CommentGPT uses AI and image analysis to create context-aware comments for social media. Works on all major platforms. Free to use. Never stare at a blank comment box again. CommentGPT reads the post you're viewing and drafts a thoughtful, context-aware comment in seconds — right inside LinkedIn, X (Twitter), Facebook, and Instagram. You review, edit, and post. Nothing is ever posted automatically — you're always in control.
Whether you're replying to a colleague on LinkedIn, joining a conversation on X, or commenting on a friend's post, CommentGPT helps you say something relevant and genuine without the blank-page pause.
WHAT YOU GET ✔️ Context-aware AI comments based on the actual post (text and images) ✔️ 11 comment styles — supportive, funny, thoughtful, congratulatory, constructive, and more ✔️ Length and tone controls — short or detailed, professional, witty, empathetic, casual, or expert ✔️ 100+ languages, including right-to-left (Hebrew, Arabic), with automatic detection ✔️ Works on LinkedIn, X, Facebook, and Instagram ✔️ No sign-up required — install and use ✔️ Text-to-speech to hear a draft read aloud ✔️ Fast and lightweight (~130 KB), private and secure
FREE AND PREMIUM CommentGPT is free — up to 50 AI comments a day. Upgrade to Premium for unlimited comments, image analysis (the AI reads the photos in a post, not just the text, for more relevant drafts), and priority speed when demand is high.
HOW IT WORKS 1. Open a post on LinkedIn, X, Facebook, or Instagram. 2. Click the CommentGPT button near the comment box. 3. Pick a style, length, and language — then review, edit, and post your comment.
You stay in control at every step. CommentGPT only ever drafts a suggestion; you decide what, if anything, gets posted.
