Your agents do the work. You give the yes.

Approvals are the checkpoint between an agent and the outside world. Before an email goes out, a post is published, money is spent or an invoice over your limit is sent, the agent asks you on your phone. One tap and it's done.

You decide what needs your yes.

Every agent comes with sensible rules for sending, publishing, spending and deleting. Keep them, loosen them as trust grows, or tighten them for one client.

Sample setup

Billing and collectionsWeekdays at 8:00 · Xero, Gmail

ask you first

Send new invoicesBelow your limit they go out on schedule

Invoices from $3,000Set the amount in the limits below

Payment remindersFriendly first, firmer on the third notice

Void or delete an invoiceRecommended: always ask

Only owners and admins can change these rules or answer an approval.

Set the line. Below it, work flows.

Small things go out on their own. Big ones wait for you. Move the limit and watch this month's invoices sort themselves.

Ask me for invoices from $3,000

Waits for your yes0

Three levels of trust. You pick each one.

Start every agent on a short leash and give it more room as it earns it. Same email, three ways to handle it.

Inbox and calendarNorthwind wants to move Thursday's review to Friday morning. You're free from 9:00 to 12:00. It's in your morning brief.

Reads and tells you. Nothing is written or sent.

Inbox and calendarNorthwind wants Friday. I'd suggest 10:00 and move the calendar. Send this?"Hi Sara, Friday at 10:00 works. I've moved the invite. Best, Leo"

Does the work, waits for your yes.

Inbox and calendarDone: replied to Sara and moved the Northwind review to Friday at 10:00. Leo and Anna have the new invite.In your record and your morning brief

Anything on your Ask me list still waits, even here.

What you approve is what goes out.

Once you say yes, the agent sends the text it showed you. It doesn't write it again, it doesn't add a line, it doesn't change the amount.

Questions, answered.

What needs my approval?

You decide, per agent. Each agent comes with recommended approvals for sending, publishing, spending, deleting and payments from an amount you set, such as invoices from $3,000. Email replies from a connected mailbox wait for your approval by default. You can change any rule before the agent runs.

Can I approve from my phone?

Yes. Approval cards arrive on Telegram, Slack, Discord or email with Approve, Reject and Details. One tap decides. On Telegram and Slack you can also react with a thumbs up or a check mark to approve a pending card.

What happens if I don't answer?

Nothing goes out. The item waits in your inbox. If nobody decides within 7 days it is rejected and its text is dropped.

Who can approve?

Owners and admins of your workspace. If someone else taps the button or reacts to the card, it doesn't count and the card stays open for you.

Can the agent change the text after I approve it?

No. An approved email goes out exactly as you saw it. The agent sends the stored text and does not write it again.

Can I undo an approval?

For a few seconds after you tap Approve, Undo stops it from going out and puts the card back. Once it has gone out, it is out, and the record shows who approved it and when.

Do approvals work in Microsoft Teams?

Agents can post updates and summaries to Microsoft Teams. Approvals run today on Telegram, Slack, Discord and email, and in the Brainstack inbox.

Are approvals included in my plan?

Yes. Every plan includes approvals, limits and the decision record. Plans start at $99 per month, plus the AI plan your company already pays for.

Hand over the work. Keep the last word.
