Atheon Helix Browser Extension

Atheon Helix is a browser extension that helps you observe, measure, understand and optimize your evolving relationship with AI across web-based platforms (ChatGPT, Claude, Gemini, AI Studio).

It operates using an isolated world bridge and local storage queuing to capture full prompt/response telemetry, token usage, and tool execution latency without relying on proxy servers or manual SDK instrumentation.

You can install Helix directly from the Chrome Web Store or sideload it manually from the latest GitHub Release.

Prerequisites

1. Install the Extension

Installing from the Web Store ensures you receive automatic updates as new parsers and platform integrations are added.

  1. Navigate to the Atheon Helix extension page on the Chrome Web Store.
  2. Click Add to Chrome.
  3. Confirm the installation when prompted.
  4. Click the puzzle piece icon (Extensions) in your browser toolbar and pin Helix for easy access.

If you want the latest parsers or require immediate access to unreleased features, you can sideload the extension directly.

  1. Download the latest chrome-extension.zip from the GitHub Releases page.
  2. Extract the archive into a permanent directory on your machine.
  3. Open a new tab and navigate to chrome://extensions/.
  4. Toggle Developer mode on in the top-right corner.
  5. Click Load unpacked in the top-left corner.
  6. Select the extracted folder called atheon-helix.
  7. Pin the extension to your toolbar.

Note: When using a manually unpacked extension, Chrome may occasionally display a prompt reminding you that the extension is running in Developer Mode. This is expected behavior.

2. Configuration

Helix requires your Atheon project API key to route telemetry to your specific Atheon Gateway project.

  1. Click the pinned Atheon Helix icon in your browser toolbar to open the extension popup.
  2. Enter your Dev Atheon API Key (arc_...) that you got from the Project Settings from Atheon Gateway.
  3. Ensure the Tracking Enabled toggle is switched to the ON position.
  4. Click Save Configuration.

You are all set. Now whenever you are on one of the supported platforms, Helix will automatically capture and route telemetry to your Atheon Gateway Project Dashboard.

How It Works

Helix uses a multi-layered architecture to bypass UI volatility and securely extract telemetry at the network layer.

The Interception Pipeline

  1. MAIN World Interceptor (intercept.ts): Injected directly into the host page context. It overrides native fetch and XMLHttpRequest interfaces, safely teeing network streams to capture complete JSON payloads and Server-Sent Events (SSE) without disrupting the host application.
  2. Secure Bridge: The interceptor transfers raw payloads to the extension's isolated world via a verified MessageChannel port, preventing host-page scripts from eavesdropping on the telemetry.
  3. ISOLATED World Parsers (content.ts): Identifies the target endpoint and applies the corresponding provider parser (e.g., Anthropic, OpenAI, Google). The parser normalizes the raw payload into a standard Atheon Interaction object.
  4. Local Storage Queue: Parsed interactions are written directly to chrome.storage.local.
  5. Background Consumer (background.ts): The service worker listens for storage changes, acts as a queue consumer with exponential backoff, and safely transmits the standardized telemetry to your Atheon Gateway Project.
