Hey Hunters — I'm the maker. I built DeepSignal because the existing AI feeds either drown me in noise (Twitter), gatekeep behind a paywall (most newsletters), or wait 24 hours to ship (everything else). The site does three things differently: 1. Every article gets a 0–100 Signal Score using a documented formula (source authority 30 + technical impact 25 + business impact 15 + novelty 30, half-life 1.5 days). The score is published on every card so you can argue with it. 2. Featured caps any single source at 2 slots — no source-flooding. 3. Daily brief picks YOUR local-yesterday window, not UTC. Bilingual en/zh set per subscription. Email/Slack/Feishu, your local 8am. 800+ articles indexed. Free, no signup needed to read. Stack is Next.js 15 + Supabase + Vercel cron + OpenAI gpt-4o-mini. Things I'd love feedback on: - Sources I'm missing (especially APAC + EU labs) - Whether the score weighting feels right - Daily brief format (length, frequency, vertical ordering) Thanks for hunting!
