Which we'd pick, scenario by scenario
A 5-person agency writing custom content and building custom workflows
ChatGPT. The custom GPT builders and Deep Research tools on the $20 a month tier provide superior raw generation and web crawling.
A corporate team deeply embedded in Excel, Word, and Teams
Copilot. Paying $18.00 user a month (paid yearly) embeds AI directly where their files live, eliminating the friction of manual copying.
A business needing strict data privacy on a budget with basic chat needs
Copilot. Eligible Microsoft 365 plans include Copilot Chat at no additional cost, keeping chats secure and inside the tenant boundary.
Our take
This choice is rarely about pure intelligence and always about workflow context. ChatGPT is a standalone destination. When your team needs to write deep analytical briefs, crawl the web with Deep Research, or spin up custom GPTs, ChatGPT Plus at $20 a month is unbeatable. It operates as a brilliant, isolated analyst. However, if your data lives in SharePoint and your team spends six hours a day in Excel, Outlook, and Teams, ChatGPT becomes a copy-paste chore. This is where Microsoft Copilot excels. By adding Copilot to an eligible Microsoft 365 Business plan for $18.00 user a month paid yearly, you place the model directly inside your daily files. It knows your calendar, drafts your emails, and analyzes spreadsheets. For teams already paying for Microsoft licensing, utilizing their built-in Copilot Chat at no additional cost is a natural starting point.
