Beamcast

Beamcast is a browser extension that brings ChatGPT and Gemini directly into any webpage, letting users select text and run an AI command on it without switching tabs or copying content elsewhere. It ships with a built-in library of ready-made commands for tasks like rewriting text, answering questions, and summarizing content, and also lets users create and save their own custom prompts as reusable commands. Custom commands sync across devices through the extension's cloud storage, so a command created on one machine is available wherever the extension is installed. Beamcast supports multiple underlying AI models, including several GPT-3.5 and GPT-4 variants alongside Gemini, giving users some choice over which model handles a given request. The tool is aimed at people who use AI models frequently throughout their workday, such as writers, developers, and researchers, and want quick access to them from inside whatever site they're already working in rather than a separate chat window. Beamcast is distributed as a Chrome and Firefox browser extension. Pricing follows a freemium model: the free tier includes 50 credits, access to all supported models, and the ability to create up to 10 custom commands, with paid plans presumably unlocking higher usage limits, though specific paid pricing was not confirmed in the research gathered.
