The personal agent for founders & CEOs · Built in Europe
Prio works through your email, calendar and documents around the clock, in Outlook or Gmail. It answers, schedules, preps your meetings and chases every follow-up. Nothing is sent until you sign off. EU-hosted, GDPR-compliant.
How much Prio does on its own is your decision, made on its track record. Nothing changes until you say yes.
01
It asks first
From day one
Every email, invite and reply with your name on it waits for your approval. You see the full draft and approve, edit or reject it.
02
It asks to do more
20 decisions · 80% yes
Once you've decided on the same kind of work 20 times in 90 days and said yes at least 80% of the time, Prio asks whether it may prepare the next ones on its own. You still confirm before anything is sent. Say no, and it won't ask again.

May I prepare your meeting briefs myself from now on?
Yes, prepare themKeep asking
03
You decide who skips the queue
Your call
Mark people you trust as always allowed. Small internal steps, like a note in your CRM or an event only you attend, Prio already does without asking.
Never on its own
Public posts and phone calls always ask first. Every permission can be taken back in Settings.
Any model can write the email.Prio knows who it's for.
Memory
The model is the easy part. What makes a draft right is what Prio has learned about your people, the way you write and the year behind you. That grows every week you use it.
01
What you tell it
Mention something once and it stays. Months later Prio finds it by what it meant, not by the words you used.
02
How you write
Every edit you make to a draft teaches it your style. Reject one and say why, and that becomes a rule for the next.
03
Who matters
From how you correspond, Prio works out who your important people are. Their mail gets a draft first, and nothing goes to them without your OK.
04
What happened last year
Prio remembers what it did, and for whom. When the birthday, the renewal or the board dinner comes round again, last year is already on the table.

Priya will ask about burn, not growth.
Prio · Board prep with Priya Raman · 45 min
Her last two emails were about runway. Q3 burn came in 12% over plan after the two senior hires, and the board pack does not explain it yet. Lucas's pipeline update moves the Halden renewal into Q4.

What I did
Pulled the Q3 numbers from the board pack, found the two open asks in last quarter's minutes, and proposed moving your 1:1 with Lucas so you have time to read. The move waits for your signature.

“I built Prio for my own inbox first. Every morning it shows me what came in overnight, what it has already prepared, and what is waiting for my signature.”
Fred van RijswijkFounder of Prio
We run our own company on Prio, through the same approval queue you get. Nothing goes out with my name on it until I have read it.
Pays for itself with one rescheduled meeting per month
Pricing
A human assistant costs €3,500 a month — Prio starts at €29. No annual contracts, no hidden fees. Free for 14 days — cancel anytime before billing starts.
Prio connects to Outlook or Gmail via OAuth. It reads incoming email, sorts it by urgency, drafts replies in your tone and archives noise like newsletters. Nothing is sent without your explicit approval.
Does Prio work with Microsoft 365?
Yes. Prio works with Outlook mail, Outlook Calendar and OneDrive, and replies go out from your own Outlook address. Gmail and Google Calendar work too. Connect via OAuth from the integrations page.
How is Prio different from ChatGPT, OpenAI Dots or Meta Muse?
ChatGPT, Dots and Muse are general-purpose. At launch (September 2026), OpenAI doesn't offer Dots on ChatGPT Pro in the EEA, the UK or Switzerland, and Muse launched in the US only. Prio does one job, the work of a chief of staff, for founders and executives in Europe: in Outlook or Gmail, in your own language, hosted in the EU. Nothing is sent without your approval.
Is my data safe?
Yes. All data is hosted in EU data centers, encrypted in transit and at rest. We never use your data to train AI models. We're GDPR compliant and working toward SOC 2 certification.
What integrations do you support?
Outlook, Outlook Calendar, OneDrive, Gmail, Google Calendar, Google Drive, Slack, Notion, GitHub, LinkedIn, Attio and Moneybird today, with more shipping monthly. We also support MCP, the open protocol, so any compatible tool works with Prio.
Can I try before I pay?
Yes. Every plan starts with a 14-day free trial — you add a card but nothing is charged until day 14, and you can cancel anytime before then. After the trial there's still a 30-day money-back guarantee: if Prio isn't for you, request a refund from Settings → Billing and get every cent back.
Do you support languages other than English?
Yes. Prio works in English, Dutch, German, and French — the site, the app, and the AI itself. Briefings, drafts, and replies come in your language natively.
How much does Prio cost?
Plans start at €29/month for Starter (30 requests a day, email triage, calendar, tasks). Pro is €79/month with 100 requests a day, smart scheduling and workflow automations. Business is €199/month with unlimited requests and multi-platform bot support. All plans start with a 14-day free trial.
How does the approval system work?
By default, emails and invites wait for your approval: you see the full draft and approve, edit or reject it. Small internal steps, like a note in your CRM or an event only you attend, Prio can do on its own. You can mark people you trust as pre-approved. Public posts and phone calls always ask first.
Does Prio work on mobile?
Yes. Prio works in the browser on any device, including your phone, with voice input to dictate tasks, emails and commands. The native iPhone app, with notifications you can approve from, a Today widget and Siri, is in public beta: join through TestFlight at testflight.apple.com/join/GR5hgt1m.
What happens to my data if I cancel?
Your data stays available for 30 days after cancellation so you can export everything. After that, it's permanently deleted from our EU servers. No hidden copies, no retention.
What other tools does Prio connect to?
Beyond email and calendar, Prio connects to Google Drive, Slack, Notion, LinkedIn, Moneybird, and Microsoft OneDrive. We also support MCP — the open protocol — so any compatible tool works with Prio.
