# instibrain

> One curated brain your team owns, that every AI you hire can read. Plain markdown files on your devices, an MCP endpoint for any agent, and a server that stores the secure area as ciphertext it cannot open.

instibrain is made by WebWork AI, Inc. A brain is divided into an open area the server can read and a secure area it cannot; you choose, page by page, which one a page is in. The wire contract, the security model with its limits stated, and the sync client's commands are published in full on the pages below.

## Start here

- [Home](https://instibrain.ai/): One brain your company owns and keeps feeding, read by every AI you hire — today's and the ones that do not exist yet. What you mark secure, we cannot read.

## Product

- [The brain](https://instibrain.ai/brain): What a brain holds, the three ideas it is built from, the MCP tools an agent uses to read it, and the cockpit you see it in. Nodes, scopes, the two areas.
- [Sync client](https://instibrain.ai/device): The sync client owns the files, the keys and the sync mechanics on your machine, and it stops rather than overwrite when two devices disagree about a node.
- [Agent](https://instibrain.ai/agent): Your brain is an MCP server. What the AI you already pay for does once connected: read context first, merge what a 409 leaves behind, write back what it learns.
- [How it works](https://instibrain.ai/how-it-works): The full mechanism: the ten-field node, the dominance rule the server enforces, the 409 merge path, and the two transports that carry both areas.
- [Security](https://instibrain.ai/security): The encryption behind the secure area: primitives, the key hierarchy, what a compromised host gets, the reader-substitution attack, and limits stated plainly.
- [Tour](https://instibrain.ai/tour): The whole product on one page: three parts and one rule, then five steps from a file on your laptop to your AI reading it, and who else can read it.

## Resources

- [Use cases](https://instibrain.ai/use-cases): How a company uses one brain: sales, support, engineering, operations, legal, new hires, and the systems your AI runs. What each writes down, and who reads it.
- [FAQ](https://instibrain.ai/faq): What a company asks before it trusts a brain with its memory: what we can read, where keys live, what happens if we shut down, teams, and agents.
- [Glossary](https://instibrain.ai/glossary): Every word the instibrain site and protocol use, defined once and grouped five ways: the store, the two areas and their keys, sync, the one rule, and agents.

## Company

- [Why instibrain](https://instibrain.ai/why): The bet behind instibrain: the model changes every few months, the context compounds for years, and a company feeds a brain only if the host cannot read it.
- [Getting access](https://instibrain.ai/signup): instibrain opens company by company. What an account is, what comes with it — one brain, the sync client, an MCP endpoint any AI reads — and where to sign in.
- [Contact](https://instibrain.ai/contact): How to reach the team behind instibrain: general enquiries, security reports, privacy requests, and legal matters, with the addresses for each.

## Legal

- [Privacy](https://instibrain.ai/privacy): What this site and the account plane collect: no cookies here, no trackers, one session cookie for an account, and two areas with different readability.
