Overview and chatbots

A practical introduction to generative AI and three general-purpose assistants: ChatGPT, Gemini and Claude.

Prepare

Before you begin

Use an account and browser approved for your workplace. The safest first exercise uses material you could comfortably share in public.

Choose safe material

Do not paste confidential, personal or sensitive information unless your organisation has explicitly approved the service for it.

Keep responsibility

You remain responsible for decisions, claims and work produced with AI assistance.

Verify what matters

Check facts, quotations, calculations, references and anything that could affect another person.

Start well

A useful first prompt

Good prompting is less about secret formulas and more about making the task understandable. Give the assistant enough context to help.

Five useful ingredients
GoalWhat should be achieved?ContextWhy and for whom?MaterialWhat should it use?FormatWhat should the answer look like?ConstraintsWhat must it avoid or respect?
I am preparing a short briefing for colleagues who are new to generative AI. Explain three useful ways it could support everyday knowledge work. Use plain English, give one concrete example for each, and finish with two limitations we should discuss.

After the first answer, continue the conversation: ask for clarification, challenge an assumption, request a different format, or provide an example of what “good” looks like.

Three environments

Get started in each service

Begin in the web version. Interfaces change frequently, so button names may differ slightly; the basic working pattern remains the same.

ChatGPT

Start a broad, flexible conversation

A strong general starting point for drafting, explaining, analysing files, searching and developing work over several turns.

Screen guide based on the current account page. Exact buttons may change.

Create an account — step by step

  1. Open chatgpt.com and choose Log in or sign up.
  2. Choose Google, Apple or enter an email address. A personal email is simplest unless your organisation provides an approved account.
  3. If you used email, open the verification message and confirm the address.
  4. Complete any name, age or terms prompts. Stop if your organisation’s policy does not allow a personal account for work data.

Try the service

  1. Select New chat, then paste the example prompt above or describe a real, non-sensitive task.
  2. Read the answer critically. Ask: “What assumptions did you make?” and request one revision.
  3. If upload is available, add a safe document and say exactly what to extract, compare or improve.
Free and desktop: Free supports everyday chat plus limited access to files, data, images and research. Plus mainly adds higher limits, stronger models, and broader Work/Codex computer interaction. Native apps are available for macOS and Windows.

Gemini

Explore multimodal work and Google connections

Especially useful when your work already involves Google services, web material, images or other media.

Screen guide based on the current account page. Exact buttons may change.

Create an account — step by step

  1. Open gemini.google.com and select Sign in.
  2. Choose an existing eligible Google account, or select Create account and choose personal or work use.
  3. Enter your name, date of birth and a new Gmail address—or use an existing email—then create a strong password.
  4. Confirm the phone or email checks Google requests. Work or school accounts may require administrator activation.

Try the service

  1. Enter the same first prompt, then ask Gemini to turn its answer into a checklist for a workplace situation.
  2. Use Add files when available to try a safe image or document.
  3. Compare the response with ChatGPT: notice structure, tone, useful detail and unsupported claims.
Free and desktop: Gemini has a generous free starting point and is connected to tools such as Canvas, Gems and NotebookLM. Google AI Pro mainly adds much larger context, higher limits and deeper research/media access. A Windows desktop app is available; on Mac use the web or Chrome integration where available.

Claude

Develop careful, sustained work

Often effective for close reading, thoughtful revision, long-form reasoning and coding tasks that benefit from a steady working context.

Screen guide based on the current account page. Exact buttons may change.

Create an account — step by step

  1. Open claude.ai and select Google, Apple or email.
  2. If you choose email, enter the address and select Continue with email.
  3. Open the sign-in link or code Anthropic sends to your inbox.
  4. Confirm the requested profile and terms. Use only safe material until your organisation has approved the account and service.

Try the service

  1. Start a new conversation with the same first prompt. Ask Claude to identify uncertainties before drafting.
  2. Paste a short, safe piece of writing and ask for feedback against two criteria you define.
  3. Request a revised version and a short explanation of the most important changes.
Free and desktop: Claude Free supports writing, coding, analysis and web search within a rolling allowance. Pro mainly adds at least five times more use, Cowork, more projects and larger workflows. Claude Desktop is available for macOS and Windows; Microsoft 365 and Chrome connections depend on plan and administration.

Practical workshop

Try one task three ways

Work individually or in pairs. Use the same safe task and source material so that differences between services become visible.

Round 01 · ChatGPT

Shape the task

Give context and a requested format. Use two follow-up turns to improve the result.

Round 02 · Gemini

Change the medium

Add a safe file or image, or ask for a visual way to organise the same content.

Round 03 · Claude

Interrogate quality

Ask for uncertainties, critique against criteria, and a carefully justified revision.

Reflect

Compare what you notice

There is rarely one universal “best” assistant. The better question is which service fits the task, risk and working context.

Look forQuestions to discuss
UsefulnessWhich response moved the task forward most effectively?
ControlWhere was it easiest to steer, correct or specify the output?
EvidenceWhich claims would need checking, and how would you check them?
FitWhat workplace task could this support—and what should remain human-led?
