Overview

After shipping several Chrome extensions I kept asking the same question before each new one: is this niche already crowded? ChromeNiche answers it in seconds. Describe an idea, and the service searches a continuously synced index of the whole Chrome Web Store, scores the niche on six dimensions (competition, install counts, ratings, demand signals and more) and returns an honest verdict: BUILD, TEST or SKIP, with AI-written reasoning and next steps. A Discover mode fans out broad queries to surface underserved niches. The data pipeline runs weekly on GitHub Actions with semantic search over vector embeddings, and there is a companion Chrome extension that shows the verdict right on any store listing.
