How a tighter prompt cuts your AI bill
A vague prompt forces the model to guess at audience, format, and tone, then fill those gaps with generic boilerplate you have to delete or rerun. Every retry costs the full generation. FixMyPrompt's QA rubric flags the specific weak spots before you spend the call.
Better First-Attempt Success
Our QA catches vague language and missing constraints before you spend tokens.
Fewer Revision Loops
Outstanding prompts mean you rarely need to re-run or tweak the same request.
Sharper, Smarter Prompts
Structured goals, clear roles, and measurable outcomes = efficient token usage.
Where the numbers come from
The savings range users see depends on workload. Two specific mechanisms drive almost all of it. First, killing the retry cycle: a prompt that produces a usable answer first time costs one generation; a prompt that needs three rewrites costs four. Second, stripping the sycophant filler that pads responses by 50-200 tokens each. We documented the mechanics here:
Prompt QA that feels premium

FixMyPrompt started because Tim (a.k.a. Chewy) kept losing time and money on AI prompts that simply did not work. He was using ChatGPT and Claude daily for development and content work, and he noticed a pattern: most failures came down to the same handful of mistakes. Vague goals. Missing context. No output format. Wrong tone for the model.
Rather than keep guessing, he built a QA engine that checks prompts before they hit the model. It analyzes your input against proven patterns, surfaces what is missing, and rewrites the prompt so the first attempt actually lands.
The savings come from a simple mechanism: a prompt that lands the first time costs one generation; a prompt that needs three rewrites costs four. Cleaner prompts move the model from guessing to executing. The wins compound across long sessions because the sycophant filler and retry cycles add up.
How it works
Paste your prompt. The QA engine runs real-time analysis and returns a scored report with specific issues flagged, the reasoning behind each one, and a rewritten version you can use immediately. Works with ChatGPT, Claude, Gemini, Midjourney, and anything else that takes a text prompt.
