For investors

Why Harf.
Why now.

The problem
Work gets scattered across apps. Every task means switching windows and repeating context.
The approach
Say what you need once. Harf uses what’s on your screen as context and acts inside the app. AI can now read a screen and take action; Harf puts that one sentence away on the Mac.
Working today
Recorded demos: a first cut in Premiere Pro, an explanation drawn on screen, and a portrait painted in Krita.
What’s next
Early access on people’s own Macs, starting with these three workflows. Then more apps, chosen by what early users ask Harf to do first.

Frequently asked questions

Can I try Harf today?

Not publicly yet. Harf runs as a working private demo. Request early access and we’ll email your invite when a spot opens. There is no public installer on this website.

What happens in a private demo?

It’s a 20-minute walkthrough with the founder: see the product, explore a workflow, and ask questions. You don’t need to join the email list to book.

Which emails will I receive?

Your invite when a spot opens, and occasional product news. You can unsubscribe at any time, and messaging the founder won’t add you to the list.

Does joining the list give Harf access to my Mac?

No. Joining the list does not install Harf or grant access to your Mac. The signup form asks only for your email address and the updates you want to receive.

What permissions will Harf need?

The access needed depends on the workflow and apps involved. In a private demo, ask which macOS permissions are required, what each one allows, and how access can be revoked before trying Harf with your own work.

Where are my screen and voice data processed?

A detailed data-flow and retention policy is not published on this website yet. Before sharing confidential material, ask the founder what leaves your Mac, who processes it, and how long it is retained.

Can I see a demo without sharing sensitive work?

Ask for a walkthrough using sample data. You do not need to share passwords, client files, or confidential screens to discuss what you want Harf to help with.
