Why not just ask ChatGPT or Claude?

You can. A blank chat box is just where mediocre output starts.

Tested, not improvised

Each prompt comes from someone who already used it for real work. The structure, constraints and output format are the result of trial and error you don't have to repeat.

Structured, with placeholders

Fill in [CLIENT], [KEY METRICS], [DEADLINE] and go. You bring the facts; the template supplies the steps, tone, format and what to leave out.

Tuned for your model

Claude likes XML-style tags, ChatGPT likes a role and steps, Gemini likes labelled context. One click adapts any prompt to the AI you use.

Community-vetted

Every submission is reviewed before it goes live, then upvoted and copied by people who use it. What's useful rises to the top.

Saves the trial and error

Skip five rounds of "make it shorter, make it sharper". Start from the version that already worked on a deck, a hard email or a pitch.

Private by design

Prompts are published with placeholders instead of client names or numbers, so you can share what works without sharing what's confidential.

Step two

Tune a prompt for your AI

Adapt any prompt to your model. Pick your AI and a task, or choose “My own rough prompt” and paste one (or use Tune for my model on any library prompt).

1. Pick your AI

2. Pick a task

3. Quick context

🔒 Use placeholders like [CLIENT]. We don't store your inputs.

How we handle your text

Plain answers, no fine print.

Sent to an AI providerWhen you tune a prompt, your text is sent through the Codegraff gateway to an AI model to produce the result.
We don't store tuner inputsUnless you press Save while signed in, what you type into the tuner isn't kept.
We don't train modelsChatJudge doesn't train models on your inputs. Use [PLACEHOLDERS] instead of real customer data.
Free, with sponsorsThe site is free and supported by sponsors and affiliate links, always labelled.
