Output Grader

Paste what you asked for and what the model gave back. It scores the output out of 100 against your requirements — required content, length, format — and against eight tells of a padded answer, then writes the follow-up prompt that fixes exactly what it found.

One per line. The tool checks each one literally — it is looking for the words, not the meaning, so use the term you expect to see.

    Nothing leaves your browser. This checks structure and tells, not meaning — a human still has to read it.
    

    




    How it works
    

      

    • Your must-include list is checked literally, so use the words you expect to see.
      • 

    • Format is checked structurally: a markdown table, a list, valid JSON, headings, prose or a code block.
      • 

    • Eight tells are detected: filler openers, AI vocabulary, heavy hedging, vague quantifiers, closing padding, capability disclaimers, repetition, and restating your own brief.
      • 

    • The fix prompt lists only the problems it found and tells the model to change nothing else.
      • 

    

    What it does not do
    

    Every tool on this site says this plainly, because a tool that pretends to do more than it does costs you more than it saves.
    

      

    • It checks structure and surface tells. It cannot check whether the content is true — that is still your job, and it is the part that matters most.
      • 

    • A high score means the output is well formed, not that it is right.
      • 

    • The tells are English-language patterns.
      • 

    

    

    Nothing you type here leaves your browser
    

    There is no account, no server and no logging. The whole tool is JavaScript running on your own machine — close the tab and it is gone. You can check: open your browser’s network tab and use it.
    

    

    Questions people ask
    

    

    Why does AI writing sound like AI writing?
    Filler openers, hedging on every sentence, vague quantifiers and a closing summary nobody asked for. Those four account for most of it, and all four are fixable in the prompt.
    

    

    What score should I aim for?
    Above about 78 means nothing structural is wrong. Below 50 means send it back — and the tool gives you the prompt to send.
