Ghost, a startup in San Francisco, has come out of stealth with a personal computer that has no display and no keyboard. The box is called Core, it sells for $3,499, and it ships at the end of October. You talk to it through a phone app, by text or voice, and it spends its time working through your email, calendar, files and smart home devices.
The company raised $11 million in a seed round led by Andreessen Horowitz. Its founder and chief executive, Zain Javaid, is 19. He argues that running models on hardware built for other purposes is a poor experience, and that an agent deserves a machine of its own.
What sits inside is a desktop-class Nvidia RTX PRO 4000 Blackwell card with 24 gigabytes of memory, running open models from the Qwen and Gemma families locally. Ghost says the models, the memory the agent builds about its owner and the processing stay on the device, that data is encrypted so the company cannot read it, and that Core keeps working if Ghost shuts down. There is no subscription.
The home page’s summary line is that no data ever leaves your home. A support page adds that the machine still needs a connection for web search, email and updates, the sort of footnote that separates a marketing claim from an architecture. Buyers will judge that difference when an agent is asked to act on something that happened online five minutes ago.
The comparison every reviewer reaches for is Apple’s Mac mini, which costs a fraction of the price and can run open models too. Javaid’s answer is that the hardware is not the product. The product, in his telling, is how the system reasons over a person’s life: what it remembers, how it decides to act, and when it chooses to reach out without being asked. Those are software problems with long tails, and they are precisely the problems a subscription competitor can iterate on every week while a $3,499 box sits on a shelf.
The device lands in a race that has crowded in a matter of months. OpenAI, Meta and xAI all have assistants competing to be the thing that runs errands for a user, and Perplexity sells a Mac-based agent at $200 a month that sorts files and reads mail. The incumbents start with distribution, a frontier model and a cloud bill they can carry. Ghost starts with a hardware margin and a fixed price.
That asymmetry cuts both ways. A company that collects no monthly fee has no recurring revenue to fund support, model updates and returns, and hardware buyers expect all three. It also has no incentive to keep a customer’s data on a server, which is the argument that sells the box. The bet is that a meaningful number of people will pay once, in cash, for control rather than capability, at a moment when capability is improving faster than privacy.
Analysts said the segment will be settled on trust rather than benchmarks. A local agent holds the keys to mail, files and devices, and a single bad action costs more than a year of subscription fees. The failure mode is not a model that is too weak. It is a model that is confident and wrong with access to everything.
Ghost’s answer is that ownership is the safeguard. If the models live on the device and the memory never leaves the house, the user can audit, unplug, or wait for a fix without asking permission from a vendor that may have already changed its terms. That is a coherent position, and it is also the position every hardware startup takes when the software is not yet the reason to buy.
The specification sheet puts real numbers behind the pitch. The card delivers 770 AI TOPS and 432 gigabytes per second of memory bandwidth, and the models listed for the box are open releases in the 27 to 31 billion parameter range. That is enough to run an agent that reads mail, drafts replies and watches a calendar. It is well short of what the frontier labs serve from data centers, and it is likely to stay short, because the gap between a local model and a hosted one has widened every year.
Ghost’s wager is that the gap matters less than the access. An assistant that never sends a document to a third party can be pointed at a tax return, a contract or a medical record, and the things people most want handled are exactly the things they least want uploaded. The company is selling permission as much as capability, which is a harder product to demo and a stickier one to own.
Reviewers have raised a harder question. Continuous context, the feature that makes an always-on agent feel useful, requires a stream of personal data and a habit of granting access. Users who tolerate that arrangement may not care where the models run, and users who care may not tolerate the arrangement. The price of the box buys both sides of that argument at once.
The coming months will test something narrower and more measurable. Ghost promises a machine that keeps working if the company fails, which is unusual honesty and an unusual promise to keep without recurring revenue. The first thousand buyers will decide whether a screenless box in the corner earns its place, or becomes the neatest example yet of a computer designed for a product that has not arrived.
