How to write a great reply
- 1Paste the original post — the more context it contains, the more relevant the replies. Long threads? Just paste the key paragraph.
- 2Pick a tone that matches your relationship to the author and the platform. Casual for friends and peers; Professional for thought leaders and industry posts.
- 3Copy the reply you like best, post it, and engage. The best replies add a perspective, ask a genuine question, or share a related insight.

Frequently Asked Questions
Is this AI reply generator free?
Yes — completely free. No account or login required. Just paste a post and generate replies instantly.
What tones can the AI reply in?
Four tones: Casual (friendly, natural), Professional (polished, respectful), Witty (clever, sharp), and Supportive (warm, encouraging). Each produces distinctly different replies.
How long can the original post be?
Up to 1,000 characters. The generated replies are always kept under 280 characters so they fit X/Twitter's character limit.
Will the replies include hashtags?
Only when genuinely necessary. The AI avoids stuffing replies with hashtags because they rarely add value to a reply and can feel spammy.
Can I use this for LinkedIn or Instagram replies too?
Yes — the tool works for any short-form social post. Paste the original text and select the tone that fits your platform.
