When using the Discovery module in Stellar, you can filter Instagram profiles by category — helping you quickly narrow down your search to relevant influencer types.

🗂️ What are the categories based on?

The Category filter includes 28 categories, created from a broader list of 130+ specific topics we track across the platform.
This filter is currently only available for Instagram.

🔑 How does it work behind the scenes?

The Keyword Search in the Catalog looks at the influencer’s:

  • Captions

  • Bios

It detects mentions of your chosen keyword, and even uses a semantic keyword matrix to enhance relevance.
This means we also analyze:

  • Words commonly used alongside your keyword

  • Their frequency of joint use

This lets us rank influencers by true topic relevance, helping you find creators whose content and voice genuinely resonate with their audience on that subject.
