What do you want to know?

Four quick answers to the four things everyone asks us first.

Curious?

How does it work?

It's a smart scale under your glass. It senses every pour as it happens, and the light turns green the moment your drink is right. The full story, in detail →

See how it works → Worth it?

What does it save me?

A cocktail out costs $14–18. The same drink from your own bottles costs about $3. Slide the numbers yourself and see what a year looks like.

Do your math → Right now

What can I make tonight?

Tap the bottles you already have at home and see what you can pour tonight. Takes twenty seconds — no signup, no email.

Check your shelf → Having people over?

Will it survive a party?

That's what it's for. Rounds for friends, a date menu for two, and a full zero-proof list for whoever's not drinking — same thirty-second ritual every time.

The premise

Every great cocktail is a matter of half an ounce.

Half an ounce separates a margarita from a mistake. For a century, that margin belonged to professionals. We put it under your glass — a stage five inches wide that senses every pour in real time.

Three parts. One pour.

Stage. Signal. Infinity.

Drinking lighter?

Know exactly what's in your glass.

Making a lighter night easy is the same trick as making a margarita perfect: exact measurement. Every recipe shows its strength up front, spritzes and session drinks pour just as beautifully, and the zero-proof menu is the real thing — not an afterthought. No streaks, no badges, nothing nudging you to pour more.

Guilt, nudges, "one more"Never
Date night in

Stay in. Make it a bar.

Two glasses, one counter, ten minutes. Pick something you both love, pour it to the light twice, and both drinks come out exactly right. Making them together is half the fun — and two rounds in, you've already beaten the bar tab.

The ritual

Thirty seconds.
Four moves.

Step 01

Set the glass

Plug in over USB-C, pair once with the Barsys AI app over Bluetooth 5.1, and set any glass on the stage.

Step 02

Pick your drink

Choose any recipe from the Barsys AI app — or customize one to your taste and save it as the house pour.

Step 03

Pour to the light

The ring guides each ingredient and turns green at the exact moment to stop. No jigger, no guesswork.

Step 04

Garnish & serve

Stir or shake as the recipe asks, garnish, done. The stage wipes clean — nothing to rinse, ever.

The library

Never make the same night twice.

1,965 drinks from the world's best bars, brands and creators — plus a full zero-proof list — all tuned to your taste in the free Barsys AI app. Tonight's drink is in there. So is next year's.

Questions

Asked & answered

Pair it with the Barsys AI app, choose a recipe, set your glass on it, and pour each ingredient as the ring guides you. When the light turns green, stop — garnish and serve.

Yes — the guided pour experience uses the free Barsys AI app on iOS and Android. It unlocks recipes, guidance, personalization, and over-the-air updates.

Any glass that sits on the 12.7 cm stage — coupe, rocks, highball, a shaker tin, even a plastic cup with a couple of ice cubes.

As long as you like. The LED never burns out, and over-the-air updates arrive while it sits on your bar.

Nothing to rinse — no pumps, pods, or tubes. Spill on it, wipe it, done.
