Reddit moves too quickly to monitor by hand
The useful conversations are scattered across posts, comments, and niche communities:
- 🎯Potential customers with a problem that your product solves
- 🔍Users of your competitor's product voicing valuable complaints
- 🛡️Negative reviews of your brand that you can still turn around
- 📰Story leads breaking in niche communities before the news catches up
The hard part is not finding more Reddit posts. It is finding the few that are worth acting on.
Keyword alerts help, but they're not enough
Say you're a journalist covering the EV industry. You're watching r/TeslaMotors for owner complaints about build quality.
Alerts you about
"No Tesla problem here, best car I've owned"
Contains the keyword, but it is praise.
"Tesla issue fixed under warranty in two days"
Contains the keyword, but it is a happy customer.
Stays silent about
"Panel gaps are terrible on my new Model Y"
A real complaint, but it never says "problem" or "issue".
Alerts you about
"Panel gaps are terrible on my new Model Y"
No keyword in sight. The AI reads it as frustration.
"Service center has been ghosting me for three weeks"
A service complaint phrased in words you did not predict.
Stays silent about
"No Tesla problem here, best car I've owned"
Praise is not frustration, so no alert.
RedditAlert gives you the tools to find exactly what you need
🧠AI-powered queries
Write a prompt describing the conversation you want to catch. RedditAlert evaluates posts and comments for intent, not just exact words.
Just launched my AI writing tool. Be honest, what would you change?
Built a habit tracker over the weekend. Roast it before I launch?
🔧Regular expressions
For power users who need precise pattern matching. Full regex support for exact control over what triggers an alert.

[Hiring] Looking for engineer with React/Node experience - $120k-150k
🔀Complex queries
Combine conditions with AND and OR, mixing regex precision with AI judgment in a single alert. This one catches people who mention a competitor budgeting app and are actually shopping for a replacement. Every condition narrows the noise.
The author is unhappy with their budgeting app and looking for a replacement, not promoting their own product
⚡Real-time notifications
Get notified within 30 seconds of a matching post or comment being submitted.
Start simple with keywords. Add AI when you need context. Use regex when the exact pattern matters.
From a sentence to a live alert
Describe what you want to monitor. The assistant suggests the right communities and writes the matching rules, you review and tweak, and you are live in under a minute.
RedditAlert assistantI sell an email marketing tool. Alert me when people complain about Mailchimp's pricing.
I created mailchimp-pricing-complaints monitoring r/Emailmarketing, r/MailChimp, and r/smallbusiness.
Just describe what you want
Tell the assistant what you want to catch in plain language, like "alert me when people complain about Mailchimp's pricing." No query building required.
Review the draft and tweak it
The assistant picks the subreddits and writes the matching rules. Adjust it by chatting or editing, and do a test run to see exactly what would match before it goes live. Regex and boolean logic (AND/OR/NOT) are there whenever you want precise control.
Get real-time email alerts
When a matching post or comment is submitted, you get an email within 30 seconds with a direct link. There's also a web dashboard where you can see all of your alerts and matches.

Frequently asked questions
What if I don't find what I'm looking for?
You have 14 days to try it risk-free. If RedditAlert doesn't work for you, we'll refund you, no questions asked.
Start with a few alerts in your target subreddits and refine them as you learn what matches best.
How is this different from Google Alerts or F5Bot?
Google Alerts: Simple keywords only. No AI, no regex, no boolean logic, and no Reddit comments. It also waits for Google to index a page, so alerts often arrive hours late.
F5Bot: Keyword matching with 5-minute batched delivery (free tier: 50 alerts/day cap). No AI filtering, no query engine, no dashboard.
RedditAlert: A full query engine built for Reddit. Match by intent with AI prompts, or get precise with regex and boolean logic (AND/OR/NOT). It watches posts and comments in real time (under 30 seconds), and you can test a query before it goes live.
Will I get spammed with irrelevant alerts?
That depends on how you set up your alerts. With keywords alone, you'll likely get noise. But you can use AI prompts to filter by intent. Just write "people frustrated with X" and the AI understands what you mean.
You also have regex + boolean logic (AND/OR/NOT) for precise control.
And you can keep refining a query as alerts come in and you notice ones you don't want. Before a query goes live, you can also do a test run, which works like a Reddit search powered by the RedditAlert query engine, so you can see what it would catch and adjust it first.
How does the AI prompt matching work?
Instead of relying on keywords alone, you can describe what you're looking for in plain language, like "someone asking for tool recommendations." The AI then checks every new post and comment for that intent before it ever reaches your inbox.
You can combine it with keywords, regex, and boolean logic (AND/OR/NOT) when you need precise control.

A note from the founder:
Hi, I'm Murilo. I built RedditAlert because I felt that the existing solutions didn't do a good enough job. They were either too simple (keywords only) or focused on many platforms without doing Reddit well.
I wanted something with powerful querying (AI + regex + boolean logic) that only sent alerts I actually care about.
So I built RedditAlert.
If you have questions or feedback, email me at murilo@redditalert.com. I read every message.
