Which is better for business in Australia?
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 specific task will leave you frustrated and underserved.
This guide cuts through the confusion. We explain what each tool actually is, where each one excels, where each one falls short, and how Australian business professionals can think about using 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, accessible at chat.openai.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 much more.
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 three tiers:
- Free: access to GPT-4o with usage limits
- ChatGPT Plus (~$32 AUD/month): higher limits, image generation, and data analysis features
- ChatGPT Team/Enterprise: for organisations, with additional 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, with 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 in Windows / on the web (free): a general assistant, without Microsoft 365 data access
- Microsoft 365 Copilot (paid add-on, ~$50 AUD/user/month): the full version embedded across Word, Excel, Outlook, Teams, PowerPoint, and more
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 existing workflow. You open a new tab, switch apps, or open the ChatGPT mobile app. You then copy and paste content from your work into ChatGPT, get a response, and copy it back. This context-switching adds friction every time you want AI assistance.
Microsoft 365 Copilot is inside your workflow already. When you are in Word, a Copilot button sits in the toolbar. In Outlook, Copilot appears in the reply pane. In Teams, Copilot joins your meeting. There is no switching, no copying and pasting, no interruption.
2. What they know about your work
ChatGPT knows nothing about your specific organisation unless you paste the context in. To draft a reply to a specific email, you have to paste the email. Every new conversation starts from zero.
Microsoft 365 Copilot knows your real work context. It can see the email thread you are replying to, read the document you have open, search your SharePoint for relevant files, and summarise the Teams meeting you just attended. It can answer: ‘What did we decide in last Tuesday’s strategy meeting?’
3. What they are best at
ChatGPT is better for:
- Open-ended creative or analytical tasks with no organisational context needed
- Research and explanation: ‘explain how depreciation works in Australian accounting standards’
- Writing tasks starting from scratch with no existing files to reference
- Coding assistance across a wide range of languages and frameworks
- Image generation (DALL-E integration in ChatGPT Plus)
Microsoft 365 Copilot is better for:
- Anything involving your actual work files, emails, or meeting content
- Drafting emails in Outlook where it can see the full thread context
- Summarising meetings in Teams as they happen or after the fact
- Generating presentations from documents that already exist in your M365 environment
- Analysing Excel data from your actual spreadsheets; not copy-pasted samples
4. Privacy and data handling
This is a significant consideration for Australian businesses. ChatGPT (free and Plus tiers) may use your conversations to train future AI models unless you explicitly opt out. For confidential business information, this is a meaningful risk.
Microsoft 365 Copilot operates within Microsoft’s enterprise security and compliance framework. Microsoft commits that your data is not used to train AI models. For Australian organisations, Microsoft processes data in Australian data centres (Australia East and Southeast regions).
Side-by-Side Comparison
| Feature | ChatGPT (Plus) | Microsoft 365 Copilot |
|---|---|---|
| Access to your emails | No (unless pasted in) | Yes (Outlook) |
| Access to your documents | No (unless uploaded) | Yes (Word, SharePoint) |
| Access to meeting summaries | No | Yes |
| Access to your calendar | No | Yes |
| Embedded in Office | No | Yes |
| Internet browsing | Yes (Plus) | Limited |
| Image generation | Yes (Plus) | Limited |
| Data training opt-out | Manual (settings) | Not used for training |
| Australian data residency | No | Yes (enterprise) |
| Approx. cost (AUD) | ~$32/month (Plus) | ~$50/user/month (M365 add-on) |
| Best for | General tasks, research, creative | Microsoft 365 workflows |
Can You Use Both?
The most effective AI users in business are not choosing one tool and ignoring the other. They are using each tool for what it does best.
Common workflow: Use ChatGPT to brainstorm ideas, do background research, and draft content from scratch. Use Microsoft 365 Copilot for everything that touches your actual work; emails, documents, meetings, presentations, and data in spreadsheets.
Think of it this way: ChatGPT is a brilliant, generalist assistant who knows a lot about everything but nothing about your company. Copilot is a knowledgeable assistant who has read all of your emails, attended all of 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 the cost: at approximately $50 AUD per user per month on top of existing Microsoft 365 licences, a 50-person organisation is looking at $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. 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; emails, documents, meetings, and calendar, which ChatGPT does not.
There is a free version (at copilot.microsoft.com) that functions 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 and paste or upload content for ChatGPT to work with it. Microsoft 365 Copilot has native access to your files within your organisation’s M365 environment.
For most Australian enterprises, Microsoft 365 Copilot is the more appropriate tool for confidential information. It operates within Microsoft’s enterprise compliance framework, data is not used for model training, and Microsoft 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 Copilot licence investment.
