How to Find the Right Subreddits

Reddit has over 100,000 active communities, and finding the right ones for your topic can be overwhelming. Reddit's built-in search helps, but it often surfaces inactive or barely relevant communities. Our subreddit finder uses AI to match your topic against Reddit's community landscape and suggest the communities where your target audience is actually having conversations.

The tool returns three types of information for each subreddit:

Why Subreddit Discovery Matters

The subreddits you monitor determine the quality of insights you extract. Choose the wrong communities and you get noise. Choose the right ones and you get a constant stream of unfiltered customer opinions, product comparisons, feature requests, and competitive intelligence. The difference between good and bad Reddit research almost always comes down to which subreddits you are watching.

For Market Researchers

Market research on Reddit starts with identifying where your target customers spend their time. A B2B SaaS company researching project management needs to look beyond r/projectmanagement. Their customers might also be active in r/startups, r/sysadmin, r/devops, or r/consulting. Each community reveals different aspects of customer needs and preferences. Our finder surfaces these non-obvious connections.

For Product Managers

Product managers use subreddit discovery to find where users discuss their product category. The goal is to find communities where people naturally talk about the problems your product solves, not just communities about your industry in general. The more specific and relevant the subreddit, the more actionable the feedback.

For Content Marketers

Content marketers use Reddit as a source of content ideas and audience research. Finding the right subreddits means finding where your audience asks questions, shares frustrations, and looks for recommendations. These discussions reveal exactly what content your audience wants, in their own words.

For Competitive Intelligence

Competitor analysis on Reddit is most effective when you know which subreddits feature product comparison discussions. Communities like r/selfhosted, r/webdev, or industry-specific subreddits often have detailed comparison threads where users discuss the pros and cons of competing products. Finding these communities gives you direct access to honest competitive feedback.

From Discovery to Analysis

Finding the right subreddits is step one. The real value comes from systematically analyzing the discussions happening in those communities. Reddily helps you go from discovery to actionable insights: analyze individual threads for pain points, feature requests, sentiment, and competitive mentions, or run batch analysis across multiple threads to identify patterns.
