Social Post Rewriter for Different Platforms

WHAT IT DOES

Social Post Rewriter for Different Platforms reads the drafted post text from the page input field and sends it to the AI to rewrite it for a different social media platform. You can choose from five target platforms — Facebook, X (Twitter), LinkedIn, Reddit, or Instagram — and the tool applies platform-specific tone, style, and formatting to ensure your post fits the expectations of each audience. You can also select a tone modifier (professional, friendly, or concise), toggle whether to preserve the original length, and choose whether to include hashtags. The rewritten version is presented in the panel for review, and you can copy it or regenerate a new version.

WHERE IT RUNS

This userscript runs inside major social media and professional platforms including Facebook, X, LinkedIn, Reddit, and Instagram in your browser, powered by the free BotGentz extension. It operates entirely on the page you are viewing — it reads the drafted post from the page and sends it to the AI backend for rewriting. All AI processing happens remotely, but your post text is only sent for the purpose of rewriting it for a different platform.

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, LinkedIn, Reddit, or Instagram — and type a draft post in the input field. Open the tool panel, select your target platform from the dropdown (Facebook, X, LinkedIn, Reddit, or Instagram), choose a tone modifier, and toggle the options to preserve length or include hashtags. Click "Rewrite Post" to generate the platform-adapted version. Review the rewritten post in the panel, then click "Copy Rewritten" to copy it to your clipboard. You can also use the manual input field to paste text that isn't in a standard post input.

HOW IT WORKS UNDER THE HOOD

The script first attempts to extract the drafted post using WebMCP if available — the new W3C proposal for structured browser tools — which allows direct, typed access to the post input without DOM scraping. If WebMCP is not available, the script falls back to a multi-strategy DOM extraction approach, scanning for post input fields using selectors like [data-testid="post-input"], textarea[placeholder*="Write"], and [contenteditable="true"]. 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 rewrite the post for the specified platform using platform-specific style guides — casual for Facebook, concise for X, professional for LinkedIn, authentic for Reddit, and visual-focused for Instagram — and applies the selected tone modifier, length preference, and hashtag inclusion. 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 target platform, tone, length preservation, and hashtag inclusion, a display area showing the rewritten post, and action buttons for rewriting, copying, regenerating, and saving settings.

PLEASE NOTE

This tool requires the free BotGentz extension and an active subscription to the AI service. AI-generated rewrites should be reviewed before use — they are drafts, not final responses. The tool works only on the current page and may not detect all post input fields depending on platform updates. Social media platforms frequently update their interfaces — if the tool stops working, check for an updated version or report the issue. Your post text is only sent to the AI backend for the purpose of rewriting it for a different platform; no data is stored permanently. The manual input field can be used as a fallback for unsupported platforms or inputs.
