Illustrative. You named Maya, so Maya owns it.

You decided it.
Now it’s in a thread somewhere.

The call lands in message 9 of 23. Nobody writes it down, and months later you pay for the same decision twice.

How it works

We know you’re busy.

So Decize runs on the email you already send: one Cc when you decide, two taps when it asks how it went. Everything else happens on its own.

  1. Your part · 1 Cc

    You Cc one address.

    Add your Decize address to the email where you make the call. No form, no tags.

  2. Automatic

    It writes the record.

    Decize drafts the title and summary, plus any owner or due date you mention, and saves it straight away.

  3. Your team’s part · 2 taps

    It asks how it went.

    About two weeks after it’s due, the owner (or you, if there isn’t one) gets an email. Tap how it went, then Save. No login.

  4. Just ask

    You get the answer.

    Ask “didn’t we try this?” with Decize on Cc. It answers you with what you decided, how it went, and the lesson.

Your team’s part: 1 Cc + 2 taps. Everything else: Decize.

Unlike tools you have to remember to open: nothing to install, no form when you decide, no login when it asks.

See each step

Next time, just ask.

Pick your line of work. Ask with Decize on the thread, and it answers you, even with clients or suppliers on it.

Common questions

What is a decision log?

A decision log is a running record of the calls a team has made: what was decided, when, by whom, why that option won, and what was expected to happen. A useful one is revisited when the result is known, so it records the outcome and the lesson, not just the choice.

What is Decize?

Decize is a decision log for teams that decide over email. Cc it on the thread where you make a call and it records what you decided and who owns it, asks the owner how it turned out a couple of weeks after it’s due, and answers the next time you ask.

Do I need to install anything?

No. Anyone on your roster can Cc or forward an email to your workspace’s Decize address.

What if my email is just discussion?

No record is made and Decize doesn’t reply. The email stays with its thread as context.

What if the thread keeps going?

If someone on your roster replies with Decize still on Cc and changes the call, such as a new date, a reversal or “done”, Decize updates that same record. A reply from a client or supplier changes nothing.

Where is my decision log stored?

In the US: AWS, N. Virginia, encrypted at rest by our database provider, Supabase. The app runs on Vercel, email delivery goes through Resend, and the AI that reads what reaches Decize, including emails that decide nothing, is Google Gemini, with Anthropic as a backup. We don’t train AI models on your decisions.

What if clients or suppliers are on the thread?

Decize replies only to you, never to them. But what reaches Decize is saved with the thread: the emails your team sends, including anything of theirs quoted in them. The AI that drafts your record reads it, and everyone on your team can see it. Their addresses on the To and Cc lines are kept with each email too. If one of them replies to all, Decize refuses that email, but its sender and subject line are recorded and listed in your workspace owner’s daily capture email. So leave Decize off threads you wouldn’t share with your whole team.

What happens when we hit our monthly limit?

New captures are refused until the 1st, or until you move up a plan. Nothing you’ve already recorded is touched.
