💡 Which should you start with?
- Use ChatGPT if you want the most versatile general-purpose tool and don't need deep Office integration
- Use Copilot if your company runs on Microsoft 365 — it works inside Outlook and Word
- Use Gemini if your company uses Google Workspace — it integrates with Gmail and Google Docs
For this course, you can follow along with any of the three. The concepts and prompt techniques work across all platforms.
Free vs. Paid: Do You Need to Pay?
For most administrative tasks — drafting emails, creating documents, summarizing meetings — the free tiers are sufficient. Paid plans are worth it if you:
- Use AI heavily (50+ times per day) and hit free-tier limits
- Need direct integration inside Office apps or Google Workspace
- Need to upload large files or process long documents regularly
- Want access to the most advanced models for complex tasks
