The product

The AI Business OS — for anyone who works for themselves.

We call it an OS because it covers every department of a one-person business, not one task.

30 tasks across sales, delivery, content, admin and rhythm, each built so what you get back reads closer to expert work than a generic AI draft, in that department. Paste, fill the brackets, send — delivered as an 83-page PDF and a Claude Projects pack (a zip of markdown and CSV files). Works in ChatGPT or Claude, free version included.

Need it set up for you? The Implementation Edition ($97) sets it up for you — automations and step-by-step walkthroughs included.

Objections, answered

The five things people ask before buying.

I already use ChatGPT for this.

Then you already know the blank-page problem — you're still writing the prompt from scratch every time. The OS replaces the blank page with the prompt, the template, and a worked example, so you paste and go — no prompt-writing skill required, and the output is a solid first draft you can send after a quick edit.

Isn't this just prompts?

A prompt on its own is one line. Each of the 30 tasks is a prompt, the template the output fills, and a worked example — built for a specific job in your own business, not general writing.

Will the output sound like me?

Every task has a short "make it yours" step for tailoring tone and detail to how you actually work. The prompt is a starting point you edit, not a script you publish as-is.

How long does this take to set up?

There's nothing to install or configure. Buy, open the PDF, and drop the first prompt into ChatGPT or Claude. In our own runs, the first task was running inside ten minutes.

What happens right after I pay?

You get instant access — a confirmation page, then an email with your download link and a short first-win guide. Nothing to wait on, nothing to configure.

30-day try-it guarantee. Run one task first. If it doesn't earn its place in your week, write to support@sundayclear.com within 30 days of purchase with one completed task — a screenshot or a paste of what a prompt gave you back is enough — and we refund you in full.

Questions about the OS.

Do I need to know anything about AI?

No. If you can copy and paste, you can use every task. Each one tells you exactly what to fill in, and the wording is already done for you.

What exactly do I get for $27?

30 tasks, six in each of five departments (sales, delivery, content, admin, rhythm). Every task is a written prompt, the template it fills, a worked example, and a one-minute walkthrough script. Delivered as an 83-page PDF plus a Claude Projects pack (a zip of markdown and CSV files) you can load into Claude in one go. Access is instant on the thank-you page, plus an email link that works for 30 days.

Does it work with ChatGPT, or only Claude?

Yes — every task is written for ChatGPT and tested to also work in Claude, free version included. You paste the same text into either tool — nothing to install, no new software to learn.

I don't run a "business", I just do work on the side. Is it for me?

Yes. The tasks are the everyday ones: quotes, client emails, invoices, a weekly plan. They fit a side project as well as a full-time one.
