The Fundamental Difference: Assistant vs Agent
Microsoft Copilot
AI Assistant
Copilot works like a smart assistant sitting next to you. It can understand your questions, suggest formulas, and help you analyze data. But you execute every action.
Example workflow:
- 1. You: "Help me clean this data"
- 2. Copilot: "I suggest removing duplicates in column A"
- 3. You: Click to confirm
- 4. Copilot: "Now let's standardize the dates"
- 5. You: Click to confirm
- 6. ... (repeat for each step)
Best for:
- • Learning Excel with AI guidance
- • Users who want control over every action
- • Teams already invested in Microsoft 365
- • Use across Word, PowerPoint, Teams, etc.
ElyxAI

Example workflow:
- 1. You: "Clean this sales data, remove duplicates, fix the date formats, create a monthly pivot table, and add a chart showing the trend"
- 2. ElyxAI: Executes all steps automatically
- 3. Done. ✓
Best for:

Frequently Asked Questions
Can I use both ElyxAI and Copilot together?
Yes! They serve different purposes. Use Copilot for general Microsoft 365 productivity (emails, documents, presentations) and ElyxAI specifically for Excel automation and heavy data work.
Does ElyxAI work with Microsoft 365 Excel?

Why is ElyxAI cheaper than Copilot?
