Show HN: I built an AI that finds Substack newsletters you'll read
mynewsletterguide.comI 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
