Product Overview
What is Cotypist?
Cotypist is a macOS app that brings inline predictive autocomplete to every text field on your Mac β Mail, Slack, Notion, Obsidian, browsers, and more. Unlike chatbot-style writing tools, Cotypist never interrupts your flow: suggestions appear as you type, and a single Tab keystroke accepts the next word. All processing runs locally on Apple Silicon, so your text never leaves your device. The more you write, the more Cotypist adapts to your vocabulary and phrasing, keeping your voice intact while cutting your keystrokes roughly in half.
Key Features
System-Wide Inline Autocomplete
Suggestions appear directly inside any Mac text field β no switching apps, no prompting. Tab accepts the next word; keep typing to dismiss or redirect the suggestion in real time.
Fully On-Device Processing
Runs local language models (Gemma, Qwen) entirely on Apple Silicon. No cloud calls, no data logging, and full offline support β your words stay on your Mac.
Adaptive Personalization
Learns your vocabulary, names, and phrasing over time. Custom writing instructions and per-app settings let you tune tone and style for different contexts like email, Slack, or documentation.
Word-by-Word Acceptance
Press Tab once to accept just the next suggested word, then continue typing. Partial acceptance keeps your voice intact even when only part of a suggestion is useful.
Autocorrect and Typo Detection
Spots typos inline and offers the fix as a natural completion β no red squiggles or pop-ups. Available on Plus and Pro plans.
Flexible Plans with Free Tier
Free plan covers 100 completed words per day. Plus ($6/mo) offers unlimited completions on one Mac; Pro ($9/mo) adds the full model catalog, per-app instructions, clipboard awareness, and up to three Macs.
Use Cases
- Email and Messaging : Draft thoughtful replies faster in Apple Mail, Outlook, or Slack without switching to an external AI tool. Suggestions land inline and sound like you, not a chatbot.
- AI Prompt Writing : Speed up prompting inside ChatGPT, Claude, and coding agents. Cotypist helps you find the right words for your prompts without breaking your workflow.
- Documentation and Technical Writing : Repetitive phrasing in docs, READMEs, and support replies is where prediction accuracy is highest β cutting typing effort significantly on routine but important writing.
- Marketing and Content Creation : Cotypist picks up campaign voice as you write, reducing blank-cursor time and helping produce more drafts without outsourcing your tone to a generative model.
- Inclusive and Accessible Typing : Lowers the typing burden for non-native English speakers, dyslexic writers, and people with limited hand mobility β the same completions work across many languages.
