Replies that sound like a person
Answering comments keeps a conversation going. Itâs also slow when half the comments ask the same question, and hard when one of them is angry.
Paste a comment or message, pick a style and get replies you can post or tweak. Pick a network above and the reply follows that networkâs habits.
Reply limits by network

How replies differ by network
Instagram, Facebook, YouTube, TikTok, LinkedIn and Reddit donât publish a comment length. Use Shorter for a quick reply and Longer when the answer needs detail.
- Instagram: short and warm. Answer the question, and tag no more than 5 people, the most Instagram allows in one comment.
- YouTube: replies stay under the video for every future viewer. A helpful answer works like a mini FAQ.
- TikTok: keep it light. A good question in the comments can become your next video.
- LinkedIn: add something, like a detail or a question back. âGreat post!â adds nothing.
- X: brief and on point. A reply is a post, so the post limit applies.
- Facebook: write the way a neighbor would. Use the personâs name when you know it.
- Reddit: answer the question and skip the pitch. If itâs your product, say so, and follow the subredditâs rules.
When a comment is negative
- Reply once, in public, with a fix or a next step. Then take the details to DMs or email.
- Answer the problem, not the tone.
- Check every fact in the draft. The generator doesnât know your refund policy or shipping times.
- Leave anything about money, safety or legal trouble to a person.
