💰 Sunday Bonus #71: Turn vague requests into polished prompts with Prompt Crafter

This week, I thought: “Wouldn’t it be cool to have a tool that incorporates these lessons and helps someone turn their initial ask into a fleshed-out prompt?”

So then I went and made one, because I’m a doer, dammit!

Say hello to Prompt Crafter.

This Claude Artifact takes your half-baked idea, interviews you, and spits out a complete prompt to use with your favorite chatbot.

Here’s how it works:

  • Step 1: You type in your rough request.

  • Step 2: Claude asks you follow-up questions tailored to your situation.

  • Step 3: Claude drafts a structured prompt using the CRAFT framework (Context, Role, Action, Format, Tone). You can review and tweak it.

  • Step 4: Claude provides a formatted version you can copy or save as a text file.

Here it is in action:

Note: Using the Prompt Crafter requires a free Claude account. If you don’t feel like making one, I’ll also share my custom GPT that does largely the same thing via chat.

Here you go:
