Bottom line: Gemini and Microsoft Copilot both cost about $20 a month at the tier most people buy, so the price does not decide this — your apps do. If you live in Gmail, Docs, and Drive, pick Gemini. If you live in Word, Excel, Outlook, and Teams, pick Copilot. Both have genuinely usable free tiers, so try free first.

What is Gemini best at?
Gemini is Google’s assistant, and its advantage is reach across Google’s products. On Google AI Pro ($19.99/month) you get the frontier Gemini models, a 1-million-token context window for very long documents, Deep Research reports, and Gemini inside Gmail, Docs, and Meet, bundled with Google One storage. The free tier is enough for everyday questions, summaries, and drafting. If your files already live in Drive and your inbox is Gmail, Gemini can work directly with that material instead of asking you to upload copies.
What is Copilot best at?
Copilot is Microsoft’s assistant, built around Microsoft 365. The free version at copilot.microsoft.com handles web chat, search, image generation, and voice with no subscription. Copilot Pro ($20/month) adds priority model access and Copilot inside Microsoft 365 Personal and Family apps. For workplaces, Microsoft 365 Copilot (about $30/user/month on top of an eligible Microsoft 365 plan) grounds answers in your Teams chats, Outlook mail, and SharePoint files, and can recap meetings and draft from your documents. If your day is Word, Excel, and Teams, that grounding is the feature that matters.
How do the free tiers compare?
Both free tiers are real products, not demos. Gemini free suits Google users who want a capable general assistant. Copilot free is a strong pick if you want web-grounded answers and image generation without paying, even before any Microsoft 365 subscription. Neither free tier gives you the full in-app experience: Gemini’s deepest Workspace features and Copilot’s in-document features sit behind the paid plans.
Which should you pick?
Pick Gemini if you use Gmail, Docs, and Drive, work with very long documents, or want Deep Research and video generation in the same subscription. Pick Copilot if you use Word, Excel, PowerPoint, Outlook, or Teams daily, or your employer runs Microsoft 365 — the in-app help saves more time than a slightly better chatbot. Pay for neither yet if the free tiers cover your use; upgrade only when you hit a limit that costs you time. Paying for both rarely makes sense unless you genuinely work in both suites.
