Email Reply Length Shortener

WHAT IT DOES

Email Reply Length Shortener reads your drafted reply or selected text and rewrites it to be significantly shorter while preserving all key information, intent, and tone. Choose your target brevity: Slightly shorter (tighten phrasing), Much shorter (remove redundancy), or Maximally concise (minimal essential words). Toggle tone preservation to maintain your original style or make it more direct. Toggle key details preservation to keep all factual information. The shortened version appears instantly—review it, then replace your draft or copy it to your clipboard. Perfect for making emails more impactful, cutting fluff from replies, and saving your readers' time.

WHERE IT RUNS

Any webpage with text fields, selected text, or draft content—Gmail, Outlook, Yahoo Mail, LinkedIn messages, Slack, and more. Works with standard textareas, input fields, and contenteditable elements. If you can type it or select it, this tool can shorten it.

HOW TO USE

Install the script and navigate to your draft or any text. Select the text you want to shorten, or click into the field containing your draft. Click "Get Text" in the panel—the tool detects your selected text or field content. Choose your brevity level and toggle tone and details preservation. Click "Get Text" to process—the shortened version appears in the panel. Review it, make manual edits if needed, then click "Replace" to update your field or "Copy" to paste it elsewhere. Settings persist per site and globally—the tool remembers your brevity, tone, and details preferences. Keyboard shortcuts: Ctrl+Shift+S to shorten, Ctrl+Shift+R to regenerate, Ctrl+Shift+I to replace the current field with the shortened text.

TECHNICAL MECHANISM

The script detects input sources in priority order: selected text via window.getSelection(), active field via document.activeElement (filtering out password, hidden, and file inputs), or any textarea on the page. The detected text is sent to the BotGentz AI backend via GM_xmlhttpRequest with a structured prompt that includes the target brevity level (slightly/much/maximally), tone preservation toggle, and details preservation toggle. Brevity mapping guides the AI: slightly = tighten phrasing, much = remove redundancy, maximally = minimal essential words. The prompt instructs the model to remove unnecessary words and fluff while preserving key information, intent, and meaning. The response is displayed in a textarea, and replacement uses native value setting with both "input" and "change" events dispatched to ensure React and Vue applications update correctly. Settings persist via GM_setValue with per-site overrides for brevity, tone, and details preferences.

THE PANEL

The tool runs inside BGPanel, a lightweight UI system built into the BotGentz extension. Drag the panel by its header to reposition it anywhere on screen—it snaps to edges and remembers its position per site. Click the header to collapse the panel into a small bubble; click again to expand. Resize the panel by dragging its bottom-right corner. Press Escape at any time to close the panel. The panel stays out of your way but is always accessible via the extension's toolbar.

PLEASE NOTE

Requires the free BotGentz browser extension and an active monthly subscription—the AI backend uses credits for each generation. One generation per click; regenerate counts as a new generation. The script reads only visible text fields and selected content—it cannot access iframes or shadow DOM. AI-generated shortened text is a suggestion—always review and edit before sending. No text content is stored or shared beyond the API request; all processing is ephemeral. The tool's brevity level guides the AI's output length but actual results may vary—review the shortened text before use. Sites change over time, but this script relies on standard DOM APIs, not site-specific selectors, so it remains robust across most pages.
