Microsoft's terms of service refer to Copilot as 'for entertainment purposes only' in light of a decline in adoption.

      In summary: Microsoft has invested billions in integrating Copilot throughout its product lineup, promoting it as a vital AI colleague. However, its own Terms of Use convey a different message. A clause discreetly included in the document states that Copilot is “for entertainment purposes only” and warns users against depending on it for significant advice. This disparity between promotional claims and the legal terminology has attracted renewed scrutiny as adoption statistics show that less than one in 30 eligible users are actually subscribing to the tool.

      Nestled between Satya Nadella’s earnings calls and the product descriptions that say they will “transform the way you work,” Microsoft inserted a statement into Copilot’s Terms of Use that significantly contrasts with its AI marketing. Updated in October 2025 and gaining widespread visibility in early April 2026, the clause is placed under a prominently bold section titled “IMPORTANT DISCLOSURES & WARNINGS.” It states: “Copilot is for entertainment purposes only. It can make mistakes, and it may not work as intended. Don’t rely on Copilot for important advice. Use Copilot at your own risk.”

      The same document asserts that Microsoft makes no guarantees regarding Copilot and warns users not to assume its outputs are free from copyright, trademark, or privacy rights issues, making users solely responsible for any content they choose to share or publish using Copilot. These terms pertain to consumer Copilot products, while the enterprise-focused Microsoft 365 Copilot is excluded from this clause.

      The public message from Microsoft stands in stark contrast to years of vigorous promotion. Since the integration of Copilot into Windows 11 and the Microsoft 365 suite in 2023, the company has marketed the tool as a productivity booster, referring to it as an “AI companion” for users of Word, Excel, PowerPoint, and Outlook. Nadella has characterized Copilot as “becoming a true daily habit” and told investors that daily active users had increased nearly threefold year-over-year. The company allocated roughly $80 billion for AI-related capital expenditures in the fiscal year 2025, which included a $13 billion investment in OpenAI, the foundation for Copilot's core functionalities.

      Microsoft 365 Copilot costs $30 per user monthly as an enterprise add-on, with a business tier priced at $18 per user per month. Premium consumer plans can cost tens of dollars per month. The phrase “for entertainment purposes only” is not typically associated with products that carry such fees.

      The legal rationale behind the clause has been analyzed by legal experts offering a cautious interpretation. The predominant interpretation suggests that this clause is a legal safeguard aimed at limiting liability when the product does not perform as expected, an overreaction that has become embarrassing due to its blunt contradiction of promotional messages. Similarly, OpenAI, Google, and Anthropic feature comparable disclaimers in their service agreements, acknowledging potential inaccuracies and placing the burden of verifying outputs on users. However, none of them specifically use the phrase “entertainment purposes only,” described by Android Authority as “the same disclaimer that psychics use to avoid litigation.”

      The broader legal situation is significant. Microsoft has previously faced lawsuits over Copilot’s outputs: a class action in a U.S. federal court in San Francisco questioned the legality of GitHub Copilot for alleged open-source license breaches, and another dispute in Australia involved customers shifted to pricier plans that included Copilot. From this perspective, the consumer Copilot Terms of Service language is an expression of corporate caution, an effort to clearly state that the product was never intended to be relied upon by users.

      The adoption statistics further contextualize this situation. Data released in early 2026 indicated that only 3.3% of Microsoft 365 and Office 365 users with access to Copilot Chat actually pay for it. Out of approximately 450 million Microsoft 365 accounts, only 15 million are paid Copilot subscribers, reflecting the challenge of convincing current users to pay a notable premium for AI they find unreliable.

      Research from Recon Analytics attributed some of the issues to accuracy. Its assessment of Copilot’s accuracy Net Promoter Score revealed a score of -3.5 in July 2025, dropping to -24.1 by September 2025, and slightly recovering to -19.8 by January 2026. Among surveys of previous Copilot users, 44.2% cited distrust in its responses as the main reason for discontinuing use. Additionally, the U.S. paid subscriber market share plummeted from 18.8% in July 2025 to 11.5% in January 2026, a 39% decrease in just six months. When presented with choices among Copilot, ChatGPT, and Gemini, only 8% of workers selected Copilot.

      The record of inaccuracies has not improved perceptions. In August 2024, Copilot inaccurately accused German court reporter Martin Bernklau of crimes he had covered for years, labeling him a convicted
