Overview
The Measurably Chrome extension tracks and scores your AI prompt effectiveness across supported tools. Version 0.8.0 is offered as a checksummed developer-preview ZIP that users load unpacked in a Chromium browser. It is not a browser-store release. In the current preview, baseline scoring runs on your device, raw prompt text is excluded from analytics sync and stored history, and account pairing plus remote AI features are disabled.
What the Extension Collects
When you submit a prompt on a supported AI tool, the extension computes the following locally on your device:
- AI Effectiveness Score (AES): A 0–100 composite score computed from six dimensions.
- Dimension scores: Specificity, Context Engineering, Task Decomposition, Iteration Quality, Token Efficiency, and Output Specification.
- Session metadata: Tool name (e.g. ChatGPT, Claude), estimated token count, prompt length, and timestamp.
What the Extension Does NOT Collect
- Raw prompt text as analytics or stored prompt history
- AI-generated responses as analytics or stored history. The explicit Suggest next action may read the latest visible response transiently in the page; it is not stored, logged, or sent.
- Browsing history, cookies, or activity on other websites
- Personal files, documents, or screenshots
- Typed keystroke content. A local key handler recognizes only Tab to accept a visible suggestion and Escape to dismiss it; those control keys are not recorded or sent.
How Data Is Stored
- Locally (always): Scores, sessions, and daily metrics are cached in
chrome.storage.local on your device. - Cloud sync (optional): Secure account pairing is temporarily unavailable while the legacy browser-token bridge is replaced. When pairing returns, only scores and measurement metadata—not prompt bodies—will be eligible for optional dashboard sync.
Supported Tools
The current developer preview includes integrations for these AI tool websites:
- ChatGPT (chatgpt.com, chat.openai.com)
- Claude (claude.ai)
- Google Gemini (gemini.google.com)
- Grok (grok.x.ai, x.com/i/grok)
- DeepSeek (chat.deepseek.com)
- Perplexity (perplexity.ai)
- GitHub Copilot (github.com/copilot)
- Microsoft Copilot (copilot.microsoft.com)
- OpenAI Codex (codex.openai.com)
You may also add a custom HTTPS tool. The extension requests host access for that site only after your explicit browser permission; you can revoke it from Chrome at any time.
Permissions Used
storage — Cache scores and session data locally on your device.alarms — Schedule local background maintenance. Cloud sync is disabled while secure account pairing is rebuilt.- Host permissions: Includes the built-in tool domains above. Optional access to a custom HTTPS site is requested only when you add that site.
Remote AI Features
Account pairing and remote AI improvement are disabled in the current browser developer preview while secure, device-bound pairing is rebuilt. Automatic baseline scoring remains local and does not call a model provider.
Third-Party Data Sharing
We do not sell or rent your data. The current browser source candidate does not sync or send prompt bodies to an AI provider. The web product's separately invoked AI features are governed by the main Measurably Privacy Policy.
Your Rights
- Local source-candidate use: Once installed for evaluation, baseline scores can be computed and displayed locally without signing in. A verified public browser package is not yet available.
- Local use without an account: Account authentication and cloud sync are disabled in the current developer preview. Local derived measurements remain on your device.
- Request data deletion: Email support@ashlr.ai to delete all server-side data. Local data can be cleared by removing the extension.
