt that has grown repetitive or noisy. The cleaner removes duplicate and redundant instructions, strips empty sections and excess blank space, and flags contradictions — without rewriting a word. Runs entirely in your browser.
Paste a prompt with repeated, redundant, or conflicting instructions. The cleaner only removes — it never rewrites or adds.
Cleanup Mode
Safe = only obvious duplicates · Balanced = duplicates + redundancy · Aggressive = also strips filler.

Clean Up a Marketing Prompt
Marketing prompts collect superlatives and restated tone instructions. Here is how to strip them back to the instructions that actually shape the copy.

View Playbook →How it works
Paste a prompt that has grown repetitive or noisy. Pick a cleanup mode — Safe removes only obvious duplicates, Balanced also collapses redundant instructions, and Aggressive additionally strips filler words. Click Clean Prompt to remove duplicate and near-duplicate instructions, repeated tone and length statements, empty sections, and excess blank space. The cleaner never rewrites or adds — it only removes. The Cleanup Report gives your prompt a health score and flags what it can't decide for you: contradictions (like 'keep it short' alongside 'be highly detailed') and ambiguous wording (like 'some examples' or 'as needed'). Everything runs in your browser.
Use cases
- Trimming a system prompt that grew over time by appending fixes and reminders
- Removing the duplicate tone and length instructions that accumulate when several people edit the same prompt
- Catching contradictory instructions before they produce inconsistent AI output
- Shortening a bloated prompt to reduce token cost without losing any actual instruction
Pro tips
- Start with Balanced. It removes redundancy while preserving every distinct instruction. Drop to Safe if you want only exact duplicates gone, or move to Aggressive to also strip filler like 'please' and 'try to'.
- Check the Cleanup Report for contradictions. The cleaner flags conflicts like 'be concise' vs 'be comprehensive' but never picks a winner — that decision is yours.
- Repetition is not emphasis. Saying 'be professional' three different ways doesn't make the model more professional; it just dilutes the other instructions. Collapse them to one.
- Use the Before / After tab to confirm nothing load-bearing was removed before you copy the cleaned prompt.
FAQ
Does Prompt Cleaner rewrite my prompt?
No. It only removes redundancy and flags contradictions. It never rewrites sentences, adds instructions, or changes wording — every line in the output came from your input. That is the difference from a prompt rewriter or optimizer.
How is this different from Prompt Formatter?
Prompt Formatter restructures a prompt into clean sections and formats (Markdown, XML, etc.). Prompt Cleaner does the opposite job: it removes duplicate and redundant instructions and flags conflicts, leaving your structure intact. Use Formatter to organise, Cleaner to declutter.
What do the three cleanup modes do?
Safe Clean removes only obvious, near-identical duplicates. Balanced Clean (the default) also collapses redundant instructions that mean the same thing in different words. Aggressive Clean additionally strips filler and politeness words like 'please' and 'try to'. All three flag contradictions.
Does it detect contradictions?
Yes. It flags common conflicts — length (short vs detailed), tone (professional vs casual), examples (include vs exclude), and explanation (explain vs don't). It shows you both conflicting instructions and leaves the decision to you, since either could be the one you meant.
Will it remove something important?
The cleaner only removes instructions that duplicate or restate one it already kept. Distinct instructions are always preserved. Still, review the Before / After view before using the result — especially after Aggressive Clean.
