TrendSearch

TrendSearch is a tool that helps you find what people are talking about on Reddit. You can enter a few keywords and subreddits, and it shows you posts that match — sorted by time, popularity, or relevance. It also breaks down which subreddits talk about your topic the most, how much engagement each post gets (based on upvotes and comments), and whether the conversations are generally positive or negative.

If you're building a product, writing content, or just trying to understand what a community cares about, TrendSearch makes it easier to spot useful trends. You can save your searches and download results.It’s free to try with some limits, and if you need more, you can upgrade.
