Outline your way through the chaos

Writing’s a whole lot easier when you’ve got a plan.

Storiis’ advanced story plotting, planning and analysis tools let you write with the confidence of someone who knows exactly where they’re going and how to get there.

Drop some beats

Create multiple storylines, each with their own dramatic questions, stakes, goals, core characters and beats, then track their progress throughout your story.

Design your Narrative

Build scenes with all the elements and beats that move your story. Track character journeys, motivations, actions and more for each scene. Specify the exposition that must be told and the locations where it’s all set.

Check your timing

See how your story’s narrative plays out chronologically. Find timing-related plotholes, spot impossible travel times, make sure your story’s timing stays consistent.

Bring it all together

A visual map of your story’s scenes linked to when they chronologically happen lets you easily validate that you’re telling the right story at the right time.

Read it before it’s written

Read through your Plan based on your scene’s goals, entry and exit states, or use AI to generate a narrative summary of each scene, letting you quickly spot what’s working and what still needs work.
