macOS AI writing assistant that works inside any app
RewriteBar captures the selected text system-wide and pastes the improved version back, so it functions in Chrome, Google Docs, Word, Slack, Notion, VS Code, email clients and more.
Use built-in commands such as fix grammar, simplify, humanize, summarise, title case, fix JSON, create ASCII art or translate, or author your own commands with variables and prompt libraries.
Combine several actions to transform text step by step — for example expand, add emojis, translate and rewrite a title in one flow.
Bring your own API key from major providers, use the RewriteBar Gateway, or keep everything on-device with Ollama, LM Studio, oMLX or Apple Intelligence.

Your AI writing assistant, inside every app on Mac and iPhone
Select text anywhere on Mac or iPhone, run an action, and the improved result is inserted in place — no copy-pasting between tools.
Bring your own prompts, choose your preferred models (OpenAI, Anthropic, Google on Pro) and build repeatable workflows that sound like you.
Turn speech into clean, formatted text with Voice Mode and AI Dictation without leaving the app you are working in.
See every AI change and revert individual edits while keeping the rest, so you keep full control of the output.
