Some people seem on top of everything. They have help.

Text it like a friend. It lives in your Messages, speaks up first, and already knows what's in your account.

It can see your money. It can't touch it.

Assistants got good. They draft the email and move the meeting. But ask one whether you can afford the trip and it guesses, because it has never seen your money. Harper has. That is the whole difference.

Harper finds the difference in your first week.

No new app.
It texts you.

Harper lives in your Messages and speaks up first. A brief in the morning, a heads up when something big clears, an answer whenever you ask. Reply like you would to a friend.

  • Answers in your real numbers, not estimates
  • Flags a charge that is far bigger than your usual
  • Tells you when the balance is getting thin
  • Text it "stop the daily one" and it stops

It works
where you already work.

Connect an account once and Harper works inside it. It reads on its own. Anything it wants to write, it shows you first and waits for a yes.

  • Gmail

    Finds the thread you can't find. Writes the reply and leaves it in drafts, so you are the one who sends it.

  • Google Calendar

    Reads what's coming. Adds something once you say yes to it.

  • Notion

    Files the note where you would have filed it, and finds the page you only half remember.

  • Slack

    Catches the thing you were tagged in and has an answer ready before it goes cold.

  • Linear

    Opens the issue from a sentence, and closes it when you say it is done.

  • GitHub

    Watches the pull request and nudges the reviewer so you do not have to.

Your accounts connect through Plaid, read-only. More tools land every week.

Fair questions.

What can Harper actually do?

Answer anything about your own money in real numbers. Find what repeats every month and what it costs you a year. Text you a morning brief, a weekly recap, and a heads up when a charge is far bigger than your usual or the balance is running thin. Search your Gmail, read your calendar, and write drafts and events for you to approve.

Which tools can it use today?

Your bank accounts through Plaid, plus Gmail, Google Calendar, Notion, Slack, Linear and GitHub. You connect an account once and Harper works inside it from then on.

Can it move my money?

No, and not because we turned it off. Harper connects read-only through Plaid, and the actions it is allowed to take are a fixed list in the code. Transfers and payments are not on that list, so adding one would take a change to Harper itself. It can see everything and move nothing.

Does it cancel things for me?

Not yet. It finds what you're paying for and tells you what a year of it costs, and it can draft the cancellation email for you to send. Pressing send is still yours.

Do I need to install anything?

No. Harper lives in iMessage. You text it, it texts you. There is no app, no dashboard, no login to forget.

When do I get access?
