## What is AI Sentinel?

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.

AI Sentinel Pro is an auto-renewable subscription: $2.99/month or $19.99/year, each with a 7-day free trial. Payment is charged to your Apple ID at confirmation of purchase. The subscription auto-renews unless turned off at least 24 hours before the current period ends; your account is charged for renewal within 24 hours before the period ends. Manage or cancel anytime in your App Store account settings.

## Version history (last 2 releases)

### 1.0.1 — 2026-08-10

Everything in this update, since 1.0:

- Fluid card-to-detail transition: swipe up to peek, keep going to open; pull down from the top to return.
- Karaoke-style transcript for the audio review: the current sentence highlights word by word, stays centred, and re-opens where you left off. Tap any sentence to jump there.
- Chapter list: jump straight to any section of the briefing.
- Review history is now a single timeline in date order, so the newest edition is always on top.
- Offline downloads now have a home in Settings: see what's stored, how much space it uses, and remove any of it.
- When a briefing finishes, the player closes cleanly instead of lingering.
- Sharing: share cards now carry a tappable link.
- Switching content language now switches the audio too.
- Full Simplified Chinese throughout, plus stability fixes to content loading, subscription state and keyword sync.

### 1.0 — 2026-07-18
