Where Atticus is stronger

  • Far deeper typesetting: themes, drop caps, spreads, headers and footers for print.
  • A one-time $147 with no subscription.
  • Works offline.

Where Authr is different

  • A story bible: codex, relationship graph and timeline. Atticus has none of these.

Use both

Write, revise and check the book in Authr, export DOCX, and import it into Atticus for the final interior.
