What does Beamcast do?

Beamcast is a browser extension that puts a powerful AI assistant right where you work. Instead of constantly switching tabs to a chatbot, you can select text on any webpage—be it an email draft, a code repository, or a news article—run an AI command from a menu, and see the results appear instantly. It’s designed to weave AI directly into your existing browsing workflow, making common tasks like rewriting, summarizing, or explaining information much faster.

What makes Beamcast stand out is its focus on commands and customization. It comes with a handy set of built-in commands for practical tasks, but you can also create and save your own custom prompts. These commands are securely synced via the cloud, so your personal AI toolkit is available on any browser where you install the extension. Under the hood, it leverages powerful models from OpenAI and Google Gemini, giving you flexibility in which AI does the work. The free tier is generous, allowing you to use your own API key or providing starter credits.

This tool is a perfect fit for anyone who finds themselves frequently asking an AI for help while working online. Writers can polish drafts in their CMS, developers can get explanations for unfamiliar code on GitHub, and students can quickly summarize complex articles. It cuts out the copy-paste shuffle, letting you apply AI intelligence directly to the text in front of you, which is a genuine boost for daily productivity.
