About Grambo
Problem Fixing grammar often breaks writing flow. Most tools either interrupt while you type with constant underlines and suggestions, or require switching context completely. Tools like Grammarly can be distracting, while using ChatGPT or similar tools involves multiple steps like copying text, pasting it into another app, prompting, and then copying it back. These interruptions add friction and reduce productivity, especially for people who write frequently throughout the day. How Grambo solves this Grambo is designed to remove that friction and keep you in your writing flow. Instead of interrupting you while you type, Grambo works on demand. You simply select the text you want to fix, press a keyboard shortcut, and the corrected version replaces it instantly, right where you are. No popups, no switching apps, no extra steps. How it works Works across all apps on macOS where text selection is supported Uses a shortcut-based workflow: select β trigger β replace Supports multiple modes depending on user preference: Local AI for fully offline usage and privacy BYOK (Bring Your Own Key) to use your own OpenAI, Gemini, or Anthropic models Cloud mode for users who prefer a simple, no-setup experience What makes it different Grambo focuses on improving your workflow rather than adding more features. The goal is not to constantly guide or interrupt your writing, but to let you write freely and fix things only when you choose to. By reducing context switching and unnecessary steps, Grambo helps you stay focused and get more done without compromising on writing quality.
