Getting more comments on your own YouTube posts
Many people arrive here looking for free comments on their own videos or posts. No tool can give you real ones, and services that sell comments break YouTube's rules on fake engagement. These work instead:
- End with a question people can answer in a few words, and put it in the caption or on screen, not only in the voiceover.
- Ask for something specific, such as a vote between two options or a tip from their own experience. "Thoughts?" rarely gets an answer.
- Reply to the first comments quickly. Replies keep the thread going and show newcomers that you answer.
- If you can pin a comment, pin one that invites an answer: your own question, or the best comment so far.
- Post when your audience is usually online; your account's analytics show when.
YouTube Comment Generator FAQ
How does the AI YouTube comment generator work?
You describe the video and choose an intent and a tone. The AI drafts a comment from your description only: it doesn't watch the video, so add a timestamp or a detail from it to show you did.
Can comments help my channel grow?
They can. A useful comment under a related video can bring viewers to your channel, especially when it rises to the top. It's slow and not guaranteed, and repeated self-promotion counts as spam on YouTube.
What makes a good YouTube comment?
Thoughtful, specific comments that add genuine value, ask meaningful questions, or share personal insights related to the video content perform best. Our generator helps you craft comments that stand out from generic responses and encourage the creator and other viewers to engage with you.
Should I comment early on new videos?
It can help. Early comments have more time to collect likes, and YouTube shows the most popular comments first by default. Being early only helps if the comment is worth reading.
How long should YouTube comments be?
Medium-length comments with specific insights and genuine value tend to get the most engagement on YouTube. Aim for 2-4 sentences that demonstrate you actually watched the video and have something meaningful to contribute to the conversation around the content.
Can I generate reply comments?
Yes. Describe the comment you're answering and pick an intent; the draft works as a reply. Replies under popular comments are read by many viewers, so make them worth reading.
Should I use timestamps?
They help when they point to something specific. A timestamp shows you watched the video, and YouTube turns times like 2:15 in a comment into links that jump to that moment.
Is there a limit to comments I can generate?
Each generation uses AI credits from your PostNext plan: 10 a month on the free plan, 150 on Premium and 500 on Business. Generating needs an account, and new accounts start with a 7-day free trial that asks for a card.
Posting AI-drafted comments on YouTube the right way
Treat every result as a draft. Read it, change anything that isn't what you think, and add a detail only you would know. A comment that sounds like you gets replies; a generic one gets scrolled past.
Never paste the same comment under many posts. YouTube's spam rules, like those of every major network, cover repetitive comments, and accounts that do it can be limited.
Leave links out of comments. They read as self-promotion, and spam filters often hide them.
This tool only writes drafts. You choose one and post it yourself on YouTube, so every comment stays yours.
