About OsmO

OsmO is a personal AI phone assistant for iPhone and Android. It exists for a simple reason: the phone is the last thing that still interrupts you with calls you don't want — and makes you dread the calls you have to make. OsmO fixes both ends of that.

What we believe

Your phone should work for you, not the other way around. You shouldn't lose your focus to a robocall, or your afternoon to a hold queue, or a real opportunity because an unknown number went unanswered. We built OsmO so a capable assistant handles your calls in both directions, and you only deal with what actually matters.

What OsmO does

• Answers your calls when you can't. It picks up unknown calls in a natural voice, finds out who's calling and why, screens spam and robocalls, takes a message, and texts you a transcript.
• Makes calls for you. Tell it what you need — book a table, schedule an appointment, chase a refund, or wait on hold — and it phones the business and reports back in plain text.
• Surfaces what matters. It recognizes important calls — a doctor's office, a recruiter, family — and puts them through or texts you the details.
• Puts everything in writing. Every call is transcribed and summarized, so you can read instead of listen.

How it works

OsmO runs on top of your existing phone number using conditional call forwarding — there's no new number and no SIM swap, and setup takes about a minute. It works with most US and Canadian carriers, on iPhone (iOS 15.1+) and Android. It's free to download, with an optional OsmO Pro subscription at US$4.99/month. OsmO speaks English and Spanish today, with French and German planned.

Privacy

Calls are encrypted in transit, and you control what's stored. You can review, export, or delete your transcripts and recordings at any time.

Who builds OsmO

OsmO is built by Mountainheads Private Limited. We're a small team focused on giving people back their time and attention from a phone that too often works against them. OsmO is available in the United States and Canada.
