ChatGPT vs Copilot: which AI assistant fits your workflow?

ChatGPT is OpenAI's standalone AI assistant. It excels at advanced reasoning, creative generation (images, video, code), deep multi-step research, and agentic tasks that run autonomously. It connects to 30+ third-party apps and works across any platform. For a deeper look at its capabilities, see our ChatGPT overview.

Microsoft Copilot is an AI layer embedded across Microsoft 365, Windows, and GitHub. It works inside Word, Excel, PowerPoint, Outlook, and Teams — meeting you where you already spend your day. Since January 2026, Copilot also draws on models from Anthropic, Google, and xAI alongside OpenAI, making it a multi-model system. For details on its ecosystem, see our Microsoft Copilot overview.

The biggest misconception: Copilot is not rebranded ChatGPT. They use GPT models through entirely separate infrastructure — OpenAI's systems versus Azure OpenAI — with different data handling, different privacy guarantees, and now different model providers.

Copilot's edge here is depth of integration. Agent Mode is now generally available in Word and Excel, with PowerPoint rolling out in February 2026. In Excel, teams can choose between Anthropic and OpenAI reasoning engines for different types of analysis. Outlook gets voice input and auto-reply, and Teams generates meeting summaries through its Facilitator Agent.

ChatGPT takes a different approach. Canvas provides a side-by-side collaborative editing space. File uploads pull directly from Google Drive and OneDrive, and the data analysis tool handles up to 10 files at 512 MB each — roughly ten times the consumer Copilot's 50 MB file limit.

Both tools offer persistent collaborative workspaces, but they work differently. Copilot Pages is a real-time multiplayer canvas integrated into the M365 ecosystem — think shared whiteboard that stays alive. ChatGPT Canvas is a side-by-side drafting environment focused on iteration between you and the AI.

ChatGPT's Deep Research is the standout. It deploys the o3 reasoning model on multi-step internet research tasks that take 5 to 30 minutes, producing detailed reports with citations. It can connect to external apps and MCP servers, pulling in data from tools your team already uses. Agent Mode goes further — it completes complex online tasks like filling forms and editing spreadsheets autonomously.

For Pro subscribers ($200/mo), Pulse delivers daily asynchronous research briefs, turning ChatGPT into an always-on analyst.

Copilot offers its own multi-page research reports, but they stay within the Microsoft ecosystem. The strength here is that Copilot's research draws on your M365 data — emails, documents, Teams conversations — through Microsoft Graph and the Semantic Index.

ChatGPT leads in creative output. Plus and Pro subscribers get Sora 2 video generation — Plus with 1,000 monthly credits (720p, up to 20 seconds), Pro with 10,000 credits at higher fidelity (up to 4K, 90 seconds) plus unlimited relaxed-mode generation. The GPT image models handle generation and editing. Advanced Voice works across mobile, desktop, and web. ChatGPT Atlas provides a dedicated AI-powered browser (macOS only). Shopping Research with Instant Checkout — currently supporting Etsy, with Shopify integration coming — is a feature no competitor offers.

Copilot counters with accessibility. Designer and Copilot Imagine provide 15 free image generation boosts per day — a more generous free tier than ChatGPT's. Copilot Voice supports 50+ languages with an animated interface. On Copilot+ PCs, the camera, Edge browser, and Windows screen analysis provide vision capabilities tightly woven into the operating system.

This is where the "Copilot" brand gets confusing. GitHub Copilot and M365 Copilot are entirely separate products with separate pricing and target audiences. If you are weighing GitHub Copilot vs ChatGPT for development work, here is what matters.

ChatGPT Codex is an agentic coding tool. Each task runs in its own cloud sandbox with access to your repository. The GPT-5.3-Codex model (launched 5 February 2026) runs roughly 25% faster than its predecessor. Codex creates pull requests from issues and can run multiple agents in parallel. Plus ($20/mo) and Business ($25/seat/mo) plans include it.

GitHub Copilot is a real-time IDE companion. It provides inline code completions, next-edit predictions, and agent mode within VS Code, JetBrains, and other IDEs. The free tier offers 2,000 completions per month. A key differentiator: GitHub Copilot supports 25+ models from five providers (OpenAI, Anthropic, Google, xAI, and Raptor mini), giving developers model choice that ChatGPT Codex does not offer. For more on AI for developers, see our dedicated training paths.

The distinction is functional: ChatGPT Codex handles task-based agentic work (build this feature, fix this bug). GitHub Copilot handles real-time inline assistance as you type.

Pricing is where this comparison gets tangled. Both tools offer multiple tiers aimed at different users, and Copilot's add-on model means the sticker price does not tell the full story.

Consumer tiers

Business tiers

Developer tiers

The hidden cost: Copilot's business tiers are add-ons. M365 Copilot Business at $21/user/mo requires a separate Microsoft 365 subscription. ChatGPT Business at $25/seat/mo is standalone — no additional license needed. When you factor in the base M365 license, Copilot's total cost of ownership can exceed ChatGPT's, depending on your existing subscriptions.

Freshness note: M365 commercial subscription prices increase on 1 July 2026 (for example, M365 E3 rises from $36 to $39/user/mo). The Copilot Business promotional rate of $18/user/mo runs through 31 March 2026. Prices verified 13 February 2026.

Here is the rule that applies to both tools: consumer tiers use your data for model training by default. Business and enterprise tiers do not.

On both platforms, you can opt out of consumer data training. But the default matters — most individual users never change it. If data privacy is a priority, paid business tiers on either platform are the baseline.

ChatGPT enterprise security

ChatGPT Enterprise provides SAML SSO, SCIM provisioning, and customer-controlled encryption keys (EKM). Data residency spans 10 regions, including the US, Europe, UK, Japan, and Canada. The Compliance API supports eDiscovery and DLP. Certifications include SOC 2 Type 2, ISO 27001/27017/27018/27701, and CSA STAR. A Business Associate Agreement covers HIPAA compliance. See OpenAI's enterprise privacy page for the latest details.

M365 Copilot enterprise security

M365 Copilot inherits Microsoft's enterprise infrastructure. Authentication runs through Entra ID natively — no separate SSO configuration. Data residency covers the EU Data Boundary plus in-country processing for 15 locations, with expansion planned through 2026. Microsoft Purview provides DLP, Insider Risk Management, and eDiscovery. Certifications include SOC 2 Type 1, ISO 27001/27701/22301/27018/42001 (42001 covers AI management systems specifically). M365 compliance covers HIPAA. Microsoft's Copyright Commitment means the company defends and pays for adverse judgments when customers use built-in content guardrails.

The Anthropic wrinkle: Since January 2026, Anthropic serves as an official subprocessor for M365 Copilot. Anthropic currently processes data outside the EU Data Boundary, and admins must activate Anthropic models through admin controls. EU-based organizations should verify this fits their compliance requirements.
