FB Auto Reply started with a simple observation: the best Marketplace sellers win because they reply first. But replying first, every time, in every language, is impossible to do by hand once you're busy.

So we built an AI that reads your Facebook Marketplace inbox and answers buyers automatically — in their language, in your tone, around the clock. It runs as a Chrome extension inside your own browser, so you stay in control of what it says and when it runs.

Today it's used by car dealers and independent sellers who'd rather spend their time closing deals than typing "yes, it's still available" for the fortieth time.
