How It Works
From scattered thoughts to living story
Drop
A character sketch. A plot point. A fleeting what-if. Just type it. Katha captures everything.
Connect
Agents extract characters, places, events, and relationships. Your story graph grows with every input.
Surface
Gaps in your timeline. A character who contradicts themselves. Agents find what you missed and ask the right questions.
Emerge
From scattered fragments to coherent structure. Your story takes shape over days, weeks, months.
What Katha Does
Intelligence for every layer of your story
AI that augments your craft—never replaces it.
Instant Research
Ask about a historical period, a medical procedure, a city in 1920. Vetted context, injected straight into your story’s world.
Character Memory
Every character’s arc, voice, backstory, and relationships—tracked across your entire manuscript. Forty characters deep, zero contradictions.
Voice Consistency
Does that line sound like your character? Agents understand voice patterns across 100,000 words and flag when someone sounds off.
Living Story Bible
Your world-building bible constructs itself. Rules, locations, timelines, lore—all connected, all consistent, all searchable.
Story Structure
See the shape of your story. Pacing analysis, act breaks, parallel threads—a bird’s-eye view that updates as you write.
Open Threads
Agents don’t just answer. They ask. Gaps, contradictions, unexplored paths—surfaced as questions for you to decide.

Why Katha
It remembers everything.
That's the difference.
Other tools give you a chat window that forgets between sessions. Katha builds a living, structured intelligence that compounds with every thought you share. Six months in, it knows your forty characters, their arcs, the timeline gaps, the foreshadowing threads.
The Story Graph
A persistent, structured map of every character, place, event, and connection. Not a chat log—a living intelligence that grows the more you use it.
Ambient Intelligence
Agents work behind the scenes—extracting, connecting, checking. You write freely. The intelligence builds in the background.
You Decide
Agents surface questions and catch contradictions. Every creative decision stays with you. Your story. Your voice. Your call.
Start with a single thought.
The best stories begin as fragments. A character name. A place. A question. Drop your first idea and watch your story graph come alive.
