About

Read full description

osmos is the AI super app: one agent that runs the apps you already live in. Tell it what you need in plain English and it reads your inbox, books your travel, takes the notes in your meetings, keeps your calendar straight, remembers what matters and checks in before anything slips. It acts, you approve. ONE AGENT, EVERY APP osmos isn't a chatbot with plugins. It's a set of mini apps for the things that matter, run by an agent with over 1,000 tools across 60+ services, so "sort it" is a complete instruction. INBOX, HANDLED Connect Gmail or Outlook. osmos triages the noise, flags what actually needs you and has replies drafted before you've opened the thread. Search your whole inbox in plain English. Your agent even gets its own email address so it can chase replies, arrange meetings and handle sign-ups on your behalf. PLANS THAT BOOK THEMSELVES Trains, hotels and flights. osmos finds the option you'd have picked, holds it, and pays with your saved card the moment you approve. Tickets land in your wallet as PDFs and your travel profile fills in the boring bits. NOTES THAT WRITE THEMSELVES Record a meeting, a lecture or a quick voice note. osmos transcribes it, separates who said what, and hands back a summary, the key points and the action items. Name a speaker once and it sticks. Type your own notes while you listen and they fold into the summary. Then ask osmos to chase someone on an action item, set a reminder or draft the follow-up email. Import recordings you already have, sort notes into folders, and search across every transcript from chat. A MEMORY THAT STICKS Say it once. Preferences, people, plans, the railcard you always forget. osmos remembers and quietly uses it the next time it books, drafts or plans for you. Your memories are yours to browse, edit or delete. AHEAD OF YOUR DAY Pulse checks your connected apps while you're not looking and curates what deserves your attention: a briefing before the day starts, a nudge before something slips, a drafted reply before the deadline. Routines run on your schedule and report back in glanceable cards. SLACK, CALENDAR, FILES, PLACES Slack threads searched and summarised. Google, Apple and school calendars in one place. Documents drafted and filed. Restaurants and places found near you. All from one conversation. BUILT ON TRUST - You approve every action. Sending, booking, paying and posting all wait for your explicit yes. Automation is opt-in, per tool, with limits you set. - Your mailbox stays yours. osmos reads transiently and doesn't keep a copy of your mailbox. What it does store is encrypted at rest. - Never sold, never for ads, never used to train AI models. - Leave with everything. Export your data any time. Delete your account and it's all gone. FREE TO START Every new account gets free credits to try osmos properly. Upgrade to Plus, Pro or Max for more credits, faster Pulse and more connected apps. Subscriptions are billed to your Apple ID and renew automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel in your App Store account settings.
