A knowledge map for decisions, documents, people, and AI

Documents survive. The reasons behind decisions don’t.

Kroma Key connects decisions, documents, people, and AI work in one knowledge map. Even when ownership changes, the reasoning stays with the organization—so people and AI don’t have to solve the same problem twice.

What is an ontology?

It is a knowledge map that connects your company's knowledge

Like a transit map connecting stations, an ontology connects decisions, documents, meetings, owners, and AI work in one map. The reasons behind decisions remain with the company when ownership changes. Individuals can also connect scattered notes and AI conversations so they can find them later.

Answer questions like these
  • Why did I choose this laptop model last year?
  • Who approved this document, and in which meeting?
  • Is that decision still valid today?
Who is it for?
Business teams (B2B) and individuals (B2C)
What does it retain?
Decision rationale, related documents, owners, and change history
How do I start?
Use the cloud or install it on company servers
What improves?
Handoffs, audit readiness, and the context available to AI

Open a decision to see everything connected to it

Each node in the graph represents a decision, document, meeting, AI analysis, or change record. Open a major decision such as the pricing policy update to see its notes, meeting records, AI analysis, and change history together.

Example questions for this graph

Ask the knowledge map

Ask about a team decision

Scope: Ontology graph

Ask in natural language, and Kroma Key finds the supporting evidence in the map. Start with one of the examples below.

How it works

Records, search, and AI automation on one graph

Records, search, audit support, and AI automation work together on the same graph instead of in separate tools.

Decision graph

Each decision becomes a node connected to documents, meetings, owners, and evidence.

Change history

Record what changed and why for handoffs and audit support.

Ontology Bot

AI organizes tags, gathers context, and proposes corrections for inconsistent records.

Context-aware AI routing

Route a question to OpenAI, Anthropic, or a local LLM. Keep sensitive work inside your environment and use external models where appropriate.

Ontology Bot

Use the ontology from chat

Connect it to messaging environments such as Slack, Discord, Telegram, and KakaoTalk. Capture decisions and their rationale where the team already works, then retrieve past decisions with supporting evidence.

  • Gather contextIdentify decisions and rationale worth retaining and organize them in the ontology.
  • Correct recordsFind inconsistent or missing records and propose corrections.

Why did we choose this pricing policy?

Ontology Bot

The team considered margin and competitor positioning. Here are the related meeting and supporting documents.

Sources: pricing policy decision · February monthly meeting

Availability, permissions, and retention policies vary by deployment. You also choose what the bot can read and retain.

Auto Research

Add a note to Inbox. Get the relevant context.

Add a note or task to Inbox, and Kroma Key gathers related materials and context within the scope you set, then organizes them in the ontology. You don’t have to repeat the same search every time.

01

Add it to Inbox

Capture a note or task as it comes to you.

02

Research begins

Kroma Key gathers related material and context within the scope you set.

03

It joins the knowledge map

The results are linked in the ontology so you can find them later.

Inbox
  • Starting an online store
  • Notes from a tax-advisor call
  • Initial marketing ideas
  • Competitor research
Auto Research
Starting an online store

We gathered material related to this note within the scope you set.

Collected materials
  • Marketplace vs. storefront fee comparison
  • Business registration guide
  • Initial inventory and cash-flow tips
Added to the ontology
Example: materials gathered through Auto Research from an Inbox note.

You control what Kroma Key researches and how far it can look based on your deployment and permissions.

Why adopt it?

Give every new AI session your team’s context

Conversations end, but the reasons behind decisions remain in the ontology. Use the Ontology API to pass that context to AI tools such as Claude Code and Codex, so a new session can answer using your team’s terminology and decisions.

Without Kroma Key
  • Re-explain the background every time you start a new AI session.
  • The reasons behind past decisions disappear when the conversation ends.
  • Each person explains the context differently, so AI answers vary.
With Kroma Key
  • Decisions and their rationale remain in the ontology.
  • Use the Ontology API to pass only the context a session needs.
  • AI answers from the same context, regardless of who starts the session.
01

Retain the context

Keep decisions, rationale, and terminology in the ontology.

02

Pass it through the API

Use the Ontology API to select and pass the context the AI session needs now.

03

Continue with shared context

A new session answers using your team’s terminology and decisions.

Use it with AI tools like theseClaude CodeCodexOther AI agents
New Codex session: "Why did we choose tiered pricing?"

When the Ontology API supplies the decision history, the AI can answer with evidence: "We moved from an across-the-board increase to tiered pricing to reduce churn among core customers."

bash · Start a new session with context from the Ontology API (example)
# 1) Download only the context you need from the ontology
curl -s "$ONTOLOGY_CONTEXT_URL" \
  -H "Authorization: Bearer $KROMA_KEY" > context.md

# 2) Start a new AI session with that context
"$AI_AGENT_CLI" --context-file context.md

# Actual endpoints and AI tool flags vary by deployment

Integration and security policies are configured for your deployment. You also choose the scope and permissions of the context you pass.

Can I trust it with our data?

Keep data and records under customer control

Review these controls before connecting decisions and documents. They matter most to security-sensitive organizations.

Keep data under customer control

Keep data on company servers with on-premises or hybrid deployment, or control individual access through a virtual organizational structure.

Maintain an audit trail

Record who accessed or changed information, when, and why.

Validate with a PoC first

Define the scope and security review criteria before starting. You do not have to connect everything at once.

Availability and security policies vary by deployment.

Who is it for?

The same model works for teams and individuals

For businesses

Connect team documents, decisions, meetings, and owners. Designed for organizations with frequent handoffs and audit requirements.

For individuals

Manage notes, decisions, and AI conversations in a personal knowledge map. It is cloud-based, with nothing to install.

For security-sensitive organizations

If data cannot leave the organization, keep it inside with on-premises deployment (installed on company servers) or a hybrid setup. Cloud is sufficient for many organizations, and on-premises is also supported.

Hardware options

When security requires it, design the hardware too

Not every customer needs on-premises deployment. For organizations where data location matters—such as finance, manufacturing, and R&D—Kroma Key can design storage, local AI, and backup policies together.
