About Us

AmISober.com is a free, science-based tool that helps you make smarter, safer decisions after drinking.

Why we built this

Every day, people make guesses about how sober they are based on how they feel. The problem is that how you feel is a poor indicator of your actual blood alcohol content. Alcohol impairs the very judgment you'd use to assess your own impairment.

We wanted to create the simplest possible tool that uses real science — not guesswork — to answer one of the most common questions people have after a night out: when can I safely drive, sleep, or function again?

Who it's for

AmISober.com is built for responsible adults who want a reliable reference point. Whether you had a glass of wine with dinner and need to drive home later, or you're planning the morning after a big night, this tool gives you an honest answer.

It's especially useful for designated drivers who drank earlier in the night, people catching early flights or morning meetings, and anyone who wants to make an informed decision rather than a guess.

Our commitment

This site will always be free, ad-supported, and independent. We don't sell your data, we don't require an account, and we don't store any of the information you enter. Everything is calculated locally in your browser and never sent to any server.

We take the responsible use of this tool seriously. The calculator is a helpful estimate — not a legal or medical determination. Please always read the disclaimer on the results page and err on the side of caution.
