// common questions

How is this different from searching Substack?

Substack shows you what's on Substack. NicheIndex shows competition density, growth trajectories, segment breakdowns, and publishing behavior across the full market. Different question, different answer.

Can I try before paying?

The free tier is a real product, not a trial. Browse the index, follow niches, get a niche scorecard. When you want the analysis layer, that's Creator.

How current is the data?

The census refreshes daily. Behavioral signals refresh twice a week. Every metric carries a timestamp so you know exactly how fresh it is.

Why annual pricing?

Markets move. New newsletters enter. Competitors grow. A one-time snapshot is a directory. An annual subscription is a market intelligence tool. The value is in the ongoing picture, not the single moment.

Does the index cover local and regional newsletters?

Yes. The index includes local and regional publications. Sponsor Intelligence tier includes priority data requests. If a market you care about isn't indexed, we'll add it.

Is my data shared with anyone?

No. Your account, watchlists, and exports are yours.

The market is moving whether you're watching it or not.
