AI reply generator for Reddit and X
updated 1 November 2026
Paste a Reddit post, a comment or a tweet, and this AI reply generator drafts one public reply in the tone of the place it was posted. If you add what you sell, the reply may mention it once, and only when it answers what the person asked. Leave it blank and you get a plain, helpful answer with no product in it.
It never posts anything. You copy the draft, make it sound like you, check the community's rules with the subreddit rules lookup, and post it yourself.

How it works
- Paste the post or comment you want to answer, up to 1,500 characters.
- Pick where it was posted. Reddit replies come out conversational, usually 40 to 120 words. X replies stay under 270 characters with no hashtags.
- Optionally add the community, like r/agency, and a line about what you sell.
- You get one draft, a note on whether it names your product, and a sentence on why the reply is shaped the way it is.
Each visitor gets 5 drafts a day. The same post with the same details returns the same draft for a day, so change a detail if you want a different one.
Not sure the post is worth answering? Run it through the buying intent scorer first. A score of 70 or more means the writer is looking for something now.
What makes a reply survive on Reddit
Most Reddit communities remove replies that read like ads, and readers downvote them faster than any moderator can. The replies that stay up usually have these traits in common:
- They answer the question first. If someone asks how other agencies handle reporting, the reply describes a way to handle reporting before it names any tool.
- They are specific. "We cut it to two hours by templating the five charts every client asks about" beats "there are many great tools out there".
- They mention a product once, with a disclosure. "Full disclosure, I work on one of these" next to two or three other options reads as honest. A link with no context reads as spam.
- They match the room. No headings, no emoji, no sign-off. Short paragraphs, the way people write in comments.
- They follow the rules. Many subreddits ban self-promotion outright or only allow it in a weekly thread. Read the rules before you post, every time.
The generator aims for all five, but only you know whether the advice is true for you. Edit anything you can't stand behind.
Sample
A sample post from r/agency: "We're a 6-person agency and our client reporting takes a full day every month. How are other small agencies handling this?"
With "reporting dashboards for agencies" as what you sell, the draft opens with how to cut the work (agree on a fixed set of metrics per client, automate the data pulls, write the commentary last), then names the product once as one option among a few, with a disclosure. Without a product, it stops after the advice.
Finding posts worth replying to
The generator answers one post at a time. Finding those posts takes longer, because someone has to read the communities every day and spot the few people asking for help. Reddit monitoring in HearBuyers does that reading on X and Reddit, scores every match for buying intent, and drafts a reply for the strong ones. A person still approves and posts each one. The Reddit lead generation guide covers the whole routine, from picking communities to following up.
Frequently asked questions
Is this AI reply generator free?
Yes. There's no sign-up, and each visitor gets 5 drafts a day.
Does it post the reply for me?
No. It only drafts. You copy the reply, edit it, and post it from your own account after you've read the community's rules.
Will it always mention my product?
No. It names your product at most once, and only when it fits what the person asked. If it doesn't fit, the draft leaves it out, and the note under the draft says so.
Can I use it to reply to tweets?
Yes. Pick X as the platform and the draft stays under 270 characters, with no hashtags and no links.
Is it a comment reply generator for any site?
It's written for Reddit and X. The advice in a draft usually carries over to other communities, but the tone and length rules are tuned for those two.
Is my post stored?
The draft is kept for a day so the same request doesn't run twice. Don't paste anything private.
