Prompt Fixer
An editor for your AI prompts — see exactly what's missing
I kept writing lazy prompts and blaming the AI for bad answers — so I built an editor for my prompts. Prompt Fixer marks up your ChatGPT/Claude prompt like a real editor would — showing exactly what's missing (role, context, format, tone, audience, constraints) with a before/after score and clickable annotations explaining each fix. Rule-based, not an LLM wrapper — instant, free, no sign-up. Paste, fix, copy. Built after one too many "write me an email" prompts that got me nothing useful.
I'm Owais — I've been building freelance data/dashboard work on the side, and along the way I noticed I was constantly writing lazy prompts into ChatGPT and Claude, then getting annoyed when the answers came back generic. Eventually I realized the problem was usually my prompt, not the model.
So I built Prompt Fixer: paste in what you were about to send, and it marks it up like a real editor would — showing exactly what's missing (role, context, format, tone, audience, constraints), with a before/after score and clickable annotations explaining why each addition helps, not just a black-box "here's a better version."
It's fully rule-based, not another LLM API wrapper — so it's instant, free, and there's nothing hidden about how it works.
Would genuinely love feedback, especially:
Does the redline/annotation format actually help, or is a plain rewrite enough?
Any prompt categories I'm missing (I've got general/writing/coding/business/study/image right now)?
Thanks for checking it out
