How do you use reply-with-video on TikTok?

Short answer: Tap any comment on your video — or someone else's, if they've enabled it — hit the video-camera icon in the reply box, and film a response. The comment appears as a sticker on your new video. It's a fast way to answer questions, turn good comments into fresh content, and show viewers you read what they write.

How to do it

Open the comments on a video — usually your own, or someone else's if they've enabled video replies.
Tap the comment you want to answer, then tap the video-camera icon in the reply box.
Film your response. The comment shows up as a sticker on your new video, which you can drag and time however you like.
Add captions, text, or a sound, then post it as a normal video to your profile.

The comment-as-sticker is the whole trick — viewers instantly see what you're responding to, so your video has built-in context and a ready hook. It posts as a standalone video on your feed, not buried in a comment thread, so it can reach the For You page like anything else you make.

Why it's one of the best growth habits

You never run out of ideas — your comments are a running list of exactly what your audience wants to know.
The comment is a built-in hook, so the video starts with a reason to watch.
It shows you actually read and respond, which is how casual viewers become a community.
Answering questions builds authority in your niche without you having to invent a topic from scratch.

Watch your comments for the same question asked over and over — that's a video begging to be made. Reply-with-video turns your audience into your content planner, and the people who asked feel seen when you answer them on camera.
