Built for publishers like you

I've thought about creating a curated digest of interesting articles for my readers.

But manually reading through 10, 20, or more newsletters to surface content is very time-consuming.

I built StackDigest to make creating curated collections of newsletters and building curated roundups of interesting content faster and easier.

Common questions from publishers

StackDigest helps newsletter publishers create curated digests of content from across their niche or industry.

It's perfect for creating "This week in [your topic]" style content.

While the reader version helps individuals manage their personal newsletter subscriptions, the publisher version is designed for content creators who want to curate digests for their audience. Publishers will be able to customize the digest format for their brand and potentially white-label the output for seamless integration with their existing newsletter.

Publisher features are currently free during the beta period. I'm working closely with early publisher partners to refine the features and understand different use cases. Beta publishers will receive special pricing when we launch paid tiers.
