Typeahead

Typeahead is a system-wide AI autocomplete app for macOS that finishes text in any app locally on your Mac, with no cloud service.

Typeahead

What is Typeahead?

Typeahead is a system-wide AI autocomplete app for macOS. It finishes text as you type across apps on your Mac, not just in one browser or editor, and it is designed to run locally so your writing stays on your computer.

The product is positioned as a Mac-native utility for people who do a lot of repetitive writing. It uses local AI models to suggest completions inline, letting users accept a suggestion with the Tab key. The app is sold as a one-time purchase rather than a subscription.

Key Features

  • Works across the Mac system: Typeahead can be used in any app where you can type, including email, Slack, documents, and editors, so it is not limited to one workspace.
  • Inline autocomplete with Tab acceptance: Suggestions appear as you type, and you press Tab to accept a completion, keeping the workflow fast and keyboard-driven.
  • Runs locally on your Mac: The app processes text on-device with local AI models, which means your writing is not sent to a cloud service.
  • Offline operation: Because processing happens on the Mac, the app can work without an internet connection after setup and license verification.
  • Adapts to your writing style: The app is designed to learn your voice over time so its suggestions can better match the way you write.
  • One-time purchase model: Typeahead is offered as a single payment product with no subscription or recurring fee.

How to Use Typeahead

Buy and download the app, then install it on a Mac running the required version of macOS. After opening Typeahead, start typing in any supported app and watch for inline completions.

When a suggestion matches what you want to say, press Tab to accept it. Over time, the app is intended to adapt to your writing patterns, so the suggestions should become more aligned with your usual phrasing.

Use Cases

  • Email drafting: Useful for people who send many routine emails and want help finishing repeated openings, closings, and follow-up language.
  • Slack and team messaging: Helps speed up short responses and recurring workplace phrases without switching to a separate writing tool.
  • Document and note writing: Works in apps like Notion or other Mac text fields where users draft longer notes, summaries, or outlines.
  • Developer-adjacent writing: Helpful for tasks outside code completion, such as issue descriptions, pull request summaries, and internal questions.
  • Non-native writing support: Can assist users who know what they want to say but want help completing sentences more fluently.

FAQ

Does Typeahead work offline? Yes. The source says all AI processing happens on your Mac, and the app works offline. License verification may happen at startup, and optional update checks may use the network.

Does Typeahead send my writing to the cloud? No. The product page says your writing stays on your Mac and that there is no cloud processing or telemetry.

What Mac does it require? The page says macOS 14 or later, with Apple Silicon or Intel support, 8 GB of RAM minimum, and about 3 GB of free disk space for the AI model.

Is it a subscription? No. Typeahead is sold as a one-time purchase.

Alternatives

  • Grammarly: A writing assistant focused on grammar and editing, especially in browser-based workflows, rather than system-wide autocomplete.
  • GitHub Copilot: An AI assistant for coding inside supported editors, aimed at code completion rather than general text across Mac apps.
  • Notion AI: A writing assistant inside Notion, useful if you mainly work in that app instead of needing autocomplete everywhere.
  • Built-in app autocomplete: Some apps offer their own predictive text or completion features, but those are usually limited to one app rather than working system-wide.
