Hi, I'm Karen Spinner
I built StackDigest because I needed it to exist
Why I built StackDigest
Two months into joining Substack, I had 200+ newsletter subscriptions and zero time to read them. Every notification was something I genuinely wanted to read, but my inbox had become a graveyard of good intentions.
After sharing my frustration in a Substack Note, more than 100 readers responded with the same problem. That weekend, I built a Python script to automatically collect, score, and summarize my newsletters. It worked so well that I turned it into StackDigest.
How it works
StackDigest is built specifically for newsletter readers who value quality content but struggle with volume. Unlike generic email aggregators, it understands that newsletters are relationships with writers you trust and ideas you're tracking over time.
The tool:
- Pulls articles from all your newsletter subscriptions
- Scores content based on engagement and depth
- Creates AI summaries that preserve author insights
- Organizes everything into clean, readable digests
- Maintains history so you never lose important content
By the numbers
Built and tested with real users

Built in public
I'm building StackDigest in public with feedback from beta testers who use it daily. This isn't venture-backed software optimizing for engagement metrics. It's a tool built by a reader who needed it to exist.
Every feature comes from real frustration with information overload. Every improvement comes from user feedback.
