Measurably
Browser developer preview

Put the prompt coach where you already write.

Version 0.7.0 brings six-dimension scoring, recommendations, and Enhance, Polish, Formalize, Shorten, and Structure actions into supported AI websites. Baseline coaching stays in the active tab.

Install it in four deliberate steps.

This is a direct developer-preview package, not a Chrome Web Store listing. Chromium browsers require Developer mode for unpacked extensions.

  1. 01

    Download and unzip

    Keep the measurably-extension folder intact after extracting the archive.

  2. 02

    Open extensions

    Use chrome://extensions in Chrome or Brave, edge://extensions in Edge, or your Chromium browser’s extensions page.

  3. 03

    Enable Developer mode

    Choose Load unpacked and select the extracted measurably-extension folder.

  4. 04

    Coach a prompt

    Type at least ten characters in a supported AI prompt field and open the Measurably badge.

One product, three release states.

A downloadable archive is evidence for the browser preview only. It does not turn unsigned desktop source into a released installer.

Download available

Chromium browsers

Local scoring and five deterministic prompt actions on supported AI websites.

Source setup

Terminal agents

Codex and Claude Code hooks are available from source on macOS and Linux; Windows setup is not released.

Validation

Desktop app

The owned editor builds from source. Signed and physically accepted installers are not available yet.

What stays local

  • Baseline scoring and prompt transformations
  • Raw prompt text used transiently in the active tab
  • Apply, copy, discard, and send remain user actions

Preview boundaries

Account pairing and cloud sync are paused. Third-party sites can change their prompt fields without notice. This package is checksummed but is not store-reviewed or publisher-signed.
