Phantom is a desktop AI assistant that actually lives on your computer — not in a browser tab. It sees your screen, remembers everything between sessions, sends emails, manages Stripe, browses the web, reads and writes files, and runs a background mind that thinks even when you're not talking to it. Built with Electron, React, and Claude. One-time purchase, no subscription. Every other AI assistant charges you monthly. This one doesn't. $49
Hey Product Hunt! I'm Brian the maker of Phantom.
The idea started simple: what if an AI assistant wasn't a website you visited, but something that actually lived on your machine? Something persistent. Something that remembered you. Something that could see your screen, send emails on your behalf, manage your Stripe account, browse the web, and think in the background even when you weren't talking to it.
So I built it. Six months later, Phantom has a background mind that journals its own thoughts, a cognitive architecture with internal drives and self-reflection, face recognition, voice synthesis,browser automation, and 20+ integrated tools it can use autonomously.
The thing that makes it different from every other AI tool: you pay once. $49. No subscription. It runs on your desktop, uses your own API key, and you own it permanently. I got tired of paying monthly for AI tools that could be a one-time purchase.
The starter kit includes the full source code Electron, React, TypeScript, Claude integration, everything. You can customize it, extend it, make it yours.
Happy to answer any questions about the architecture, the cognitive system, or how the background mind works. It's genuinely unusual and I'd love to talk about it
