Installation

Prerequisites

• An AI coding tool - Cursor, Claude Code, GitHub Copilot, or any AI you prefer

fai layers on top of your AI tool. It gives your AI memory that compounds.

Install

Pick your platform - Deno is installed for you automatically if needed:

Windows (PowerShell):

iwr -useb https://www.fathym.com/fai/install.ps1 | iex

macOS / Linux:

curl -fsSL https://www.fathym.com/fai/install.sh | sh

Already have Deno? Run directly:

deno run -A jsr:@fathym/fai/install

Run

fai

That's the whole setup. You're building.

What Just Happened?

In those 3 seconds:

• Your workbench was created
• Your context was initialized
• Your AI is connected and ready

You didn't configure anything. Your workbench set itself up based on your project. From here, everything you do compounds.

Time Promise

<3 seconds. From fai to building - with full context from your last session. Tomorrow, next week, next month - your AI remembers.
