Free tier: Copilot's biggest advantage
Microsoft Copilot's free tier punches well above its weight. You get GPT-4 (not GPT-4o mini) plus always-on Bing web search at no cost. That means current information in every response without paying a cent. ChatGPT's free tier gives GPT-4o mini — functional but noticeably less capable. For casual users who want to ask questions, summarize articles, or draft emails, Copilot free is genuinely the better deal.
Microsoft 365 integration: Copilot Pro's killer feature
If you live in Word, Excel, PowerPoint, or Teams, Copilot Pro ($30/mo) is transformative. Ask it to draft a report from a brief, analyze spreadsheet data in natural language, or summarize a 90-minute Teams meeting you missed. ChatGPT has no access to your Office files — you'd need to copy-paste content manually. For knowledge workers in M365 environments, this gap is decisive.
Pricing breakdown
At the consumer level:
ChatGPT free: GPT-4o mini · no web search by default
ChatGPT Plus ($20/mo): GPT-4o · DALL-E 3 · Advanced Voice · GPT Store
Copilot free: GPT-4 · Bing search always-on · limited image gen
Copilot Pro ($30/mo): GPT-4 Turbo · M365 integration · more image gen
Copilot Pro is $10/mo more than ChatGPT Plus, but adds M365 Office integration that ChatGPT cannot match at any price.
Frequently asked questions
Is ChatGPT better than Microsoft Copilot in 2026?
For raw AI capability, ChatGPT with GPT-4o is stronger — better reasoning, more plugins, persistent memory. For Microsoft 365 users, Copilot's deep Office integration makes it the clear winner for daily workflows. Copilot also offers a more generous free tier with GPT-4 and Bing search, while ChatGPT free gives only GPT-4o mini.
What's the difference between ChatGPT and Microsoft Copilot?
ChatGPT is OpenAI's standalone AI assistant at chat.openai.com — optimized for general-purpose use with GPT-4o, plugins, and a rich ecosystem. Microsoft Copilot at copilot.microsoft.com is Microsoft's AI (powered by GPT-4) with always-on Bing search, baked into Windows 11 and Microsoft 365. They share OpenAI's underlying models but serve completely different ecosystems.
Is Microsoft Copilot free?
Yes — copilot.microsoft.com is free with GPT-4 and Bing web search included. Copilot Pro at $30/mo adds Microsoft 365 integration (Word, Excel, PowerPoint, Teams) and more image generations. This makes Copilot's free tier more capable than ChatGPT's free tier (GPT-4o mini, limited search) for casual everyday use.
Which is better for Microsoft Office?
Microsoft Copilot Pro is significantly better for Office — it integrates natively into Word, Excel, PowerPoint, and Teams, accessing your actual files and meeting transcripts. ChatGPT has zero access to your Office documents without manual copy-pasting. If M365 integration matters to you, Copilot Pro is the only real option; ChatGPT cannot compete here at any price.
