New shop, honest about it. Hustle Studio is a small new shop, so this kit has no reviews yet and we won't invent any. Instead, the images below show the real Builder (with fictional example data) and real pages from the guide PDF, and the free sample further down is copied word for word from prompt-library.txt. We reply to support email within 2 business days, and fixed or improved files go on the same download page at no cost.

Rendered straight from ai-prompt-kit-guide-letter.pdf. Click any page to open it full size.
Copied unchanged from prompt-library.txt. Replace {{profile}} with a few lines about your business and fill in the [brackets], or let the Builder do both for you.
P4-01 | Reply to 'can you do it cheaper?'
When to use: The client likes the proposal but asks for a lower price.
About me: {{profile}} [Client name] asked for a lower price on [Project], quoted at [Price]. Write a reply that keeps the price and offers a smaller scope at [Lower option price] instead. Under 100 words. Do not offer discounts or extra work unless I say so.
Check 1: The price holds · Check 2: Less scope, not a discount · Check 3: Under 100 words
P5-01 | 'Can you just add one more page?'
When to use: The client asks for something small that isn't in the scope.
About me: {{profile}} [Client name] asked me to add [New request] to [Project]; it is outside the agreed scope. Write a reply that welcomes it as a change request at [Change price] and [Extra days] extra days. Under 100 words. Do not offer discounts or extra work unless I say so.
Check 1: Called a change request · Check 2: Price and days stated · Check 3: No 'happy to throw it in'
P6-03 | First reminder: invoice 14+ days late
When to use: The due date has passed and your nudge got no reply.
About me: {{profile}} Write a payment reminder to [Client name] at [Company]. Invoice [Invoice #] for [Amount] was due [Due date] and is [Days overdue] days overdue. Ask them to pay this week via [Payment link]; late payment is handled under the terms in our agreement. Under 120 words, one clear ask, no apology. Do not offer discounts or extra work unless I say so.
Check 1: Amount and dates match · Check 2: No 'sorry to bother you' · Check 3: One date, one way to pay
Most prompt packs give you a long list and leave the rest to you: paste a prompt, swap every [BRACKET], explain again who you are and what you charge, then hope the AI doesn't offer a discount or promise free extra work.
This kit takes a different approach. It has 120 prompts, all for the conversations where money and scope are at stake: cold pitches, discovery calls, 3-tier quotes, "can you do it cheaper?", "can you just add one more page?", deposits, reminders and late invoices, retainers and renewals.
How it works. Open prompt-builder.html in your browser. Fill in My Business once: your name, what you do, who you serve, your services and prices, currency, typical project size, proof points, tone (Warm, Direct or Formal) and sign-off. Pick a prompt, fill in the situation (for example: client Dana Price, invoice #1042, $1,800, due Sept 30, 14 days overdue) and press Copy prompt. Paste it into your own ChatGPT, Claude, Gemini or any chat AI. Any field you leave empty stays in [brackets] and shows in yellow, so you can see what's missing before you copy.
Every prompt is written to protect your price. Each one sets a word or sentence limit. Every prompt in Pricing, Scope Creep and Getting Paid tells the AI: Do not offer discounts or extra work unless I say so. Where it fits, prompts add terms like "late feedback moves the timeline; the payment due date does not change." Under each prompt you get 3 checks to run before you send.
The Builder also lets you search all 120 prompts, filter by category, star favourites, add your own prompts, and export or import your data as JSON. It runs offline, makes no network requests and stores your data only in your browser.
The guide (40 pages, US Letter and A4) explains how to write your profile block, the 5 mistakes AI makes in client emails and how the checks catch them, all 120 prompts as blank templates with their checks, the 24 Before / After examples, a 20-minute weekly AI admin routine, and a clickable index.
Honest limits. No AI is included: you paste the prompt into your own ChatGPT/Claude/Gemini account. AI drafts still need your review before you send them. The Before / After emails are examples we wrote to show the target, not live AI output, and the people and companies in them are fictional. This is not legal, tax or financial advice.
Do I need a paid ChatGPT account?
No. The prompts work in free and paid versions of ChatGPT, Claude, Gemini or any chat AI. The kit doesn't include an AI; you paste the prompt into the one you use.
Is my business information uploaded anywhere?
No. The Prompt Builder is a single HTML file that runs in your browser, makes no network requests and saves your data only in that browser. Export JSON gives you a backup file; Clear my data deletes it.
Does it work on a phone or iPad?
Yes. The Builder works in desktop browsers (Chrome, Safari, Edge, Firefox) and on phone-width screens, where it switches to a single column with a Copy button that stays at the bottom. Filling in long fields is easier on a computer.
Can I use the prompts in Notion or Google Sheets?
Yes. Import prompt-library.csv into Notion (Import, then CSV), Google Sheets or Excel. The TXT file has the same 120 prompts in plain text.
Will the AI write emails I can send without editing?
Treat them as strong first drafts. Each prompt has 3 checks to run before you send, and you should always read the draft and fix anything that isn't true for your situation.
