How Logos works
Step 1
Create a project
Start a new story project in seconds. Logos scaffolds the initial structure so your canon, manuscript, and supporting material already have a place to live.
Step 2
Shape your canon
Refine the rules, documents, and core truths of your story world in one dedicated layer. Your canon stays clean, explicit, and easy to verify.
Step 3
Write your chapters
Draft chapters in a focused writing workspace that keeps the manuscript, scene context, and project navigation close together.
Step 4
Use AI capabilities
Generate short next-scene directions from the saved chapter and Story Spine, review continuity against canon, preview reversible chapter polish, inspect structural and pacing diagnostics, and add or review chapter illustrations without leaving the manuscript flow.
Step 5
Map your entities
Manage characters, places, creatures, factions, and objects as structured records linked to the scenes where they matter.
Step 6
Visualize connections
Explore how people, places, and plot threads interact through a connected relationship view. Weak links and missing context become visible before they derail the draft.
Step 7
Export your manuscript
Prepare your work in manuscript-ready formats and leave the platform with clean output. Export to DOCX, PDF, or plain text when you are ready to move forward.

Why Logos is different
Your canon is the foundation, not a sidebar.
Logos organizes your story world through structured documents, lore entries, and continuity layers. The source of truth stays explicit, reviewable, and connected to the manuscript.
Navigate relationships instantly with the Affinity Chart.
The relationship graph shows how characters, places, and threads connect across the project. You spend less time hunting through notes and more time fixing real narrative issues.
AI that works from your canon, not generic guesses.
When you use AI features, the model works from the lore and rules you have built. That keeps support contextual while leaving authorship and decisions with you.
Export a clean manuscript when the draft is ready.
Logos is designed to get work out as well as in. When it is time to share, edit, or submit, you can export without rebuilding formatting by hand.

Questions about Logos
Final questions should not force a detour into support docs. These are the practical points that usually decide whether someone signs up.
No. Logos works first as a structured writing system. AI is optional, and you can use the planning, canon, and drafting tools without relying on it.
