Where does our decision text go?

To Google Gemini, with Anthropic as a backup, whenever a Decize feature needs a model: reading a captured email, drafting a record, writing a retrospective or an answer, or checking whether a past decision is about the same thing as a new one. Our database provider finds the closest past decisions; each close pair is then checked once by the same AI provider (both titles, the newer one’s summary, the earlier one’s date, outcome and lesson) and the answer is kept. Our sub-processors include Supabase, Vercel, Google and Anthropic, Resend for mail and Dodo Payments for billing, plus TypeSafe for optional AI evaluation of emailed outcome replies, only when we switch it on. The privacy policy has the full list and is the authority, not this page.

Does Decize train anything on our decisions?

No. We don’t train AI models on your decisions.

Where is it stored, and how is it kept apart?

Your decision log is stored in the US: AWS, N. Virginia, encrypted at rest (AES-256) by Supabase, our database provider. Your workspace is walled off, with no pooling with other customers. Email delivery is handled by Resend.

Who inside our organization can see what?

Every active member can read every decision, including the original email until an owner’s Email text setting or a deletion removes it. There are no private decisions, so keep HR and pay out. Managers also get the dashboard, roster and settings; owners hold roles, billing and the workspace itself.

No. No SOC 2, no penetration test, no bug bounty. We’re in beta, and we’d rather you priced that in now.

How it works

Your team’s part: one Cc, two taps.

Here’s what happens to your email, step by step, and exactly what you do at each one. The full manual is in the docs.

Your part · 1 Cc
You Cc one address.
Add your Decize address to the email where you make the call. No form, no tags.
Automatic
It writes the record.
Decize drafts the title and summary, plus any owner or due date you mention, and saves it straight away.
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, except in a few cases, such as a replaced decision. Tap how it went, then Save. No login.
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.

Step 1Your part · 1 Cc

You Cc one address.

Cc your Decize address on the email you’re already sending.
No tags, keywords or forms. Just say what you decided.
Anyone on your roster can Cc it from their listed address.
Mail that fails your domain’s email authentication is refused, not logged.
Just discussion? No record is created and Decize doesn’t reply.

Decize never reads your inbox, only mail sent to its address. Once it’s on a thread, every message your team sends there, including any earlier text quoted in it, is stored. Replies from people outside your team are refused, and Decize keeps only their address and subject line.

Step 2Automatic

It writes the record.

Decize drafts the title and summary, plus any owner or due date you mention.
Name the owner in your email; Decize matches them to your roster.
It’s saved straight away. Nothing to review or approve.
Your email’s text is saved with the record. Attachments aren’t.
It replies with what it logged, at most once per thread a day, unless it asks you to confirm a replacement.
Clients on the thread? Decize replies only to you.
Decided this before? On all-team threads, the reply names the earlier call.

In the app you can fix the title, summary, owner and due date. A later reply on this thread with a new date or “done” updates the record by itself. A reversal, or a change from another thread, is logged as a new decision, and the reply can ask you to confirm it replaces the earlier one.

Step 3Your team’s part · 2 taps

It asks how it went.

About two weeks after the due date, the owner (or whoever logged it) gets an email.
Tap how it went, then Save. No login.
Or reply in a sentence, then tap and Save to confirm.
A note is optional. Picking how it went is enough.
Decize drafts a short retrospective, marked AI-generated. Its takeaway isn’t saved as your lesson.
With a due date, the owner (or whoever logged it) gets reminders: at most two a week, in your workspace’s working hours.
No overdue emails to the workspace owner unless you switch it on.

A few decisions aren’t asked, such as one marked In progress or Archived, or one that was replaced. The link in that email works for 30 days, and whoever holds it can record the outcome, so don’t forward it. Missed it? It asks again later, still within two a week.

Step 4Just ask

You get the answer.

Ask “didn’t we try this?” with Decize on Cc, and it answers from what you’ve logged.
It knows only the title, date, outcome and lesson of past decisions.
The answer goes to you, the person who asked.

An owner or manager can switch in-thread answers off. Browsing the log needs an account.
