Hy

An AI email assistant that knows what needs an answer

Hy is an AI agent for your phone. Connect your mailbox once, and Hy reads along: it tells you which messages need you today, sums up long threads and drafts replies in your tone. Sending stays your call.

Things to ask Hy

  • “What came in that needs an answer today?”
  • “Summarize the long thread from Marta”
  • “Draft a friendly reply to Ben and say Thursday works”
  • “Find the invoice the agency sent last month”

What Hy does with your email

  • Spots what needs you: when you turn on proactive messages, Hy looks through your mail every half hour, in the cloud, even while the app is closed, and tells you in the chat when something needs you, with a short reason why now.
  • Prepares the work: when the mail supports it, Hy drafts a reply before it notifies you, so you only have to read, edit and approve.
  • Answers questions about your inbox: ask for a message, a date, an attachment or what someone wrote, in plain words.
  • Summarizes threads and attachments: a long thread or a PDF becomes a few lines you can act on.
  • Skips the noise: routine verification emails are left out, and old mail only comes back when a deadline or risk is still open.

Works with the mailboxes you already have

Gmail through your Google account, Outlook through Microsoft 365, and other mailboxes such as GMX, WEB.DE, T-Online or iCloud Mail. You choose each connection in the app under Connectors and can disconnect any time.

You decide how often Hy asks

In Settings → Approvals you choose how Hy acts on your behalf. With Always ask, you review every change before it runs: you see what Hy wants to do and why, and nothing happens until you tap Allow. With Risky actions, routine work goes ahead and Hy asks before anything risky or destructive. You can also give standing permissions for things you do often.

Approvals lists every request next to what Hy did and what is coming up, so you can always see what happened.

Your mail, your data

Hy asks for your consent before your messages go to AI services, and explains which providers process them. Your Hy workspace is stored in Germany by HybridAI, a German company. You can delete what Hy remembers about you, one memory at a time, or delete your whole account from Settings.

Questions

Does Hy send emails without asking?
Only if you allow it. With Always ask, Hy shows you every email before it goes out. With Risky actions or a standing permission, routine work can run without a prompt. You set this in Settings → Approvals.
Which email providers does Hy support?
Gmail, Outlook and other Microsoft 365 mailboxes, and mailboxes such as GMX, WEB.DE, T-Online or iCloud Mail.
Does Hy work while the app is closed?
Yes. Proactive checks run in your HybridAI cloud account every half hour, so Hy can tell you about a mail even when you haven't opened the app.
