About CapyBro

CapyBro refines, rewrites, and translates your text directly inside any Windows application. By running in the background, it allows you to instantly polish emails, modify writing tones, and correct grammatical errors without switching windows or copying and pasting back and forth. It processes text using either cloud-based language models or fully private local AI engines, ensuring your writing is clear and accurate across all of your active software.

Who is CapyBro for?

Writers, developers, and students who frequently compose text in different applications and previously spent their days manually copying drafts into web-based AI tools to fix grammar, translate, or adjust tones. It is built for those who require seamless editing directly inside code editors, word processors, browsers, or email clients, particularly users needing strict local privacy for sensitive data.

How does CapyBro work?

First, select any text inside any Windows program and press your custom hotkey combination. Next, choose a pre-configured command like formal rewriting, grammar correction, or translation. Finally, review the diff preview side-by-side to compare the original draft with the AI generation, then instantly replace the text in-place or make manual edits before applying.
