The Observatory

Pages that turn themselves.

A page that looks like a book. When it fills, the next one begins on its own.

Novly on a Mac: the chapter list on the left, the page ‘The Observatory’ in the middle, and the AI Assistant with the book’s context on the right.
The Atlas of Small Lights, a sample book, open in Novly.

Your story, as a sky.

Characters are stars, places are landmarks. Press play and the book lights up, chapter by chapter.

The Story Map's constellation for The Atlas of Small Lights: characters as glowing stars joined by relationship lines, places as landmarks, a continuity panel on the left and Mara Venn's card on the right with her mentions per chapter and connections. The Story Map's storylines: each character is a coloured thread moving between the Observatory, Venn and Daughter, the Tide Archive and Saltglass Point across six chapters, bundling where characters meet.

Continuity notes, worked out from your words. No AI needed.

  • Where did Ivo Bell go?Last seen three chapters ago. Bring him back, or tell the reader why.
  • Wren and Odile never share a scene.They’re allies, but no chapter has them together yet.
  • The Lamplighter arrives late.A hint earlier would make the entrance feel earned.

Words and pictures.

Lewis Carroll wrote Alice by hand and drew her himself. Novly keeps both kinds of book.

Novels get chapters and pages that break on their own. Picture books get an 800 by 600 canvas where text and illustration share the page, with pictures from Image Playground on your Mac.

Lewis Carroll's handwritten manuscript of Alice's Adventures Under Ground, page 33: the White Rabbit, drawn in ink, scolds Alice beside the text.

Before chapter one.

Yes. Novly has no subscription, credits or writing limits. If you connect a cloud AI provider, that provider bills your own account directly.

An Apple silicon Mac with macOS 26 or later. Apple Intelligence also depends on your device, language and region; local models and cloud AI work without it.

No. Everything about writing works without it. When you want help, choose Apple Intelligence, an open model on your Mac, Ollama, or a cloud provider you connect.

Your library is one file on your Mac. With on-device AI nothing leaves it. If you choose a cloud AI, the prompt and story context for that request go to that provider, under its terms.
