How I Built a Reddit Market Intelligence AI Agent That Saves Me 3+ Hours Per Week
Get weekly digests of market insights, trends, and opportunities, without manual scrolling.
I don’t like spending time on Reddit.
The platform has this strange mix of brilliant insights buried under toxic comments and pointless arguments. Every time I open it to look for something, I find myself scrolling through thread after thread trying to separate signal from noise, and an hour disappears before I realize it.
But I can’t afford to ignore Reddit.
And if you’re building anything, running a business, working in a big company, creating content, or trying to understand what people need, you can’t either.
Because Reddit is where people talk when they think no one important is listening. They complain about tools that almost work but don’t quite solve their problem. They ask for recommendations when they’re ready to buy. They share the workarounds they’ve built because nothing on the market does what they need. They post before and after stories when something works.
379.4 million people use Reddit weekly and 40% of internet users say a Reddit recommendation is more influential to their buying decision than reviews or influencers. So yeah, can’t really ignore that.
And because I needed the insights but hated the hours it took, I built a system to do it for me.
Now an AI agent handles all the Reddit scrolling. It scans threads weekly, pulls what’s relevant to me, analyzes everything, and sends me a clean digest. I get better market intelligence and audience insights than I ever did manually, without even opening the app.
I’ve been running this for a few months now and it works better than I expected, so I’m sharing the complete setup with you today.
What happened when I used Reddit to validate a product idea
Earlier this year, I spent about a month on Reddit tracking career change conversations. I was validating a career discovery product idea with my friend, Matei, and we needed to understand the market. Every day, I’d dive into threads, join discussions, offer free trials and consulting in DMs to watch how people responded.
Here are my DMs from back then (but I was even more active in comments):
The data we collected was gold. We discovered that the people who needed our solution most (students, career changers, unemployed professionals) couldn’t pay for it. And those who could pay weren’t actually ready to make the bold career change - they just wanted to vent about their situations.
That validation helped us kill the idea before we wasted more time and money on it. At least in that form of how we initially thought of it.
That’s how I learned that Reddit is one of the best market intelligence tools available.
What makes Reddit different from any other platform
When someone discovers a product anywhere else (an ad, a recommendation, a social media post), 71% of them go to Reddit to research it before buying. In other words, Reddit has become the reality check for everything found elsewhere. Pretty wild, isn’t it?
And it’s not just research. 88% of Reddit users made a purchase based on information they found on the platform in the last year. And 74% report being satisfied with those purchases.
This means two things:
First, if you’re building or selling something, your potential customers are on Reddit right now discussing whether your solution is worth it. They’re comparing you to alternatives. They’re asking if you’re legit. You need to know those conversations are happening.
Second, if you’re creating content, trying to validate a product or understand your market, Reddit shows you exactly what language people use, what problems they can’t solve, and what solutions they’re willing to pay for.
That’s why ignoring Reddit is expensive. But so is spending hours there manually, which is why I automated it.
How I use Reddit now (without actually using Reddit)
These days, a lot of my time is spent writing here and continuing to build AI solutions: products, automations, prompts. Reddit is still one of my go-to places for market intelligence, but I’ve automated the entire process.
The system I now have in place collects AI insights, business ideas, content inspiration, and market signals, all without me opening the app.
What this looks like in practice:
Content ideas flow constantly. When someone posts “I wish there was a way to...” or “Why doesn’t anyone build...”, that’s a content topic handed to me on a silver platter. I don’t have to guess what people care about. They’re literally telling me.
I stay ahead of trends. When a specific prompt technique or AI tool starts showing up in multiple threads, I know it’s gaining traction. I can write about it, test it, or build something around it before it becomes mainstream.
I spot patterns in frustrations. When five different people in different subreddits complain about the same problem with slightly different wording, that’s a signal - an opportunity to create something that actually solves it.
I get inspiration from real examples. People share their prompts, their workflows, their failed experiments, their unexpected wins. I don’t have to imagine use cases. I’m seeing exactly what people are trying to do and where they’re getting stuck.
I understand the language people use. When someone says they’re “overwhelmed by their inbox” versus “drowning in email” versus “can’t keep up with messages”, those are different emotional states. The automation captures this exact wording so I can speak the same language in my content.
The AI suggests what I should build next. Because the system has context about what I do (automations, AI products, prompts), it can look at a frustration and suggest: “You could address this with a workflow that...” Sometimes the suggestions are obvious. Sometimes they’re brilliant. Either way, I’m never staring at a blank page wondering what to create.
The automation runs in the background. And I still get better market insights than I did when I was manually searching.
What the Reddit automation does
Instead of manually searching Reddit, once a week (you can customize the frequency), the system:
It finds the conversations that matter to you - monitoring your chosen subreddits and only pulls threads that match your keywords and have enough upvotes to be worth reading.
It reads and understands each thread. An AI agent analyzes every post to figure out what the person is actually saying and if it’s relevant to what you’re actually looking for.
The AI agent organizes everything into categories. Is it a frustration? A question? A tip someone shared? An idea? The system sorts them however you please so you can quickly find what you need.
It gives you the key takeaway and spots patterns. Instead of reading entire threads, you get a 1-2 sentence summary of the main point and assigns themes so you can see what topics keep coming up.
It tells you what to do with it. For questions and frustrations, I’ve set up my automation to have the AI agent suggest how I could address it or what I could build to solve it based on what I do and my experience.
It saves everything in one place. All the data goes into Airtable (but you can change to Sheets): post titles, summaries, links, upvotes, categories, themes, and suggestions.
It delivers a clean digest to your inbox. Every week (or however often you want), you get one email with everything organized and ready to act on.
Remember those weeks I spent on Reddit validating the career product? I was manually searching for relevant threads for hours every day. With this system, I could’ve set it to run daily and gotten everything delivered to my inbox automatically. Would’ve saved me so much time.
Who can benefit of this
This system works for anyone who needs to understand their market, audience, or industry. The only difference is the subreddits you track and the keywords you use.
What this system costs (and what it saves)
n8n has a free tier if you self-host, or $20/month for cloud.
Gemini API costs pennies per request (or you can use ChatGPT or Claude instead). I didn’t track this specific automation’s cost, but last month I spent $12 total on Gemini across 6 automations (some using image generation, which is more expensive).
Airtable is free for this use case (or you can use Google Sheets instead, connecting like I did in this automation).
Compare that to spending 3+ hours per week manually tracking conversations.
And it’s not just the time. It’s the inconsistency. You don’t do it regularly because it’s tedious. You miss valuable signals from the market. You get tired of reading and stop paying attention. Important conversations slip past you because you weren’t online.
So let’s not let that happen anymore. Set it up once. It takes about 30 minutes, and then you’ll get your market insights digest without even opening Reddit.
Complete step-by-step setup guide
I’ll walk you through the full setup step by step and show how each part works, with screenshots.
The best part? You only need to:
Connect four nodes - Reddit, Gemini, Airtable, and Gmail
Choose your subreddits and keywords (as shown in the first two steps below)
Customize the prompt for your goals
That’s it. Everything else is already built for you. Once these pieces are in place, the system runs on its own and delivers your Reddit insights automatically every week.
Step 1: Find the scope
Decide exactly what you want to collect from Reddit.
Keep one workflow focused on one purpose. Don’t mix very different goals in the same workflow.
For example, don’t mix personal research (tracking business ideas you could build) with work tasks (monitoring what people say about your company’s product) in the same workflow. Those needs live in different subreddits and require different keywords and LLM prompts.
Why this matters: when you ask one AI agent to interpret many different kinds of posts, the results might get messy and harder to use.
How to handle multiple signals: if you want to track more than one thing, clone the workflow and tune each prompt for a specific scope.
Step 2: Pick subreddits, keywords, and flairs
Decide where you’ll listen and what words you’ll listen for.
Find the subreddits where your scope shows up. There are two quick ways to find them:
Manual: Go to Reddit and search for terms that match your scope. Open the subreddits that come up and skim top threads and comments. Save the subreddit names you find relevant for your scope.
Use a search helper (Perplexity or similar): Ask it: “Which subreddits and starter keywords should I watch for [your topic]?” Use the results as a checklist to find subreddits and keywords faster.
Then, inside each subreddit, collect keywords and flairs
Now that you picked the subs, you’ll need keywords to watch for so you reach relevant posts. These become the signals your automation watches for.
You can think of your own keywords
Or use subreddit flairs and tags. Flairs are useful because they reflect how the community labels and groups posts. They usually appear next to post titles and also show up in the Create Post form.
Here’s a prompt to find the exact subreddits and keywords you need.
Step 3. Import the workflow into n8n
Go to n8n.io and sign up or log in.
Once logged in, click “Create Workflow”.
