AI Commenter

Highlight text on Twitter, Instagram, or YouTube — generate a skill-tuned AI comment and paste it in one click.

AI Commenter turns any post into a reply worth posting. Replying well takes time. You read the post, think of an angle, second-guess the wording, and half the time you close the tab without saying anything. AI Commenter collapses that into three clicks — highlight the post, pick a tone, paste the reply. HOW IT WORKS 1. Highlight any post or comment on a supported site 2. A small button appears next to your selection — click it 3. Choose a skill, read the generated reply, and hit Paste The reply drops straight into the native reply box, where you can edit it like anything you'd type yourself. Nothing posts automatically. You always press the final button. SKILLS — THE CORE IDEA A skill is a short instruction that tells the AI how to reply. Ship with three built in: - Thoughtful — adds a real perspective instead of empty agreement - Witty — sharp and funny without trying too hard - Agreeable — warm, supportive, good for building rapport The real power is writing your own. A skill can be a persona ("reply as a senior backend engineer"), a voice ("match my brand tone: direct, no fluff, lowercase"), a constraint ("always ask a follow-up question"), or all three. Build one per context — one for your work account, one for your niche, one for the community you're most active in — and switch between them from the panel. Custom skills sync across every device you sign in on. CONTROLS - Reply length — pick 280, 500, or set your own character limit - Regenerate — not quite right? Get another take on the same post - Copy — grab the text without pasting, for use anywhere - Edit freely — the reply lands in the normal composer, fully editable WHERE IT WORKS - X (Twitter) — posts and replies - Instagram — captions and comments - YouTube — video titles, descriptions, and comments WHO IT'S FOR Founders and creators keeping up with a busy timeline. Marketers managing engagement across accounts. Job seekers and career builders trying to be visible in their industry's conversations. Anyone who reads a good post, wants to add something, and doesn't want to spend ten minutes on two sentences. PRICING Free — 10 AI replies per week.
