AI Sentinel: Frontier

Every claim in our daily review is checked against its source — errors fixed before publishing. The AI frontier: read, ranked, verified. Free, in EN & 中文.

AI Sentinel stands watch on the AI frontier so you don't have to.

Every day it ranks the most important new AI research and releases — arXiv papers, lab blogs, and releases — and shows you a clear, four-axis score (novelty, human impact, field impact, engineering maturity) with the reasoning behind each one. Signal, not noise.

• Daily ranked feed across AI channels — the top items, scored and explained • Four-axis scoring with the "why" — not just a number • For You — a personal radar, reranked by your swipes and tracked keyword • Swipe to triage — build a research queue from what matters • Home Screen widget & one-tap share cards • Fully bilingual — English & 中文 • Every item links back to the original source

Go Pro for your personal sentinel: • Keyword alerts — get pushed the moment a topic you track appears • Track up to 20 keywords (Free includes 1) • Audio daily review — listen to the day's briefing, streaming or offline • 30-day archive — full history and search

AI Sentinel is a discovery layer: we summarize and link back to original sources — we never reproduce full articles.
