Reddit monitoring tool that reads posts and comments for your keywords.
Pick the words worth hearing about. We keep an eye on Reddit around the clock and send the ding to Slack, Discord, email or a webhook the second one lands.
"we keep finding out about brand threads days too late. anyone using a decent Reddit monitoring tool that actually pings you fast?"

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.
See how Reddit shapes AI answers → 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.
"piggybacking on this one, we're in the same boat. is there an email marketing tool you'd actually recommend that isn't a pain to set up?"
→ Reply while it’s fresh
Sent to the channel you already open.
One alert, delivered wherever suits you. Nothing new to log into and no extra tab left open all day.
Two minutes to set up. Then it runs itself.
Add the words worth hearing about and carry on with your day. No sentiment scoring, no charts to read, just the ding when it counts.
- It reads, you don't. We handle the checking so you never sit and refresh a feed.
- Track what earns you money. Your brand, a rival, or the phrase people search right before they buy.
How the monitoring works
- 1 Add a keyword Your brand, a rival or a phrase. Up to 200 characters.
- 2 We keep watch Reddit posts and comments get read every 5 minutes in the background.
- 3 You get the ding Straight to Slack, Discord, email or a webhook. You choose which.
Give it a week and see what lands. Start a free trial, no card, and judge it on real threads.
We read and notify. That is the line we hold.
No scraping, no auto-posting, no reply bot. We spot the mention, flag it, and stop there. Built for Reddit and careful about how, so the next move stays yours.
The short version
Plans are $19, $49 and $149 a month. You pick how many keywords to track; the rest is identical on all three.
Reddit search was never built to watch for you
Reddit’s own search shows you what exists at the moment you look. It does not tell you when something new appears, it sorts by relevance unless you remember to change it, and comments barely surface at all. So most teams fall back on someone checking a few subreddits by hand, usually on a Monday, usually after the useful threads have filled up.
The cost is easy to miss because you never see it. A thread asking for a tool like yours gets its best replies in the first few hours. Arrive two days later and the answer is written, upvoted and, increasingly, read back by ChatGPT, Claude and Perplexity when someone asks the same thing. A monitoring tool closes that gap by doing the checking on a fixed clock, so the first you hear of a thread is a ping rather than a stale search result.
Three alerts worth getting
Made-up threads, written to show what a sensible keyword list catches in a normal week.
-
we’re drowning in late payments. does anyone have an invoicing tool they’d actually recommend for a five-person team?
→ Worth a look while it’s live
Why it matters: A buying question, asked in a reply under someone else’s post. A tool that only reads post titles never sees it.
The next move: If you make invoicing software, a short answer about how you handle payment reminders, saying that you work there, with no link unless they ask.
-
postman keeps getting heavier for what we need. is there a lighter alternative to Postman for testing a handful of endpoints?
→ Worth a look while it’s live
Why it matters: “Alternative to” is about the clearest switching signal there is, and this one names the tool being left behind.
The next move: Reply with the honest trade-offs, including the cases where Postman is still the better pick.
-
has anyone here tried Tallybird? thinking of moving our bookkeeping over but there aren’t many reviews yet
→ Worth a look while it’s live
Why it matters: Someone weighing your product with very little to go on. Whatever gets said next will shape the decision.
The next move: Answer what was asked, say who you are, and point to the docs page that settles the question.
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?
Seven days, no card needed. Add a keyword and watch what comes in. Cancel whenever you like.
