Cotabby is an open-source macOS menu bar application that provides local, on-device AI autocomplete (ghost text) in nearly any text field across the system. It runs entirely on the Mac using Apple Intelligence or bundled open-source LLM engines (via llama.cpp), with an optional OpenAI-compatible server engine.

Use cases

• get AI autocomplete in any Mac text field
• accept inline word suggestions with Tab while typing
• run AI text suggestions fully offline and privately
• use local LLMs for writing assistance in Slack or iMessage
• avoid cloud AI services for text prediction
• add inline macros and autocorrect-style suggestions system-wide

When to choose

• you want on-device, privacy-preserving AI autocomplete across all macOS apps
• you prefer open-source tools with no accounts or telemetry
• you have a Mac (macOS 14+) capable of running local models

When to avoid

• you need AI autocomplete on Windows, Linux, or mobile
• your hardware cannot run local LLMs smoothly
• you want cloud-model quality and are fine sending keystrokes to a server
