## Short Description

Lumno gives browser power users an Arc-inspired command bar without requiring them to switch browsers. It is useful for people moving from Arc to Dia or Chrome, and for anyone who wants one place to search open tabs, bookmarks, history, frequently visited pages, and supported site engines.

## Target Users

- Researchers and writers who need to recover context across search results, docs, notes, bookmarks, and browser history.
- Developers and designers who frequently jump between GitHub, documentation, product consoles, design references, and debugging pages.
- Students and knowledge workers who want a clean new tab and faster access to saved or recently visited pages.
- People migrating from Arc who want a familiar command bar workflow inside Dia, Chrome, Edge, or another Chromium browser.

## Differentiation

Lumno is not a full browser replacement. It is a browser extension that focuses on high-frequency lookup and switching workflows: opening a command bar from any page, finding existing browser context, sending queries into supported sites, and keeping a minimalist new tab.
