Plainspeak

Plainspeak is a unique tool designed to refine how your digital assistants communicate, ensuring clarity and conciseness. Key features: • Enforces plain language and short sentences • Eliminates filler words and jargon • Bans em dashes for directness • Integrates seamlessly with existing agents This open-source solution provides a "voice layer" that applies a small, consistent set of writing rules to every response. It prevents digital agents from producing overly complex, robotic, or lengthy replies, making interactions more human-like and efficient. Users no longer have to contend with phrases like "certainly!" or excessive corporate buzzwords. It keeps the output simple, direct, and easy to understand, significantly improving the user experience. Plainspeak is ideal for developers and teams using code assistants, writing tools, and other interactive digital agents who want to enhance communication quality without constant manual oversight. It works with a range of popular platforms, including Claude Code, Codex, GitHub Copilot, OpenCode, Cursor, Windsurf, and Cline. Installation is straightforward, requiring no API key, and its MIT license makes it a flexible addition to any development environment. Just install it once, and your agent will maintain a clear, plain voice automatically.
