Cotypist is a Mac app that provides smart, on-device autocomplete for all your writing, predicting your next words and phrases.

Cotypist is a Mac-only application designed to enhance typing speed and writing flow by predicting the next words and phrases in any Mac app. It runs entirely on Apple Silicon Macs, processing all data locally on the device to ensure user privacy and data security. The tool learns from the user's unique writing style, vocabulary, and phrasing, aiming to augment writing rather than replace it. The application integrates seamlessly across various Mac text fields, including email clients, messaging apps, browsers, and documentation tools. It offers features like word-by-word acceptance, emoji suggestions, typo correction, and support for multiple languages. Cotypist is particularly beneficial for non-native English writers, dyslexic typists, and individuals with physical typing challenges, helping them maintain a consistent writing pace and reduce typing effort. Cotypist aims to eliminate the need for users to switch to external AI chatbots for assistance, providing inline suggestions that feel like an extension of the user's own thoughts. It offers a free tier with daily word limits and paid plans for unlimited usage and advanced features, including deeper personalization and multi-Mac support.
