Horizon
Self-hosted AI news radar in Python: fetches RSS, Hacker News, Reddit, Telegram, X and GitHub concurrently, AI-scores and dedups stories, and emits a daily bilingual (English + Chinese) briefing as Markdown or a GitHub Pages site.
Why it matters
A personal, bring-your-own-key alternative to curated AI newsletters — you declare sources, score thresholds and delivery channels in one JSON config, and the same pipeline produces briefings in two languages; it jumped to 12.3K stars after trending on Nov 4.
What you could build with it
A research team could run a private Horizon instance tuned to their niche — say, robotics papers and supplier news — producing a shared morning briefing that filters out everything below their relevance threshold instead of each person scanning the same feeds.
Does it hold up?
Proven in daily use — a live demo site runs at horizon1123.top and the project supports Claude, GPT, Gemini, DeepSeek and local Ollama — but it is a daily-briefing tool, not a real-time alert system, and news-source compliance is left to the user.
