Gammaloid is a free Chrome extension developed by Jack Kingsman. It falls under the category of Browsers and is classified as an Add-ons & Tools subcategory. This extension allows users to produce gamma frequency pulses on their screens, potentially linked to neural amyloid reduction. However, it comes with a warning that it should not be used by individuals who are photosensitive.

Gammaloid is designed to flash the screen at custom frequencies, enabling users to experiment with the possible correlation between gamma frequency flashes and amyloid load. The extension's options page allows for customizable changes in flash opacity and frequency, with the default settings being 10% opacity and 40Hz frequency.
