Measurably
Browser developer preview

Put the prompt coach where you already write.

Version 0.8.0 brings six-dimension scoring, five prompt actions, and an explicit next-prompt preview into supported AI websites. It uses the current draft and latest visible assistant response or, from an empty composer, the latest visible preceding user/assistant pair. It never auto-submits.

Terminal and MCP source preview

Give Codex and Claude a local prompt coach.

Version 0.3.0 packages Score, Enhance, Polish, Formalize, Shorten, Structure, and next-prompt suggestions into a bounded local MCP server. It does not read chats on its own or persist tool arguments.

Verify the checksum before installation. Install never overwrites an existing named entry. Configuration proves setup only: restart the host, then invoke a tool to prove execution. macOS is locally accepted; Windows and Linux remain native-validation targets. In cmux, Codex or Claude Code launches the same configured server—Measurably does not inspect panes or terminal processes. Guided setup does not configure Claude Desktop.

On Linux use sha256sum -c; on Windows compare Get-FileHash -Algorithm SHA256 with the downloaded sidecar. If Node or the global npm prefix changes, uninstall and reinstall the named integration so its absolute paths stay current. Remove the package with npm uninstall --global measurably-cli.

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.

Next-prompt context exists only in page and extension JavaScript memory while the preview is active. The host page itself may retain visible chat content under its own policy.

  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, open the badge, or choose Suggest next. Tab accepts only a visible preview at a safe end caret and never submits it.

One product, three release states.

The two downloadable archives prove only their browser and CLI source-preview layers. They do not turn unsigned desktop source into a released installer.

Download available

Chromium browsers

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

CLI archive available

Terminal agents

A checksummed CLI configures local MCP tools for Codex and Claude Code; macOS is locally accepted while Windows and Linux await native host acceptance.

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
  • Browser context remains transient in the active tab
  • MCP arguments stay in the local server process
  • 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. A browser page, MCP host, or model provider may separately retain content under its own policy. These packages are checksummed but are not store-reviewed or publisher-signed.
