About

NAVA — Tab Intelligence System

NAVA is a premium, privacy-first browser intelligence layer built for people who care about where their attention goes. It transforms your Chrome tabs from a chaotic pile into a structured, mindful workspace without ever sending your data anywhere.

Tab Tracking and Time Intelligence

NAVA silently tracks how long you spend on every tab in real time. The moment you switch tabs, it starts the clock on the new one and stops it on the old one. When your browser window loses focus, tracking pauses so you are never penalized for stepping away from your computer. All time data accumulates across your session and persists in local storage, surviving popup closes and browser restarts.

Every tracked tab stores its title, URL, domain, total time spent, first-seen timestamp, and last-active timestamp. This forms the foundation for everything else NAVA does.

Popup Dashboard

Click the NAVA icon in your toolbar and get an instant overview of your browsing session. A four-stat bar at the top shows open tab count, total focus time, number of unique domains, and number of custom groups. Below that, your top three most time-intensive tabs are ranked with animated progress bars, favicons, domain labels, and exact time spent. The number one tab gets a distinctive gradient accent to set it apart.

A groups preview shows all your custom tab groups with color-coded indicators and tab counts. A recently closed section keeps the last twenty tabs you closed available for one-click restore at any time.

Full Dashboard

Clicking the Dashboard button opens a full workspace window where NAVA does its most powerful work. A sidebar on the left holds your navigation options, a live session stats footer, and your complete list of custom groups. The main panel to the right displays all open tabs as a responsive card grid, with each card showing the favicon, title, domain, time spent, an animated progress bar, and a color tag if the tab belongs to a group.

A search bar filters the entire grid in real time against tab titles and domains. A sort button cycles through time-based, alphabetical, and most-recent ordering. A domain view groups tabs under collapsible headers sorted by total time spent. The dashboard reacts to live browser events, so opening, closing, or navigating a tab updates the grid immediately without any manual refresh.

Custom Tab Groups

Groups are created from the dashboard sidebar using a modal that accepts a name and one of ten accent colors. To assign a tab to a group, drag its card and drop it onto the group name in the sidebar. The assignment is stored immediately and the group count updates in place. A visual cue appears at the bottom of the screen during any drag to guide the drop. Tabs display their group membership as a small color label inside their card, and closing a tab automatically removes it from any group it belonged to so your groups stay accurate.

Focus Mode

A Focus session is started from the popup using a duration picker with quick options of fifteen, twenty-five, forty-five minutes, or one hour, plus a custom input accepting any value up to eight hours.

While a Focus session is active, a circular countdown timer fills down in real time showing minutes and seconds remaining. A badge appears in the popup header indicating the current mode. The ambient color palette shifts to indigo to signal that a focused state is in effect. The session panel shows the start time, end time, and which groups are designated as allowed. Tabs not belonging to allowed groups are visually dimmed and made non-interactive in the popup, reducing the pull of off-task browsing. Allowed groups are highlighted with a glowing border in the groups list. The footer message changes to reflect that a session is active.

The session is stored in local storage and backed by a Chrome alarm. This means the timer survives popup closes, background script hibernation, and browser restarts. When the duration expires, the alarm fires and the session ends automatically. An early end button is always available.

Relax Mode

Relax Mode is the intentional counterpart to Focus Mode. It signals a recovery period where no productivity pressure is applied. The same duration picker is used to set the length of the session.

While a Relax session is active, the countdown timer runs in a calming green color scheme. The top tabs section with its rankings and time comparisons is hidden entirely. In its place, a soft summary panel appears showing total browsing time, open tab count, and the most visited domain, presented as neutral observations rather than performance metrics. The footer message and overall tone of the interface shift to reflect that rest is the intention. Like Focus Mode, Relax sessions persist and auto-expire reliably through Chrome alarms.

Privacy and Architecture

NAVA operates entirely offline. It makes zero network requests, has no backend, no account system, no telemetry, and no analytics. No data ever leaves your machine. All information lives in Chrome local storage across four keys covering tab time data, custom groups, recently closed history, and active session state.

The background service worker is fully event-driven, using Chrome tab and window events to drive all tracking logic. A one-second tick accumulates time only on the active, focused tab. Session timers use Chrome alarms rather than intervals because alarms survive service worker suspension, making them the correct and reliable tool for minute-scale timers in a Manifest V3 extension.

The permissions used are tabs for reading and managing tab state, storage for all local persistence, windows for opening the dashboard and tracking focus changes, and alarms for reliable session expiry.
