# Feed Discovery

> Ask your agent to discover relevant Reddit communities from any website URL

Don't know which subreddits to track? Give your agent a URL — your own site, a competitor's page, or a product in your space — and it analyzes the content to surface the Reddit communities where that audience is active.

Under the hood, this uses the same `reddit-feed-creator` skill described in [Reddit Feeds](/features/reddit-feeds). You don't invoke the skill directly; you just ask.

## How it works

Send your agent a URL with a discovery request. A few patterns that work well:

```
Analyze linear.app and find the subreddits their audience hangs out in.
Recommend 10-15 high-signal communities.
```

```
Look at our product page at example.com — which Reddit communities should
we be monitoring for our target users?
```

Your agent will:

<Steps>
  <Step title="Visit and summarize the URL">
    Extract a 2-3 sentence site description from the page content.
  </Step>

  <Step title="Identify audience personas">
    Generate 3 or more distinct user profiles likely to visit the site.
  </Step>

  <Step title="Extract keywords">
    Pull 12-18 topic, product, and pain-point keywords to seed the subreddit search.
  </Step>

  <Step title="Recommend subreddits">
    Rank subreddits by relevance and community size, filtering out oversized general-purpose communities like r/all and r/popular.
  </Step>

  <Step title="Save as a feed (optional)">
    Confirm the list with your agent and it saves them as a curated feed you can reference by name later.
  </Step>
</Steps>

## What the analysis includes

Each URL analysis produces three components that drive subreddit recommendations:

| Component             | Details                                                        |
| --------------------- | -------------------------------------------------------------- |
| **Site description**  | A 2-3 sentence summary of what the site does and who it serves |
| **Audience personas** | 3+ distinct user profiles who would visit the site             |
| **Keywords**          | 12-18 terms covering topics, products, and pain points         |

These components work together to match your site against Reddit communities where your audience is already active.

## Better results, fewer distractions

Recommendations are designed to surface communities where real conversations happen. The discovery engine automatically filters out oversized, general-purpose subreddits that add noise without value.

<Tip>
  Run discovery against multiple URLs to compare results. Try your homepage, a competitor's landing page, and a relevant blog post to build a well-rounded feed.
</Tip>

## From discovery to monitoring

Once you save a feed from the discovery results, you can reference it by name in any future conversation — e.g. *"Summarize the top posts in my indie-saas feed from this week"*.
