Varnan

If you’re building a product, the hardest thing is knowing what your users are actually struggling with. You can run surveys and talk to a few users, but that doesn’t scale. The truth is, your potential users are already talking about their pain points in public they’re just doing it on Reddit , Hacker News and X etc.

Now, no one has time to scroll forums for hours, and even if you do, most of that data never gets stored, structured, or used.

That’s why we at Varnan built a fully no-code AI Agent that does all the hard work for you.

The Problem: Founders are guessing what to build

Every founder thinks they know what users want. But when you ask where the data is coming from, you usually hear:

“Oh, I sometimes go through feedback forms or search google/social media when I have time.”

Here’s what most early teams are actually doing:

Randomly searching product pain points
Skimming Reddit threads with no clear outcome
Clicking through tons of links, post and comments with no way to summarize them

No system, no reports, no automation

So we thought: what if you could just enter your product idea and get a ready-to-use pain point report?

The Agent Workflow

We used n8n + OpenAI + Google Gemini + Reddit + Hacker News + custom AI agents to build a fully automated user research assistant.

Here’s how it works, step-by-step:

1. Webhook Trigger from a Form

As first the step, The flow begins when someone submits a simple form — usually with just a product idea or a broad category.

2. Generate Keywords Using AI

Then, We run the input through a GPT-based AI Agent that turns it into relevant keywords. These are actual search terms that users might be typing on Reddit or Hacker News.

Think:
“marketing automation tool” → keywords like: “email sequence pain”, “mailchimp vs convertkit”, “crm frustration”

3. Split Search by Platform

Now for the third step, we break the keywords into smaller groups and route them based on where they’re most relevant. For example:

Tech-focused terms go to Hacker News
Product-related pain points go to Reddit

4. Reddit & Hacker News Scraping

Now, The automation runs live searches on Reddit and Hacker News using APIs and OAuth. It fetches:

Real user posts
Threads with high engagement
Long-form discussions

And skips the fluff.

5. Custom AI Agents Read and Extract Insights

Now, at the Fifth step. Here’s the real magic happens.

Two separate AI agents (one for Reddit, one for Hacker News) read the content and extract:

Repeated complaints
Feature requests
Unmet expectations
Product comparisons

6. Merge, Filter & Format the Output

After that, All results are filtered and cleaned — removing duplicates or vague responses. Then the content is merged into a unified report.

7. AI Agent Creates Final Report

This is where the output becomes useful.

An AI agent summarizes everything into:

Clear pain point clusters
Feature gaps users are talking about
Trends or unmet needs in that space
Specific subreddits or HN threads that matter

8. Send the Report to Your Inbox

Lastly, the report is converted to HTML and emailed to you.

clean, readable, and ready to use. No JSON dumps, no mess.

What the Report Includes:

Top User Pain Points
Suggested Product Features
High-Engagement Reddit Threads
Hacker News Discussions Worth Reading
Niche Communities to Watch
Summarized Takeaways

Everything is real-time. Everything is traceable. And it’s all built with no code.
