Slack alerts you actually have to acknowledge.

A floating bar above every window, on every Space. Each alert is a row. Rows don't go away until you click Ack.

The problem

The notification you saw is the notification you forgot.

You glance at your phone in a meeting. You see the alert. You'll deal with it after.

You don't.

By the time you remember, the customer has emailed twice, the deploy has timed out, the on-call escalation rolled to the next person, and someone's asking why nobody saw it.

The problem isn't notifications. You got the notification. The problem is forgetting.

How it works

A persistent queue you can't ignore, can't fake-clear, and can't lose track of.

Always above everything

A persistent floating bar sits flush with your menu bar, on every Space, above every window. You don't have to remember to check Slack. The queue is already there.

Doesn't go away until you Ack it

Every alert is a row. Every row stays until you click Ack. No "marked as read" tricks. No notification-dot inbox theater. Done means you decided it's done.

Ages so you feel time pass

Fresh alerts are white. After 5 minutes they go yellow. After 15, orange. After 30, red. The bar emoji reflects the worst row — 🟢 🟡 🟠 🔴 at a glance.

0–5 minWhite · fresh

5–15 minYellow · aging

15–30 minOrange · stale

30 min+Red · overdue

Click to jump into Slack

Tap any row to open the original message in your Slack client. The queue is your inbox. Slack is where you reply.

The trigger prefix

Send yourself a nag from anywhere.

Type slacknowledge: pick this up later in any Slack channel — from your phone, from a DM with yourself, from anywhere — and it lands in your desktop queue. The prefix strips. The author doesn't matter. You decide what's worth nagging yourself about.

Not yet. macOS 14+ only.

Nowhere but your Mac. SlAcknowledge connects directly to Slack from your machine — there's no SlAcknowledge backend in the middle.

Yes, for now. You create a Slack app in your own workspace and paste two tokens — we walk you through it, takes about 5 minutes. Workspace-wide install via OAuth is on the roadmap.

The app stops checking your license and stops working. Pause your subscription instead — you keep all your settings and can resume anytime.

Right now it's sold per-person. If you're interested in team licensing, email support@laserboy.com — we're tracking demand.

Stop trusting your memory.
