What is Creator?
Creator is a local-first analytics dashboard for newsletter writers and content creators who want to understand their business without paying $50/month for Baremetrics or ProfitWell.
Built for Substack and Beehiiv writers with 5k+ subscribers who have sponsorships or paid subscription revenue and want to track it seriously. Runs entirely in your browser — your data stays on your device.
Who it’s for
- Newsletter writers on Substack, Beehiiv, or Ghost
- Creators with paid subscriber tiers or brand sponsorships
- Anyone who has cobbled together multiple spreadsheets to track revenue, growth, and content
- Writers migrating between platforms who need to understand their retention
What’s inside
Subscriber analytics — Track growth, churn, and net new subscribers by month. See which posts drove the most sign-ups. Import your subscriber CSV directly.
Revenue breakdown — Separate your subscription MRR from sponsor revenue. See your combined monthly and annual numbers with a simple forecast.
Post calendar — Log your posts with send date, subject, and imported open/click rates. See which topics performed and which flopped.
Sponsor pipeline — Track sponsors by status (pitched, confirmed, invoiced, paid). Log rates, deliverables, and payment history. Know what your inventory is worth.
Cohort analysis — See subscriber retention by cohort. Know how long readers stick around and what a new subscriber is worth over 12 months.
Why not just use Substack’s built-in analytics?
Substack shows you vanity metrics. Creator shows you the business: true MRR, churn rate, sponsor ROI, content-to-revenue correlation. No API key required — just export your CSVs and import.
