    Most assistants wait to be asked. Cressida remembers the interview you mentioned on Monday, notices when it moves, and asks before she changes a thing. And when you’d rather she kept quiet, she does. Mostly.

    One sentence, all the way through

    “Hey Cressida, remind me to call Mom after my last meeting.”

    Illustration · an example sentence, not a recording

    1. Voice She hears her name, then the rest of the sentence: “remind me to call Mom after my last meeting.”
    2. Memory She checks what she already knows. Mom is in your contacts, and your last meeting ends at 4:30 PM.
    3. Tasks Those two things become one reminder: call Mom at 4:40 PM.
    4. You It’s all arranged around you, and she answers: “Done. I’ll remind you to call Mom at 4:40, just after your last meeting.”

    Nine things she already does

    On the Mac, in development today. The lines are written examples.

    1. 01

      Hears her name

      Say “Cressida” and she’s there, from across the room. She listens for it on the Mac itself.

      “Cressida, what’s next?”
    2. 02

      Remembers, visibly

      What you mention in passing, kept where you can see, correct and delete it.

      “You said Sam still owes you the budget figures.”
    3. 03

      Keeps plans in step

      When something moves, she finds what depends on it and asks before touching it.

      “Shall I move your prep to Sunday?”
    4. 04

      Watches for replies

      Tell her who you’re waiting on. She notices when they answer and offers the next step.

      “Sam got back to you. Send the budget now?”
    5. 05

      Holds your place

      Interrupted mid-thought? Ask where you were and she hands you the thread.

      “You were halfway through the proposal intro.”
    6. 06

      Knows when to hush

      Quiet hours, focus, and “I have company” - one sentence, and she behaves.

      “Understood. Only if it’s on fire.”
    7. 07

      Rehearses with you

      Practise the interview or the awkward call. She plays the other side and tells you how it went.

      “Again, but slower on the second answer.”
    8. 08

      Writes to future you

      Leave a note for next week’s you. She delivers it at the right moment.

      “A message from Tuesday: you’ve got this.”
    9. 09

      Guards what matters

      Tell her what matters this week. She flags what works against it, then leaves the choice to you.

      “You wanted mornings kept for the demo. Set it anyway?”

    Everything you mention, in one place

    Drag it round. Every note shows where it came from, and you can correct or delete any of them.

    Example memories · sample data, not anyone’s real notes

    Tell her once. She’ll keep it, move it, mention it, and when you’d rather, say nothing at all.

    When the plan changes, she keeps up.

    Tell her once. She connects it to everything that depends on it, and asks before she changes anything.

    1. Monday, 7:40 PM

      My interview with the VP is on Friday.

    2. She keeps it, and what hangs off it

      Listening for “Cressida”

      Ask her

      Stay in charge

      What’s ready

      Cressida isn’t available yet. Today, only her developer uses her. Here’s exactly where things stand.

      Working in developmentMac

      • Talk by saying “Cressida”, or type
      • Her own voice, and you can interrupt her
      • Memory you can see, correct and delete
      • Plans that change: linked reminders and follow-ups, with your OK
      • Reminders synced to Apple Reminders
      • Calendar, tasks and who you’re waiting on
      • Email announcements you control by sender, kind and time
      • Quiet hours, focus and “I have company”
      • Rehearsals, routines you teach her, messages to your future self
      • Priorities she guards: what matters this week, and time kept free for it

      In developmentiPhone

      • An iPhone app sharing one conversation with your Mac
      • Talk from your phone while your Mac does the thinking
      • Notifications when you’re away from your Mac

      Planned

      • A public release for Mac and iPhone
      • Accounts, so she works without your Mac switched on

      No Android version is planned for now.

      1. 01 / Listen

        Listening for her name

        Until she hears “Cressida”, nothing you say leaves your Mac. The listening happens on the Mac itself.

        • Wake word on this Mac
        • Microphone off whenever you like
        • Nothing sent before her name
      2. 02 / Hear

        Hearing you

        What you say becomes text on your Mac when her local speech model is ready, and through OpenAI when it isn’t.

        • Talk or type
        • Interrupt her any time
      3. 03 / Think

        Thinking it through

        Your request and the notes that matter to it go to OpenAI, so she answers with context instead of guesswork.

        • Only the notes that matter
        • Asks before changing plans
      4. 04 / Remember

        Remembering

        What’s worth keeping becomes a note in a file on your Mac: where it came from, how long it’s kept, and what relies on it.

        • See it
        • Correct it
        • Delete it
      5. 05 / Speak

        Speaking up

        Her voice is generated by OpenAI and streamed as it’s made, so she starts talking almost at once.

        • Quiet hours and focus
        • “I have company”
      6. 06 / Parts

        What she’s made of

        Six parts, each with one job, and you can see exactly where every one of them runs.

      What she hears, and where it goes

      In plain words, as the Mac app works today.

      The microphone
      On your Mac, she listens for her name on the Mac itself. Until she hears it, nothing you say leaves your Mac. On iPhone, you tap to talk. You can switch her microphone off at any time.
      After her name
      What you say is turned into text on your Mac when her local speech model is ready, and by OpenAI when it isn’t.
      Her replies
      To answer, your request and the notes that matter to it are sent to OpenAI. Her voice is generated by OpenAI too.
      What stays on your Mac
      Memories, reminders, settings and your conversation history are files on your own Mac.
      Email and calendar
      Only if you connect them. She reads them on your Mac to announce, summarise and follow up.
      Your controls
      See, correct or delete anything she remembers, or turn memory off. Quiet hours, focus, “don’t follow up on this” and “I have company” are one sentence away.

      Questions

      When can I get Cressida?

      Not yet. She’s in private development on Mac, and the iPhone app is in development. Join the waitlist and you’ll hear the moment there’s a place.

      Is the voice on this page live AI?

      No. The clip is Cressida’s real voice reading a short script. The conversations are written examples, and the app screens are real, shown with sample data.

      Is she always listening?

      On your Mac she listens for her name, on the Mac itself, and only acts when she hears it. On iPhone you tap to talk. You can turn her microphone off whenever you like.

      What does she remember?

      What you tell her that’s worth keeping, plus the odd guess, clearly marked as a guess. You can see all of it and what relies on each note, correct it, have her forget it, or turn memory off.

      Will she change my plans on her own?

      No. When something changes, she proposes the knock-on changes and asks first. A single small change can be made straight away, with an undo.

      How much will it cost?

      That hasn’t been decided. The waitlist is free and commits you to nothing.
