Questions
What's the main difference between Authr and Squibler?
Squibler generates whole books and screenplays from an idea, with covers, images and translation on top. Authr is built the other way round: you write, and agents draft, review and edit alongside you, with every change to your prose waiting for approval.
Can Authr write a whole book?
Agents can draft as much as you ask, scene by scene, from your outline. Authr is designed so you review and steer that work rather than receive a finished book.
Is Authr free?
Yes. The Free plan covers your first book with every writing tool and about 15 agent tasks a month. Pro is $19 a month and Studio $49.
