Gemini Prompt Optimizer

Gemini responds well to short, clearly labelled blocks — Role, Task, Context, Constraints, Output — and to being told exactly what shape the answer should take. This optimizer produces that structure and scores the result for Gemini.

How it works

  • 1

    Bold labels, short blocks

    Each section gets a bold label and stays compact, which suits how Gemini parses instructions.

  • 2

    The output shape is stated

    Tables, bullet counts, word limits. Being explicit about the shape is what stops an answer sprawling.

  • 3

    Scored for Gemini

    Model fit rewards this labelled structure. The same input produces XML for Claude and Markdown headings for ChatGPT.

When to use it

  • Research and comparison tasks

    Comparisons need stated criteria. The optimizer pulls them into a constraints section so every option is judged the same way.

  • Planning and calendars

    Say the period, the cadence and the columns you want, and you get a plan instead of an essay about planning.

  • Explaining numbers to a mixed audience

    Stating the audience and the reading level changes the answer more than any other single edit.

Frequently asked questions

  • Does this work with Gemini in Google Workspace?

    Yes — the result is plain text. Paste it wherever you use Gemini, including inside Workspace apps.

  • Can I use it for image prompts?

    Not while Gemini is selected: its labelled blocks are meant for instructions, and an image model wants qualities. Switch the target to Midjourney and you get the flag-based syntax those tools expect.

  • Why is the structure different from the ChatGPT page?

    Because the models are different. Our optimizer produces the parts of a prompt, then renders them in each model's conventional syntax — that is the whole point of choosing a target.

  • Is there a limit?

    20 optimizations a month on a free account. Scoring is unlimited and needs no account.
