Inline autocomplete in Mac apps
Cotypist predicts your next words inline as you type, so suggestions appear in the app you are already using instead of a separate chatbot window.
Cotypist
Cotypist is a Mac autocomplete app that suggests words inline as you type in other apps. It runs on Apple Silicon Macs, works on-device, and is built to reduce typing without leaving your current workflow.
What Cotypist does
Cotypist is a smart autocomplete app for Mac that suggests the next words as you type in other apps. It is built to keep you in your current workflow: suggestions appear inline, you accept them with Tab, and the app learns from the words, names, and phrasing you use over time.
The product is designed to run on Apple Silicon Macs and process writing locally on the device rather than in the cloud. The site positions it as a way to reduce typing, avoid app switching, and help with everyday writing tasks such as email, chat, prompts, documentation, and social posts.
Core capabilities
Word-by-word acceptance
Press Tab to accept the next word or the whole line, or keep typing to ignore a suggestion and let Cotypist adapt to what you intended to write.
On-device processing and offline use
The app runs on your Mac rather than in the cloud, which the site says keeps your writing private and lets it work offline.
Context-aware suggestions
Cotypist checks the text field you are actively typing in and can optionally use surrounding screen context to make suggestions more relevant.
Typing assistance beyond completion
It can correct typos inline, offer emoji suggestions, and work across different languages and writing contexts.
Personalization and control
The pricing page describes customization options such as completion length, global writing instructions, per-app instructions on Pro, and model selection based on your Mac.
Common ways people use Cotypist
Daily email and chat replies
Draft replies faster in Mail, Slack, or support tools by accepting completed words as you type, instead of switching to another AI assistant or retyping the same phrases.
AI prompting without app switching
Use Cotypist while writing prompts for ChatGPT, Claude, or coding agents to reduce keystrokes and keep the prompt-building flow inside the same app.
Repeatable content drafting
Speed up repetitive writing in documentation, marketing copy, and social posts by letting the app learn recurring terms, names, and phrasing.
Inline typo correction
Catch and fix typos inline as you write, which is useful when you want a cleaner draft without dealing with separate pop-ups or later cleanup.
Accessible typing support
Support multilingual or physically challenging typing situations, including non-native English writing and one-handed use, by reducing the amount of manual typing required.

FAQ
How do I install and set up Cotypist?
Cotypist runs locally on Apple Silicon Macs. The onboarding flow shows a DMG install, moving the app to Applications, then opening it and following the setup instructions. Accessibility permission is required for autocomplete to work; Screen Recording is optional and can be skipped or revoked later.
Does Cotypist offer a free trial?
Yes. The pricing page says every new install starts with a 30-day Pro trial, with no credit card required. After the trial, accounts move to the Free tier automatically and settings remain intact.
What platforms does Cotypist support?
Cotypist is Mac-only today and runs entirely on Apple Silicon Macs. The site also says it works in every Mac app and most text fields, so it is not available for Windows or Linux at this time.
Can I use one subscription across multiple people?
Cotypist is designed for one person’s use. The Plus plan covers one Mac, and Pro covers up to three Macs on the same subscription, but the site says subscriptions are not shared between different people.
What permissions does Cotypist need?
Cotypist uses standard macOS permissions. Accessibility is required, while Screen Recording is optional and helps it understand surrounding context; passwords are automatically blocked by macOS unless a user explicitly reveals them in an app or website.
