Character
Design
Build rich backstories, define values and flaws and explore inner conflicts using modern storytelling frameworks that help you spark tension and growth.
With Neptune's Layout Designer, you can fully customise character attributes to suit your process — so whether you're tracking arcs or cataloguing quirks, your characters are built your way.
World Building
Build a world your audience can get lost in.
With Neptune's powerful world-building tools, you can define rich locations, customise the attributes that matter to your story, and create immersive mood boards for every setting. Design a world map and add interactive drop-pins to track where everything happens — from quiet cafés to sprawling kingdoms.
It's visual, flexible, and built for creators who want their worlds to feel real.
Plotting
Here's where your story takes shape.
Start with high-level beats, then expand them into rich, meaningful scenes filled with character, conflict and momentum. Rearrange and refine your sequence until the pacing feels just right.
This is the backbone of your narrative — flexible, powerful, and entirely yours.
Writing
Whether you’re writing a novel or a screenplay, Neptune’s story editor is designed to support your process — not get in the way.
It gives you everything you need at your fingertips: connected scenes, character notes, location details and real-time collaboration, all in one place. And when it’s time to tune out the noise, Focus Mode lets you retreat into a clean, minimalist writing space — just you and the page.
Storyboarding
Neptune’s storyboard tool lets you lay out your entire sequence with clarity and control. Add images, tag each shot with key details, and switch between tile view or list view depending on your workflow.
Play back your sequence to get a real feel for pacing, rhythm and visual storytelling — it’s like previewing the edit before you’ve even picked up the camera.
Collaboration
Create together, in real time.
Neptune makes collaboration seamless — invite co-writers, script advisors, directors, concept artists, or even financiers into your project. Share your work live, get feedback instantly, and keep everyone on the same page.
Control who can edit and who can view, so your story remains yours while the creative input flows.
