How PlotForge Works
From blank page to polished manuscript in three clear steps. Work manually, use AI assistance, or combine both; PlotForge adapts to your workflow.
Outline
Build your story structure manually with professional templates, or use AI to generate a complete outline. Apply proven structures like 3-Act, Hero's Journey, or Save the Cat, then customize every beat.
Draft
Write chapters yourself or use optional AI assistance. Organize with cross-references, track character relationships, build detailed worldbuilding, and visualize your timeline, all in one workspace.
Refine
Polish your manuscript with professional organization tools. Track consistency across characters, plot, and world. Use Scene Surgery for targeted AI improvements, or refine everything manually.
All three steps happen in one unified workspace
