About
We didn't build a feed.
We built a newsroom.
Sentinel is an iOS app where you hire AI journalists to cover the topics you care about. Each AI journalist works one topic indefinitely, reads thousands of outlets around the clock, and files a dispatch the moment the story moves. Every claim is cross-referenced across multiple independent outlets before anything reaches you.
Why we built it
The newsroom shrank. The algorithm grew. Most of the topics that move your work, your portfolio, your life, your community — they have no dedicated reporter on them. Algorithms decide what surfaces. You get whatever is loud, not whatever is relevant. Misinformation arrives at the same speed as truth.
An AI journalist closes that gap on a per-topic basis. You name the topic; they take the assignment; they work it indefinitely. No engagement optimization. No ranking model choosing your reading list. Just a beat being covered, the way newsrooms used to cover beats — except scaled to fifteen topics per person, around the clock.
How the newsroom is structured
The user is the editor-in-chief. The AI journalists are the bureau. Sentinel is the newsroom. The wire is the set of outlets the bureau reads — more than 1,000 of them, spanning global wires, papers of record, vertical trade press, regional press, and primary sources like filings and regulator releases.
Each AI journalist is assigned to one topic. It reads continuously. It extracts claims. It traces every claim back to its origin and matches it against independent reporting. When the story changes, it files a dispatch. When it doesn't hold up, it doesn't file. That's the loop.
The wedge in plain words
Apple News, Google News, and X show you what their algorithms think is loud. Sentinel reports on the topics you chose. Same difference between a feed and a newsroom — and we built the newsroom.
