In the first week, use one free general assistant (ChatGPT, Claude or Gemini) for one small task a day: set rules on Monday, then draft replies, tidy a spreadsheet, write one customer document, summarise notes, make one post and review on the last day. Log minutes saved. Keep what worked, drop the rest, and paste nothing sensitive.
The order is deliberate. Day one sets the safety rules, because it is easier to build the habit before you have a pile of material. Days two to six each use a different everyday job, so you find out where AI fits your business and where it does not. Day seven is a review, and it matters most, since a week of experiments with no decision at the end changes nothing.
What free means, and the limits to know about
Free plans change often, and the numbers are frequently not published. The facts below were checked on each vendor's own pages in November 2026; read each pricing page again on the day you start, because a free allowance may differ by then.
| Tool | Free tier | Limits and data points to know |
|---|---|---|
| ChatGPT | Free at $0: unlimited text chats, with limited uploads, image creation, voice, deep research and memory | OpenAI's help centre says ads may appear on the Free and Go plans; an ad-free Free option comes with lower limits. The privacy table lists an opt-out from model training on Free; check it in data controls. |
| Claude | Free at $0: chat, web search, file creation, memory across conversations and up to five Projects | The pricing page describes "limited usage" every five hours and every week without giving numbers, and Sonnet and Haiku models rather than Opus. Model training on the Free plan is listed as opt-out. |
| Gemini | Free with a Google account | With Keep Activity on, Google may use chats to improve its services, and some are read by human reviewers. With it off, Google says future chats are not used to train its models but are still kept for 72 hours. |
| Canva | Free plan with limited AI | The pricing page lists "limited access" to Standard and Premium AI tools on Free and gives no number of uses; Pro is described as 10x Free's AI allowance. |
| Zapier | Free plan | 100 tasks a month, two-step automations only, checks every 15 minutes. |
| Mailchimp | Free plan | 250 contacts, 500 sends a month (250 a day), and no marketing automation flows. |
Two points deserve more than a table row. First, usage limits on free plans are usually per time window, so a heavy day can lock you out for hours. Plan the week's tasks to be short rather than long. Second, free consumer plans are the least protected on data. OpenAI, Anthropic and Google all say their business plans do not train on your organisation's content by default, while their consumer plans may let your chats improve models unless you switch that off. Until you have checked the setting, assume anything you type could be seen again.
Day one: choose one tool and write your three rules
Pick a single assistant. If your email and documents live in a Google account, Gemini is already signed in. If you want a chat with projects and good writing, try Claude or ChatGPT. It does not matter much which; it matters that you stay with one for seven days.
Open its settings, find the privacy or data controls, and decide whether your chats may be used for training. Turn it off if you can. Then write three rules on a card and stick it by your screen.
- Never paste passwords, card or bank details, full customer addresses, health information, contracts you have signed or anything under a confidentiality promise.
- Use placeholders for names, such as [customer], and for amounts you do not want to share.
- Read everything that goes out in your name, and check numbers, dates and promises against your own records.
Spend the rest of the day on a ten-minute test: ask the tool to explain what your business does, using a paragraph you give it. See how it reads you. Correct it, and save the corrected paragraph in a note, since you will paste it in as background on later days. The privacy terms checklist shows what to look for in the small print when you have an hour.

Buy nowHow a four-person roofing company ran the week
The roofing company here is an illustration, and its minutes are invented. It has four staff, one of them running the office, and the owner tries the plan. The owner logs minutes before and after each task. Here is how the week goes, with the results in a table at the end of the section.
Day two: draft replies to the enquiries you already have
Take five real enquiry emails from your inbox. Remove names and addresses. Paste one at a time with this prompt.
I run a small roofing company. Here is a customer enquiry (details removed).
Write a reply of under 120 words that thanks them, asks the two questions we need
before we can quote (roof type and approximate size), and suggests a site visit
this week. Tone: friendly, plain, no hype. Do not promise a price or a date.
Enquiry: [paste]An illustrative result opens "Thanks for getting in touch about the leak above the back bedroom" and ends with a question about roof type and a proposed visit. What the owner fixes: it invented "we can usually come within 48 hours", which the owner cannot promise, so that line goes. After the fix, the draft takes two minutes against about six minutes of writing from scratch. Over five emails, the owner saves about twenty minutes, and notes that two of the five replies still needed a phone call.
Day three: tidy one spreadsheet
Pick a sheet you already have, such as last year's jobs with date, type, value and source of lead. Copy 30 rows into the chat with the amounts and names changed if need be, and ask for something small: "List the three most common job types by count and by total value, and show the arithmetic." Check the answer against a quick pivot table or a calculator. The aim is not a clever analysis. It is learning to catch the model when it adds wrongly. If you use Google Sheets, the Sheets AI prompts tutorial shows ways to bring the same help inside the sheet.
Day four: write one customer-facing document
Choose something you rewrite often, such as the "what happens when you book a roof inspection" page, a quote cover note or a warranty explainer. Give the model your own bullet points and ask it to write them as a clear page of 250 words in plain English. An illustrative output opens with "Here is what to expect, step by step", and the owner removes a sentence calling the firm "the most trusted roofers around", which is a claim nobody can prove. Anything that claims, guarantees or states a price needs your approval.
Day five: turn rough notes into a checklist or summary
After a job, type or dictate five lines of notes on your phone and ask for a one-page job summary or a checklist for the next crew. Or take the notes from a team meeting and ask for decisions, actions and owners as a table. This is where many owners feel the first real saving, because the task is dull and the input is already there.
Day six: one post, one small automation
Ask the assistant for three short social posts from a finished job, using details you supply, and make one image in Canva's free plan. If you want to try a tiny automation, use Zapier's free plan for a two-step job, such as saving a form enquiry to a sheet. Keep it small, since the free plan allows 100 tasks a month and two steps per automation. Skip the automation if it feels like a second job.
Day seven: review and decide
Open your log. For each of the six tasks write down minutes before, minutes after, and whether you would do it again. Illustrative figures for the roofing example:
| Task | Before (min) | After (min) | Keep? |
|---|---|---|---|
| Five enquiry replies | 30 | 10 | Yes, weekly |
| Spreadsheet summary | 25 | 20 | Not yet; error-prone |
| Inspection page | 60 | 25 | Yes, for documents |
| Job summary from notes | 15 | 5 | Yes, daily |
| Three social posts | 40 | 20 | Yes, once a week |
| Zapier enquiry log | 45 to set up | 0 after | Maybe; wait for week two |
Leaving out the one-off Zapier set-up, the total before is 170 minutes and the total after 80, a saving of 90 minutes, and more than half of it came from two tasks: the inspection page and the enquiry replies. The owner decides to keep three habits and drop one, and writes down one lesson: the spreadsheet task needs a check on every number, so it stays manual for now. That decision, not the 90 minutes, is the result of the week.
A background note that makes every day faster
Claude's and ChatGPT's free plans both list a memory feature, but what it keeps is not under your control line by line, and you may prefer it off for business work. The dependable fix is a background note you paste at the start of a chat. Write it on day one, keep it under 150 words, and include only what is safe to share: what the business does, who the customers are, your tone and what you never promise.
Background: We are a four-person roofing company doing repairs and replacements for
homeowners. Customers are usually anxious about leaks and cost. Our tone is calm,
plain and practical. We never quote a price or a date without a site visit.
We never use phrases like "best in class" or "unbeatable". Write in British English.With that note, replies on day two need fewer fixes, because the model starts from your rules instead of its defaults. Both Claude's Free plan (up to five Projects) and ChatGPT's Free plan list a Projects feature, so you can store the note there instead of pasting it. Keep it free of customer details either way.
A second sample: notes into a job summary
On day five the owner dictates these notes after a repair: "Tuesday, flat roof over rear extension, patched two splits near the drain, resealed edge, took photos before and after, customer wants a quote for replacing the whole roof next spring, left a card." The prompt asks for a one-page summary with sections for work done, observations and follow-up. An illustrative output:
Job summary: Rear extension flat roof, Tuesday
Work done: Patched two splits near the drain outlet. Resealed the edge.
Observations: Splits were close to the drain. Photos taken before and after.
Follow-up: Customer would like a quote to replace the whole roof next spring.
Action: Diary a reminder to contact the customer in [month].What the owner fixes: the model wrote "Splits were likely caused by pooling water", which nobody said. The owner deletes it. This is the usual pattern with summaries. The structure is helpful and a single invented explanation is the thing to hunt for. A quick pass reading each sentence and asking "did I say that?" takes thirty seconds and catches most of it.
Time budget: the week on a diary
Plan on 20 to 40 minutes a day. Day one is the longest, because of settings and rules, at up to an hour. Put each day's task in your calendar at a time when you would otherwise be doing it anyway, such as straight after you open the inbox for day two. Tasks tied to real work get done, and tasks tied to a good intention do not.
Swap the example to fit your business
The plan works for any small business, since each day is a type of task, not a trade. Three quick variations show how the same days change.
A pest-control firm
Day two is replies to booking enquiries and day five turns technician notes into a visit report for the customer. Day four becomes a plain-language page on what a treatment involves and how long to keep pets out of an area, written from your own procedure and checked against it.
A cleaning company
Day three is a rota or a price-by-room sheet, and day five becomes a checklist for each type of clean. Day four is the "what's included" page. The risk to watch is invented inclusions: make the model use your list and nothing else.
A plumbing firm
Day two is quote follow-ups, and day five is job notes into invoice lines. The invoice step needs the same rule as the spreadsheet day: every quantity and price is checked against the job sheet, because a model reading hurried notes can misread a quantity as easily as a tired person can, and an invoice line is where that costs money.
If you only have ten minutes a day
Some weeks are chaotic. Shrink each day to its smallest useful version: day two becomes one reply instead of five, day three becomes ten spreadsheet rows, day four becomes a single paragraph of the page, and day five becomes one set of notes. You still learn how the tool behaves and still log the result. A thin week with an honest review is worth more than an ambitious one abandoned on Wednesday.
A good test of a first week is whether you can finish this sentence on day seven: "Next week I will use AI for ___, with this prompt, and I will check ___ every time." If you can fill both blanks, the week worked, whatever the minutes say.
How to judge a day without fooling yourself
People overrate AI when they time only the drafting and forget the checking. Use this simple rule: count the minutes from opening the chat to sending the finished work, including every correction. Compare that with how long the task usually takes you, using a rough guess you wrote down before you started, because memory flatters.
Score the quality too. Give each output a mark of one to five: one means unusable, five means you would send it as it is. If the average is under three after the fixes you made, the task is not a fit yet. If you can reach four with a better prompt, save the prompt in a notes file. By the end of the week, you should have a small folder of three or four prompts that work, and that folder is worth more than any list of tools.
What goes wrong in week one
- Confident wrong numbers. The model produces totals that look right and are not. Always check arithmetic on a calculator for the first few tasks.
- Invented promises. Drafts offer discounts, deadlines or guarantees you never mentioned. Read for verbs like "will" and "guarantee".
- Sensitive data pasted by habit. A customer's full address slips into a chat on day four. Keep the card by your screen and use placeholders.
- Tool-hopping. Trying five assistants in a week shows nothing about your business. Compare tools in week two, with the same tasks.
- Doing too much. One task a day is the plan. A heroic Wednesday followed by a skipped Thursday is common and does not matter, as long as day seven still happens.
Staff, customers and what to tell them
If anyone else will use these tools, give them the three rules and the list of things never to paste. The shadow AI tutorial explains why leaving it unspoken is risky. Tell staff what you are using AI for, so they do not start using their own tools in ways you have not seen. For customers, the standard is simple: you stay responsible for anything sent in your name, so check it, and follow any disclosure rule in your sector.
Keep a one-page note of what you used, which plan, and what you decided on privacy settings. If you later add paid tiers, that note shows you what changed. Record any worries too, with the date and what you decided, so the next review starts from a list rather than from memory.
After week one: what to do with the result
You now have three things you did not have seven days ago: a log of minutes saved or not saved, a short list of working prompts and a feel for where the tool lets you down. Use them to choose week two, which should take the best task from week one and make it routine. If drafting replies saved most time, set up a saved set of instructions in a Project or similar feature, and repeat it daily. If summarising notes won, find the point in your day where the notes arrive and add the step there.
Only now should you look at money. Count the weekly minutes saved, multiply by what your time is worth, and compare with the cost of a paid plan. Where you keep hitting the free limits or need stronger data protection, the free versus paid tutorial helps with the choice, and the list of free tools and their catches covers the next tools to try. If you would rather map your own business with someone, that is what my AI implementation consultation covers; you can reach me through the contact page.
Questions owners ask before starting
Which free AI tool should I start with?
Pick one general chat assistant, such as ChatGPT, Claude or Gemini, and use only that for the week. Switching tools hides whether the work is improving. Choose the one that fits tools you already use, such as a Google or Microsoft account, then compare a second tool in week two.
Is it safe to put customer details into a free tool?
Treat free consumer plans as places for non-sensitive text. Use placeholders for names, addresses, phone numbers and prices you do not want shared. Check the data settings in each tool, because consumer plans may use chats for training unless you switch that off, while business plans usually do not by default.
What if I hit a free usage limit mid-week?
Claude's Free plan limits usage every five hours and every week without publishing numbers, and ChatGPT's Free plan lists unlimited text chats but limited uploads, images and research. If you run out, finish the day's task by hand or the next morning, and note it. Hitting a limit twice in one week is useful evidence about whether a paid plan would earn its cost.
Do I need to tell staff and customers I use AI?
Tell staff what you are using it for and what they must never paste into it. For customers, you are responsible for what you send in your name, so check everything, and follow any disclosure rule that applies to your sector. Ask an adviser if a regulation applies to you.
When should I stop using free tools and pay?
When a task you do weekly takes less time with a paid feature, when the free limits stop you working, or when you need business-plan data protection for customer information. Count the minutes saved first, and see the plan comparison tutorials for what each tier adds.
