This is a submission for the Runner H "AI Agent Prompting" Challenge

What I Built

I created a writing prompt generator that pulls real questions and reflections from Reddit's writing and self-improvement communities. It automatically compiles them into a clean Google Doc so I always have fresh, relevant prompts to write from.

How I Used Runner H

I had a lot of daily writing tasks I wanted to automate, and one of them was generating high-quality prompt ideas based on what people are actually struggling with or curious about.

At first, I tried scanning Reddit directly with a prompt like:
“Go through the latest posts and comments in subreddits like r/Freelance, r/SaaS, r/Productivity, r/UXDesign, r/Entrepreneur, and r/SmallBusiness. Look for phrases like 'I wish...', 'this sucks...', or 'why can’t I just...' and log them into a Notion database.”
But it couldn’t search Reddit due to authentication limits.

Then I tried using Google with terms like:

• “how to” site:reddit.com/r/writing
• “tips for” site:reddit.com/r/freelance

That didn't work either. I still thought the idea had potential, so I gave it one more shot using RSS feeds.

Here’s the final working prompt:
“Fetch the latest RSS feeds from both the writing and self-improvement subreddits. From each feed, extract user-generated posts that are either direct questions (starting with what, how, why, etc.) or reflective statements. Skip external news sources. Clean up the content, and include the title, author, Reddit link, and publish date. Then compile everything into a Google Doc titled 'Writing + Self-Improvement Prompt Vault.'”

It worked.

Here’s an example of how it logs each entry in the doc:

1. Title: how the fuck do you find purpose  
   - Author: u/earlyhazee  
   - Link: https://www.reddit.com/r/selfimprovement/comments/1lsrivo/howthefuck_ddou_finfindose/  
   - Date Published: 2025-07-06T03:26:29+00:00  
   - Content: Seeking advice on finding purpose and meaning in life after overcoming depression and social media detox.

This was specifically for my writing niche but you can edit the subreddits in the prompt based on what kind of prompts or niche you want. It’s a reliable way to get real writing topics that people actually care about. And its not just writing, if you are looking for ideas on services to provide or products to build, this is one way to see real life pain points and get to know what people really want.

Use Case & Impact

Writers often struggle with content ideas. This automation solves that by pulling real community questions—things people are actively asking. Whether you're a blogger, content creator, or building a personal writing habit, you’ll never run out of ideas. It works especially well for niche-focused creators.
