MacWriteBuddy fixes spelling, grammar, and punctuation in any Mac app. Select text, press ⌃⌥G, and the clean version replaces it in place (⌘Z undoes it). Run a model offline on your Mac (llama.cpp or Apple Intelligence) or bring your own OpenAI, Anthropic, Gemini, OpenRouter, or Ollama key. No login, and your writing never touches our servers. Fixing is free; Pro ($39 once) adds rewrite, translate, summarize, prompt improver, custom actions, and memory.
MacWriteBuddy is for anyone tired of copying text into an AI chat just to fix a typo, then pasting it back.
How it works:
Select text in any app (Mail, Slack, Notes, a browser tab, your code editor) and press ⌃⌥G
Check the word-level diff, press Return, and the fixed text lands right where it was. ⌘Z undoes it
Pick the brain: a small model running offline on your Mac (Qwen3, Llama, Gemma, Phi, Mistral, or Apple Intelligence), or your own key for OpenAI, Anthropic, Gemini, OpenRouter, Ollama, and 13 more
No login, no account. Your writing never goes through our servers, and password fields are always skipped
Fixing spelling and grammar is free forever. Pro is a one-time $39 (launch price, regularly $79) and adds clearer, shorter, friendlier, and formal rewrites, Translate, Summarize, Improve prompt for AI chats, your own actions, and on-device memory for names and style.
I'd love to hear which shortcut you'd want next, and which model works best for you 🙏
