## About NotesIQ

NotesIQ is a Chrome extension for Substack writers who want to understand how their Substack Notes perform. It reads your Notes through your existing Substack session and shows them in a dashboard ranked by engagement, with likes, restacks, comments and content type tracked for each Note. A Viral Alert flags a Note that takes off compared with your own baseline, and the tool keeps a longer history than Substack's own dashboard, which the site says shows only the last 90 days.

The extension also helps with timing and posting. A 7-day by 6-time-slot Best Time heatmap is built from your own posting history, alongside your current posting streak. You can compose a single Note or load a week of Notes into a queue, and NotesIQ uses Substack's own scheduler to publish them at the times you set. A Media Kit feature turns your subscriber count, top Notes and engagement into a one-page sponsor summary that can be exported from the panel.

NotesIQ is aimed at Substack creators who post Notes regularly and want to decide what to write and when based on their own numbers. The site says your Notes, profile and subscriber stats stay in your browser's storage, with no NotesIQ server receiving them, and that the product is a one-time $4.99 lifetime purchase with no subscription.

## About Slugy

Slugy is an open-source URL shortener and link analytics product. It creates branded short links on custom domains, generates QR codes for each link, and offers bio pages that replace a separate link-in-bio tool. A free UTM builder helps teams produce GA4-ready campaign URLs, and free QR code and UTM tools are also available without an account.

Beyond clicks, Slugy can attribute leads and sales to the links that drove them. Lead conversion tracking is available on the Pro plan, and sales analytics with revenue per link is available on Growth. Teams can organize links into workspaces, assign roles, and share UTM templates. The site also lists integrations with Slack, Zapier, Make, Stripe, Shopify, WordPress and Segment, and a Chrome extension for shortening the current tab.

Slugy is aimed at marketing teams, agencies and e-commerce sellers who run campaigns across influencers, ads, QR codes and email and want to know which sources bring in actual revenue. Its free plan covers basic short links and click tracking, and paid plans add more links, tracked clicks, team seats and analytics retention.
