# The company context engine
Every AI tool in your company starts from zero and keeps its own memory. Nerra builds one living context layer from the tools you already use and serves it to Claude, ChatGPT, Cursor and your own agents over MCP.

How Nerra works: your tools feed one company context layer, and every AI agent reads it over MCP
WHAT IT IS
## One shared memory of your company, for people and every agent
Auto-built from your real data, not from documents people forget to update.
### Builds itself from your real data
Decisions, policies, owners, customers: the context that normally lives in Slack threads and people's heads. Nerra reads your tools and keeps the layer current on its own. No wiki to fill in.
### One context for every agent
Claude, ChatGPT, Cursor and your internal agents all read the same thing over MCP. Connect once instead of wiring context into each tool separately.
### Answers you can check, memory that grows
Every fact carries its source and its status: confirmed decision, inferred pattern, or superseded, and by what. Agents write back what they learn, with permissions and human approval.
- Provenance
- State over time
- Conflicts surfaced
- Governed write-back
- Vendor-neutral
HOW IT WORKS
## Whether your workflows are simple or highly complex, Nerra configures itself around your organization's real structure, data, and teams.
01
### Connect your tools
CRM, Slack, Jira, support, email. Nerra reads data across your stack. No migration, no setup overhead. Your team keeps working as usual.
02
### Nerra builds your company context
Nerra maps the decisions, policies, people and customers your company works from. It learns how things actually are, not how a document from last quarter says they should be. The result is a living layer that stays current on its own.
03
### Every agent works from it
Your agents read the layer over MCP and answer from what's true now, with a link to where it came from. When an agent learns something new, it can write it back: a human approves it, and the next agent already knows it.
Nerra is not a wiki, not another chat app, not a per-tool connector. Call it a company brain if you like. What it actually is, is one shared company memory sitting between your data and every agent you run.
## “Why not just connect ChatGPT or Claude to our tools?”
Direct connectors search. They return the document that matches best, and they have no idea whether it still holds.
Thursday: your team changes the refund policy in a call.
Monday: someone asks an agent about refunds.
A connector returns the Notion page, confidently. Nerra answers with the new policy, cites the decision that changed it, and marks the old page as superseded.
Monday: Claude saves it
A decision saved in Claude on Monday is the answer another agent gives on Tuesday, with the source attached
Tuesday: Grok Bot uses it
INSIDE NERRA
## See the product
Three core views. One source of truth about how your company operates.
Nerra Knowledge Library: the company brain, with provenance, inbox of changes and known gaps
### A memory that knows what's true now
Your company's rules, decisions, people and context, built from real data. Inbox holds what changed and needs a decision. Gaps shows what Nerra still doesn't know, in plain view.
Nerra agent access control: scoped read and save rights per AI agent
### Governed access, not a free-for-all
Scoped read and save rights per agent. An agent never sees more than the person who connected it.

### Agents write back what they learn
Save something once in Claude. Every other agent knows it next time, with the source attached.
