the lazy way to turn Reddit into your best sales channel
This automation will cost less than $5 per month to implement.
Last month, I stumbled across a Reddit thread that made me realize I had a problem.
Someone was asking for “Zapier alternatives that don’t cost a fortune.”
The thread had blown up—tons of upvotes, active discussion. Three competitors had already jumped in with their pitches.
The thread was several days old. I was too late. Again.
That’s when it hit me like a ton of bricks: How many conversations like this was I missing?
If even a fraction of these threads could lead to customers, I was potentially losing thousands of leads every month just by not being present.
Social listening tools want $300-500/month for basic Reddit monitoring.
As someone who’s built dozens of n8n workflows specifically to avoid overpriced SaaS subscriptions, paying that much for what’s basically keyword alerts?
Nope.
So I built this AI-powered Reddit monitor that:
✔ Catches every relevant mention
✔ Filters out the noise
✔ Delivers exactly what matters
Cost? Around $5/month in API credits. Sometimes less.

Why Manual Reddit Monitoring Is Not Feasible
I have this founder friend who spends 3 hours every morning searching Reddit for brand mentions.
His routine? Coffee, quick email check, then straight into the Reddit vortex until lunch.
Here’s the brutal math nobody talks about:
3 hours/day × 5 days = 15 hours/week
15 hours × $100/hour opportunity cost = $1,500/week
$6,000/month literally burned on scrolling
But wait—it gets worse.
Reddit threads have this 24-hour golden window.
After that the algorithm buries them.
Engagement dies.
Your perfectly helpful response?
Nobody sees it.
Quick story from my enterprise experience: We discovered that responding to user feedback within 2 hours increased positive sentiment by 73%. Not 72%. Not 74%. Exactly 73%. (We measured everything.) Same principle applies here—speed beats perfection.
What You’ll Actually Need (No BS Version)
Prerequisites:
n8n instance (*self-hosted saves you $20+/month vs cloud*)
Reddit account with API access (free, takes 5 minutes)
OpenAI API key (*$5-10/month for moderate use*)
Basic understanding that Reddit isn’t just memes and drama
Real setup time:
30 minutes if you follow along
2 hours if you’re a perfectionist like me
Monthly cost breakdown:
n8n self-hosted: $5 (DigitalOcean droplet)
OpenAI API: $5-10 (depends on post volume)
Step 1: Connect to Reddit’s API (Without Losing Your Mind)
Confession time: Reddit’s API documentation reads like someone translated a legal contract through Google Translate.
Twice.
My law degree finally proved useful for something.
Reddit API Setup That Actually Works:
Go to
reddit.com/prefs/apps(while logged in)Scroll allll the way down, click “Create App”
Name: Whatever you want (seriously doesn’t matter)
Type: Script (for personal use)
Redirect URI:
http://localhost:8080 (this should later be changed to your hosting instance’s URL)
(Reddit needs this, just roll with it)
Hit “Create app”
Critical stuff nobody mentions:
User Agent: Has to be unique (*I use "n8n-monitor-v1"*)
Rate Limits: 60 requests/minute (more than enough)
Scope: Just need “read” access
Learn from my mistake: Don’t use your main Reddit account. Create a bot account.
Step 2: Search and Filter (The 90/10 Rule in Action)
This is where we separate the wheat from the chaff. Or signal from noise. Or... you get it.
Search Config That Actually Works:
Operation: Search
Location: All Reddit (not specific subreddits)
Keyword: Your exact brand name
Sort: New (catch ’em while they’re hot)
The Holy Trinity of Filters:
Upvotes ≥ 5: Kills zero-engagement posts
Has text content: No link-only spam
Posted within 7 days: Fresh discussions only
Step 3: AI Classification (Where the Magic Happens)
Time to separate “I love n8n workflows” from “I had n8n shots at the bar last night.” (Yes, that second one actually happened. Still confused about it.)
The Classification Prompt That Just Works:
Decide whether a reddit post is about n8n.io, a workflow automation low code tool that can be self-hosted, or not.
Reddit Post: {{ $json.selftextTrimmed }}
About n8n?: Yes/No OpenAI Settings for Cheap Skates Like Me:
Model: GPT-3.5-turbo (*GPT-4 is overkill here*)
Max tokens: 32 (literally just need "Yes" or "No")
Temperature: 0 (consistency > creativity)
Real Results After 90 Days
Time reclaimed:
10-15 hours/week not doomscrolling Reddit
Response time: Used to be 1-2 days → Now 2-4 hours
Weekend monitoring without actually working weekends
Business impact:
Caught and engaged with dozens of high-value conversations
Multiple direct sales from Reddit
Revenue I can directly attribute to Reddit
Stop Leaving Money on the Table
This workflow turned Reddit from a time sink into my best customer acquisition channel.
Not through spam.
Through consistently helping people who need what we built.
Those $300+/month listening tools? Wrong solution. You don’t need more alerts. You need smart filtering that respects your time.
Final thought: The fear of “self-promotion” on Reddit keeps founders from helping people who desperately need their solutions. This workflow ensures you show up for the right conversations at the right time.
Your future customers are asking for help right now. This automation makes damn sure you’re there to answer.
(Actually, let me rephrase that—your competitors are probably already answering. This makes sure you get there first.)
