The narrative knowledge graph for the AI era

Knibu turns stories into structured, queryable knowledge.

We transform films, TV series, manga, and novels into a temporally-aware narrative knowledge graph — so fans can revisit any story with confidence, creators can design with structure, and AI agents can retrieve reliable narrative context.

Knibu for iOS — unedited screen capture

A narrated walkthrough of the app: browsing a story's events on a timeline, opening what each moment changed, reading relationships as they shift, and building a query step by step.

A walk through the app

Real captures from the Knibu iOS build, which runs today in limited access — used internally and by invited testers while we finish the remaining surfaces ahead of a public release.

Nothing in Knibu is a written article. Every screen below is a query: a set of conditions run against the graph and drawn in a chosen form. Change a condition and the same screen answers a different question. Save it and it becomes a card someone else can open and keep pivoting on — that is what a post on Knibu actually is. The nine views below are independent tools, not steps in a flow.

01

Events on a timeline, and in place

Events lay out by when they happened and where. Each one carries the change it caused — who gained what, who moved, what was destroyed — so a plot reads as a structure instead of a summary.

02

Plot at whatever depth you want

Detail level is a control, not a fixed property of the record. Step up a level and whole arcs collapse into single entries — a thousand-episode series stays browsable end to end, then opens back up exactly where it matters.

Stepping up a level; arcs collapse

03

Prepared views you just open

Reading a work yourself is one way in. The other is to open a view someone already assembled — its query has already run, so you land on the finished picture rather than a search box. What a view can be built from isn't constrained; this one happens to be a complete timeline drawn around a single object.

Zooming and panning a prepared view

04

What each moment changed

Open an event and it resolves into the specific things it moved: identities, relationships, possessions, affiliations — each attributed to the character it belongs to.

05

Relationships, and how they shift

Relationships are typed and time-bound. Drag the timeline and the edges redraw for that moment, instead of collapsing a whole story into one flat summary.

Dragging the timeline; edges redraw

06

Organizations across time

A hierarchy is data too: which posts exist, who holds each one, and when it changed hands. Move to a different era and the chart repopulates with whoever held those posts then.

Changing era; post-holders swap

07

Several characters, one shared clock

Put characters side by side against the same axis and their affiliations, abilities and status can be compared decade by decade rather than read one biography at a time.

Stepping across four character tracks

08

Search across every facet

Filter by language, genre, theme, release window and box office. Results come back as a graph you can keep pivoting on, not a list that ends the conversation.

Adjusting filters; results respond

09

Re-measure the result by anything

Bind a numeric attribute — here, box office — to node size, and the shape of a whole result set becomes readable at a glance.

Why now

Why narrative needs structure

Long-running IPs have a memory problem

When a sequel arrives years later, audiences struggle to recall what happened. The barrier to re-entry hurts engagement and box-office returns.

Creators work in unstructured prose

Maintaining continuity, character arcs, and timeline logic across a large story is hard — and getting harder as stories grow.

AI agents lack reliable narrative grounding

General models hallucinate plot details; web search returns noisy, inconsistent results. There's no trustworthy, structured source of narrative truth.

The product

One knowledge graph, three ways to use it

The same temporally-aware engine, surfaced for three audiences.

For fans

Knibu App

Catch up on the stories you love, before the next chapter drops.

  • Ask any question about a story in natural language and get reliable, source-grounded answers with visual explanations.
  • Browse events, characters, and relationships as they change across the story's timeline.
  • Generate shareable visual summaries to discuss key moments with your community.
Limited access

For creators

Knibu Studio

Build your story as a structure, not just a document.

  • Design characters, events, and timelines on a visual canvas with AI assistance.
  • Reference and analyze how existing works handle similar arcs, beats, and structures.
  • Collaborate with co-writers and export structured work to manuscript form.
In development

For developers & AI agents

Knibu API / MCP

Reliable, time-aware narrative context for AI agents.

  • Query structured narrative facts — events, character states, relationships, timeline-anchored details — via a simple API.
  • Connect through the Model Context Protocol (MCP) so any AI agent can access narrative knowledge as a tool.
  • Built for grounding: structured graph retrieval for discrete facts, semantic search for abstract concepts.

How it works

How Knibu works

01 / Ingest

From story to data

We process story content into structured narrative data: events, entities, relationships, and their changes over time.

02 / Structure

Into a temporal graph

Information is organized into a temporally-aware knowledge graph that preserves internal logic and consistency.

03 / Access

Out as answers

Users query in natural language; the system retrieves the right facts and presents them through clear, purpose-built views — or serves them to AI agents via API.

The complexity lives in the graph; the experience stays simple.

Built for scale

Knibu runs an AI-intensive, cloud-native stack. Large language models do the work of turning narrative information into structured, time-aware graph data, and the graph itself is hosted on managed cloud infrastructure. Our compute curve is driven by what comes next: opening the app to the public, serving real-time queries to fans, creators, and AI agents, and running AI-driven natural-language query across the graph. Cloud compute and managed AI services are central to that.
