AI answers get written from Reddit threads.

Ask ChatGPT, Claude or Perplexity for the best tool in your space and the reply leans on what real people said on Reddit. Get to the thread early and you can be part of the conversation the model ends up quoting.

The reply you need is usually a comment.

Plenty of tools stop at the post title. The recommendation you want tends to sit three replies deep, so we read every comment too, right across Reddit.

  • Comments and posts. The buying signal is often a reply, not the headline.
  • A check every 5 minutes. You hear about a thread while it is still live and getting indexed.
  • Phrases up to 200 characters. Match a full question, not a single word.

Questions, answered straight

What is a Reddit monitoring tool?

It is a tool that keeps an eye on Reddit for the words and phrases you care about, then tells you when they turn up. subding reads posts and comments every 5 minutes and routes the alert to Slack, Discord, email or a webhook, so there is no feed to sit and refresh.

How do you keep an eye on Reddit?

You hand us a keyword, we read Reddit for it, and the ping goes out the second it appears. Set your channel once and leave it. We only ever read and notify, never post, reply or DM for you.

Does it cover comments as well as posts?

Both. The recommendation worth catching is often a reply buried deep in the thread rather than the original post, so we read comments and posts across the whole of Reddit.

How fast are the alerts?

The check runs every 5 minutes, so the ding goes out on the next pass after your keyword shows up. Early enough to join the thread while it is live and getting indexed. Need it quicker? Drop us a line.

Where do the alerts land?

Slack, Discord, email or a webhook, and you can run several at once. The webhook carries the full JSON, so alerts can flow into Zapier, Make, n8n or whatever you have wired up.

Is this a scraper or an auto-poster?

No. It reads and notifies, nothing else. We flag the mention and stop there, so there is no posting, commenting, replying or DMing on your behalf. What happens next is your call.

How much does a Reddit monitoring tool cost?

Plans are $19, $49 and $149 a month. What moves between them is the keyword count: 15, 75 or 250. Every feature sits on every plan.

Is there a free trial?
