Fantasy Writer · Your world. Your words.
Write your fantasy book with AI grounded in your lore.
Keep your characters, worldbuilding and chapters together. Get AI assistance that draws on your lore, while you stay in control of the story.
Free plan. No expiry. Export on every plan.
Your story, imagined. A cinematic dragon flight, with real editor components and fictional content.
One rule. A hundred consequences.
Your world has rules.
Your next chapter should remember them.
A lantern that only glows near running water. A character who cannot cross a border. The detail you established three chapters ago. Keep that context close as your story grows.
In your lore
“The silver lantern glows only near running water.”
In your draft
“In the dry desert, her lantern blazed.”
A detail worth questioning. A change only you can decide.
Fictional example. AI suggestions need your review.
The story behind the sentence
A dragon is a beginning.
Make it your dragon.
The scars. The loyalties. The rules of magic. Give your world details that matter, then bring that context into your writing.
Character · In your lore
Kael
He wears his father’s bronze armour. He has sworn to defend the mountain gates, even against his own brother.
A motivation that gives the action meaning.
What that could mean on the page
He flew toward the fortress.
“His father’s armour weighed against his ribs. Somewhere beyond those walls, his brother was waiting. Kael turned Ashwing toward the gates anyway.”
Family, loyalty and a promise — carried into the scene.
Your lore gives AI context. You decide what belongs in the book.

Your draft · Chapter 12
The wind died. Serin closed her right eye and aimed with her left, the arrow steady on the gate.

Lost her left eye at the Siege of Talor. Wears a plain leather patch; sights with her right.
Three weeks under Ember banners. Ended when the east gate fell — and with it, half of Serin's company.
Signed in the ruin of Talor. Its terms are why Serin no longer answers to the Watch.
Your lore says Serin lost her left eye at the Siege of Talor.
Grounded rewrite
The wind died. Serin sighted along the shaft with her right eye, the leather patch cold against her cheek, and held until the gate stopped moving.
