Active

Overview

Readless is an AI-powered tool that consolidates RSS feeds and email newsletters (Substack, beehiiv, Ghost, Kit) into a single scheduled digest delivered to the inbox. It uses Claude Sonnet 4.5 for summarization, duplicate removal, hot topic detection, and trend synthesis, reducing reading time by approximately 90% (e.g., 80 minutes to 10 minutes). It targets users overwhelmed by multiple newsletter subscriptions who seek efficient insights without reading everything.
