Chapter 3 · The Dungeon
Grace moved through the corridor, her torch casting long shadows on the stone walls. She'd been here before — or somewhere like it. The smell of damp earth and old iron…

Scene intelligence

Every scene.
Analysed.

PlotSmith reads each scene and extracts the essentials — who has the POV, what they want, what opposes them, and how it resolves. A tension score from 1–10 is plotted across all your scenes, showing your story's emotional arc at a glance.

✓POV, goal, conflict, outcome — extracted automatically
✓Tension pacing graph — see flat sections and escalation
✓Story structure mapping — scenes placed in 3-act framework
✓Weakness flags — "no conflict," "repeats prior beat," "no change"
Character profiles

A character bible that
builds itself.

Every character PlotSmith encounters in your writing gets a profile — role, traits, voice fingerprint, speech patterns, goals, and arc. The more you write, the richer it becomes.

◉
Grace Morrow
Protagonist
External goal
Reclaim her family name
Voice fingerprint
Short declarative sentences. Never asks questions. Uses nautical metaphors.
StubbornLoyalPragmatic
◈
The Moon
Supporting
External goal
Guide Grace without being seen
Voice fingerprint
Speaks only in questions. Archaic vocabulary. Poetic rhythm.
CrypticAncientProtective
◉
GMC tracking
Internal + external goals, motivations, and conflicts. The framework professional authors use.
◈
Voice fingerprint
Speech patterns, vocabulary quirks, and dialogue habits. PlotSmith flags when a character speaks out of character.
▸
Arc regression alerts
If a character acts against their established arc direction, PlotSmith flags it with the exact excerpt.
✦
Custom character sheets
Add age, gender, physical description, backstory, biggest flaw, behavior patterns — all used to improve analysis accuracy.
Flags & continuity

Catch problems
before readers do.

Continuity errors. POV shifts. Tense inconsistencies. Motivation contradictions. Missing setups. PlotSmith tracks causality — not just what happened, but whether it was earned.

✓Continuity flags — character, timeline, logic, setting, objects
✓POV and tense shifts — detected and flagged with excerpts
✓Causality engine — "this event has no setup," "this decision contradicts prior motivation"
✓World rules enforcement — define your magic system; violations are flagged automatically
✓Click to jump — every flag links directly to the passage in your manuscript
Flags · 3 issues
POV shift · Major
Grace's internal monologue breaks third-person limited narration established in chapter 1.
"I knew this was wrong" — should be "She knew…"
Causality · Setup missing
Grace uses a lock-picking skill that has no prior establishment in the narrative.
"She had the lock open in seconds…"
Voice · Minor
The Moon uses a direct imperative sentence — atypical of their established pattern of only asking questions.
Writing craft

Not grammar.
Higher level.

PlotSmith analyses for the things professional editors actually look for — not spelling mistakes, but structural and stylistic issues that weaken your prose.

✓On-the-nose dialogue — emotion stated instead of implied
✓Passive voice overuse — with specific examples
✓Weak verb suggestions — "was walking → strode"
✓Filler phrase detection — what can be cut without losing meaning
✓Writing quality score — 1–10, with specific issues itemised

med
boredom risk
On-the-nose: "She felt afraid" — show the fear instead
Passive: "The door was opened by Grace"
Weak verb: "was moving quickly" → sprinted
Filler: "She began to realize that…" — cut "began to"
Beta reader: reader may be confused why the guard didn't hear the door. 3 new concepts introduced in one paragraph.
For fantasy & sci-fi writers

Define your rules.
PlotSmith enforces them.

Define your magic system, technology limits, and world constraints. Every analysis will check for violations automatically. No more "this breaks my own rules" moments 40,000 words in.

⚡
Magic system
Describe the rules — cost, limits, who can use it, how it is learned. PlotSmith will flag any character who uses it incorrectly.
🔬
Technology limits
In a low-tech world, characters cannot suddenly use tools that do not exist. Define what is possible — violations are flagged as logic errors.
📜
Custom rules
One rule per line. "Dragons cannot enter cities built before 400 AC." "The treaty prevents mind-magic north of the river." Defined once, enforced always.
