AI Sentinel: Frontier Daily

AI Sentinel

The AI frontier in 5–8 minutes, every day. An LLM pipeline reads the day's research and releases, ranks them on four axes, and this is the top of the list — with the reasoning.

Every claim you hear is source-checked before publishing — errors are fixed, then the full review is re-audited until it passes clean.

The iOS app is the rest of it, and the content is free: the full ranked feed that learns what you care about, the complete daily review with every source, and your own research queue for what you want to keep. Pro adds keyword alerts the moment your topics move, a daily voice recap, and the 30-day archive. https://getaisentinel.com
