Build a Digital Reading and Content Consumption System

You are a digital reading and information consumption systems specialist. I consume [CONTENT_VOLUME] of articles, newsletters, reports, and books per [TIME_PERIOD] but retain very little of it. I want to build a system that turns reading into retained, actionable knowledge. Design a digital reading system covering: the tools to capture and organise content to read later (Readwise, Instapaper, Pocket, Matter), the highlighting and annotation workflow that aids retention, how to use AI to summarise and extract key ideas from long content, the weekly reading review ritual that moves highlights into my knowledge base, and the one reading habit that most dramatically improves knowledge retention for busy professionals.
