Comment Reply Drafter

WHAT IT DOES

Comment Reply Drafter reads the current page content — posts, comment threads, or conversation history — extracts the text of the most recent or selected comment, and sends it to the AI to draft a contextually appropriate reply. You can configure the reply tone (professional, friendly, casual, or concise) and length (short, medium, or long), and choose whether to include key points from the conversation. The draft is presented for review before you copy it to your clipboard or paste it directly into the reply box.

WHERE IT RUNS

This userscript runs inside major social media and discussion platforms including Facebook, X (Twitter), Reddit, LinkedIn, and YouTube in your browser, powered by the free BotGentz extension. It operates entirely on the page you are viewing — it reads the current comment or post and sends it to the AI backend for drafting. All AI processing happens remotely, but your conversation data is only sent for the purpose of generating the reply.

HOW TO USE

Install the BotGentz extension and ensure you have an active subscription, then install this userscript from the BotGentz catalogue. Navigate to any supported platform — Facebook, X, Reddit, LinkedIn, or YouTube. Open a post or comment thread you want to reply to. The tool will automatically extract the text of the most relevant comment or post. Configure your reply settings — select a tone (professional, friendly, casual, or concise) and length (short, medium, or long). Toggle "Include key points" to incorporate conversation context, or "Auto-copy" to automatically copy drafts to your clipboard. Click "Draft Reply" to generate a reply. Review the draft, click "Copy Reply" to copy it, or "Regenerate" to try a different version.

HOW IT WORKS UNDER THE HOOD

The script first attempts to extract the current comment using WebMCP if available — the new W3C proposal for structured browser tools — which allows direct, typed access to page data without DOM scraping. If WebMCP is not available, the script falls back to a multi-strategy DOM extraction approach, scanning for comment content using platform-specific selectors (.comment-content, .tweet-text, .reddit-comment-content, etc.), post body selectors, and finally selected text or page content. The extracted text is then sent to the AI backend via a secure API call with your subscription key. The AI processes the input with a system prompt that instructs it to generate a reply with the specified tone and length, caps the output at 1,024 tokens, and avoids preambles or meta-commentary. The response is presented in the panel for review.

THE PANEL

The tool runs in the BotGentz panel, a draggable floating interface that stays on top of the page. You can drag the panel by its header, collapse it to a small bubble, and resize it. The panel remembers its position per site, so it stays where you left it when you return to the platform. Press Escape to close the panel when you are done. The panel includes settings for tone and length, a display area showing the original comment, a draft display area, and action buttons for drafting, copying, regenerating, and saving settings.

PLEASE NOTE

This tool requires the free BotGentz extension and an active subscription to the AI service. AI-generated replies should be reviewed before use — they are drafts, not final responses. The tool works only on the current page and extracts the most relevant comment or post automatically. Social media platforms frequently update their interfaces — if the tool stops working, check for an updated version or report the issue. Your conversation data is only sent to the AI backend for the purpose of generating the reply; no data is stored permanently.
