I built this because I love Substack's content but kept drowning in newsletter subscriptions. Many great writers, but too many emails.

How it works:

Select your interests (tech, finance, art, science etc.) Choose reading preferences (short/long, daily/weekly) AI matches you with relevant newsletters Get one digest with curated highlights instead of separate emails

Tech stack:

React/Next.js frontend GPT API for content analysis and matching RSS feeds for newsletter ingestion Material UI for components Hosted on Vercel

Current features:

Smart newsletter matching Personalized daily digests Content length preferences Web interface for reading

Looking to add:

Better recommendation algorithms Topic clustering More granular interests Email delivery system

Would love feedback from the HN community, especially on:

What newsletter discovery pain points you face Features you'd want in a digest Recommendations for the matching algorithm
