The free AI prompt enhancer that fixes vague prompts in one click.
AI Prompt Enhancer (by AI Prompt Fixer) scores and rewrites your prompts in real time inside ChatGPT, Claude, Gemini, Perplexity, VS Code and Cursor. Type, pause, and get a sharper prompt — without ever leaving the chat.
Most prompts fail before the model even reads them.
The single biggest reason ChatGPT, Claude or Gemini gives a flat answer is not the model — it is the prompt. A great AI prompt enhancer fixes that gap by adding structure, intent, audience and constraints automatically, so the model has everything it needs to reply well on the first try.
Real-time prompt scoring
A 1–5 maturity score appears beside every chat input the moment you stop typing. See clarity, specificity and constraint sub-scores at a glance.
One-click rewrites
The enhancer turns vague prompts into sharp, structured prompts that include audience, format, constraints and success criteria — without losing your voice.
Sub-second responses
A 120-entry LRU cache and a complexity-aware router pick the fastest healthy model, so most rewrites land in under a second.
Private by design
Prompts are processed in-memory to score the current request, then dropped. No training on your data. No sharing with third parties.
Conversation-aware
The enhancer reads up to the last 6 turns of context from the page DOM so a follow-up like “make it shorter” still rewrites with the full thread in mind.
Works in every major AI chat
Native support for ChatGPT, Claude, Gemini and Perplexity in the browser, plus a first-class extension for VS Code and Cursor.
From a sentence to a brief.
Real examples of how the AI prompt enhancer turns a flat prompt into one that gives the model something to work with.
