What you’ll build: an “Enquiry Reply Helper”. It’s a small AI assistant that knows your business (your prices, opening hours, area and tone of voice) and drafts a reply to any customer enquiry in seconds. You read it, tweak it and send it yourself.
What it costs: £0. You’ll use the free version of Google Gemini and a feature called Skills.
What you need: a computer, a free Google account, and you must be 18 or over. No coding, no card details.
Before you start: is this really an “agent”?
Let’s be honest from the start. People use the word “agent” for a lot of things. At the fancy end, an agent goes off and does jobs on its own: browsing websites, sending emails, updating spreadsheets. At the simple end, it’s an AI you’ve given a job description, some knowledge and some rules, so it does one task the same way every time.
This guide builds the simple kind, on purpose. It’s the safest way to start because nothing gets sent without you seeing it first. You’ll learn the core skill behind every agent (writing clear instructions) without the risk of an AI emailing your customers something wrong.
Why we picked Google Gemini Skills
We looked at the main free options in October 2026:
- Gemini Skills (Google) let you save reusable instructions that you can use in any Gemini chat. Google’s help centre says Skills are “available without a Google AI subscription”. That means they’re free for anyone 18 or over with a personal Google account.
- Zapier has a free plan, but the free plan only lets you preview its AI steps. You have to upgrade before an AI automation can actually run. Its separate “Agents” product is also being merged into the main Zapier editor right now.
- Gumloop, which we review, doesn’t show a permanent free plan on its pricing page. Manus, which we also review, does have a free plan: it costs $0 and gives you 300 credits a day. You’ll find it in Manus’s help centre rather than on its pricing page.
So Gemini Skills came out as the most genuinely free and beginner-friendly choice today.
Heads-up: Google is changing things this autumn. Skills are replacing an older feature called Gems. For personal accounts, Gems become read-only on 17 November 2026 and are removed on 17 December 2026. Google says it will move existing Gems into Skills automatically. If you don’t see Skills yet, see “If you can’t find Skills”.
10 minutesWrite down your business facts
This is the most important step. The AI only knows what you tell it, so a good fact sheet means good replies. Open a blank document or note and fill in this template. Keep it short and factual.
An example for a dog-walking business:
Don’t include: passwords, bank details, customers’ names or addresses, or anything you’d mind a stranger reading. (We explain why in Step 2.)
3 minutesOpen Gemini and check one setting
- On your computer, go to gemini.google.com and sign in with your Google account.
- To use Skills, Google says the Keep activity setting must be on. You’ll find it under Gemini Apps activity in the settings.
What “Keep activity” means for your privacy. Google’s Gemini privacy notice (updated 13 October 2026) says that with this setting on, your chats are saved to your account and can be used to improve Google’s AI. That includes having some chats read by human reviewers. Reviewed chats are kept for up to three years, even if you delete them. Google’s own advice is: don’t enter anything confidential that you wouldn’t want a reviewer to see.
- Your business fact sheet is fine, because it’s information you’d put on your website anyway.
- When you paste in a customer’s message, remove their name, phone number, email address and home address first. You don’t need them for a draft reply, and leaving them out keeps your customers’ data out of Google’s systems. That matters under UK data protection law too.
7 minutesCreate your skill
- In Gemini, open the sidebar on the left and click Customize. (If you can’t see it, click More first.)
- At the top, click Skills.
- Click Create. Google offers a few ways to make a skill: with help from Gemini, from a ready-made template, from a blank template, or by uploading a file. Choose the blank template (on some screens this is called Create manually).
- Fill in the boxes as shown below.
- Click Create (or Save) at the top.
- Name
enquiry-reply-helper
Skill names use lower-case words joined by hyphens. Gemini may tidy the name for you.- Description
- Drafts friendly replies to customer enquiries for my business, using my business facts.
- Instructions
- Copy the text below, then paste your fact sheet from Step 1 where it says to.
That’s your agent. It now lives in your Skills page and you can use it in any chat.
7 minutesTest it with made-up enquiries
Before you use it with real customers, try three made-up messages. Start a new chat, type / (Google says this is changing to @), pick enquiry-reply-helper, and paste a test message. Change these to suit your business:
- An easy one: “Hi, how much is a solo walk and do you cover LS10?”
- One it shouldn’t know: “Do you have any availability on the 14th?”
- One you don’t do: “Can you look after my dog this weekend?”
Check each reply against this list:
- Are the prices and facts correct?
- For question 2, did it write [CHECK: ...] rather than making up an answer?
- For question 3, did it politely say no, and offer an alternative?
- Does it sound like you?
- Is it short enough to read on a phone?
If something’s off, go back to Customize > Skills, open your skill and edit the instructions. The most common fix is adding a fact you forgot, or a rule like “Never offer discounts”.
3 minutes, then every dayUse it for real
When an enquiry comes in by email, text, Facebook or wherever:
- Copy the customer’s message, leaving out their name and contact details.
- In Gemini, type / (or @), choose your skill and paste the message.
- Read the draft. Fill in any [CHECK: ...] gaps. Tweak anything that doesn’t sound right.
- Copy it into your own email or messaging app, add the customer’s name and send it yourself.
Gemini can also apply a skill automatically when it thinks it’s relevant, but choosing it yourself is more reliable while you’re learning.
What it costs
| Item | Cost |
|---|---|
| Google account | £0 |
| Gemini (free, no Google AI plan) | £0 |
| Skills | £0 (Google: “available without a Google AI subscription”) |
| Total | £0 |
The catch with “free”: Google’s free plan has “standard” usage limits. They’re based on how much computing each request uses, refresh every five hours and have a weekly cap. Google doesn’t publish an exact number of messages. Drafting short replies is a light job, so most small businesses are unlikely to hit the limit, but we haven’t tested that. Since 9 October 2026, free accounts can’t choose which AI model they use. Gemini’s “Auto” setting picks for you, and reports say most free requests go to its smallest, fastest model. That’s fine for short replies, but it may be less sharp on tricky questions.
Paid Google AI plans raise the limits. You don’t need one for this guide.
What can go wrong (and what to do)
- It makes something up. All AI tools sometimes state things confidently that aren’t true, a problem known as “hallucinating”. The rules in your instructions reduce this, but they don’t remove it. Always read every reply before sending, especially prices and dates.
- You can’t find Skills. Check that you’re signed in to a personal Google account (work and school accounts get Skills later), that you’re 18 or over, and that Keep activity is on. Google is rolling Skills out in stages, so it may not have reached your account yet. See below.
- You hit a usage limit. Wait for it to refresh (Google says limits refresh every five hours), or write the reply yourself that day.
- Replies sound robotic. Paste two or three real replies you’ve written before (with names removed) into your instructions under “Examples of how I write”.
- Google changes the feature. Google is retiring Gems and moving to Skills right now, so menus and names may move. The idea stays the same: saved instructions plus your facts.
- Privacy slips. If you paste in a customer’s personal details by mistake, you can delete that chat in Gemini Apps activity. But Google says chats that have already been reviewed are kept for up to three years, so prevention is better than cure.
If you can’t find Skills
Until 17 November 2026, you can build the same helper as a Gem:
- At gemini.google.com, open the sidebar and click Gems, then New Gem.
- Enter a name, paste the same instructions and click Save.
Google says Gems will be moved into Skills automatically when they’re retired. After 17 November 2026, existing Gems become read-only, so use Skills if you can.

AI tools change fast, so if something here is out of date, tell us via @newtoagents or [email protected] and we’ll fix it.
New to Agents has no affiliate deal with Google and earns nothing if you use Gemini.
