How to Use Fiction Forge
Welcome to the ultimate AI novel-writing engine. Follow the 6 phases to build your masterpiece.
Phase 1: The Spark
Define your genre, word count, and premise. The engine will dynamically interview you about the world based on your initial prompt.
Phase 2: Character Forge
Cast sizes scale automatically. We generate psychological profiles, MBTI traits, and can paint visual portraits via the Flux model.
Phase 3: Worldbuilder
Using the 4-tier Iceberg theory, we establish Surface, Shallows, Deep, Abyss plot subtexts to give your story dimension.
Phase 4: Architect
Fractal outlining maps a 7-point skeleton, calculates chapter counts, and mathematically divides the story into micro-beats.
Phase 5: The Forge
The infinite ghostwriter loop. The engine feeds on your outline tracker and rolling memory cache to write seamlessly. Let it run!
Phase 6: The Bindery
Generate a title, blurb, and AI cover art. Finally, hit Export to dynamically compile the entire manuscript into print-ready PDF format.
v5.2 - The Feedback Memory Cache
AUTHOR CORRECTION CACHE: Added a persistent feedback loop in Phase 5. Authors can input global rules (e.g., "Stop making characters smirk") which are stored in the state manager and injected as absolute commands in every subsequent ghostwriter prompt.
v5.1 - The Global Steering & Auditing Update
GLOBAL STEERING AXES: Added live, hot-swappable dials in Phase 5 to dynamically control Tone, Action, Stakes, and Pacing. The active states are injected into the context of every single beat generated.
PROSE AUDITOR & RED PEN PASS: Implemented a $00 cost JavaScript regex auditor that intercepts generated prose and detects adverb clusters, repetitive sentence starters, and monotonous pacing. Flawed beats trigger a silent "Red Pen" rewrite using the fastest logic model to automatically repair the prose before inserting it into the manuscript.
CREATIVE DNA INTERVIEW: Replaced blank input fields in Phase 1 with an active binary/trinary questioning system that forces authors to build tension and friction into their premise.
v5.0 - Strict Curation & Matrix Overhaul
STRICT CURATION ARCHITECTURE: Replaced dynamic/fuzzy credit-bucket sorting with a strict, hardcoded agent matrix. Prevents "clever" fallback overrides that obscured which AI models were actually firing.
ZERO CREDIT ENFORCEMENT: Draft Tier is now mathematically locked entirely to $00 cost agents. If no free model is available, the engine safely halts instead of silently charging credits.
MASTERWORK HONESTY: Removed logic that secretly downgraded outlining tasks on the Masterwork tier. If you pick Masterwork, you get Claude Sonnet for every single task, no exceptions.
v4.7 - The Vibe Switch & Agent Routing
VIBE SWITCH ARCHITECTURE: Added a user-facing toggle that masks complex model routing. "Standard" uses Gemini 3.0 Flash for clever plotting. "Edgy" routes to Grok 4.1 Fast for dark, anti-trope narratives.
THE WORKER BEE HANDOFF: Restricted Gemma 4 31B purely to Phase 5 prose generation. Since it no longer handles JSON logic, generation lag is cured while preserving masterwork-tier prose quality.
PARALLEL EXECUTION: Optimized The Bindery and Character Forge with concurrent execution, drastically reducing wait times.
v3.0 - The Brutal Truth Pacing Overhaul
MATH CALIBRATION: Massively reduced word-count padding targets (e.g., from 750 down to ~450 for Premium) per beat to accurately map to human action boundaries, saving tokens and improving pacing.
POSITIVE FORMULAS: Added explicit positive constraints for "The 80/20 Rule", "In Media Res", and "Declarative Action" to eliminate internal monologue, inventory checks, and over-explaining gestures.
EXTERNALIZED EMOTION: Replaced tone planning with "Externalized Emotion" in the <plan> block, forcing the AI to lock in physical manifestations of feelings before generating prose.
v2.1 - Manuscript Completion UI Update
PERSISTENT UI STATE: The Forge tab now detects when `completedBeatsCount` equals `flatBeats.length` and permanently morphs the writing button into a disabled green "Manuscript Complete" state.
v2.0 - The Prose Execution & Agency Update
POSITIVE FORMULAS: Swapped negative bans (e.g., "don't use filter words") for positive formulas ("Direct Camera Rule: Remove the observer"). This prevents Mid-Tier models from hyper-fixating on banned concepts.
AGENCY-FORCED OUTLINING: Rewrote the Phase 4 Architect instructions so every single beat is formatted around a protagonist's tactical choice, ensuring the writer never receives a passive scene prompt.
WEAPONIZED DIALOGUE: Banned characters from explaining the world to each other. They must use dialogue to manipulate, attack, or hide information.
v1.9 - The Red Pen Optimizations
DEEP POV LOCKDOWN: Forced the model to respect physical limitations of the POV character (e.g., if deaf, no sound descriptions).
FILTER WORD BAN: Banned lazy writing crutches ("saw", "felt", "heard", "noticed") to enforce showing over telling.
ACTION CHOREOGRAPHY: Banned summarizing conflict. AI must describe physics, momentum, and visceral impact.
v1.8 - The Micro-Anchor & JIT Planning
MICRO-ANCHOR (CONTEXT DIET): Severely truncated the prose-feeding memory window from ~600 words to just ~60 words. This strictly confines the LLM to the immediate physical present, entirely destroying the "echo chamber" loop of atmospheric bloat and forcing relentless, fast-paced action.
DYNAMIC CAST CONSTRAINTS: The engine now pre-parses upcoming beats to identify active characters in the scene. It weaponizes their stored Phase 2 profiles (Flaws, MBTI, Motivations) directly into the prompt as hard constraints, injecting natural friction into character dialogue and interactions.
JUST-IN-TIME (JIT) PLANNING: Added a forced Chain-of-Thought <plan> block execution prior to generating prose. The ghostwriter must explicitly define the POV, unspoken conflict, and physical action anchors before writing, structurally eliminating purple prose and internal monologue loops.
v1.7 - Smart Cache & Pro Bindery
SMART CACHE (ROLLING MEMORY): Architect engine now maps dynamic inventory, active subplots, and physical injury status on a chapter-by-chapter level, passing this memory directly to the Worker Bee prose prompt to eliminate AI amnesia.
PRO BINDERY PDF: Rewrote the export compiler to generate a professional Title Page, Copyright & Disclaimer page, and a dynamic Table of Contents before the main manuscript.
MANUSCRIPT TYPOGRAPHY: Standardized print layout, automatically dropping the text-indent on the first paragraph of every chapter while enforcing perfect justification for the remainder.
v1.6 - Context Diet & Worker Bees
CONTEXT DIET: Severely truncated the rolling memory context window to 150-600 words depending on tier. Prevents AI from falling into the "recap trap" and dramatically reduces input token costs.
DENSE BEAT ARCHITECTURE: Increased standard beats to 4 per chapter but reduced the ceiling per beat (e.g., 600 words). Creates vastly superior pacing, eliminates purple prose padding, and saves output tokens.
WORKER BEE ROUTING: Premium logic strictly routes to Claude 4.6 Sonnet / Gemini 3.1 Pro, but outsources raw prose execution to Gemini 2.5 Flash / Grok 4.1 Fast, effectively dropping the Masterwork cost by up to 85%.
v1.5 - The Co-Writer (Mid Tier) Overhaul
MATH CALIBRATION: Scaled Mid Tier pacing down from 1,000 words/beat to 800 words/beat (2,500 words per chapter). This aligns perfectly with the natural output limitations of rapid models like Haiku and Flash, eliminating prose padding and rambling.
CLAUDE HAIKU PROMOTION: DeepSeek V3 was still handling structural logic for the Mid Tier, risking the same timeouts. Claude 3.5 Haiku has been promoted to the primary structural brain for Mid Tier due to text reasoning speed.
v1.4 - The Gemini Flash Promotion
MATH CALIBRATION: Adjusted Premium tier chapter calculations to estimate 3,400 words per chapter. This corrects a pacing bug where the engine would over-generate text.
