Prompt diet

What it is

Prompt diet rewrites a prompt so it asks for the same result in fewer words. Every requirement, constraint, name, number and output format you wrote stays. Greetings, repeats and polite padding go. On a prompt that goes out with every call, the saving repeats each time.

1. You paste the prompt, with yours in place of {{input}}
2. The chat’s model rewrites it under the skill’s rules
3. The short prompt comes back with a word count

Who it suits

Anyone who pays per token or keeps running into a context limit. The more often one prompt goes out, the more a shorter version pays back.

If you only ask short one-off questions, skip it.

Where to use it

In any AI chat, before a long prompt goes to a paid model. It earns its keep on prompts you send again and again.

• Any AI chat: ChatGPT, Claude, Gemini or another, where you paste the skill’s prompt and yours
• Wherever the prompt lives: an agent’s settings, a script, a shared document or another chat app, as long as you can copy the text
• Wherever it goes next: paste the short version back where the long one was

How to set it up

What you need first:

• Where it runs: any AI chat
• A key: none
• Cost: nothing beyond the chat’s own model

1. Sign in to Mindket and press Get it on this listing.
2. In your Mindket account, View shows the prompt to read and copy. This page shows it too.
3. Keep it where you can paste it again: a saved prompt in your chat app, if it keeps them, or a note.

How to use it

Paste the skill’s prompt into the chat and put the prompt you want trimmed where it says {{input}}.

<the skill’s prompt>
<paste your prompt here, in place of {{input}}>

• What comes back: the rewritten prompt, then one line with the word counts before and after
• Before you reuse it: read the short version, and put back any word you need

Example

A polite request for a summary, pasted in place of {{input}}.

Hello, I hope you are well. If it is no trouble, could you please write a short summary of the article below, under 100 words, and mention the author and the date. Thank you so much.

Back comes something in this shape, not a saved run. The word counts are the model’s own estimate.

Summarize the article below in under 100 words. Name its author and date.
About 36 words before, 13 after.

Every requirement made it through: the limit of 100 words, the author and the date. Only the courtesy around them was cut.

For newcomers and experts

If you are new. An AI model reads every word you send, and paid models charge for those words. Prompt diet keeps your instructions and drops the padding around them. Try it first on a request you sent an AI last week. Then check that the short version still asks for everything.

For experts. It is one prompt template run by whichever model the chat uses, so what counts as filler is that model’s call. Constraints, names, numbers and formats are kept by instruction, not by parsing. Cutting words can also cut the repetition some models lean on for tone, or the few-shot examples that anchor a format. The word counts come from the same model, not a tokenizer. Test the short prompt on your own evals before you swap it in.

Good to know

• Word choice: it cannot tell which words your model relies on, so read the short version where tone or a worked example matters
• Answer length: fewer words in means fewer input tokens, but how long the answer runs is still up to the model
• Privacy: it reads only what you paste, never the page you have open
