Claude Prompt Generator

Most Claude work involves material: a contract, a transcript, a folder of notes you have not pasted yet. The generator writes the surrounding prompt first, leaving a clearly marked place for that material to go — so the instructions stay instructions and never get read as part of the thing being analysed.

Describe the job in your own words. We write the prompt, structured for the model you picked.

How it works

  • 1

    A slot for your material

    The brief is written around content that has not arrived yet, with a labelled section to drop it into when it does.

  • 2

    Boundaries Claude respects

    Tagged sections keep the request separate from the source. On long inputs that separation is what stops an instruction from getting lost in the middle.

  • 3

    Told what to do when it does not know

    The brief asks for "not stated in the document" rather than a plausible-sounding guess, which is the failure that matters when you are working from evidence.

When to use it

  • A review you will run many times

    Same prompt, different contract each month. Writing the brief properly once pays for itself by the third run.

  • Analysis someone else will check

    Explicit rules about citing and hedging make the output auditable rather than merely fluent.

  • Long inputs

    The more you paste, the more the structure matters, and the less you want to have improvised it.

Frequently asked questions

  • Where do I put my document?

    Into the labelled section the generated prompt leaves for it, before you paste the whole thing into Claude. That placement is the point of the structure.

  • What if I want Claude Code instead?

    Pick Claude Code as the target. You get a build-oriented brief — goal, requirements, approach, verification — rather than one aimed at reading and writing.

  • Is this the same as the Claude optimizer?

    No. The optimizer restructures a prompt you already wrote. This writes one from a description, which means it also decides what to ask for, not only how to phrase it.

  • Does it work on Claude's free plan?

    Yes. You are copying text into a chat box; the plan does not change that.
