1. Install and open Summa
Download the app, drag it to Applications, and open it. Summa lives in your menu bar, not in a window. On first launch it asks for Screen Recording permission, that is how it reads the page you are on. Grant it and relaunch if prompted. Open Settings from the menu bar icon.
Option A: Enter a beta access code
The simplest path. In Settings → Premium AI Account, paste your code into the Beta access code field. That is it. Requests run through Summa's server, so nothing else to configure and no key to manage.

Option B: Bring your own Anthropic API key
Prefer to run it on your own account with no usage limit? In
Settings → Premium AI Account, expand
Advanced: direct API key and paste an Anthropic key
(it starts with sk-ant-). Summa then calls Anthropic
directly and you are billed by Anthropic for what you use.
You can create a key at console.anthropic.com under API Keys. A little usage goes a long way; reading a full chapter is typically a few cents.
That's it
