Agents need a Brain.
Memory isn't enough.

Where everything a team and its agents learn lives.

People and agents write to one governed record. When a belief's grounds move, it reopens and everyone who relied on it is told. It installs like memory: correct one agent once, and every agent follows the rule. Connect the agent you already use, or start from the documents your team relies on.

Build, review, and use knowledge together.

Desktop agents

Connect Claude Code, Codex, Grok Bot, or any MCP client.

Embedded products

Connect through API or MCP without creating another silo.

Two ways in. One Brain.

Developers connect an agent or build Nicia into a product. Teams start from the documents they already rely on. Both write to the same governed record.

For developers

Connect your agent

Connect first. Your Brain is created when you connect, and every agent you add reads and updates the same one.

  1. Step 1Add your Brain to your agent

    Pick Claude Code, Codex, Grok Bot, or another MCP client, paste the one command Nicia shows you, and sign in when your agent asks.

  2. Step 2Paste the setup prompt

    Your agent saves what it reads as records, then updates those records when a second source says something new. Each change shows up before and after.

  3. Step 3Bring in another agent

    A new session, a teammate's agent or a different tool asks the same Brain and gets the current answer. You see exactly what it was served.

Connect your agent

Building it into a product? Copy the build prompt and paste it into Claude Code, Codex, OpenCode, or any coding agent. It provisions a Brain per customer over the HTTP API.

For teams

Start from your documents

Bring the few documents your team already relies on, not everything. Then have your agent record the rules and decisions they state, each citing the passage it came from.

Copy the import prompt and paste it into Claude Code, Codex, OpenCode, or any coding agent. The prompt is the whole procedure, so there is nothing to install first. Import is a copy, so your existing tools keep working exactly as they do today.

Step by step for each one Prefer to upload files in a browser?

Two agents and four tools is fine. Then it isn't.

Notion, Docs, Drive and Confluence are editing surfaces built for people, and they are good at that. Their unit is a page, their API is designed around a person clicking, and nothing in them carries a typed field, a review step, or a record of why something changed. An agent pointed at them is reading a layout to guess at facts.

They never held the truth. They held documents about it, and a person did the reconciling. Hand that job to agents and the reconciling does not disappear, it just happens faster, in more places, with nobody watching. A document is a fine rendering and a bad database.

Wiring N agents to M tools is N × M links to build, authorise and keep correct. Routing them through one Brain is N + M.

Week 1One person wires up one agent

Three tools, three integrations, and it works. This is the demo everyone gives.

31 × 3 connections
Agents on the left, tools on the right. Every line is something a person has to build, give a credential to, and keep correct.
  • Read from anywhere. Accept in one place.Knowledge is still born in Slack, email and meetings, and your agents can bring all of it in. Capture is many to one. Authority is one place. That is the part a mesh cannot do, because a mesh has no center.
  • Trying costs you nothing.An import reads; it never writes back. No OAuth scopes into your systems, no live coupling, nothing to unwind. Run both for a couple of weeks and compare the answers.
  • Then cut over, on purpose.A copy drifts the moment people keep authoring somewhere else, so this is a trial with a shelf life, not a resting state. When the Brain is the better answer, make it the place you write.

Agents that change things, not just answer questions.

Ask in plain language. The agent resolves it against the Brain's records and stages the whole batch as one change. Approve it once, and the moment it lands every surface that reads this Brain is current.

What you own is what you've learned.

Companies are handing work to agents and swapping models every few months, and nothing records what they've learned. Databases store rows, documents and agent memory store loose text, and agents built on them end up confidently out of date. A Brain is one governed record your people and agents build together. Change it once and everything that reads it is current.

One change. Every agent current the same minute.

Try it on a branch. Keep what works.

Open a branch and let agents rework the knowledge in parallel: a new pitch, a different pricing structure, a rewritten escalation policy. The version everyone else reads does not move. Propose the changes that earned it back to the main Brain and leave the rest on the branch.

Code got fast when changing it stopped being risky. Knowledge gets the same loop.

One Brain. Every way your organization works.

The same Brain your team edits in a browser is the one your desktop agents connect to and the one your product provisions per tenant. Nobody has to choose between a polished product and an extensible platform, and nothing has to be migrated when you move between them.

When the grounds move, it reopens.

Every rule and decision says what it rests on: another decision, an assumption, a passage in a document. When that changes, the record reopens and reads as needing review until a person revises it or says it still holds. Every answer carries citations and a receipt for exactly what was served, so the receipts name every agent that relied on the old version.

See exactly what each agent was served.

Every answer an agent reads through a Connection is recorded with the exact sources behind it, pinned to the versions the reader saw. That is how a reopened belief finds the agents that relied on it. Open any one of them and run a context check: it reports where the sources contradict each other, where the same passage was sent twice, and where you paid for words that carried nothing.

Point one agent at a few documents and you can check the first answer it gets.

For the people shipping the AI product

You already built a worse version of this.

Every team that gives its customers their own context ends up writing the same four things badly. We know because they keep describing them to us in the same words.

“Our RAG returns chunks, not answers.”
Ask what the current ICP is and a vector store hands back five passages from three different quarters, all of which retrieve equally well. Nothing in it knows that March was superseded in August. A Brain keeps typed records with corrections, so current is a property of the data instead of a prompt-engineering problem.
“Onboarding ingest is our worst code.”
Customers upload their materials at signup and you pull out a company description, an ICP, a product list. You wrote that once, you hand-tune it constantly, and it surprises you on every new customer. Declare the kinds you want, send the documents to a Brain, and get back records in those kinds, each traced to the passage it came from, ready to show the customer for confirmation.
“We are scared to change the schema.”
You did not plan for the model to evolve, so every new field is a migration and a backfill and a bad afternoon. Declaring a field in a Brain is retroactive: nothing you ever sent was dropped, so promoting a key makes values you already stored declared, returned, and filterable without touching a record.
“Every customer needs their own.”
A git repo cloned per customer, or a tenant column and some hope. Provision a Brain per tenant addressed by your id, with its own keys, its own review queue and its own export. No Nicia ids to store and nothing to reconcile.

The product your team uses. The platform you build on.

Start in Nicia, connect the desktop agents your team already uses, or provision one Brain per tenant from your backend. All three paths meet at the same review, policy, and provenance boundary.

Leaving is a feature

You arrived with a folder. You leave with a model.

Export any Brain and you get plain markdown with your frontmatter intact, a catalog, a greppable activity log, revision history, and an AGENTS.md that teaches any agent how to read the whole thing. No proprietary envelope, on every tier including the free one.

Talk to us

See it against your own knowledge.

Bring a folder, a wiki export, or just a description of what your agents keep getting wrong. We build the Brain on the call, point an agent at it, and you watch it answer from your own material. Thirty minutes, no deck.

You keep the export either way, whether or not you buy anything.

Your agents are ready for real work. Give them somewhere to do it.

Start with your agent, your documents, or your product. Every path builds the same thing: one governed Brain that your agents improve and your people steer.
