Gemini vs Microsoft Copilot
Gemini scores 77 to Microsoft Copilot's 25 on public evidence for email writing & inbox management, and they rank #1 and #3 there. Both are free to start. Numbers below are the same public signals the ranking uses, recomputed nightly — nothing here is sponsored.
Gemini
Google's assistant with Deep Research reports, Gmail/Docs/Drive integration and YouTube video understanding.
+ Deep Research produces long cited reports from dozens of sources, and it reads your Gmail, Drive and Calendar directly when you allow it.
− Quality swings between Flash and Pro models, and it refuses or hedges on some topics more than competitors.
Microsoft Copilot
Microsoft's assistant, free on the web and Windows, and embedded in Word, Excel, PowerPoint, Outlook and Teams with Microsoft 365 Copilot.
+ Works inside the Office apps you already use, drafting Outlook replies, summarizing Teams meetings and turning Word docs into PowerPoint decks.
− Results inside Excel and PowerPoint are often shallow compared with the standalone chat, which makes the $30 business seat hard to justify.
