# Insights that stay beside the page

> Summary sites pull you out of the book. BetterReads companions—Chapter Lens and related forms—sit next to the line so you can clarify names and structure without a tab spiral.

**For:** Anyone who stalls mid-classic when a name returns or a chapter densifies.

## Companion shapes

Novels get Chapter Lens. Drama and epic get forms that match the text (Stage Lens, Epic Chapter Lens). Character and theme guides link from Discover.

- Chapter companions on a growing curated set
- Character cards and theme indexes
- Ask / Explain on the line
- Guides never replace the original text

See the reading-system overview for the full stack. Start free; Scholar unlocks full companions and deeper study.

## FAQ

### Do all books have Lens?
