Use one AI assistant for the writing and reading that fills your week: client replies, proposals, call notes, research and admin. Give it a one-page brief about your business once, so you do not repeat yourself. Review everything it writes before it goes out, and keep outreach one to one.
The short answer
When you have no staff, every hour of admin comes out of client work or your evenings. AI gives you a first draft of most things you write, and a summary of most things you read. That is where the hours go.
You need one paid plan. As of October 2026, in US dollars:
- ChatGPT Plus is $20 a month (OpenAI).
- Claude Pro is $20 a month, or $17 a month billed yearly (Claude pricing).
- Gemini in Gmail comes with Google Workspace Business Starter at $7 per user a month on a yearly plan (Workspace pricing).
On a personal plan, turn off model training first. In ChatGPT it is Improve the model for everyone under Data controls (OpenAI). In Claude it is Help Improve our AI models under Privacy (Anthropic).
Set up once: your business brief
What I sell: [service, price range, who it is for].
My clients: [type, size, what they care about].
How I work: [process from first call to delivery, in five lines].
How I write: short sentences, plain words, [your sign-off]. Never: [phrases you hate].
Rules: never promise dates, prices or results I did not give you. If unsure, ask me.

Practical uses, with prompts
1. Client replies
Here is an email from a client: [paste]. Draft a reply in my voice. Answer every question they asked, in order. Under 120 words. End with one clear next step. If the email asks for something outside my scope, say so politely and offer the closest thing I do.
2. Proposals
From my notes of the call with [client], write a one-page proposal: their problem in their words, what I will do, what is not included, timeline, price [price], and the next step. Use only facts from my notes. Mark anything you had to assume.

3. Calls and meetings
Here is the transcript of my call with [client]. Give me: what they want, what I promised, open questions, and a short follow-up email in my voice that confirms the next step and the date.
A note taker writes the transcript for you. Fathom has a free plan with unlimited recordings (Fathom pricing). Tell clients you record.
4. Research
I am preparing for a call with [company]. From their website and any public news, list what they sell, who they sell to, and anything that changed in the last year. Give the source link for every point. Say clearly if you could not find something.
Open the links before you use a fact. AI can mix up companies with similar names.
5. Admin
Write a polite reminder for invoice [number], [amount], due [date], now [days] days late. Two short paragraphs. Friendly, firm, no apology. Include how to pay: [method].
There are ready versions in overdue invoice reminder emails. AI can also tidy a list of expenses you paste in. Check anything tax related with your accountant, because rules differ by country and state.
6. Marketing you can do alone
A client asked me: [question]. Write a short LinkedIn post that answers it in plain words, from my experience. Under 150 words. No hashtags in the text. End with a question to readers.

Outreach: one to one, never bulk
AI makes it easy to write a hundred emails. Do not send them. Write to people you chose, one at a time, about something specific to them.
- Pick each person yourself. Never buy, rent or scrape a contact list.
- Write each email for that person: why them, why now, one easy question.
- Send from your own inbox, one at a time, after you read it.
- In the US, follow CAN-SPAM. It covers business to business email too, with penalties of up to $53,088 per email.
- In the UK, PECR allows marketing email to company addresses, but sole traders are treated as individuals and need consent.
- Stop at the first no, and keep a list of people who asked not to hear from you.

What not to hand to AI
- Your prices and promises. AI drafts, you decide.
- Replies to complaints or upset clients. Write those yourself.
- Anything you would sign, and anything under a confidentiality agreement.
- Passwords, bank details and personal data you do not need to share.

Nive is being built for this problem: you write how your business works and how you sound once, and it drafts emails in your voice for you to review and send. It never sends email, never finds or buys contacts, and never sends in bulk. Join the waitlist to get the demo first.
