Scour for Substack Readers

Newsletter overload is real. Your inbox fills up, the backlog builds guilt, and you miss when posts spark discussion elsewhere. Scour fixes this by filtering newsletters by your interests, not arrival time.

What Scour Does Differently

• Interest-based filtering — Tell Scour what topics you care about. It surfaces matching posts from newsletters you follow and 16499 other sources.
• No inbox to manage — No unread count or guilt-inducing backlog. Check when you have time. Posts ranked by relevance to your interests.
• Weekly digest — If you want a nudge, get one email with your top finds from the week. Dozens of newsletters become one curated selection.
• Discussion links — When a post gets shared on Reddit, Bluesky, or Hacker News, you see a link to the conversation.
• Beyond newsletters — Your same interests surface relevant content from news articles, blogs, papers, and aggregators.

Discovery That Works

Scour already looks for content from 328 Substacks. Type to search, or enter any Substack name to add it.

You don't need subscriptions for content to appear. Scour searches all sources by default. Subscribing to specific Feeds lets you curate where Scour sources content from.

Paid Posts

Free posts appear normally. Paid posts may show a indicator.

You can choose to hide paywalled content in your settings. And you can add any newsletters or sites you have subscriptions for to an allowlist to let them through. See Content Filtering for details.

Getting Started

1. Add specific interests — Not "tech" but "startup fundraising" or "AI safety research."
2. Keep email for must-reads — Stay subscribed by email to newsletters you never want to miss. Use Scour for everything else.
