Posts get a 1-5 score based on actionable insights, originality, and information density. You can customize the rubric in settings: tell it what topics you care about, what signals to prioritize, and what to deprioritize.
Basic analysis ($0.10) gives you score, synopsis, quotes, and comment drafts. Research verification ($0.25) adds AI-powered fact-checking for posts making claims about current events or data.
Because I hate subscriptions. You shouldn't pay monthly for something you might use casually. Add credits when you need them, use them when you want.
Not yet; the tool can only analyze publicly accessible content. Analyzing posts you're subscribed to is a future feature.
Your voice profile and scoring rubric are stored so you don't have to re-enter them. Analysis history stays in your browser locally; I'm not harvesting your data for anything.
Yes. In settings, you can specify topics you care about (score higher), bonus signals to reward, and things to deprioritize. The scoring adapts to what matters to you.
They're starting points, not final drafts. You set up a voice profile describing how you actually write: your tone, your go-to moves, and what you avoid. The drafts match that. Edit as much or as little as you want before posting.
Every post you analyze gets logged: URL, title, score, synopsis, and which comment you copied (if any). It's a feedback loop to track what's working. All stored locally in your browser.
You followed those writers for a reason. Substack Analyzer helps you get back to actually reading the best of what they publish, without the guilt of an overflowing inbox.
