Topic Discovery

How Screvi's AI discovers thematic topics across your highlight library

What is Topic Discovery?

Topic Discovery uses AI to analyze your entire highlight library and identify thematic clusters: groups of highlights that share common themes, even when they come from completely different books and sources.

How to Use It

In the web app:

  1. Go to the Feed page
  2. Open the "Discover Topics" option

In the mobile app:

  1. Go to the Search tab
  2. Use the Topic Discovery feature

What You'll See

Screvi identifies between 5 and 20 topics depending on the size and diversity of your library. Each topic shows:

  • A descriptive label (generated by AI)
  • The number of highlights in that topic cluster
  • A preview of representative highlights

Tap/click a topic to see all highlights grouped under that theme.

How It Works

  1. Screvi uses the AI embeddings (vector representations) of all your highlights
  2. These embeddings are clustered using semantic similarity algorithms
  3. The resulting clusters are labeled by AI to give each topic a meaningful name
  4. Topics are cached for performance and can be refreshed when your library grows

Why It's Useful

  • Discover hidden connections: Find that your highlights about psychology, philosophy, and business strategy all converge on the theme of "decision-making under uncertainty"
  • Explore your reading themes: See what topics you gravitate toward most
  • Create focused review sessions: Browse highlights by topic to deepen your understanding of a specific theme
  • Find gaps: Notice which topics have few highlights and consider reading more in those areas
