The Codex: your narrative universe, centralized
Characters, locations, events, universe rules — Plumora's Codex gathers everything that makes your story. AI consults it with every generation to guarantee your narrative's consistency.
Create my Codex for freeWhy every author needs a Codex
A novel is a complex structure. Dozens of characters, multiple locations, a chronology that sometimes spans years. Without a centralized reference system, inconsistencies accumulate: a character whose eye color changes at chapter 15, a location described differently in two places, a timeline that doesn't hold up.
Traditionally, authors use paper cards, spreadsheets, or scattered documents. The problem: these tools aren't connected to your text editor. You must manually verify every detail, and AI has no access to this information.
Plumora's Codex changes the game. Integrated directly into the editor, it serves as the single source of truth for your narrative universe — and AI consults it automatically.

What's in the Codex?
Characters
Create detailed sheets for each character in your novel. Physical traits, personality, deep motivations, relationships with other characters, speech patterns, personal history.
AI consults these sheets with every text generation. When a character speaks, they speak with their own voice. When they act, their actions are consistent with their personality.
Locations
Describe each location in your universe: atmosphere, sensory details, geography, history of the place. Whether it's a Parisian cafe or a fantasy city, the Codex remembers everything.
No more contradictory descriptions. Madame Dupont's living room will always have the same red curtains, the same creaking floor, and the same lavender scent.
Events and timeline
Document key plot events and their chronology. AI verifies that events follow in a logical order and that your characters can't be in two places at the same time.
Particularly useful for complex plots, flashbacks, and non-linear narratives.
Universe rules
Writing fantasy or science fiction? Define the laws of your world: magic system, technologies, social hierarchy, geopolitics. AI will respect these rules with every generation.
If magic doesn't work at night in your universe, AI will never generate a scene where a character casts a spell at midnight.
The Codex and AI: a unique synergy
What distinguishes Plumora's Codex from a simple paper card is its deep integration with artificial intelligence. The Codex isn't a passive document — it's a living knowledge base that AI consults in real time.
Contextualized generation
When you ask AI to generate a scene, it automatically consults the Codex to know the characters present, the location, and recent events.
Inconsistency detection
The Codex serves as a reference for inconsistency detection. If your text contradicts Codex information, you're immediately alerted.
Incarnation Mode
Dialogue with your characters through Incarnation Mode. AI uses the Codex to embody each character with their personality, vocabulary, and motivations.
