CommentGPT: AI Comment & Reply Assistant

AI comment & reply generator for LinkedIn, X, Facebook & Instagram. Reads the post, drafts a fitting reply. You edit & post. Free.

Never stare at a blank comment box again. CommentGPT is an AI comment and reply generator that works right inside LinkedIn, X (Twitter), Facebook, and Instagram. It reads the post you're viewing, or the comment you're replying to, and drafts a thoughtful, context-aware comment in seconds. You review, edit, and post. Nothing is ever posted automatically — you're always in control. Use it as a LinkedIn comment generator for thoughtful professional replies, to join a thread on X, or to find the right words for a friend's news on Facebook or Instagram. It helps you say something relevant and genuine, without the blank-page pause. WHAT YOU GET ✔️ Context-aware AI comments based on the actual post ✔️ Replies to a specific comment, not just the post — it reads the comment you're answering ✔️ One-click Quick Comment — the ↻ button drafts a fresh comment with your last settings, straight into the comment box ✔️ 12 comment styles — positive, funny, informative, supportive, congratulatory, a thoughtful question, respectful disagreement, and more ✔️ Length and tone controls — short to detailed; professional, witty, empathetic, casual, or expert ✔️ Brand Voice — describe who you are and how you like to sound once, and every draft follows it ✔️ 100+ languages, including right-to-left (Hebrew, Arabic), with automatic detection ✔️ Text-to-speech to hear a draft read aloud ✔️ No sign-up required — install and use FREE AND PREMIUM CommentGPT is free — up to 50 AI comments a day. Premium adds 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 by the comment box, or by the reply box under any comment. 3. Pick a style, length, and language, then review, edit, and post. Next time, one click on ↻ drafts with the same settings. You stay in control at every step. CommentGPT only ever drafts a suggestion; you decide what, if anything, gets posted. FAQ Does CommentGPT post anything automatically? No. It only drafts suggestions. You review, edit, and post yourself. Can it reply to a comment, not just the post? Yes. Use the button in a comment's reply box and the draft answers that comment, with the post as context. Which sites does it work on? LinkedIn, X (formerly Twitter), Facebook, and Instagram. Is it free? Yes — up to 50 comments a day free. Premium unlocks unlimited comments, image analysis, and priority speed. Is my data private? CommentGPT only reads the post you're actively commenting on, to draft your reply.
