Is Speechify — Text to Speech Safe? — Extension Safety Profile

This extension can read and change data on every website you visit, including local files, because it requests broad host permissions. It can also capture audio from your browser tabs, modify context menus, and run scripts on pages. For a text-to-speech tool, requesting access to all URLs and the ability to capture tab audio is somewhat expected, as it needs to read page text to convert it to speech and may offer features like highlighting or media controls. However, the scope is extensive and a careful user should be aware that any extension with this level of access could technically see sensitive information displayed in the browser.

General-purpose browser extensions that interact with all web content carry inherent privacy considerations. A user should understand that the developer’s stated data collection includes personally identifiable information and website content. While the publisher declares this data is not sold or used for unrelated purposes, the extension’s functionality requires processing the text of pages you visit, which could include private messages, emails, or financial details if used on those sites.

The fact sheet shows this extension’s strongest dimension is Community Reputation, reflecting a high store rating and large user base. The weakest dimension is Permissions & Access, which aligns with the broad and powerful permissions it requests. The overall safety score is in the B range, suggesting a generally positive but not perfect assessment based on publicly documented factors.
