A prompt builder is only worth using if it produces something you would not have written yourself. These prompts do three things most hand-written ones miss: they set a length, they forbid invention, and they leave visible placeholders where you have not supplied a detail.
Pick the job, fill in the blanks, copy the prompt into whichever assistant you already pay for. Everything runs in your browser.
How to use it
- Pick the job. Seven of the messages small businesses rewrite every week: chasing money, answering a price objection, asking for a review, following up a quiet quote, handling a late cancellation, collecting details before a job, replying to a complaint.
- Fill the details you actually know. Leave the rest blank and the prompt keeps a placeholder, which is the point.
- Copy and paste. The prompt goes into ChatGPT, Claude, Gemini, whichever you use.
- Edit the draft. Not optional. The model writes a first version; you own what gets sent.
Why a structured prompt beats a clever one
“Write a polite email chasing an invoice” produces something generic, because the model fills every gap with guesswork: a made-up name, a date it invented, a threat you did not want. Each prompt here closes those gaps instead. Length is specified, the ask is specified, and anything you left blank is marked in square brackets so you can see exactly what you still need to decide.
The seven jobs
Each one is a message you already send several times a month, and each has a failure mode the prompt is written to avoid: chasing that sounds either desperate or aggressive, a price objection answered with discounting, a review request that sounds like a favour, a follow-up that reads as nagging.
If you want the same prompts stored as a reference rather than generated, the library of prompts for small business owners has them written out, and customer replies that do not sound like a robot covers the tone question in more depth.
Editing before you hit send
Read the draft out loud. If a sentence is not something you would say to that customer’s face, cut it. Check every date, amount and name, because a model will occasionally move a fact one line further than you intended. Then cut about a fifth of it, since first drafts are almost always too long.
What not to paste
Do not put customer card details, addresses, medical information or anything you would not read out in a crowded room into a public AI tool. First names and job descriptions are usually enough for these messages. If your customer data is sensitive, keep the prompt generic and add the specifics yourself afterwards.
The pricing behind those messages is a separate job: the free hourly rate calculator works out your floor, and the quote and estimate builder turns it into a document you can send.
Questions
Do I need a paid AI account?
No. These prompts work with free tiers of the major assistants. Paid tiers mainly get you longer context and newer models, neither of which matters much for a 120-word email.
Will the messages sound like a robot?
They will if you send the first draft unedited. The prompt sets the tone and forbids invented detail, which removes most of the tells, but your own phrasing is what makes it read like you. Swap one sentence per message for something you would actually say.
Can I use these for SMS or WhatsApp?
Yes, but change the length rule in the prompt: 120 words is an email, not a text. Editing the copied prompt is expected; it is a starting point, not a fixed script.
Is anything I type stored?
No. The tool runs in your browser, nothing is submitted to our server, and closing the tab clears it.
