Five playbooks for your ChatGPT Project

playbooks/

A playbook is a plain text file you add to your Project once. Then you say its trigger phrase and ChatGPT follows your steps:

quick-reply-library
Builds a set of saved replies for WhatsApp, Instagram, Facebook, and email, in your tone, from your profile.
appointment-reminder-writer
Writes confirmations, reminders, reschedule, no-show, and late-cancel messages from your bookings list.
house-policy-writer
Drafts your cancellation, deposit, refund, and payment policies, a short customer version, and polite replies for when a policy is broken. Not legal advice.
staff-rota-builder
Builds next week's rota from availability and busy times, flags gaps, and drafts the team message.
sop-checklist-writer
Turns your voice memo or notes into a step-by-step checklist for staff.

10-minute daily admin routine

05-daily-admin-routine.md

A short routine for each working day, a 30-minute weekly routine, and 30 ready-to-use prompts, so the setup becomes a habit instead of something you tried once. Everything works from text you paste in.

Your first 5 jobs, by type of business

  • Prompt 14quote from notes“Turn my notes into a quote using my prices. List every assumption you made. Notes: [paste]”The quote is usually the slowest document you write, and it is the one the client is waiting for.
  • Prompt 15follow up a quote“I sent [customer] a quote for [job] on [date] and heard nothing. Draft a short, no-pressure follow-up in my tone.”Quotes go quiet. A short nudge is the job most owners never get to.
  • Prompt 10overdue invoices“Here is my list of unpaid invoices: [paste]. List the overdue ones oldest first and draft a reminder for each.”Getting paid for finished work comes before finding new work.
  • quick-reply-libraryplaybook“Use the quick reply playbook. Build my quick replies for email and WhatsApp.”The same questions arrive every week. Answer each one once, in your voice.
  • Prompt 4long email to answer“Summarize this email in 3 lines: what they want, by when, and what I need to decide. Then draft a short reply: [paste]”Client emails are long. Start from what they want and by when.

From the first jobs map in the kit. Every job is one of the kit's 5 playbooks or 30 prompts, and every one of them works on a free ChatGPT account from text you paste in. Prompt numbers match the kit.

Free ChatGPT

The whole core kit: your first win, your business profile, a business Project with your profile and house rules, the 5 playbooks and the 30 prompts. A free Project holds 5 files, so the kit includes one merged playbook file. Free allows 3 file uploads a day and limited usage, so a long session may pause.

Paid ChatGPT (Go, Plus or Pro)

The same kit with more room: 25 files per Project on Go and Plus, 40 on Pro. See chatgpt.com/pricing for today's plans and prices.

Per OpenAI's help pages, October 2026. OpenAI's pages disagree about which plans include Skills and scheduled tasks. This kit depends on neither.

Fit check

Made for you if

Owners and small teams who handle their own customer messages and admin, in any of these kinds of business:

  • Service businesses
  • Shops
  • Clinics
  • Salons
  • Trades
  • Restaurants

You do not need a technical background. If you can fill in a form and copy and paste, you can do this. It is a do-it-yourself kit, not a done-for-you service, and it stops at a draft on purpose: nothing is sent without you.

Questions

Straight answers before you buy

Do I need a paid ChatGPT plan?

No. The core kit works on Free, per OpenAI's help pages, October 2026. Free has tighter limits: 5 files in a Project, 3 file uploads a day, and limited usage, so a long session may pause. Paid plans give you more room. Plans change, so check chatgpt.com/pricing.

How long does setup take?

The plan adds up to 3 hours 10 minutes, with a break in the middle. These are planning estimates. Your first win, 3 draft replies in your voice, takes about 15 minutes.

Will ChatGPT send messages to my customers?

Not with this kit. Every prompt and playbook ends with a draft. You read it and send it yourself.

What is a playbook?

A plain text file that tells ChatGPT how to do one job your way: what it needs from you, the steps, the output format, and the draft-only rule. You add it to your Project once, then start it with a short phrase.

Will ChatGPT get everything right?

No AI tool does. The kit is built around ChatGPT drafting and you reviewing before anything is sent. It is not legal, medical, financial or tax advice.

Is this an official OpenAI product? What about the other Business Brain Kit?

No. Davejo is independent and not affiliated with OpenAI. ChatGPT is a trademark of OpenAI. This edition is written for ChatGPT and sold separately from the other Business Brain Kit. One purchase covers one business; see our Terms of Service.

What if it is not right for me?

The Real Work Guarantee: try it for 14 days. If it does not save you real work, ask for a full refund, no questions asked. See our Refund Policy, or email [email protected]. We reply within 3 business days.
