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.
