Cotypist

What is Cotypist?

Cotypist is a native macOS writing assistant that adds inline autocomplete to the apps where you already type. It helps users draft emails, notes, documents, messages, and prompts more quickly by predicting words and phrases directly in text fields. The app is designed for people who write frequently on a Mac and want system-wide suggestions instead of working in a separate editor or web tool. Cotypist runs on Apple Silicon Macs and is built around on-device processing, so its predictions are generated locally on the Mac. It works across many common Mac apps and lets you accept suggestions as you write, making it useful for everyday communication, knowledge work, and prompt-heavy workflows.

• Lets you accept suggested text directly from the keyboard

Safety overview

Status: Mostly safe

Cotypist is a legitimate Mac writing tool. For its system-wide autocomplete features, it may need macOS accessibility or similar input-related permissions so it can read text context and show suggestions in other apps; that access is normal for this kind of software. Because it interacts with what you type, use it only if you are comfortable granting those permissions and avoid using predictive assistance where highly sensitive text must stay completely manual.

Recommendation: Keep Cotypist if you actively use inline writing suggestions across Mac apps. If you tried it and no longer want autocomplete in your typing workflow, removing it is reasonable and will simply stop its predictions and any app-specific setup you made.
