Build your own free Ai assistant in Gemini.

Most people use Ai like a search box. Ask, read, close the tab, then type the same background in again tomorrow. The people who get real value out of it do one thing differently. They set it up once, then reuse it. Three things: a free helper you build yourself, a prompt for chasing money, and a warning you can ignore.

One thing worth your time

A helper that already knows your business

Gemini’s free plan includes Gems: custom versions of Gemini you set up once. Write the instructions in plain English (what you do, who you serve, how you like to sound), add a file or two, save it. Every chat with that Gem starts from there, so you stop pasting in the same background. Free with a Google account, built on a computer at gemini.google.com. Google upgraded the free model on 21 July, so it runs on the newer one.

One prompt to try

Chase a late invoice without the awkwardness

Chasing money is the job owners put off longest, usually because the wording feels awkward. Give the Ai the facts and let it hold the tone for you. Fill in the brackets, read it once, send.

Write a polite chaser for an unpaid invoice.
Invoice [number] for [amount], sent [date], due [date], now [X] days late.
The customer is [name] and we have worked with them for [how long].
Tone: friendly, direct, no apology and no threat. Ask for a payment date.
Keep it under 120 words, then give me a shorter version for next week.

Save it as a Gem and it is ready every time.

One thing to ignore

The warning that Google punishes Ai writing

You have been told that if Ai writes your website, Google will bury it. Google’s own guidance says the opposite: “Appropriate use of AI or automation is not against our guidelines.” What it acts on is content mass-produced to game rankings, which was always the problem, whoever typed it. So draft with Ai, then do the part that counts: make it specific, accurate and worth reading.

That is it for this week: build the helper once, let it write the awkward email, and stop worrying about a search penalty that is not there.
