Build

Refine — macOS app, open sourceMIT License

A native macOS tool that rewrites text where you're already typing.

A global shortcut opens a native panel over any app. Select text, apply a transform — proofreading, rewriting, translation, or your own chained flows — and it's rewritten in place. A persistent clipboard keeps history locally.

Local-first by design: on-device inference through llama.cpp with Metal acceleration, with OpenAI, Anthropic, and Ollama available as optional streaming cloud providers. API keys live in the macOS Keychain, never in a config file.

Native integration goes deep — NSPanel, Cocoa, Core Graphics, simulated keyboard events for text injection — packaged, signed, and notarized, with an auto-updater built in.
