Frequently asked questions
What is Zen?
Zen is a personal assistant from Carreh. It reads your email and keeps your bills, parcels, trips, appointments and to-dos in order, and reminds you at the right time.
How does Zen work?
You connect your email. Zen reads new mail every 15 minutes, picks out what matters and puts it in the right place in the app. You can also chat with Zen, send voice notes and upload documents.
Which email accounts can I connect?
Gmail, Outlook and IONOS. You can connect more than one, as long as they are your own addresses.
Does Zen connect to my other accounts?
No. Zen works from your email and from what you tell it or upload. Nothing else.
Can Zen send emails or pay for me?
Zen can draft an email, but it only sends it when you tap Approve & send. Zen never pays or moves money. It never deletes anything without your OK either.
What can Zen do for me?
Track bills and remind you before they are due, track parcels live, turn booking emails into trips, keep health appointments and refills, run errands like cancellations and refunds, help you learn, and make PDF, Word and Excel documents.
What won't Zen do?
Zen won't pay, send or delete without your OK, make phone calls, or give medical, legal or financial advice. When only a call works, it writes you a call script.
What are Zennies?
Zennies are the helpers on your Zen team. Each one looks after an area of your life and has its own chat, memory and tasks. You can create, edit and pause them.
Can I bring what another AI knows about me?
Yes. In Settings > Memory > Import from another AI, paste what ChatGPT, Gemini or another assistant remembers, or upload its export. You choose every fact before it is saved, the file is deleted once read, and one Undo takes the whole import back out.
How do I see what Zen is doing?
The Tasks tab shows every task, which Zennie owns it and how far it is. Every change is in Activity, with Undo.
Can I undo something Zen did?
Yes. Every change Zen or a Zennie makes is logged in Activity with an Undo button. Deleted items can be restored for 30 days.
Does Zen give medical advice?
No. Zen keeps track and reminds you. It doesn't give medical advice, and it never interprets results or suggests treatment.
Is my data private?
Mailbox sign-ins are stored encrypted, personal details stay hidden until you unlock with Face ID or your PIN, and health details never appear in notifications. Zen does not delete or move your email.
What AI is Zen?
Zen is Carreh's own AI assistant, built in-house by Carreh. Its memory, Zennies, routines and safety rules have been developed and refined through months of daily use, and it is checked every day against Carreh's own test of real tasks. For each task, Zen picks from several leading AI models so it can use the right one for the job. Carreh keeps the details of how Zen works private.
How do I delete my data?
Write to the Zen team at zen@carreh.com or from Help & support in the app.
Which devices does Zen work on?
iPhone and iPad. Everything is kept in your account, so a change on one device shows on the others straight away.
How do I sign in?
With your Carreh account. Then you unlock Zen with Face ID, a passkey or a PIN.
How much does Zen cost?
Zen One is €30 a month. Zen Extra is €200 a month and gives you 20 times the usage of Zen One.
Is there a free plan?
No. Zen has two paid plans, Zen One and Zen Extra.
What happens when I reach my weekly usage?
Zen's replies and your Zennies' tasks wait until the weekly reset, Monday at 06:00 Paris time. Your reminders and everything you saved keep working.
When can I use Zen?
Zen isn't open to the public yet. It's coming soon: join the waitlist and we'll let you know when it opens.
How do I get help?
Open Help & support in the app's Settings, or email zen@carreh.com.
Is my data used to train Zen's AI?
Only if you say yes. Help improve Zen is off until you turn it on. When it is on, Carreh may use your chats, actions and documents to improve Zen. We only use data from the time it was on. Change it any time in Settings, Privacy.
Can Carreh staff read my conversations?
A small number of staff may, to keep Zen safe: for example to check a report or stop abuse. This applies to everyone. Every look is logged, and it is never used for training unless you turned on Help improve Zen.
How do I get a copy of my data or delete it?
Email zen@carreh.com or write from Help & support in the app. We can send you a copy or delete your account and its data.
