Remember, at platform scale
The second brain your agents actually use.
Brain2 turns everything your team and your agents produce into one governed knowledge graph. Not a chat log. A living memory the whole platform can reason from.
It grows on its own

In plain words
What it is, where it lives, when to reach for it
- What is it
- A knowledge base for your team and agents: markdown notes indexed into one searchable graph.
- Where do I use it
- In the dashboard's Brain view, and from your terminal through the quox CLI.
- When would I use it
- When an agent or teammate asks something your notes already answer, or a decision needs its history.
- How do I use it
- Run
quox brain search "<query>"in your terminal, or open the Brain view and search there.
Not a mock-up
This is what it actually looks like.
The living vessel above is the real shape of it, rendered live. Here is the same graph inside the dashboard's Brain view: every node an igniting neuron, every thread a connection between what you know.
Sources you connect are indexed on their own, every agent can search and cite it, and every note is scoped, provenanced and tamper-evident.
Not a database, a memory
Not a chat log. A living knowledge graph.
Most memory bolted onto AI is a chat log or a vector dump. Brain2 is different. It ingests everything worth keeping, consolidates it into weighted beliefs, and lets any agent retrieve and cite it, with the provenance attached.
Forget
A transcript is a record of what was said, not what is known. Nothing is consolidated, so nothing is easy to find again.
Sprawl
Everything gets embedded and nothing gets weighed. Retrieval returns whatever is nearby, not what is actually true.
Consolidates and cites
Raw material is distilled into beliefs with a confidence and a source. Every answer an agent gives can point back to where it came from.
One memory, three organs, one loop
Three organs, one memory, every agent.
Brain2 is three parts that feed each other, then hand off to whichever agent asks.
Brain
Grabs everything and makes it searchable, chunk by chunk.
QuoxDream
Consolidates the raw material into weighted beliefs while the tab is closed.
QuoxMemory
Holds the distilled version your agents read first.
Agent
Searches and cites it in the same turn, grounded and scoped.
The loop feeds itself, so the memory gets sharper over time, not noisier.
Server-side, on a schedule
It feeds itself.
Connect a source once and Brain2 keeps up with it on its own, server-side, on a schedule. Not a browser timer that only runs when a tab is open.
Sources are grouped by what they give your agents, and you turn on only the ones you want.
Explore your brain
See the shape of what it knows.
This is demonstration data, not a live account, but the shape is the same one you would see for real: notes gathering into vaults, hubs standing out as the ones agents cite most, and links forming between what actually relates.
Search plus context, every turn
Every agent can search it. Answers cite what you actually know.
Agents reach Brain2 two ways: a search tool they can call, and a knowledge context injected into every turn. Answers come back grounded in what you actually know, with citations, and scoped to the org and user asking.
One shared tool, every agent, no copy and paste into prompts.

The real interface
The Brain2 cockpit.
Not a mockup. A growth ring of the notes it holds, plus the full page with a note open, below.
- 1Facet by scopeOrg and You read as clickable counts, 1,551 and 331, so organisation-wide knowledge splits from your own notes before you open the graph.
- 2Facet by sourceAgent Memory, Dev Sessions, Git History and Quox Docs each carry a live count, narrowing the 1,882 notes down to one ingestion channel.
- 3Switch the graph modeBrain, 2D and 3D sit in one toggle, so the same notes render as the point-cloud vessel or a flatter layout.
- 4Watch the count take shapeFirst sparks reads 1,882 notes with 118 more taking shape, the same growth figures the ladder further down this page uses.
- 5Open a note's full detailSelecting a node opens its full record beside the graph, here a governed finding on HITL routing tool names with its origin session ID intact.
- 6Register a source or reindexTwo header actions let you add a new source or force a reindex without leaving the page.

The difference that matters
Scoped, provenanced, tamper-evident.
No standalone second brain can ingest a whole governed platform, its distilled knowledge, its audit trail, and your connected world, all scoped and provenanced. That is the difference. Brain2 knows where every note came from, who is allowed to read it, and can prove the evidence-grade records were not changed after the fact.
Scoped
Every note carries an org and a user boundary. Nobody reads across a scope they are not in.
Provenanced
Every note knows the source it came from and when it arrived.
Tamper-evident
Governed evidence ingested into Brain2 ties back to WARD, so the underlying record cannot be altered without it showing.
The write side
Does AI agent memory need governance?
Every memory article about AI agents treats memory as a read problem: retrieval, RAG accuracy, hallucination reduction. It is also a write problem, and that half gets skipped. Memory is accumulated state. Every note Brain2 stores changes what an agent believes going forward, and what an agent believes changes what it does next.
A write to memory is a decision with delayed effect: an agent that memorises a wrong fact today can act on it in a completely different context weeks later, with no action-level review to catch it, because the change happened at write time, not at the moment of the consequential action.
If actions get policy gates and an evidence trail, writes that shape future actions deserve the same treatment: who wrote it, what scope it is readable in, and a provenanced, tamper-evident record of the change.
Watch it fill in
It grows, and you can see it.
A live graph you can explore node by node, and a growth ladder from a handful of notes to a dense, connected mind. Your agents get sharper as it does.
Forming
A handful of notes, not yet connected.
Growing
Clusters appear as related notes link up.
Alive
Agents are citing it in everyday answers.
Dense
A connected mind, consolidated and current.
Explore the graph node by node in the cockpit, or watch the ladder move as new sources are connected.

The three parts
Brain2, Memory and Mind: how they fit together.
Three separate products that read from the same governed platform. Here is what each one actually does, and where the lines are.
The self-feeding graph
Connects to your sources once, then keeps indexing and consolidating them on its own into a governed, cited knowledge graph.
The memory layer
Persistent, tiered storage for what an agent has learned: episodic, semantic and entity memory that survives a restart or a cleared browser.
The reasoning layer
Twelve named cognitive implants that perceive, recall, reason and act, with every decision logged as evidence you can replay.
How they fit: Brain2 finds new sources and consolidates them into a governed graph, QuoxMemory holds the distilled result agents read first, and QuoxMind reasons over both to decide what to do next.
Second brain, answered
What a second brain is, and what makes this one different.
What is a second brain?
A second brain is an external, searchable store of what you know, so you can find and reuse it later instead of holding it all in your head. The idea started as a personal knowledge habit. Brain2 applies it to a whole platform: a shared second brain your AI agents read from and cite, not just one you read yourself.
What is Brain2?
Brain2 is Quox’s second brain for AI agents: a self-feeding, governed knowledge graph you self-host. It ingests the sources you connect, consolidates them into weighted, cited beliefs, and serves them back to every agent scoped and provenanced, with governed evidence tamper-evident back to WARD.
How is Brain2 different from a personal second brain like Notion or Obsidian?
Those are second brains a person reads and edits by hand. Brain2 is a second brain your agents read and cite, and it fills itself in on a schedule rather than waiting for you to file a note. It runs on your own QuoxCORE instance, so the knowledge stays yours.
Is my second brain private and self-hosted?
Yes. Brain2 runs on your own QuoxCORE instance, source credentials are encrypted with per-organisation keys, and every note is org-scoped so one team cannot read another’s. Nothing is sent to a third-party memory service; the one outbound call is to the embedding provider you configure (OpenAI or Gemini) to power semantic search.
Can a whole team share one second brain?
Yes. Brain2 is org-scoped, so a team shares one governed second brain: every agent and every person on the instance reasons from the same cited memory, with provenance on every belief.
For the longer argument on why a persistent second brain changes how agents work, read why second brains are useful.
Give your agents a memory worth citing.
Connect a source, let it index, and watch the graph grow. Every agent on the platform reads from the same governed memory.
How you get it
In the store today, a brain that feeds itself
One licence, installed on your own QuoxCORE instance.
On its own
A second brain that keeps itself current: it reads what you feed it, links what it already knows, and surfaces the connection when it matters rather than when you remember to search.
On top of QuoxMemory
Brain2 builds on QuoxMemory, the durable memory layer every Quox install already ships with. You are adding a way of thinking about the store, not a second store.
