What is a Comment Generator?
The comment generator is a free AI tool that turns any social media post into a ready-to-paste reply that sounds like a real person typed it. Drop in what the post is about, pick the platform, choose a tone and length, and the tool returns up to five drafts — each tuned for the platform's culture and short enough to copy straight into the comment box.
Built for the way people actually engage in 2026. Most online comment writers either spit out a single bland sentence or pad every reply with the same "Great post!" opener that gets ignored. This one is purpose-built: one platform field shifts the voice between Instagram warmth, LinkedIn substance, TikTok punchiness, and X brevity; eight tones cover everything from supportive friend-energy to a sharp witty one-liner; and a length toggle keeps replies native to the feed they are going into. No account, no daily cap, no scheduling lock-in — drop in, copy the variant that lands, and paste.
Key Features
Replies That Sound Human, Not Bot-Drafted
The model is prompted as a real social media engagement writer, with a banned-phrase list of every overused opener ("Great post," "Love this," "Amazing!") so every draft starts somewhere a real person would actually start.
Eight Platforms, Each With Its Own Voice
Pick Instagram, YouTube, LinkedIn, TikTok, X, Facebook, Threads, or generic. The voice, length, emoji density, and lingo all shift — a TikTok reply never sounds like a LinkedIn post and vice versa.
Eight Tones That Actually Feel Different
Supportive, funny, compliment, curious question, thoughtful take, professional, witty, or playful. Each tone is tuned with its own style instructions so a witty reply lands sharp and a supportive one stays warm without slipping into saccharine.
Length Control From One-Liner to Substantive Take
Short for a tight one-liner under 80 characters, medium for the typical one-to-two-sentence reply, long for a three-to-five-sentence take that can spark a thread on LinkedIn or YouTube.
Up to Five Drafts in One Click, Each From a Different Angle
Slide the count to five and the tool writes each variant from a different hook or angle — so you almost always get at least one keeper instead of five rephrasings of the same idea.
Perfect for creators replying to their own audience without burning a whole evening, social media managers running multi-brand accounts, indie founders building community in public, and anyone trying to support a friend's post without typing "Love this!" for the fifteenth time.
How to Use the Comment Generator
Three quick choices, one click, up to five usable drafts — under twenty seconds end to end
