The best free alternatives to Microsoft Copilot

Artificial intelligence (AI) is revolutionizing daily workflows — from writing documents and handling spreadsheets to creating presentations or even programming. Microsoft Copilot is one of the most well-known AI-powered assistants, tightly integrated into the Microsoft 365 ecosystem (Word, Excel, Outlook, PowerPoint, etc.), offering significant productivity boosts through automation and intelligent suggestions.

However, Copilot is not available to everyone: as of 2025, it requires a business-level Microsoft 365 subscription, which often comes with a high price tag. The good news is that there are now several powerful free alternatives that offer similar functionality, often without vendor lock-in.

In this article, we present the best free AI tools you can use as alternatives to Microsoft Copilot, whether you’re writing text, generating formulas, analyzing data, or coding — all without spending a cent.


1. Why look for alternatives to Microsoft Copilot?

1.1 Price and licensing

  • Microsoft Copilot is not included in the standard Microsoft 365 plan.

  • In 2025, it costs $30/month per user (Microsoft 365 E3 or E5).

  • Students, freelancers, and small businesses often can’t justify this cost.

1.2 Platform lock-in

  • Copilot is tied to Microsoft’s environment.

  • If you use Google Workspace, Linux, or open-source tools, Copilot isn’t an option.

1.3 Feature availability

  • Many Copilot functions are still English-only.

  • Integration across Office apps may be inconsistent.
