Cotypist

Cotypist is a macOS desktop AI autocomplete app for Apple Silicon users who want faster, more accurate writing across most apps without switching to a chatbot or editor.

Key capabilities include:

• System-wide inline suggestions that predict words and sentences as typing continues in virtually any application
• Flexible acceptance controls, including accepting suggestions word-by-word or all at once to keep the writer in control
• On-device processing (offline capable), keeping typed text on the Mac instead of sending it to the cloud
• Pro features such as custom instructions, training on personal writing style, and multi-device use (up to 3 devices)

Pricing: Freemium. Currently free during beta. A 30-day free trial unlocks full Pro features; after the trial, free usage is limited (50 completed words per day). Planned tiers include Casual (free), Plus (unlimited completions on 1 device), and Pro (unlimited completions on up to 3 devices); paid pricing is not listed.

What makes it notable: it runs entirely locally on Apple Silicon (macOS 14+), prioritizing privacy and low latency for real-time typing, and it integrates via macOS Accessibility APIs instead of requiring a proprietary writing interface.
