Getting Started
Welcome to plenz. We run completely entirely in your browser environment, which means your prompt text never routes through a unified backend server and stays private by default. Let's get your workspace set up.
Install the Extension
First, download the plenz extension from the Chrome Web Store. Once installed, be sure to pin it to your browser toolbar for quick access. This allows you to easily hop into settings or toggle extension status.

Select your AI Provider
plenz works with the major AI language models. Since we use a "BYOK" (Bring Your Own Key) model, you only pay for your literal inference costs directly to the provider, with zero markup. Click on the plenz icon, open Settings, and select a provider from the dropdown.

Obtain Your API Keys
Retrieve a valid API key from your preferred provider to proceed. The keys are instantly stored in `chrome.storage.local` within your browser and never leave your environment. Expand the sections below to find exact instructions for the provider you just chose.
