Reddit Comment Drafter

WHAT IT DOES

Reddit Comment Drafter reads the current Reddit post, its title, and the comment thread from the page, extracts the post content, title, and existing comments, and sends them to the AI to draft a contextually appropriate comment. You can configure the comment tone — helpful, informative, friendly, professional, or concise — and choose the comment length (short, medium, or long). You can also choose whether to include the full thread context in the drafting, whether to follow Reddit etiquette, and enable auto-copy to automatically copy drafts to your clipboard. The draft is presented in the panel for review before you copy it to your clipboard or paste it directly into the Reddit reply input field.

WHERE IT RUNS

This userscript runs inside Reddit (reddit.com/r/*) in your browser, powered by the free BotGentz extension. It operates entirely on the page you are viewing — it reads the Reddit post and comments from the page and sends them to the AI backend for drafting. All AI processing happens remotely, but your Reddit post data is only sent for the purpose of generating the comment.

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 Reddit post thread. Open the tool panel, select your desired tone and comment length, and toggle the options to include thread context, follow Reddit etiquette, or auto-copy. Click "Draft Comment" to generate a comment. The tool will display the extracted post, title, and comments, along with the drafted comment. Review the draft, then click "Copy Comment" to copy it to your clipboard, or "Regenerate" to try a different version.

HOW IT WORKS UNDER THE HOOD

The script first attempts to extract the Reddit thread using WebMCP if available — the new W3C proposal for structured browser tools — which allows direct, typed access to Reddit thread data without DOM scraping. If WebMCP is not available, the script falls back to a multi-strategy DOM extraction approach. It extracts the subreddit name for context, the post title using selectors like h1, [data-testid="post-title"], and .PostTitle, the post content from [data-testid="post-content"] or .PostContent, and comments from [data-testid="comment"] or .Comment. Author names are extracted from .author or [data-testid="author"] to preserve conversational context. The extracted thread 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 comment with the specified tone and length, optionally considering thread context and Reddit etiquette, and caps the output at 1,024 tokens. 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 Reddit. Press Escape to close the panel when you are done. The panel includes settings for tone, length, thread context inclusion, Reddit etiquette, and auto-copy, a display area showing the extracted thread and the drafted comment, 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 comments should be reviewed before use — they are drafts, not final responses. The tool works only on the current page and may not detect all Reddit posts depending on platform structure. Reddit frequently updates its interface — if the tool stops working, check for an updated version or report the issue. Your Reddit post data is only sent to the AI backend for the purpose of generating the comment; no data is stored permanently. Always review AI-generated comments for accuracy and relevance before posting.
