Show HN: Chrome Extension to access the OpenAI API from any textbox

The "Barra AI" browser extension, available on GitHub, offers a simple AI browsing experience without subscriptions. Users can type `/ai` followed by a prompt in various input fields to receive AI-generated responses from the GPT model. Key features include no popups, client-side processing, and being free and open-source. Installation involves adding the Chrome extension from the Chrome Web Store and configuring the OpenAI API key. However, the extension does not function on sites using the Lexical editor framework. Developers can contribute by forking the repository and following the provided steps. More information can be found on the Barra AI GitHub repository.
