+# Phase 20 -- Story Intelligence User Experience
+
+## Purpose
+
+This document defines the intended user experience for Story
+Intelligence.
+
+It complements the technical architecture documents by describing how
+Story Intelligence should feel from an author's perspective.
+
+The goal is not simply to import a manuscript into PlotDirector.
+
+The goal is to transform an existing manuscript into a rich, structured
+PlotDirector project with the minimum possible effort from the author.
+
+Throughout this document the author remains the final authority.
+
+Story Intelligence assists the author.
+
+It never replaces them.
+
+------------------------------------------------------------------------
+
+# Design Philosophy
+
+Story Intelligence should feel effortless.
+
+The author should never feel that they are performing data entry simply
+so PlotDirector can understand their manuscript.
+
+Instead, PlotDirector should quietly perform hours of structured work on
+the author's behalf.
+
+The author should feel that they have handed PlotDirector their
+manuscript and, after a short wait, received a populated writing project
+ready to explore.
+
+The ideal experience is:
+
+> "Upload my manuscript. Make a cup of tea. Come back to a project that
+> already knows my story."
+
+------------------------------------------------------------------------
+
+# Core Principles
+
+## The manuscript is the source of truth.
+
+Story Intelligence never rewrites the author's work. It observes,
+organises and suggests. The original manuscript always remains the
+authoritative version of the story.
+
+## AI assists.
+
+AI never decides. Every imported item is a suggestion. The author may
+change, merge, split or delete anything created during import.
+
+## Structure before detail.
+
+Before PlotDirector can understand a story it must understand its
+structure. Story Intelligence therefore builds the structural framework
+first before extracting detailed information.
+
+## Review uncertainty, not certainty.
+
+Authors should never be asked to review hundreds of AI decisions. Only
+items with low confidence should be highlighted.
+
+## Creativity should never be interrupted.
+
+Story Intelligence performs its work in the background. It should never
+repeatedly stop the author to request approval.
+
+# Import Modes
+
+## Automatic Import (Recommended)
+
+The author supplies a manuscript and PlotDirector performs the complete
+Story Intelligence pipeline automatically. No manual approval is
+required during import.
+
+## Guided Import
+
+Guided Import performs the same analysis pipeline but pauses at selected
+stages to allow the author to review AI suggestions such as scene
+boundaries, character aliases, ambiguous locations and low-confidence
+relationships.
+
+# Story Intelligence Pipeline
+
+## Stage One -- Structural Analysis
+
+Outputs include chapters, suggested scene boundaries, narrative
+structure, point-of-view changes and significant time shifts.
+
+## Stage Two -- Semantic Analysis
+
+Outputs include scene summaries, characters, locations, assets,
+relationships, knowledge changes, timeline clues, questions, story
+metrics and structured observations.
+
+# Progress Experience
+
+During processing PlotDirector should continuously communicate progress
+using friendly, reassuring messages such as:
+
+-   Reading Chapter 12...
+-   Identifying dramatic scene changes...
+-   Building character profiles...
+-   Discovering important locations...
+-   Tracking significant story objects...
+-   Connecting relationships...
+-   Analysing emotional pacing...
+-   Mapping timeline events...
+-   Checking story continuity...
+-   Finalising your project...
+
+# Import Completion
+
+Rather than simply stating that the import has finished, PlotDirector
+should summarise what has been created.
+
+Example:
+
+-   [x] 47 Chapters
+-   [x] 183 Scenes
+-   [x] 64 Characters
+-   [x] 29 Locations
+-   [x] 17 Story Assets
+-   [x] Timeline created
+-   [x] Story metrics generated
+
+# Import Report
+
+The Import Report should highlight only lower-confidence items, such as
+large scenes, possible aliases, ambiguous locations, low-confidence
+relationships and scene boundaries requiring review.
+
+# Confidence Philosophy
+
+Confidence guides review effort. It should never prevent import.
+
+# Author Review
+
+Review is always optional. Authors can begin using PlotDirector
+immediately after import and refine imported data over time.
+
+# Future Improvements
+
+Future capabilities may include additional AI providers, improved
+prompts, better scene boundary detection, richer continuity analysis,
+story health reports, character journey analysis and conversational "Ask
+My Story" features.
+
+# Success Criteria
+
+Story Intelligence succeeds when:
+
+-   A first-time user can import an existing manuscript without prior
+    PlotDirector knowledge.
+-   The resulting project immediately feels recognisable as their own
+    book.
+-   Manual setup has largely disappeared.
+-   Review effort focuses only on uncertainty.
+-   The author remains in complete creative control.
+-   PlotDirector saves hours of repetitive project setup.
+
+# Guiding Principle
+
+Story Intelligence should never interrupt creativity.
+
+It should quietly perform hours of structured work while the author
+makes a cup of tea.
+
+When the author returns, PlotDirector should already understand the
+structure of their story.
