Ultrion is a HUD-style desktop assistant with a council of specialist agents that routes every request to the best AI for the job — then acts on it: speaks, schedules, searches the live web, sends your email, and drives your computer.
A fast classifier reads every request and hands it to the right specialist — each with its own skills and preferred engine. Ask anything; the council does the rest.
Writes, fixes and explains code with the strongest coding model available. Technical work always goes to the top of the class.
Current events, prices, scores and anything time-sensitive — answered from the live web with citations, never a stale training cutoff.
Emails, drafts, documents and anything that needs to read like you wrote it on a very good day.
Comparisons, decisions, plans and multi-step thinking — routed to a heavyweight reasoning engine.
Everyday questions answered fast on free engines — so the paid models only run when they're genuinely the best fit.
Ask Ultrion to draw, design or visualise and the Artist renders it inline, on the cheapest capable engine.
Everything below works in plain English — no syntax to learn, no menus to dig through.
Say the wake word like you'd say "Alexa". Ultrion answers in a calm, cinematic voice — hands free, on-device detection.
One-off reminders and recurring routines that fire on their own — notifications, voice, even full prompts run automatically.
Recency-sensitive questions get real web context with citations — on any model, with zero search keys configured. Paste a link and it reads the page.
Inbox summaries read aloud, and outgoing mail drafted for you. Every send shows an editable card first — nothing goes out without your approval.
Speak an event and it lands in your calendar — date, time and duration parsed for you, confirmed before it's added.
A vision-guided operator that sees your screen, clicks, types and runs commands — with a big red stop button and approval gates on anything risky.
Stuck on an error? Ask about what's on screen and Ultrion looks for itself — no copy-pasting, no describing.
Ultrion quietly learns durable facts about you — preferences, projects, people — across three editable tiers. You see everything it knows, and can erase any of it.
Build your own slash-commands: reusable instructions with a preferred engine. Your workflows, one keystroke away.
Send a request from your phone and your desktop does the work — with security modes from read-only to approve-everything.
Run a local model with Ollama for private, offline chat that costs nothing — Ultrion detects it and folds it into the council.
Bring your own API keys — they're stored locally, encrypted via your OS keychain. Run Claude on your existing Pro/Max plan with no API charges.
Add only the keys you have — Ultrion routes among whatever is connected, and prefers free engines for everyday chat to save you money.
Start free. Upgrade when you want Ultrion to take the controls.
All tiers are bring-your-own-keys — model usage is billed by your AI providers (several are free), never marked up by Ultrion. Cancel anytime.
You need at least one, but several are completely free (Groq, Google Gemini, NVIDIA NIM, OpenRouter) — no card, two-minute signup. Ultrion routes among whatever you connect and prefers free engines for everyday chat. You can also run Claude on an existing Claude Pro/Max subscription with no API charges at all.
Your API keys and email credentials live on your machine, encrypted via your OS keychain. Conversations are stored locally; signing in optionally syncs settings and memory across your devices. Ultrion never resells data, and there are no ads.
Yes — it's gated. Risky commands require explicit approval, catastrophic ones are blocked outright, there's an always-visible emergency stop, and outgoing email always shows you an editable draft before anything sends.
macOS and Windows today, with the same app and every update shipping to both. An iOS companion app pairs with your desktop for relay and remote control.
Single-model chat apps answer questions. Ultrion picks the best model for each request automatically, stays current with live web search, remembers you, and acts — reminders, routines, email, calendar, and your actual computer. It's an assistant, not a chat window.
Anytime, in one click. Downgrading keeps all your conversations, memory and settings — you only lose the paid capabilities.
Download free. Say the word. Watch it work.
