Getting started
FixMyPrompt checks a prompt before you send it, and keeps what your AI worked out so it can follow the same steps next time.
Make an account
A free account connects 1 AI tool, keeps up to 25 memories, and your AI can read them 300 times a month. Pro is $19 a month after a 7-day free trial, with 20,000 credits every month.
Three things to try first
- Open the app, paste a prompt and press Score. Then press Fix it to get better versions.
- Connect Claude Code or Codex, so your AI can check prompts and save memories while you work.
- Add the Chrome extension, so you can check a prompt on ChatGPT, Claude or Gemini before you send it.
Words you'll see
A memory is what your AI worked out: the steps, how to check they worked and what to avoid. A project holds the memories for one folder or piece of work. Credits pay for checks and rewrites.
Using the app
The app at fixmyprompt.net/app is where you check prompts, save them and look after your memories.
Check and fix a prompt
- Press New chat and paste your prompt.
- Press Score to see how clear it is, from 0 to 100, and what to fix.
- Press Fix it for better versions. Below 80 the app suggests this next.
- Press Try it to see the AI's reply, or Compare to see the replies to your old and new prompt side by side.
- Press Make it shorter to cut words the AI doesn't need.
Save it
Press Save, name the prompt and pick a folder. If you opened a saved prompt, you can save a new version of it or a new prompt.
Memories
Memories shows everything you saved, with a tab for each project. A project can have sub-projects, so a big project stays sorted. Open a memory to see its versions, how often it was used and whether it worked.
Library
Library holds ready-made prompts for your kind of work. Pick one, fill in the blanks and use it. Part of Pro.
Context
Context holds the rules your AI should always follow: your company's, your role's and your own. Your AI loads them at the start of a chat. Part of Pro.
Find anything
Press Cmd+K on a Mac or Ctrl+K on Windows to search your chats, projects and memories. Cmd+\ or Ctrl+\ hides and shows the side panel.
Settings
Open Settings at the bottom of the side panel. Profile, Appearance, GitHub checks, Model and API key, MCP connections, Usage and credits, and Billing and plan are all there. Company accounts also get Members, Teams and Company.
Use FixMyPrompt inside your AI tool
Connect Claude Code or Codex once. Then ask your AI in plain words and it uses the FixMyPrompt tools for you.
Connect Claude Code
Run this in a terminal. Claude Code asks you to sign in the first time it uses FixMyPrompt.
claude mcp add --transport http fmp https://fixmyprompt.net/api/mcpConnect Codex
Run this in a terminal. Codex opens FixMyPrompt in your browser so you can approve the connection.
codex mcp add fmp --url https://fixmyprompt.net/api/mcpOther AI tools
Paste this address where your tool asks for a remote MCP server. Your link is also in the app under Settings, MCP connections.
https://fixmyprompt.net/api/mcpThings to ask
- "Use fmp to score this prompt."
- "Save what we just worked out as an fmp memory."
- "Use fmp to find how we deploy staging."
On Free you connect 1 AI tool and your AI can read memories 300 times a month. Tools marked "uses credits" spend credits each time they run.
All the tools
You don't need to know these names. Your AI picks the right tool when you ask in plain words.

Your AI calls it when you start work in a folder.report_memRecords whether a memory worked. A failed one stays marked until a new version fixes it.
Keep memories tidy

Rules and notes

The Chrome extension
Check a prompt on ChatGPT, Claude, Gemini, Perplexity and Grok before you send it, and drop in prompts you saved.
Check a prompt
- Add FixMyPrompt from the link below and pin it to the toolbar. Other extensions in the store share the name, so use this link to get ours.
- Open ChatGPT, Claude, Gemini, Perplexity and Grok and type a prompt, but don't send it yet.
- Click the floating Fx button. You get a score, what to fix and a rewrite you can apply in one click.
Without an account you get 3 checks a day on each device.
Sign in
Click the extension icon, then Sign in. A FixMyPrompt tab opens. Sign in there if you need to, then press Approve. The extension shows you as signed in within a few seconds.
Use a saved prompt
On ChatGPT, Claude or Gemini, click Saved in the panel, or click Fx with the chat box empty. Pick a project from the list to see its prompts grouped by sub-project, then pick one. If it has blanks, fill them in. It goes into the chat box and nothing is sent until you press send.
What gets sent
The extension sends your prompt only when you click Fx, and reads your saved items only when you open Saved. Checks you run while signed in are saved to your report history.
