How to Build a Reddit Content Agent With Lovable 2.0

TL;DR

Build a no-code content engine by connecting a Lovable 2.0 dashboard to two n8n webhooks: one scrapes Reddit by subreddit, keyword, and sort type (hot, top, or new), the other turns any qualifying post into Twitter, Instagram, LinkedIn, or Shorts content with three angle options plus a generated image emailed to you.

Key Insights

• The idea is about 80% of content performance, according to the creator's conversations with channels holding up to 5 million subscribers. Title, thumbnail, and hook matter, but if the underlying idea is poor the content will not perform.
• Reddit signals real demand because a person cared enough about a problem to post it, and high upvotes mean it is a topic of interest. The system finds those validated topics so you never have to guess what your audience wants.
• The system takes three inputs: whether you want hot, top, or new posts, the subreddit, and the topic keyword. A button selector handles the sort type while the subreddit and keyword are typed in.
• A double webhook integration drives the flow. Webhook A receives the inputs and searches Reddit, then qualifies results against a minimum engagement threshold such as 3, 5, or 10 upvotes before sending five to fifteen posts back to the dashboard.
• Webhook B is triggered per platform button. When you click YouTube Shorts, LinkedIn, Instagram, or Twitter under a post, all that post's text is sent to Webhook B for research and content generation.
• The content agent researches and enriches each topic, then returns three different angle options per chosen platform so you can pick angle one, two, or three. It also grabs an image that is emailed to you.
• Hard-coding the subreddit was chosen over auto-searching the three most popular subreddits because usually one or two subreddits are simply the best, so the extra variability was not worth it for better results.
• Adding a webhook debugger at the bottom of the Lovable 2.0 or Bolt interface is a practical hack for seeing where webhooks have gone and their status, and it can be removed once the build is proven to work.

Questions & Answers

Q: How do you build a Reddit content agent with Lovable 2.0?

You create a new Lovable 2.0 project and prompt it to build a simple Reddit content engine with three inputs: a hot, top, or new button selector, the subreddit, and the topic. The dashboard sends this to Webhook A, which returns five to fifteen posts listed three per row and expandable for heavy text. Each post shows YouTube Shorts, LinkedIn, Instagram, and Twitter logos, and pressing one sends that post's text to Webhook B. No coding is required.

Q: What three inputs does the Reddit content system need?

The system needs exactly three pieces of data. First, the sort type, chosen through a button selector for hot, top, or new posts, with top added during the build. Second, the subreddit you want to search, for example the n8n subreddit. Third, the topic or keyword, such as n8n. The creator notes that if you are ever unsure of the keyword, you should just put the main keyword because it usually appears in most posts.

Q: Why does the creator use Reddit to find content ideas?

Reddit is used because if someone went to Reddit to post something, the issue was enough of a problem that they took action, and high engagement through upvotes signals a topic of interest. The creator gives a real example: a self-hosting n8n video went mini viral on Instagram, and one reason he knew it would perform was seeing the idea being very popular on Reddit first. The system lets you find what is working in your niche and turn it into content.

Q: What is the role of the two webhooks in this system?

The system uses a double webhook integration. Webhook A receives the subreddit, keyword, and sort type from the dashboard, searches Reddit, then qualifies the results against a minimum engagement threshold such as 3, 5, or 10 upvotes before sending five to fifteen posts back to the dashboard. Webhook B is triggered when you press a platform button on a post, sending all that post's text onward for research and content generation.

Q: How does the agent turn a Reddit post into social media content?

When you click a platform button such as LinkedIn, Instagram, X, or Shorts under a post, all the text in that Reddit post is sent to Webhook B. An agent then ruthlessly researches the topic and enriches it. Based on the platform you specified, it returns three different angle options so you can choose angle one, two, or three if you do not like the first. It also grabs an image that gets emailed to you.

Q: Why did the creator hard-code the subreddit instead of auto-searching?

The creator built a function that could search for the three most popular subreddits and pull the best from all three, but chose to hard-code the subreddit instead. He reasoned that for the extra two minutes of effort the results are better, because usually there are only one or two subreddits that are simply the best. He did not want that variability baked in, preferring to save time and get straight to the value.

Q: What is the webhook debugger hack mentioned in the video?

The creator recommends adding a webhook debugger at the bottom of the Lovable 2.0 or Bolt interface, describing it as very helpful. It shows where the webhooks have gone and their status, so you can see what is actually happening in the build. He includes it in the initial Lovable prompt and notes it can be removed once you have proven that everything works, keeping the final dashboard clean.

Q: What can you do with this Reddit content agent system?

The system acts like a five-figure content AI team in your business. It finds the most viral topics on Reddit based on your keywords, then transforms them at a single click into Twitter, Instagram, LinkedIn, or Shorts posts you can repurpose across platforms. You can generate images for any social platform, apply your own tone of voice, and either sell the system to businesses or use it to level up your own content, all without coding.

Summary & Key Takeaways

• The goal is a no-code AI content system that replaces a marketing team by finding viral Reddit topics from your keywords and repurposing them into Twitter, Instagram, LinkedIn, or Shorts posts. Lovable 2.0 serves as the dashboard, and it generates images for whichever social platform you target.

• The creator emphasizes that ideas drive content success, roughly 80% of it, based on talks with large creators. Reddit is used as a demand signal because posting there plus high upvotes proves a topic matters, letting you build content around what is already working in your niche.

• The build connects the Lovable dashboard to two n8n webhooks. Webhook A searches Reddit by subreddit, keyword, and sort type, qualifies posts by an upvote threshold, and returns five to fifteen results. Webhook B takes a chosen post and produces platform-specific content with three angles and an emailed image.
