FixMyPrompt is a prompt optimizer and prompt library for ChatGPT, Claude and Gemini. It checks your prompt before you send it, and puts the prompts you already saved one click away. PROMPT OPTIMIZER AND CHECKER Click the floating "Fx" button on ChatGPT, Claude, Gemini, Perplexity or Grok. The prompt checker gives you: • A score out of 100 • The problems in your prompt, ranked by how much they matter, each with a fix • A rewritten prompt you can apply with one click It works as a prompt enhancer and prompt improver for any prompt you type, from emails to code to research. YOUR PROMPT LIBRARY, IN THE CHAT BOX Sign in and open "Saved" on ChatGPT, Claude or Gemini to see your saved prompts and memories from FixMyPrompt. Search them, pick one, and it goes into the chat box. Saved prompts work like prompt templates: if a prompt has blanks, such as a client's name, you fill them in first. Nothing is sent until you press send. It's a prompt manager that lives where you write. Memories are what your AI worked out before: the steps, the commands, how to check it worked. You save them from Claude Code, Codex, Cursor or fixmyprompt.net. Before anything is stored, FixMyPrompt checks it for passwords, keys and other secrets.
