What is the difference between short, medium, and long synopsis lengths for pitching?

Synopsis lengths vary to serve different submission needs: shorter options tease the premise without fully spoiling the resolution, while medium and long formats detail story arcs and key turning points for editor refreshes.

How do I write back cover copy from an existing book manuscript?

Write back cover copy by running the summarization process on your available manuscript sections. It emphasizes the premise and story arcs to produce an audience-ready summary designed for back-cover materials.

Can I create a plot-focused summary if only some chapters of my manuscript are available?

You can create a plot-focused summary using whatever chapters are currently available. The Skill uses manuscript-aware summarization to distill existing sections into a coherent story summary for pitching purposes.

How are generated synopses saved and organized for future collaborator refreshes?

Generated synopses are saved directly to a dated synopsis file. This ensures you have organized, version-tracked summaries ready for collaborator or editor refresh needs during the publishing process.
