Not a generic AI tool. A system designed around how Substack writers actually grow their audience.
TYPE-FORMULA pipeline
Extracts insight types from your article (diagnostic, wisdom, contrarian), then applies proven viral formulas to each. Not a single prompt — a structured two-stage process.
Knowledge Bank
Every insight extracted from every article is stored. Browse your knowledge base, reuse strong ideas, and spot recurring themes across your writing.
Browser extension
Schedule and post notes directly to Substack from your browser. Queue up a week of content in one session. No copy-paste between tabs.
From URL to scheduled post in minutes
Paste your Substack URL
Drop in any article URL — published or draft. QVN pulls the full text automatically.
AI extracts key insights
The TYPE stage identifies what kind of insight each idea is: diagnostic framing, counterintuitive wisdom, data-backed claim, and more.
Formulas generate the posts
The FORMULA stage applies 10+ viral structures — parallel repetition, conditional framework, bridge analogy — to each insight.
Schedule and post
Pick the notes you want, edit in the rich-text editor, then schedule with the Chrome extension or copy straight to Substack Notes.
