How do Microsoft Copilot and ChatGPT differ?
Microsoft Copilot is designed to work inside the Microsoft ecosystem, while ChatGPT is a more flexible AI tool suitable for a wide range of tasks. This article highlights the main differences and similarities between the two assistants.
- Get online faster with AI tools
- Fast-track growth with AI marketing
- Save time, maximize results
What are Microsoft Copilot and ChatGPT?
Both Copilot and ChatGPT are applications powered by large language models (LLMs). Copilot integrates directly into programs like Word, Excel, Outlook, or PowerPoint. It suggests phrasing, summarizes content, generates tables and answers questions based on the context of your files. ChatGPT is accessed through a web app or mobile app. It allows natural conversations with AI and can generate text, explain information and write code.
How do Copilot and ChatGPT compare?
| Feature | Copilot | ChatGPT |
|---|---|---|
| Provider | Microsoft (in collaboration with OpenAI) | OpenAI, independent AI research company |
| Initial release | 2023 (Microsoft 365 Copilot and GitHub) | November 2022 (ChatGPT based on GPT-3) |
| Integration | Built into Microsoft 365 apps like Teams, Outlook, Word, Excel | Web app, API, mobile apps, Custom GPTs |
| Main focus | Productivity, automating office workflows | Conversations, brainstorming, text generation, data analysis |
| Customization | Through Microsoft Graph and permissions management | Through Custom GPTs, API access and plugins |
| Multimodality | Limited (mostly text, partial Excel visualization) | Fully multimodal (text, image, file uploads in GPT-4) |
| Pricing | Requires Microsoft 365 Copilot or GitHub Copilot license | Freemium model with paid Plus plan |
What makes Copilot stand out?
Microsoft Copilot is built into familiar Office apps. You can call up the assistant in Word, Excel, Outlook or PowerPoint for context-specific help. Copilot uses your files, calendar, and emails to generate suggestions, automate tasks, and create content more efficiently. It adapts its features to the app you’re using, providing support for everyday office tasks. Unlike ChatGPT, Copilot isn’t designed for open-ended conversation. Instead, it focuses on handling specific tasks directly within your document or email. Here are some examples of what Copilot can do:
- Create reports, summaries and outlines in Word or revise existing text
- Analyze numbers in Excel, identify patterns and generate charts or pivot tables
- Draft emails in Outlook, summarize long threads and suggest replies for you to choose from
- Answer follow-up questions directly in the file or email
- Use appointments, tasks, contacts and linked content to provide precise suggestions
| Advantages | Disadvantages |
|---|---|
| ✓ Seamlessly integrates with Microsoft 365 workflows | ✗ Limited for creative tasks outside Microsoft apps |
| ✓ Uses existing data sources for context-based results | ✗ High dependency on Microsoft infrastructure |
| ✓ Saves time on repetitive tasks like writing or formatting | ✗ No customizable conversations like in ChatGPT |
| ✓ Supports individuals and teams in day-to-day tasks as an alternative to ChatGPT without the need for additional software or integrations | ✗ Data is stored in the US, which may not meet the stricter privacy standards required in the EU |
What features distinguish ChatGPT?
ChatGPT is a conversational AI tool that can answer questions, generate text and assist with both technical and creative work. You can ask it to explain complex topics step by step or generate custom content. GPT-4 extends this further by analyzing files, reading PDFs and interpreting images. You can also build tailored versions of ChatGPT for specific needs. As one of the leading AI websites, ChatGPT is widely used across marketing, content creation, programming and customer support.
Unlike Copilot, ChatGPT doesn’t have access to your calendar, emails, or Microsoft data. What it offers instead is greater flexibility, especially for creative, exploratory, or less structured tasks. Here are some examples of what ChatGPT can do:
- Write emails, product descriptions, blog posts, social media copy or presentations
- Generate and debug code in Python, JavaScript, HTML, C# and more
- Answer specialized questions in areas like history, science, mathematics and IT
- Analyze Excel spreadsheets as an alternative to Copilot, extract PDF content, summarize content or describe uploaded images
- Act as a role-specific assistant, such as a marketing consultant, career coach or language trainer and brainstorming partner through Custom GPTs
| Advantages | Disadvantages |
|---|---|
| ✓ Handles a wide range professional tasks from writing to coding | ✗ May produce inconsistent or incorrect answers with complex queries |
| ✓ Customizable with plugins or tailored GPTs | ✗ Lower data privacy compared to European AI assistants |
| ✓ Strong in creative tasks like brainstorming, storytelling and writing ad copy | |
| ✓ Works with multiple formats (text, image, tables, PDFs) in a single session and provides structured responses |
