Works in every Mac app.

From your email to your editor. Slack to Notion. If you can type in it, TypeAssist works.

Native surface

A typing assistant only works when it disappears into macOS.

Most AI writing tools live in their own window. TypeAssist lives in every text field — Mail, Notes, Linear, Slack, Notion, your terminal. It reads what's already there, suggests in line, and stays out of the way until you press Tab.

Reads what you're working on

TypeAssist looks at the text around your cursor and the app you're in before suggesting anything — so completions match the sentence you're actually writing.

100% on-device

Runs entirely on your Mac with Apple Silicon's Metal GPU and open-source models. Your writing never leaves the device — no cloud round-trip, no telemetry, no waiting on someone else's server.

Tab to accept, anywhere

Ghost text appears right at the cursor in any text field — Mail, Notes, Slack, VS Code, Notion, Terminal. Press Tab to accept; keep typing to ignore.

Completion pipeline

From cursor context to accepted text.

Every step happens in under 200 milliseconds, on your Mac, every time you pause typing. No prompts to write, no chat window to switch to, no copy-paste shuffle between apps.

01

Capture

Accessibility APIs read the focused text field and current cursor range.

02

Assemble

Prompt templates blend surrounding text, custom instructions, and tier-gated context.

03

Generate

Local base or instruct models predict the next phrase with cache reuse and branch search.

04

Render

Ghost text appears at the cursor and accepts through Tab without breaking the target app.

Why TypeAssist

Different by design.

Built for writing, not chatting. Base models trained on raw text predict what you'd say next instead of formatting a reply.

One payment, every Mac you own. No subscriptions, no renewals, no logging in to keep what you already bought.

Lives in every text field on macOS. Works the same in Mail, Linear, Notion, Slack, VS Code, Terminal — without any plugin or extension.

Pay once. Type faster on every Mac you own.

Drop your email and we'll send the download link the day TypeAssist launches, plus an early-supporter discount on the lifetime license. No spam, no marketing drip.
