A four-part series on the questions people actually ask about ChatGPT. Written for people using it at work, in plain English, with the steps you can follow today rather than a list of features.
Most people type a request and take whatever comes back. The fix is a proper brief: role, task, audience, constraints and format. Plus the follow-ups that turn a bland first answer into something usable.
Read the guide → Part 2 of 4Writing, images, coding, long documents, voice, price and free tiers, compared honestly. Then a simple rule for which one to open first, based on the task rather than the brand.
Read the guide → Part 3 of 4Atlas puts ChatGPT inside a browser and Codex puts it inside your code. Here is what each one really does, where agent mode earns its keep, and what you should never let it touch.
Read the guide → Part 4 of 4Cancelling on the web is not the same as cancelling an App Store or Google Play subscription. Follow the right route for how you paid, then confirm it in three places so you are not charged again.

Get In TouchMachine learning is the method behind almost every AI tool you have heard of, and almost nobody has ever had it explained properly. This three-part series fixes that: what machine learning is, what a model is, and what an algorithm is – in plain English, for business owners and teams, with no maths and no coding.
A computer learning from examples instead of rules, explained in one sentence and then properly. Where it already works in your business, and why you need no maths.
Part 2 of 3The trained pattern a computer keeps and reuses. How models get built, the four types you actually meet, and why the data sets the ceiling.
Part 3 of 3Algorithm is the recipe, model is the cake. The four families you will actually hear about, and the questions worth asking about any of them.
The short version: how machine learning sits inside the wider field of AI, and why that one shift changed everything.
Prediction, patterns and training data, explained without a single equation.
The generative models that write, draw and code, and how they differ from the machine learning already in your tools.

PR already owns the hardest part of generative engine optimisation: earning credible third-party authority. So why are agencies allowing GEO to be framed as an SEO add-on? A practical argument for training the team, building a cross-functional operating model and piloting the service before putting it in the pitch deck.
Read the articleThousands of marketing emails, most of them the same five tips in a new jacket. Here are the ones worth your inbox – 40+ ranked across four tables: the best free marketing newsletters in the UK, the best marketing blogs in Europe, the best AI marketing newsletters, and the best in the world. Plus an FAQ on starting your own.
Read the articleEvery single review of The Oxford AI School published on Trustpilot is a five-star review. The launch announcement in full – why a marketing veteran started a school to teach basic AI to farmers, solicitors, publicans and small business owners, what the training costs, and the verified feedback from the people who have already been through it.
Read the announcementYour team is sitting on the most powerful tool since the internet, and most of them are using it to write slightly better emails. We handed the workforce a Ferrari and watched them drive it to Lidl in second gear – 75% of AI-using businesses report better productivity, but only 12% see any more revenue. Why most corporate AI training is theatre, why ‘basic’ AI training is actually the whole game, what the best AI training for a business really looks like, and what it should cost across London and the South East.
Read the articleYour team is already using AI. The only real question is whether they are following your rules or making up their own. The fifteen questions we get asked in the room, answered in full – do I need one, is it legally required, what should it include, how do I stop staff pasting client data into ChatGPT – plus a free AI policy template you can download as a Word document and complete this afternoon.
Read the guide and get the templateMost AI policies I read were written to be filed, not followed. There is no single UK AI Act to comply with, which confuses people into either doing nothing or paying for a document nobody reads. This is the five decisions a governance framework actually has to make – approved tools, the data red line, which calls stay human, who owns it, and how you would prove any of it – plus how to get it written in a day.
Read the articleLawful, ethical and robust is the definition of trustworthy AI. Govern, Map, Measure and Manage is the method the NIST AI Risk Management Framework gives you to get there. Here is what both mean in a business with actual work to do on Monday, including how to measure whether a tool is reliable enough to use, and why alignment failures in real companies are far more mundane than the debate suggests.
Read the articleThe question that catches businesses out is never whether they are allowed to use AI. It is ‘show me what happened’, eight months later, from somebody who is not pleased. Compliance is proving it, auditing is checking it, and explainability is being able to say why. The records that make this survivable fit on a spreadsheet, and the audit takes ninety minutes twice a year.
Read the articleMost people pick the first AI tool they come across and learn as they go – then wonder why AI feels like more effort than it saves. Answer ten quick questions about your actual job and this free tool hands you a short, sensible stack: the tools worth your time, whether the free tier will do, and which model to reach for when the work matters. Plus the five layers every good AI stack has, and the data rules to follow if your work is confidential.

From unhappy CMO to start-up teacher in 24 hours: Harry explains the career pivot, pressure and purpose behind launching practical AI training for local SMEs.
Read the articleWhen people ask where to start with AI, the honest answer is: start where it saves you the most boring time, fastest. These are the five jobs we help small businesses hand to AI first — in roughly the order they pay off.
Most teams lose an hour or more a day to the inbox. Paste the message you received, tell the AI the outcome you want and the tone to use, and let it produce a first draft. You stay in control — you read, tweak and send — but you skip the blank-page part that eats the time.
Meeting notes, voice memos and rough bullet points become clean proposals, summaries and reports in seconds. The trick is to give the AI your raw material and a clear instruction about the format you need, rather than asking it to invent facts.
A single blog post or recorded talk can become a newsletter, five social posts and a short video script. AI is at its best when it is reshaping content you already have, so your marketing output multiplies without multiplying your hours.
Long PDFs, competitor websites and dense reports can be summarised into the three things you actually need to know. Tools like Claude and Perplexity are excellent here — just remember to sense-check anything you will rely on.
Spreadsheets, customer lists and survey responses can be tidied, categorised and analysed in plain English — no formulas required. This is often the task that surprises people most, because it used to need a specialist.
The takeaway: pick one of these, try it this week, and build the habit before adding the next. Most of our clients save 10+ hours per person per week once these five are in place. Want help getting started? See our AI training for business or book a free intro call.
It is the question we are asked in almost every session. The honest answer is that the three leading assistants are all excellent, and the best one is usually the one you will actually open. But here is how we help people choose.
The best-known and the most versatile all-rounder. Brilliant for brainstorming, images, voice conversations and a huge ecosystem of add-ons. If you want one tool that does a bit of everything and the widest range of features, this is a safe first choice.
Our go-to for writing, careful analysis and working with long documents. Claude tends to produce natural, thoughtful prose and is excellent when the quality and tone of the words really matter — proposals, reports, sensitive emails and detailed reading.
The natural pick if you live in Gmail, Docs and the rest of Google Workspace, because it is built right into the tools you already use. Strong for research and for anyone who wants AI woven into their existing day rather than in a separate tab.
For most individuals and small teams we suggest starting with one tool, learning it properly, and only adding a second once the first is a habit. Don't agonise over the choice — the gap between the tools is far smaller than the gap between using AI well and not using it at all. We teach all three, and help you match the tool to your actual work.
Explore our programmes to learn Claude, ChatGPT, Gemini, Perplexity and Copilot hands-on.
If your AI answers feel generic, the problem usually isn't the tool — it's the instructions. Here is the simple four-part recipe we teach in every session for getting genuinely useful results out of any AI.
Put together, a weak prompt like "write a marketing email" becomes: "You are a friendly copywriter for a small Oxfordshire bakery. Write a 120-word email announcing our new sourdough, warm and not salesy, ending with a clear call to visit this weekend." The difference in quality is night and day.
One more tip: treat it as a conversation. If the first answer isn't quite right, tell the AI what to change rather than starting again. That back-and-forth is where the real magic happens.
