If you have been exploring AI tools at work, you have almost certainly come across both Microsoft Copilot and ChatGPT. They look similar on the surface: you type a prompt, the AI generates a response, and both are powered by technology from OpenAI. But underneath, they are designed for very different purposes, and choosing the wrong one for a task will leave you frustrated.
This guide explains what each tool actually is, where each one excels, where each falls short, and how Australian business professionals can use both, because the answer to “which is better?” is almost always “it depends on what you are doing.”
What Is ChatGPT?
ChatGPT is a standalone AI assistant created by OpenAI, available at chatgpt.com or via the ChatGPT app. You log in, start a conversation, and the AI responds to prompts: answering questions, drafting text, writing code, summarising content you paste in, generating images, and more. As of 2026 its default model is GPT-5.5, OpenAI’s latest general-purpose model.

ChatGPT is a general-purpose tool. It has no direct connection to your work email, your documents, your meetings, or your organisation’s systems. When you interact with ChatGPT, you are working with a capable but contextless AI: it knows an enormous amount about the world in general, but nothing specific about your workplace unless you tell it.
ChatGPT is available in several tiers (prices in AUD, current as of July 2026):
- Free: access to GPT-5.5 with usage limits
- ChatGPT Plus (~$35/month incl GST): higher limits, image generation, advanced data analysis, and priority access
- ChatGPT Pro: a premium tier with the highest limits and access to the most capable models
- ChatGPT Business / Enterprise: for organisations, with added privacy controls and admin tools
What Is Microsoft Copilot?
Microsoft Copilot is an AI assistant built directly into Microsoft 365, the suite that includes Word, Excel, PowerPoint, Outlook, Teams, OneNote and SharePoint. Rather than being a separate tool you switch to, Copilot lives inside the software you already use every day.
The critical distinction is that Microsoft 365 Copilot has access to your organisational data, within your existing security permissions, which means it can reference your actual emails, documents, calendar, meeting transcripts and internal content when generating responses.
Microsoft Copilot is available as:
- Copilot (free): a general web/Windows assistant, without Microsoft 365 data access
- Microsoft 365 Copilot (paid add-on, approximately AUD $45 to $50 per user per month): the full version embedded across Word, Excel, Outlook, Teams and PowerPoint
Pricing note (July 2026): AI pricing changes often. Microsoft ran a lower promotional rate for its small-business Copilot add-on that ended on 30 June 2026, and Australian Microsoft 365 pricing was adjusting from July 2026. Always confirm the current rate on Microsoft’s official pricing page before budgeting.

Note: when most business professionals refer to “Copilot at work”, they mean Microsoft 365 Copilot, the paid, data-connected version. That is the version this article focuses on.
The Four Biggest Differences
1. Where they live
ChatGPT sits outside your workflow: you switch tabs or apps, paste content in, get a response, and paste it back.
Microsoft 365 Copilot is already inside your workflow: a Copilot button in the Word toolbar, in the Outlook reply pane, in your Teams meeting. No switching, no copy-paste.
2. What they know about your work
ChatGPT knows nothing about your organisation unless you paste it in; every conversation starts from zero.
Microsoft 365 Copilot can see the email thread you are replying to, read the document you have open, search SharePoint for relevant files, and summarise the Teams meeting you just attended.
3. What they are best at
ChatGPT is stronger for open-ended research, explanation, from-scratch writing, coding across many languages, and image generation.
Microsoft 365 Copilot is stronger for anything involving your real files, emails or meetings: drafting Outlook replies with full thread context, summarising Teams meetings, building presentations from existing documents, and analysing your actual Excel data.
4. Privacy and data handling
ChatGPT‘s consumer tiers may use your conversations to improve models unless you opt out, a real consideration for confidential information.
Microsoft 365 Copilot operates within Microsoft’s enterprise security and compliance framework, does not use your data to train models, and processes data in Australian data centres (Australia East and Southeast).

Can You Use Both?
The most effective AI users are not choosing one tool and ignoring the other; they use each for what it does best.
A Common workflow: use ChatGPT to brainstorm ideas, do background research and draft content from scratch, and use Microsoft 365 Copilot for everything that touches your actual work, emails, documents, meetings, presentations and spreadsheet data.
Think of it this way: ChatGPT is a brilliant generalist who knows a lot about everything but nothing about your company. Copilot is a knowledgeable assistant who has read all your emails, attended all your meetings, and knows exactly where your files live.
Which Should Your Organisation Invest In?
For most Australian businesses already running Microsoft 365, the answer is to invest in Microsoft 365 Copilot first, because it delivers value inside tools your team already uses every day, with a security model that meets enterprise requirements.
The practical hurdle is cost. At roughly AUD $45 to $50 per user per month on top of existing Microsoft 365 licences, a 50-person organisation is looking at around $30,000 per year. That makes training critical: an untrained workforce using Copilot generates mediocre outputs and concludes the tool is not worth the investment, while a trained workforce can realistically save hours per person per week.
Frequently Asked Questions
No. Both are powered by large language models from OpenAI, but they are different products. ChatGPT is a standalone general-purpose AI assistant. Microsoft 365 Copilot is embedded inside Microsoft 365 applications and has access to your organisational data, which ChatGPT does not.
There is a free version (at copilot.microsoft.com) that works similarly to ChatGPT but without Microsoft 365 data access. The full Microsoft 365 Copilot, which works inside Word, Excel, Outlook and Teams, requires a paid add-on licence.
Not directly. You need to copy, paste or upload content for ChatGPT to work with it. Microsoft 365 Copilot has native access to your files within your organisation’s Microsoft 365 environment.
For most Australian enterprises, Microsoft 365 Copilot is more appropriate for confidential information. It operates within Microsoft’s enterprise compliance framework, does not use your data for model training, and offers data residency in Australian data centres.
Yes. Both tools require skill to use well, but Copilot’s outputs are highly sensitive to prompt quality. Organisations that invest in structured Copilot training consistently report faster adoption, better outputs, and stronger return on their licence investment.
