Find out why your Substack isn't growing.

Paste any Substack URL (yourname.substack.com, substack.com/@you, or a post URL) - or paste publication text for paywalled/private pubs. Get a transparent 0-100 DiscoverScore across 7 dimensions plus copy-ready name, tagline, About, and post-title rewrites in under 3 minutes. No login.

How it works

RSS is the primary structured source (name, tagline, post titles + dates). Public HTML adds logo, cover, social links, Notes and Recommendations signals. A 2-hour cache keeps re-audits instant.

2. Score

0-100 DiscoverScore from 7 dimensions with every point explained.

3. Fix

Copy-ready name, tagline, About, and 5 post-title rewrites + checklists.

4. Re-audit

Make the edits, paste again, watch your delta move.
