Silent Highlight — Web & PDF Highlighter ავტორი Profang

Tired of highlighting extensions that force you to create an account, track your reading habits, or lock basic features behind a paywall? Meet Silent Highlight.

Silent Highlight is a next-generation web and PDF highlighter built on a different philosophy: Zero Friction and Absolute Privacy. Simply install it, select text on any webpage or PDF, and start highlighting at the speed of thought. No sign-ups, no cloud, no lag.
