Typeahead

Typeahead

Typeahead is a macOS app that adds AI autocomplete to every text field across every application, accepted with the Tab key. As you type in email, Slack, Notion, Google Docs, or a code editor, Typeahead suggests inline completions the way an editor suggests code. It runs a local model entirely on-device, GPU-accelerated, so Typeahead works offline with no servers, no account, and no telemetry — nothing leaves your Mac — and it learns your writing voice over a few days of use. It supports more than thirty apps and requires macOS 14 or later. Where cloud writing tools send text off-device, Typeahead keeps everything local by design.

Production credibility: Typeahead is a polished indie utility, currently at version 2.0, sold as a one-time purchase and associated with the UIComet launch platform. It has a Product Hunt listing and an active presence on X and TikTok. No company entity, founder names, funding, or customer numbers are published, and independent validation beyond launch platforms is thin — so it is best read as a small, privacy-focused indie product rather than an established company. Its distinguishing claim, that inference is fully on-device with no telemetry, is consistent with the offline, account-free design described on the site.

Ideal Use Case

Typeahead fits Mac power users, writers, and professionals who type all day and want faster drafting with strong privacy — no cloud round-trip and no subscription. It is particularly suited to people in privacy-sensitive or regulated contexts who cannot send text to external AI servers, since the model runs entirely on-device. It is not for Windows or mobile users, and it is a narrower fit for anyone who wants grammar correction or rewriting rather than inline completion.

How Typeahead differentiates

Unlike cloud tools such as Grammarly or browser-based completions, Typeahead runs entirely on-device and works in every native macOS app rather than just the browser, with a one-time price instead of a subscription. Its privacy-first, offline, system-wide model — no account, no telemetry — is the core differentiator in a crowded autocomplete space, trading the breadth of a cloud model for locality and a flat cost.
