It’s 11:40 on a Tuesday night. You’ve got a tax document open, a half-finished message to your landlord, and a folder of medical PDFs you’d rather not think about. You want something to sort through all of it. So you open a chat window, hover over the upload button, and then stop — because you have no real idea where that file goes once you let go of it.
That hesitation is the whole product thesis behind Hark Pro.
Hark, founded by Brett Adcock, released its AI personal assistant in 2026 with privacy as the headline feature. The assistant is designed to run on users’ own computers, and the company has said it plans to release an AI-native device in 2027. Hark raised $700 million in a Series A at a $6 billion post-money valuation to build a consumer-focused universal assistant powered by proprietary multi-modal models and custom hardware. The stated long-term goal is an operating system for AI computers.
That’s the available information. I want to be upfront that it’s thin for a product review, so what follows is analysis rather than a verdict.
Why the local-first angle actually matters
Every assistant that’s tried to become a daily habit — Muse, Instinct, Dots, the whole crowd TechCrunch grouped together — has run into the same wall. To be useful, an assistant needs access to your stuff. Your calendar, your files, your messages, your half-written drafts. And the more access it gets, the more you have to care about where that data lands.
Most products answer this with policy. Certifications, permission controls, governance dashboards, a page explaining retention windows. Those things matter, and in a work context they’re often the deciding factor. But they’re all promises about what a company does with data it already has.
Running on your machine is a structurally different answer. If the processing happens locally, there’s less to promise. That’s a meaningfully stronger position than a well-written privacy policy, and it’s the one piece of Hark’s pitch I’d call genuinely interesting rather than just well-funded.
What I’d want to test before believing any of it
“Privacy-first deployment” covers an enormous range of actual architectures, and the gap between them is where reviews live or die. Questions I’d put to Hark Pro on a test machine:
- What runs locally and what doesn’t? Most local-first assistants still route harder requests to a server. If that’s happening, I want to see exactly when, and I want to be able to turn it off.
- What does it cost your laptop? Local inference means your fan, your battery, your RAM. A capable assistant that makes your machine unusable during a video call isn’t a trade most people will take twice.
- How good is it when it’s offline? This is the honest benchmark. If quality collapses without a network connection, the privacy story is marketing rather than architecture.
- Can I verify any of it? Network monitoring, open components, third-party audit — something beyond a claim on a landing page.
None of those are hostile questions. They’re the standard ones, and the answers tend to separate real local-first tools from cloud products wearing a privacy badge.
The hardware bet is the part I’d watch
The 2027 device plan is where this stops being a software review and becomes something stranger. Custom hardware plus proprietary multi-modal models plus the ambition to build an operating system for AI computers — that’s a platform play, not an app. Pitched that way, the $6 billion valuation makes more sense than it would for a desktop assistant.
It also means the software you can use today is almost certainly a staging ground for something else. That’s not a knock, but it should shape your expectations. Early access to a platform-in-progress usually means rough edges and shifting features, and sometimes the thing you learned to depend on gets rebuilt around hardware you don’t own.
Where I land for now
If your work involves files you’d rather not hand to a server — client records, health data, anything under an NDA — a local-first assistant is worth your attention, and Hark Pro has more funding behind that idea than anyone else currently chasing it. There’s also a real open-source scene in this space if you’re comfortable with setup work and want the architecture fully visible.
If you just want an assistant that handles your calendar well, the privacy angle probably won’t be the thing that wins you over, and you’ve got plenty of more mature options.
My plan is to get Hark Pro on a test machine, watch its network traffic, and report what the offline experience actually feels like. A $700 million Series A buys attention. It doesn’t buy a passing grade.
