Promptify: Your AI usage, quantified.

Promptify is a 100% local, privacy-first browser extension for Chrome and Firefox that automatically tracks your active time across popular AI conversational platforms (ChatGPT, Claude, Gemini, Perplexity, Qwen, DeepSeek, Kimi, Copilot, and Grok).

There are no servers, no telemetry, and no accounts required. All data is stored in your browser's local IndexedDB, keeping your usage data entirely in your hands.

   • Toggle the Developer mode switch in the top right corner of the Extensions page.

4. Load Unpacked:

   • Click the Load unpacked button in the top left.

How It Works

Promptify uses a highly optimized state machine running entirely in the browser:

Component	Responsibility
Content Scripts	Injected only on supported AI sites. Detects when the user is actively interacting (mouse moves, clicks, typing) or if the tab is visible. Sends heartbeat events.
Service Worker	Runs in the background (src/background.js, src/platforms.js, src/db.js). Maintains the state of the active session. If it receives heartbeats, it accumulates time. If the tab is closed, hidden, or idle, it finalizes the session and saves it.
IndexedDB	The local database (src/db.js) where completed sessions are permanently stored.
Analytics Dashboard	A fully local, Neo-Brutalist dashboard (pages/dashboard/dashboard.html) to visualize daily, weekly, and monthly usage.

Tracking Rules

A session is considered active only when:

1. The AI website is the active browser tab
2. The browser window is focused
3. The page is visible
4. The user has interacted recently (mouse, keyboard, click, scroll)

Inactivity timeout: 5 minutes of no interaction ends the session.

This means idle time is never counted, even if you leave an AI tab open in the background for hours.
