About NOAN

What Is NOAN

NOAN keeps the facts a company runs on in one place and serves them to agents over a single API. Each fact belongs to a block, and each block sits in a stack such as pricing, positioning, customers or policy. An agent asks for the block and gets the current version, along with who verified it and when.

The problem it targets is drift. A price lives in a system prompt, a sales deck and a help article, and two of those are usually stale. Retrieval and memory make it worse because they return whatever looks similar, not what is true today. NOAN holds one approved answer per block, so a change in one place reaches every agent and page that reads it.

The limits matter too. NOAN doesn't write copy or make decisions. It stores and serves facts, so the layer is only as good as the upkeep behind it. The free plan stops at 40 facts and 150 contacts, and paid plans start at $99 a month. Nothing becomes truth until a person approves it, which is the point of the product and also a step nobody can skip.

Getting Started

  1. Create a workspace at app.getnoan.com/join. The free plan asks for no card.
  2. Create a project, then a key for each agent, app or site. Scope each key to the stacks it should read.
  3. Connect over MCP at mcp.getnoan.com/mcp, or call the REST API at api.getnoan.com/v1 with a bearer token.
  4. Read the current fact for a block, for example GET /v1/facts?block_slug=pricing. The response carries the version, the verifier and the sources.
  5. Let agents post new versions. Turn on review for a key and their writes wait for a person before anything can read them.

Best for

The users, tasks, and scenarios where this tool fits best.

Users

  • Founders and operators running agents
  • Developers building agentic apps
  • RevOps and support leads

Tasks

  • Keeping pricing and packaging consistent
  • Giving agents customer and account context
  • Tracing a quoted number after the fact
  • Onboarding a new agent or tool

Scenarios

  • A sales agent drafts a renewal email and pulls the current Team plan price in one call, with the receipt to back it up.
  • A marketing site renders its pricing page from the company knowledge API, so the page and the sales deck never disagree.
  • An agency or partner reads shared facts by version, which keeps their copy in step with yours without a shared document.

Key features

Versioned facts, one current answer

NOAN organizes knowledge as a stack, then a block, then a fact. Each block holds one current fact, and every change creates a new version rather than overwriting the old one. An agent reading a block gets today's answer, and the older versions stay in the history.

One key over REST and MCP

The same API serves REST calls and remote MCP clients including Claude, ChatGPT, Cursor and Codex. Authentication is a bearer key, requests and responses are JSON, and the model behind your agent is a separate choice. Swap the model and the facts stay where they are.

Verification receipts and sources

Every approved fact records who verified it and when, and it can carry the URL and quote it came from. That turns a number into a claim with an owner. When a customer asks why an agent said $299, the receipt is one lookup away.

Scoped keys and review before publish

You create a key per agent, app or site and limit it to the stacks it needs. Keys can require review, which means an agent's write lands as a proposal and waits for a person before any reader sees it. Agents get their own identity, so the board and the audit trail show their work.

Time travel and visible gaps

You can ask what was true on a past date, which helps when a contract or a quote needs checking against the facts at the time. When a block has no fact, NOAN reports the gap instead of guessing. Missing information is treated as information.

The rest of the operating context

Facts sit beside people, notes, tasks and assets in the same workspace. A task board is shared by people and agents, and agents pick up work by tag. On Team and Enterprise, Verity answers in Slack from the same facts, so a question in a channel and a task on the board resolve to one truth.

Pros and cons

Pros

  • A change lands once and every surface that reads the fact picks it up, including agents, apps and public pages.
  • Each answer arrives with a version, a verifier and often a source, which makes audit questions answerable.
  • Review on write gives teams a way to let agents update facts without letting them publish unchecked.
  • REST plus MCP covers both code and chat clients, and keys can be scoped per agent or per site.
  • The free plan is a working workspace, not a demo, with one project, 40 facts and 150 contacts.

Cons

  • The product is only as useful as the facts you put in it, and an empty workspace returns nothing.
  • The free plan's 40 facts and single key run out fast once a few agents and stacks are live.
  • Paid plans have no trial, so testing beyond the free limits means committing to $99/mo or $299/mo.
  • It holds company facts rather than general knowledge, so it won't answer questions outside your own business.

Frequently asked questions

NOAN stores the facts a company wants its AI agents to repeat, such as prices, plans, policies and positioning, and serves them over one API. Teams use it so an agent quotes the current number instead of a version it found in an old document.
