How to Automate Reddit Brand Insights?

Scan Reddit for posts that matter to your brand and turn them into clear, short insights. Great for marketing and community teams that want quick context without reading every thread.

The flow runs on a manual start. It searches Reddit for a chosen keyword, then keeps only posts with at least five upvotes, written in the last seven days, and with real text. The text is trimmed to the first 500 characters to keep it focused. OpenAI gives a one sentence summary and a simple Yes or No label to confirm if the post is truly about your product. Merge and Set nodes join the AI results with Reddit data and output neat fields like title, subreddit, upvotes, subscriber size, summary, and the Yes or No tag. A backup summary step kicks in if the classifier returns No, so you still get context.

Setup needs Reddit and OpenAI accounts. Expect faster brand checks and earlier responses to important threads. Common uses include brand monitoring, content ideas, and a quick screen for outreach leads. Change the keyword to watch competitors or product features. The simple structure makes it easy to extend later with more sources or a scheduler if needed.

How do you set it up?

  1. Import the template into n8n: Create a new workflow in n8n > Click the three dots menu > Select 'Import from File' > Choose the downloaded JSON file.
  2. You'll need accounts with Reddit and OpenAI. See the Tools Required section above for links to create accounts with these services.
  3. Open the Reddit node in n8n and create a new credential. In the 'Credential to connect with' dropdown, click 'Create new credential' and follow the on screen steps to connect your Reddit account. Name the credential so your team can recognize it later.
  4. In the Reddit node, set Operation to Search, Location to All, and the keyword you want to track. Keep Sort as New to focus on fresh posts.
  5. Open the IF node and confirm three checks: upvotes greater than or equal to 5, selftext is not empty, and created in the last 7 days. Adjust these to match your monitoring rules.
  6. Open the Set node and confirm a field that trims the post text to about 500 characters. If needed, add a new field that takes the first 500 characters of the post body.
  7. Create OpenAI credentials in the n8n credentials manager. Choose OpenAI API, paste your API key from your OpenAI account, and save. Use clear names for credentials.
  8. Open the OpenAI Summary node and keep temperature low, such as 0.3. Make sure the instruction asks for a one sentence summary under 20 words.
  9. Open the OpenAI Classify node and confirm the prompt asks for a Yes or No answer about whether the post is about your product. If outputs are incomplete, raise the max tokens value.
  10. Click Execute Workflow. Check the SetFinal node output. You should see subreddit, title, upvotes, subscriber size, summary, and a Yes or No label. If you get no items, relax the filters or try a broader keyword. If OpenAI errors appear, verify the API key and usage limits.
