Versioned and auditable facts
Each fact keeps its history, owner, approver, and the date a version became true. Answers and changes can be traced back to their source.
NOAN
Freemium
NOAN is a fact layer and API for businesses that want websites, applications, and AI agents to use the same verified company information. It organizes approved, versioned business facts in a connected workspace accessible through REST and MCP.
What is NOAN?
NOAN is a business knowledge and infrastructure platform built around verified facts. A fact represents a company truth with a current value, an owner, approval information, version history, permissions, and links to related business data. Facts are organized into stacks and blocks and connected in a company graph, giving people, applications, websites, and agents a shared source of business information rather than relying on disconnected documents or copied prompts.
The platform exposes this fact base and its surrounding workspace through a REST API and MCP. Websites and agents can read facts as JSON, while applications and agents can also work with tasks, contacts, notes, assets, tags, and fact versions. Changes are recorded and versioned, and agents can propose new facts without adding them to the fact base until a person verifies them.
What can NOAN do?
Connected company graph
Facts connect to contacts, tasks, assets, and other facts, preserving context and exposing overlaps, dependencies, and gaps in documented business knowledge.
REST API access
A bearer key and standard HTTP requests provide programmable access to verified facts and workspace objects. Facts are returned as plain JSON and API keys inherit the permissions of their owner.
MCP support for assistants and agents
NOAN provides an MCP server and a setup wizard for connecting coding assistants such as Claude Code, Cursor, and Codex to the workspace.
Workspace operations
The API supports stacks and blocks, contacts and notes, tasks, assets, tags, and the identity associated with an API key. Tasks can be assigned, tagged, linked to contacts, and moved through statuses.
Human verification for agent updates
Agents can suggest facts, but a human must verify a proposed change before it becomes part of the fact base.
Use Cases
“Keeping websites current”
A website can read pricing and other company facts through the API. When a fact changes, the site can use the new version rather than relying on manually copied content.
“Grounding business agents”
Multiple agents can read the same current fact base at runtime, so their outputs use shared company information. Agent work is dispatched and tracked through the task manager.
“Building headless business applications”
Developers can use REST endpoints to create applications around contacts, notes, tasks, assets, and structured business knowledge without adopting a specific SDK or framework.
“Managing changing company knowledge”
Teams can review ownership, permissions, versions, and historical states to understand what the business knew at a particular time and who approved a change.
Frequently Asked Questions
What is NOAN?
NOAN is a fact layer for agentic business. It stores verified, versioned, permissioned company facts and serves them to people, apps, websites, and agents through one API and MCP connection.
How do agents stay grounded in current information?
Agents read facts at runtime before acting. They can propose new facts, but a human must verify those proposals before they enter the fact base. Agent tasks and notes are also recorded on the task board.
How can a developer connect to NOAN?
Create an API key under Settings, then use the bearer token with standard REST requests. A GET request can return verified facts as plain JSON. The site also provides a wizard that connects supported coding assistants to the NOAN MCP server.
Can NOAN manage more than facts?
Yes. Its API covers stacks and blocks, contacts, notes, tasks, assets, tags, and fact versions. Tasks can be assigned and linked to tags, contacts, and other workspace context.
Is there a free plan?
The pricing page lists a free plan for one person with one project, 40 facts, 150 contacts, and one API key. Paid plans add capabilities such as unlimited facts and contacts, team seats, higher limits, roles, shared workspace features, and priority support depending on the plan.
