## What it is
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
