How it works

Three steps. About a minute.

  1. 1

    Download

    One file, no account. Open it and it fetches its local AI model once. After that, everything runs on your Mac.

  2. 2

    Allow Accessibility

    macOS asks once. It lets Highlightr see the field you're typing in, so help shows up at your cursor.

  3. 3⇥

    Start typing

    Grey text appears as you write. Press Tab to keep it. That's the whole lesson.

Privacy

Your words never leave your Mac.

Client emails, contracts, patient notes. Write them with help, without pasting them into someone else's cloud.

What testers say

I cancelled three subscriptions the week I installed it. The autocomplete in Mail already sounds like me.
LLena K.Freelance designer, Berlin
English isn't my first language and I write to clients all day. It catches what I miss, and nothing goes to a server.
MMarco R.Sales lead, Milan
No bot joining my client calls, and a clean summary when we hang up. That alone was worth it.
PPriya S.Management consultant, London
I dictate first drafts on walks now. It's the first speech to text I don't have to clean up after.
JJonas W.Copywriter, Hamburg
I can't paste client text into a chatbot. This is the first AI writing tool I'm actually allowed to use.
CClaire D.Lawyer, Paris
Works in Slack, Notion and Word without a single plugin. I forget it's a separate app.
TTom B.Startup founder, Amsterdam
Try it free until the end of the year.
