What is osmos assistant?
osmos assistant is an AI super-app for iPhone: a personal agent you talk to in one chat. Connect your email, calendar, WhatsApp, Slack and other apps, and it answers questions, drafts replies, books travel, keeps your reminders and runs routines for you, including jobs it carries on with after you've closed the app.
How is osmos different from ChatGPT or Siri?
Three things. It remembers what you tell it and what it learns from your connected accounts, so you don't repeat yourself. It works on its own: routines run on a schedule, follow-ups check back later, and the Home card surfaces what needs you. And it acts: it books flights, hotels and trains with your approval, and has its own computer for jobs on the web.
See osmos vs ChatGPT and osmos vs Siri.
Is osmos free?
osmos is free to download and includes a one-time trial of 200 credits and 30 minutes of Computer Use. Paid plans (Plus, Pro and Max) add 1,500, 3,000 or 8,000 credits a month, plus features such as WhatsApp, third-party tools and more computer time. Prices are shown in the app for your country and billed through the App Store.
Does osmos do things without asking?
No. Spending money, sending a message it wasn't asked to send, deleting or overwriting things in a connected tool, and typing passwords, card numbers or codes always come back to you. Bookings are held first and only confirmed when you approve.
Is my data safe?
Your data is stored encrypted, in the EU, and access is limited to your account. To think, osmos sends only the relevant parts of a request to AI model providers that don't retain or train on it. Your data is never sold, never used for advertising and never used to train models, and you can export or delete all of it from Core → Profile.
Your agent is waiting.
Free to start. You approve every action. It gets better the longer you talk to it.
