Is Text to Speech TTS AI | Readvox Safe? — Extension Safety Profile

This extension requests permissions typical for a text-to-speech tool, including reading and modifying text on any website you visit (activeTab and <all_urls>, plus scripting), adding a context menau item, saving settings locally, and using offscreen audio playback. It also requests system.cpu and system.memory — less common for TTS — which may allow it to monitor performance to adjust playback. While the broad host access is expected for reading pages aloud on command, the system resource monitoring is unusual and not strictly necessary for core functionality.

Because text-to-speech extensions process the words you see on screen, they can access sensitive data, from private messges to financial details. A careful user should understand that the declared data collection (Website content) means this extension may transmit page text to a third-party service for voice synthesis. Users in this category should also be wary of lookalike extensions and only install from reputable sources.

The strongest indicator is Data & Privacy, where the developer's stated practices — including not selling data and not using it for unrelated purposes — scored well. The weakest is Publisher & Identity, suggesting the company behind the extension (Fenvox LLC) has limited public trust or track record. While the privacy promises are strong on paper, the publisher's lower visibility may give a cautious user pause before granting extensive page-reading access.
