Meta quietly paywalls smart glasses feature that appears to run entirely on-device

Meta has quietly revised how one of its AI smart glasses' accessibility features is accessed, introducing monthly usage limits that require users to subscribe if they want extended use. The change, which was not announced through a major product update, surfaced through the company's Meta One subscription documentation and has prompted fresh scrutiny over how hardware features are increasingly being placed behind recurring paywalls.

According to information published on Meta's help pages and first highlighted by The Verge, users can continue using the company's AI smart glasses without paying for a subscription. However, certain premium capabilities now come with time restrictions, including Conversation Focus, a feature designed to make conversations easier to hear in noisy environments.

Free access capped at three hours a month

Under the updated policy, Conversation Focus is available free of charge for up to three hours each month. Users who require additional listening time must subscribe to the Meta One Premium plan, priced at $20 per month.

Even subscribers are subject to limits. The premium tier provides up to 15 hours of Conversation Focus usage during each billing cycle, while any unused time expires rather than carrying over into subsequent months.

Meta introduced Conversation Focus in December 2025 as a hearing assistance tool that amplifies voices while reducing surrounding noise. At the time, the company said the feature was intended to help users distinguish conversations in busy settings. Explaining how it works, Meta said, "You'll hear the amplified voice sound slightly brighter, which will help you distinguish the conversation from ambient background noise."

The feature can be activated through a voice command directed at Meta AI and is designed to improve speech clarity rather than function as a conventional hearing aid.

On-device processing fuels criticism

The subscription requirement has attracted attention because Conversation Focus does not appear to rely on cloud-based AI processing.

During its testing, The Verge reported that the feature continued operating even after internet access was disabled. It remained functional with Wi-Fi and mobile data turned off, as well as when the connected smartphone was switched to Airplane Mode, suggesting that processing takes place directly on the smart glasses instead of Meta's servers.

That distinction has become central to the criticism. Unlike cloud-based AI services, which incur ongoing computing costs, an on-device feature would generally require no continuous server resources. As a result, some observers have questioned the rationale behind restricting access through a subscription model.

Meta has not publicly explained why Conversation Focus now carries monthly usage limits or whether licensing expenses, hardware considerations or other factors influenced the decision. The company also has not indicated whether additional on-device capabilities could eventually become subscription-only.

The move comes as Meta continues investing heavily in artificial intelligence while reshaping its business around AI-powered hardware and software. The company has committed billions of dollars towards AI infrastructure and talent and has also implemented workforce reductions to offset rising investment costs. At the same time, it has lowered the prices of several AI smart glasses by removing Ray-Ban branding from certain models.

As AI devices become more mainstream, technology companies are increasingly exploring subscription-based revenue streams. Whether consumers will accept paying recurring fees for features that appear to run entirely on hardware they already own remains an open question.
