Fix my prompt
Updated July 2026
If the AI keeps giving you the wrong thing, the prompt is usually the problem. PromptDC adds the goal, context, constraints, and output format the model needs. See the example below, then select a prompt anywhere on the web to fix it in one click.
Before and after
make a landing page. it should look good and convert
Build a single-page landing page for a productivity SaaS aimed at indie developers. Sections in order: hero (headline + subhead + email capture), 3 feature cards, a short testimonial, pricing (one $9/mo plan), and a footer. Use a clean, high-contrast light theme, system font, and mobile-first layout. Return semantic HTML + minimal inline CSS.
Plans from $9/mo, or Lifetime from $69 with your own API key.
The most common prompt failures are vagueness (the model doesn't know what 'good' means), missing context (it can't see what you can), and no format (you get an essay when you wanted a list). PromptDC repairs all three on selected text anywhere, and rewrites editable prompts in place.
Frequently asked questions
Why isn't my prompt working?
Usually it's too vague, missing context the model can't infer, or has no requested output format. PromptDC rewrites the prompt to add those, which is what turns unreliable answers into consistent ones.
Is 'fix my prompt' free?
No — PromptDC is a paid tool. This page shows example fixes. Fixing your own prompts happens in the PromptDC extension — Pro at $9/mo, Enterprise at $15/mo for higher limits, or a one-time Lifetime plan (from $69) with your own API key.
Does it work for coding prompts?
Yes. For code, PromptDC's Coding mode rewrites vague requests into precise, implementation-ready specs. See the Cursor prompt generator for a coding-specific version.
