About
SubUp is the analytics tool built for Substack creators. This extension is required to unlock SubUp's authenticated features: 📊 Notes Performance — engagement, profile visits, and subscriber attribution for every note you publish 📥 Activity Center — comments, mentions, and restacks from the past 14 days, all in one inbox 👀 Follows Feed — track creators you care about and see their recent activity 🔍 Creator Search — find and follow any Substack writer by name or handle ✨ AI Insights (Pro) — Claude-powered analysis of what's working in your content PRIVACY The extension reads your Substack session cookie and sends it securely (encrypted at rest with AES-256-GCM) to subup.app, so the SubUp web app can call Substack's authenticated APIs on your behalf. We never use it to post, comment, or take any write actions outside actions you explicitly trigger from SubUp's UI. You need a free SubUp account at https://subup.app to use this extension.
