No credit card. Your own app on your phone and your PC — not a chatbot stuck on this website.
HOW IT WORKS

You install your own Jarvis — on both your devices.

This isn't a "stronger AI" you rent on our homepage like some chatbots. When you subscribe you install your own Jarvis app — one on your phone, one on your PC — sign in once, and it's yours on both. Your conversations and memory follow you between them.

📱
Phone app Install to your home screen — full-screen, no app store.
💻
PC / desktop app Install it on your computer too — same login, wider command center.

The thinking runs securely in the cloud, so it's the same Jarvis everywhere you sign in — and it works even on a brand-new device the moment you log in.

Jarvis

Witty, unflappable, endlessly capable. Plans your day, drafts your words, untangles problems, and explains anything — with charm and a dry sense of humour.

Ultron

Cold, precise, strategic. Stress-tests your ideas, hunts the weakness in any plan, and tells you the hard truth others won't. A red-team mind on demand.

A whole team of brains.

Paid plans unlock three more specialists alongside Jarvis & Ultron — each with its own focus and its own memory. Switch between them with a tap.

Ledger · CommercePricing, margins, fees, listings and cash flow for your own business — grounded in real numbers.
Muse · MarketingHooks, copy, content calendars and growth tactics, with ready-to-use words, not vague advice.
Atlas · StrategyRoadmaps, prioritisation and where to spend your time and money for the biggest compounding return.

Not just a chatbot — an assistant that acts.

On paid plans every brain uses real tools — so they look things up, work out exact numbers, and remember you, instead of guessing.

🔍 Live web searchLooks up current facts, news, prices and people on the real web — then reads the page for the details.
🧮 Exact math & datesRuns a real calculator and knows today's date, so numbers and "how long until…" answers are correct.
🧠 Learns & remembers youBuilds a private long-term memory of who you are and what you're working on — and gets more useful every chat.
🗂️ Personal workspaceArchitect: your own projects & tasks that Jarvis keeps up to date as you talk — your private command center.
Voice built inTalk to it and hear it reply, hands-free, right from your phone.
Installs on phone & PCAdd it to your phone's home screen and install it on your computer — same account, both devices, no app store.

Honest note: Jarvis is a cloud assistant that researches, reasons, calculates and remembers — it doesn't log into your private accounts or control your devices. The free Observer tier is conversation only; web, tools and learning memory are on the paid plans.
