Sipher AI chat

Ask Sipher AI about your inbox, look up people, extract tasks, get a morning brief and draft messages. It never sends without your tap.

Sipher AI chat is an assistant that can read your mailbox when you allow it and answer in plain language.

Open it#

  • Web: choose Sipher AI in the sidebar for the full chat page. Inside an open thread, click the Sipher AI sparkle button in the thread toolbar to chat about that conversation.
  • iPhone and Android: open the Sipher AI tab.

In a thread, three suggestion chips appear: Summarize this thread, Extract action items and Draft a reply.

What you can ask#

RequestWhat you get
Inbox searchMatching emails, for example invoices from last month
Person lookupEmails from and to a person, and a contact card
Task extractionAction items and deadlines found in your mail
Morning briefUnread count, priority emails, follow-ups due
DraftsA draft message based on your request or a thread

Replies can cite the emails they used, so you can open the source.

Actions need your confirmation#

Sipher AI cannot change your mailbox on its own. When you ask it to archive, label, snooze, add a calendar event or set a reminder, it shows a card. Nothing happens until you tap to confirm.

Sending an email#

  1. Ask Sipher AI to write and send a message.
  2. It shows the draft on a card.
  3. Ask for changes, or tap Send.

If you ask for a later time, the card shows the send time. You still confirm it. Sipher AI never sends without you tapping Send.

What it reads#

Searching your inbox depends on the allow inbox read preference. If it is off, Sipher AI cannot search your mail for answers. In privacy mode the chat is unavailable.

Chat messages use AI credits. Sipher AI can also use memories you have saved.
