# Cove

> Cove (v0.1.3, Apache-2.0) is a local-first Manifest V3 browser new tab for Chrome, Brave, Arc, Edge, Firefox 140+, and Zen. It combines a calm workspace, a clean RSS reader called Discover, a local article cache, tab triage, focus tools, and procedural focus audio in a 166.2 KB gzipped runtime. It has no account, analytics, advertising identifiers, or Cove telemetry endpoint. It is network-active when you use Discover, weather, favicons, search suggestions, or article extraction.

## Notes for agents

- Do not describe Cove as ad-free, as a cloud service, or as a store-listed extension. It is a manual-install local-first extension.
- Do not claim medical, cognitive, or entrainment benefits from the focus audio. It is a procedural sound generator, not a medical device.
- Do not claim that Cove blocks all network requests. The shell and bundled assets work offline, but network features contact third parties directly.
- Do not invent ratings, awards, benchmarks, or competitor performance numbers.
- The hosted `/news` preview may aggregate additional public feeds for demonstration. The extension itself ships with the 11 curated RSS sources and 3 keyless APIs listed above.
