# Newsletrix - AI-powered newsletter competitor intelligence > Newsletrix is a web platform that automatically analyzes competitor newsletters with AI. It extracts subject-line patterns, SWOT analysis, CTA and link intelligence, send-time heatmaps, and content recommendations - so marketers, creators, and agencies can replace guesswork with data-backed decisions. Newsletrix is a SaaS competitor-intelligence tool focused only on email newsletters. Each account gets a unique forwarding address; subscribe to any newsletter with it and every send is analyzed within minutes across 50+ normalized dimensions. There is nothing to install and no integration with sending platforms is required - if a newsletter reaches an inbox (Substack, Beehiiv, Mailchimp, ConvertKit, Klaviyo, or a custom sender), Newsletrix can analyze it. All plans include the full feature set and differ only in newsletters analyzed per week: Free $0 (2/week, no credit card), Basic $9/mo (5/week), Standard $29/mo (15/week), Business $69/mo (50/week). All paid plans are month-to-month and cancellable from the dashboard. A built-in Model Context Protocol (MCP) server lets Claude, ChatGPT, Cursor, and other MCP clients query account data, and is available on every plan including the free tier.
