Brand

Canonical name

The product is always Rook Signal. Never Rook, Signal, Rook AI, or Rook Signals. The space between Rook and Signal is meaningful. It separates the company from the product.

What Rook Signal is

A quiet workspace for LinkedIn presence. You pick twenty accounts. Rook Signal watches them nightly and drafts replies in your voice. You clear the queue in ten minutes and close the tab.

What Rook Signal is not

• Not a scheduler. There is no posting queue and no send time.
• Not an automation tool. Every comment goes out when you press Post.
• Not a feed assistant. Rook Signal lives outside LinkedIn.
• Not a general content generator. The surface is replies, nothing else.
• Not a shared model. Your samples are private to your workspace.

Who built it

Rook Signal is built by Rook, the team behind Rook Links, Paym.me, Rook Dots, and Rook Recruit. Rook ID is the shared authentication layer across every Rook product.

The writing layer

Rook Intelligence is the writing layer inside Rook Signal. It is the persona, rule, and prompt shape that sits above your chosen provider. The layer is ours. The model is yours.

Voice and tone

We do not call ourselves an AI tool. The writing layer is Rook Intelligence. Marketing copy avoids hyphens, em dashes, and tech first phrasing. We say what the product does, not what it runs on.
