What is Rook?

Smart enough to strategize.
Private enough to trust.

You want the power of a large language model without surrendering your data to the cloud, but the options are limited or expensive. Rook delivers private, secure LLM-powered knowledge management for organizations and small businesses.

Give Rook access to only the files or data you want to search, and you're set.

Named for the chess piece that moves with precision and the corvid famous for its uncanny intelligence, Rook is built to think ahead, act decisively, and stay on your side of the board.

Use Cases
01
private access private data

Rook Sovereign

For Your Private Data

Most organizations are sitting on years of unorganized institutional wisdom: meeting notes, decisions, and documents, scattered across drives and inboxes. Rook Sovereign connects to your private data sources and makes them searchable. Ask a question in plain language, get a synthesized answer with sources you can trace back.

Works well for:

  • Teams with years of accumulated knowledge scattered across their digital infrastructure
  • Organizations that handle sensitive data and can't risk third party processing
  • Co-ops, nonprofits and mission-driven organizations who need enterprise-grade knowledge tools without the surveillance factor
  • Any team that keeps asking the same questions because nobody can find where the answer lives

One thing to know: Sovereign runs on your infrastructure and your infrastructure only. Setup takes more than a single click, but that's the point.

Deploy on-premise, or in your private cloud.

02
public access public data

Rook Commons

For your Public Data

Your organization has spent years producing reports, research, policy papers and public resources. Commons puts a conversational interface on top of your public body of work so that anyone who visits your site can ask a question and get a real answer, with the source right there alongside it.

Works well for:

  • Think tanks and research organizations with large public archives that rarely get the readership they deserve
  • Advocacy and policy organizations whose published work needs to reach practitioners, journalists and decision-makers quickly
  • Academic institutions making their research accessible beyond specialist audiences
  • Nonprofits and foundations with Creative Commons-licensed materials they want people to actually use

One thing to know: Commons draws from the resources you give it, so the quality of the answers reflects the quality and breadth of your published work. Which for many organizations is exactly the point.

No authentication required.

private access public data

Rook Foyer

For Authenticated Access

Not everything needs to be locked down: Sometimes the knowledge is already in your public documentation, your published research, or your official records. Foyer makes it useful to the people who need it, without requiring them to know where to look or how to ask.

Works well for:

  • Onboarding tools that guide new hires or members through publicly available training and process docs
  • Press and media portals where journalists get accurate sourced answers from your public record
  • Academic or researcher access to your published work and public data
  • Cross-org collaboration where partners need your public knowledge but not your internal operations
  • Public consultation tools for governments and nonprofits drawing on official documents

One thing to know: Foyer is not a public website. It is a quality experience reserved for the people you have decided should have it.

Authentication layer required.

public access private data

Rook Ledge

For Selective Access

Sometimes the people who need your knowledge don't need to see all of it. Rook Ledge searches your internal knowledge base and opens a door that's exactly as wide as you want it. Think: a helpdesk that answers HR questions but never surfaces salary data, or a member portal that knows your bylaws but not your board deliberations.

Works well for:

  • Staff helpdesks that answer policy and process questions without a human in the loop
  • Member or resident portals for co-ops, unions, and nonprofits
  • Client-facing project knowledge without exposing your full internal docs
  • Compliance and governance queries scoped to what each role should see

One thing to know: What Rook surfaces is only as private as you configure it. Scoping and output filtering aren't optional extras here. They're the whole point.

Knowledge scoping and output filtering are essential.

Features

Document Search

Your team's knowledge is probably scattered throughout your shared digital workspace. Rook searches all of it at once and gives you a direct answer with the source attached, so you know exactly where it came from.

Works where you work

Some people work only in the browser, others prefer the Terminal, while some want a bot sitting in their chat. Rook works in all three without making you change how you work.

Grows with your team

Rook ships with a core set of tools and gets more capable as your needs change. Adding a new integration is as easy as adding a new tool to your trusted list.

Connects to what you already use

Rook talks to the services your team already depends on. Ask it to check a calendar, find a report, or add an issue to your team's project board. It handles the legwork so you can stay in the conversation.

Sovereign

Your data never leaves the board.

Most AI tools are cloud services in disguise, with your queries, documents, and team's data flowing through servers you don't control. Rook is different. We've designed Rook to run on your machine or your server. And our test demos run on our server in Toronto.
