Hark Pro: What It Is and How It Compares to Muse, ChatGPT, Claude, and Gemini

What is Hark Pro, in plain terms?

Hark Pro is an AI assistant that tries to do things for you instead of just answering questions. It launched on October 6, 2026, on the web, iPhone, and Android, from Hark — a startup founded in late 2025 by serial entrepreneur Brett Adcock, best known for the humanoid-robot company Figure AI and the flying-taxi company Archer Aviation. The company raised $700 million in Series A funding at a $6 billion valuation, with Nvidia, AMD Ventures, Intel Capital, and Qualcomm participating, and Adcock personally putting in $100 million.

The pitch is ‘personal intelligence’ rather than a chatbot: Hark calls the product ‘an operating system for your life.’ You connect your email (Microsoft 365 or Google Workspace), calendar, and files; Hark remembers your preferences over time and surfaces Action Buttons — suggested tasks like approving an expense, renewing a license, booking a flight, or chasing a delivery. Tapping one hands the job to Handoff, the browser-use agent, which opens a virtual computer in the cloud and clicks through real websites the way a person would, while you watch and can stop it mid-task.

Custom Panels are the other half of the home screen: you describe a mini-app (‘track my flight refunds’) and Hark builds it, with live data from connected services. The design lead is Abidur Chowdhury, the former Apple designer behind the iPhone Air, now head of design at Hark. Dedicated Hark hardware devices are expected in 2027.

Hark Handoff: the engine underneath

Handoff is Hark's computer-use agent, first shown as a research preview in August 2026. For each request it spins up a dedicated virtual computer — its own browser, file system, and terminal — and navigates the open web end to end: ordering food, booking flights, shopping, messaging candidates. Hark's founding observation is that people spend about 75% of screen time in a browser while fewer than 1 in 1,000 websites expose public APIs, so a browser-native agent can go where integrations cannot.

On benchmarks, Hark claims Handoff scored 97.7% on the human-evaluated Online-Mind2Web test (300 tasks across 136 live sites) — ahead of an OpenAI GPT-5.4 system at 92.7% and Anthropic's Claude Opus 4.8 at 84.1%. Treat the headline ‘best ever’ framing carefully: the Online-Mind2Web result is independently evaluated, but Hark's broader comparisons ran through its own harness. On pricing the advantage is clearer and less disputed: $0.18 per million input tokens and $2.37 per million output tokens, roughly a tenth of GPT-5.5's $5/$30, with claimed 0.8-second per-turn latency. The agent can reportedly run up to 36 browsers at once to compare options in parallel.

Head-to-head: the quick table

The table below compares what each assistant is actually for. Details follow in the sections after it.

Hark Pro vs Muse AI

This is the comparison that matters most if you are choosing an agent today, because the two products rhyme. Meta's Muse AI is also an action-first agent that books, buys, and negotiates — and reporting puts its pricing at the same free / $20 / $100 ladder as Hark Pro. Citi estimates Muse could become a $27 billion business by 2030, with 6.6 million downloads and 1.8 million daily users.

The differences: Muse's commerce runs through partner checkouts (Walmart, Sephora, and others) with Meta taking a small fee per transaction, and Amazon has blocked Muse from buying on its platform. Handoff instead drives the open web directly, which reaches any site but depends on sites not blocking automation. Muse leans on Meta's ecosystem and ad-funded distribution; Hark leans on a privacy pledge — your data is yours, never sold, never to advertisers, deletable — and on being dramatically cheaper per token. Muse is further along in distribution; Hark is further along in promising you it will not monetize your data. Note the irony the market noticed: Meta built parts of Muse with Anthropic's Claude Code, then halved its internal Claude Code seats as it pushed its own tools.

Hark Pro vs ChatGPT

ChatGPT's answer to ‘do things for me’ is Dots — always-on agents launched September 29, 2026, each with its own cloud computer and browser, a standing goal, and rules for what it may do unsupervised. Dots connect to 4,000+ apps and keep working between conversations. Your first dot ships with ChatGPT Pro or Business Premium; there is no free tier at launch.

Hark Pro's equivalent is cheaper to try (free tier exists) and more proactive by default: Action Buttons push tasks at you rather than waiting for a standing goal you defined. ChatGPT counters with ecosystem gravity — 4,000+ integrations versus Hark's browser brute force — and with OpenAI's model depth behind each dot. If your life already runs through apps with clean integrations, Dots' structured approach may be tidier; if you want an agent to figure out messy websites on its own, Handoff's virtual-computer approach is the more direct bet. Both ask for real trust: connected accounts, and in Hark's case, payment cards.

Hark Pro vs Claude

Anthropic's Claude plays the same game from the enterprise side: Cowork (autonomous agent), Claude Code, and organization-wide controls, with a blockbuster IPO reportedly targeting a $2 trillion valuation. The awkward timing for Anthropic is that two of its biggest customers are now its cautionary tale — Meta and Microsoft are both cutting internal Claude spend (Meta halved Claude Code seats; Microsoft cut projected internal Anthropic spend by over a third) just as the IPO approaches.

For you as a user, the choice is temperament: Claude's agents are careful, permission-heavy, and strongest at knowledge work and coding; Hark is pushier, cheaper, and aimed at everyday consumer tasks like shopping, travel, and errands. Claude's safety posture is the industry's most conservative; Hark's is ‘watch it work and stop it anytime,’ which is transparent but puts the judgment burden on you mid-task.

Hark Pro vs Gemini

Google's Gemini is the incumbent advantage play: deeply embedded in Android, Workspace, and — via a reported $1 billion deal — Apple's Siri and Apple Intelligence. Google is also moving fast on agents of its own, and its free tier just got narrower (from October 9, free users are limited to Flash-Lite, per our daily coverage).

Hark cannot match that distribution, and it does not try. Its argument is focus: one proactive assistant that learns you, versus Gemini's sprawling presence across a dozen Google surfaces. On privacy the contrast is sharpest — Google's business is ads, and Hark's launch marketing is essentially ‘we are not Google.’ If you live in Google's ecosystem, Gemini's integrations will feel effortless; if you want an agent whose business model is subscriptions rather than attention, Hark's pitch lands harder.

Pricing compared

Hark Pro: free tier (limited usage), $20/month for 2x usage, $100/month for 10x usage. The first 100,000 signups were offered a paid plan free. Muse AI is reported at the identical ladder. ChatGPT's agent tier (Dots) requires Pro or Business Premium with no free tier. The honest way to read Hark's pricing is as an acquisition weapon: the per-token economics of Handoff (a tenth of frontier pricing) let it afford generosity that competitors cannot match yet.

Privacy and trust compared

Every agent in this comparison wants the keys to your digital life; they differ in what they promise in return. Hark's pledge has four parts: the data is yours, it is never sold, it never goes to advertisers, and you can delete it. Credentials stay encrypted from vault to website, unscrambled only on the page where needed, and you approve purchases before money moves.

Weigh that against the business models: Meta monetizes attention, Google monetizes ads, OpenAI and Anthropic monetize subscriptions and API. Hark monetizes subscriptions too — which is why the pledge is structurally believable in a way an ad company's would not be. The remaining risk is newness: Hark is a year old, its ToS necessarily grants broad permissions over email, calendars, documents, and transactions, and its safety record is unproven at scale. A privacy pledge is a promise; the vault architecture is the part you can verify.

Verdict: who should try Hark Pro?

Try Hark Pro if you want an agent that acts without being asked, you are comfortable granting deep account access to a startup, and the free tier lets you test the proposition for nothing. It is the most aggressive interpretation of the proactive-assistant idea shipping today, and its pricing undercuts everyone.

Stick with your current assistant if you are embedded in an ecosystem (Meta, Google, OpenAI) whose integrations already cover your life, or if you prefer an agent that asks permission more often than it acts. And whatever you choose, treat every benchmark claim in this space — Hark's included — as marketing until independent testing says otherwise.
