Dev builds AI newsletter pipeline with Jev, Haiku and Sonnet that clusters news into narratives
runwithdata · reddit · 2026-11-13
A developer shares his automated AI-news pipeline: TypeSafe's Jev filters stories for under a cent each, Claude Haiku summarizes them, embeddings cluster stories into named narratives, Sonnet writes the daily issue, and Jev fact-checks every text against sources.
The narrative layer proved most useful — revealing which developments connect and which trends are gaining momentum across days and weeks.
16,000 lines of TypeScript, 370 tests, built with Claude Code on Cloudflare Workers.
